Variations of the branches of the external carotid artery are well known. Commonly, the occipital artery arises from the posterior aspect of the external carotid artery, but it is rarely reported for the occipital artery to arise from the internal carotid artery or carotid bifurcation. It is important to know the variations of the carotid arteries and their branches before invasive procedures to avoid complications. We hereby report the occipital artery arising from the superior aspect of the carotid bifurcation as a rare anatomical variant.

ABSTRACT: The extraoral approach with the risk of facial nerve injury and the visible scar is commonly performed for an elongated styloid process, because intraoral styloidectomy is challenging for the deep and limited surgical field. The authors report minimally invasive intraoral styloidectomy using an endoscope with tissue retractor. A 57-year-old female was referred to our department with a left pharyngeal foreign body sensation and pharyngeal pain after head turning and neck compression. Clinical and radiological diagnosis was an elongated styloid process (Eagle syndrome). Because the styloid process could be palpated intraorally, the patient underwent endoscopically-assisted intraoral styloidectomy without tonsillectomy under general anesthesia as minimally invasive surgery. The styloid process was resected safely with a piezoelectric surgical device under endoscopic guidance. The postoperative course was uneventful without complications.

ABSTRACT: The purpose of this study was to investigate the clinical anatomy of the feeding artery of the submandibular gland (SMG). A total of 199 SMG removals were performed in extraoral or intraoral approach with/without endoscopic assistance by a single surgeon. The feeding artery of the SMG was always identified intraoperatively and recorded in the operation record. The clinical anatomy of the feeding artery of the SMG was investigated based on the intraoperative findings. The facial artery was ligated and transected for the involvement of tumor or severe inflammation in 16 (8.0%) procedures. The feeding artery was investigated in the remaining 183 procedures. The mean number of the glandular branch was 1.5. There were 1 branch in 98 procedures (53.6%), 2 branches in 80 procedures (43.7%), and 3 branches in 5 procedures (2.7%). Detailed anatomical knowledge of the feeding artery of the SMG is useful for proper dissection of the SMG and preservation of the facial artery.

PURPOSE: Radioisotope (RI) tracers are generally used for preoperative mapping of sentinel lymph node (SLN) and intraoperative detection with a portable γ probe. However, the use of RI has several limitations. Therefore, a method without RI is required for the widespread application of SLN biopsy. The purpose of this study was to evaluate the feasibility of SLN biopsy with a handheld cordless magnetic probe following magnetic resonance lymphography (MRL) using superparamagnetic iron oxide (SPIO) and for clinically N0 early oral cancer. MATERIALS AND METHODS: MRL using SPIO and SLNB with the handheld cordless magnetic probe were performed for 27 patients with clinically N0 early oral cancer. RESULTS: In all 27 patients (100%), SLNs were detected by MRL, and the total and mean number of SLNs were 73 and 2.7, respectively. All SLNs identified by MRL were detectable using the magnetic probe in all patients. CONCLUSIONS: SLNB with handheld cordless magnetic probe following preoperative SLN mapping by MRL using SPIO is feasible, without RI use, for neck management in cases of clinically N0 early oral cancer.

ABSTRACT: The purpose of this study was to investigate the anatomical relationship between the lingual nerve and submandibular duct. This study included 1403 patients with submandibular or sublingual gland diseases who underwent intraoral removal of submandibular gland sialoliths, submandibular glands, or sublingual glands. Of all patients, 33 patients underwent bilateral surgeries. All surgeries were performed a single surgeon, and the anatomical relationship between the lingual nerve and submandibular duct was always identified intraoperatively and recorded in the operation recorded. The anatomical relationship was investigated based on the intraoperative findings. The lingual nerve which crosses above the submandibular duct was detected in 8 of 1436 sides (0.6%). There were 4 in the right sides and 4 in the left sides. The lingual nerve below the submandibular gland was seen in 99.4%. Although the lingual nerve crosses above the submandibular duct with a rarer incidence, surgeons should beware of injuring the lingual nerve during intraoral salivary gland surgery.

In oral and maxillofacial surgery such as orthognathic surgery and open treatment of maxillofacial fracture, plate fixation is commonly performed. Although the removal of titanium miniplates is controversial, the plates are removed routinely or symptomatically. By excessive torque during the screw removal, stripping or breaking of screw heads may occur. Although miniplates and screws are used with angled screwdrivers for osteosynthesis in bilateral sagittal split osteotomy (BSSO) or open treatment of mandibular angle or subcondylar fracture, the removal of a damaged screw, especially with the angled screwdriver, is very difficult. Therefore, we report a simple method with a sterilized surgical glove for removal of the stripped screw.

Background: Osteochondromas of the mandibular condyle show facial asymmetry and malocclusion. Because condylar osteochondromas are generally resected in a preauricular approach with risks of facial nerve injury and visible scar, the authors report endoscopically assisted intraoral resection of osteochondroma of the mandibular condyle with a piezoelectric surgical device.Case presentation: A 38-year-old woman presented with malocclusion and facial asymmetry caused by deviation of the chin to the left. Computed tomography showed a hyperdense, well-circumscribed mass arising from the medial aspect of the right mandibular condyle with resorption of the skull base. The patient underwent an endoscopically-assisted intraoral condylectomy with a piezoelectric surgical device. The postoperative course was uneventful without trismus, malocclusion, or facial asymmetry, and there was no recurrence 4 years after surgery.Conclusion:Endoscopically assisted intraoral resection of osteochondroma of the mandibular condyle with a piezoelectric surgical device is a minimally invasive and safe surgery.

Objectives: The purpose of this pilot study was to evaluate the usefulness of magnetic resonance lymphography (MRL) with superparamagnetic iron oxide (SPIO) in sentinel lymph node (SLN) mapping of clinically N0 early oral cancer, and to conduct a comparative study of this MRL with CT lymphography (CTL).Methods: CTL and MRL were performed for SLN mapping before surgery for 20 patients with clinically N0 early oral cancer. The detection rate, number, and location of SLNs in CTL and MRL were evaluated. Furthermore, optimal scanning/imaging timing in MRL was examined.Results: SLNs were detected by CTL in 18 (90%) patients, and the total and mean number of SLN were 35 and 1.8, respectively. All SLNs could be detected 2 min and 3.5-5 min after contrast medium injection. In all patients, SLNs were detected by MRL at 10 min after SPIO injection, and the total and mean number of SLN was 53 and 2.7, respectively. MRL at 30 min after the injection showed additional 18 secondary lymph nodes.Conclusion: MRL with SPIO is safe and useful imaging for the detection of SLNs in clinically N0 early oral cancer, and the optimal imaging timing is 10 min after SPIO injection.

Objective The purpose of this study was to reevaluate preoperative computed tomography lymphography (CTL) and enhanced CT images during follow-up to clarify whether SLNs enhanced by CTL were identified accurately before primary surgery with sentinel lymph node biopsy (SLNB) for clinically N0 early oral cancer. Methods Thirty two early oral cancer patients without cervical lymph node metastasis were enrolled in this study. To clarify whether SLNs enhanced by CTL were identified accurately before primary surgery with SLNB, we reevaluated preoperative CTL and enhanced CT images during follow-up in all patients. Results SLNs were detected by CTL in 31 of 32 patients (96.9%). During follow-up after primary surgery with SLNB, 4 of 27 patients without SLN metastasis had occult neck metastasis. Of the 4 patients, only 1 patient with cancer of floor of the mouth had overlooking of SLN, and the overlooking rate of SLN was 3.1%. The overlooked small SLN (2.9 x 3.3 x 3.1 mm) was located at contralateral level IB. The CT numbers before, 2, 5, 10 min after iopamidol injection, were 33 HU, 37 HU, 62 HU, 52 HU, respectively. The CT numbers of overlooked SLN 5 and 10 min after the injection was higher than CT images scanned before the iopamidol injection. Conclusions The enhancement of SLNs in CTL images after iopamidol injection should be compared sufficiently with CT images before iopamidol injection to avoid overlooking of SLNs in N0 early oral cancer.

Mucoceles originating in submandibular gland (SMG) which are extravasation type are extremely rare. Because the extraoral approach with potential risks of facial nerve injury and scar formation is commonly performed, we report endoscopically-assisted intraoral removal of submandibular gland mucocele as minimally invasive surgery. A 28-year-old female was referred to our department with an eight-week history of left submandibular painless swelling. Radiological diagnosis was not plunging ranula but SMG mucocele. The patient underwent endoscopically-assisted intraoral removal of SMG under general anesthesia as minimally invasive surgery. A mucosal incision on the left oral floor was made. After soft tissues surrounding the SMG were dissected bluntly, the mucocele and SMG were exposed more prominently by digital pressure applied beneath the lower border of the mandible by an assistant. The SMG was gripped with forceps after aspiration of mucocele, and pulled up through the incision by gland dissection. Because the facial artery penetrated the SMG, the facial artery was ligated and cut. The SMG with mucocele was removed completely in intraoral approach. Although there was no continuity with SMG and sublingual gland (SLG), the SLG was also removed preventively. The pathological diagnosis was SMG mucocele. Although lingual nerve paresthesia occurred postoperatively, the paresthesia was recovered completely 3 weeks after surgery. There was no recurrence 2.5 years after surgery. Because intraoral removal of SMG can be performed without cervical scar and facial nerve injury, this intraoral approach with endoscopic assistance can be an alternative to transcervical approach.

Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin B-cell lymphoma, with three subtypes: endemic, sporadic, and human immunodeficiency associated subtypes. Endemic BL typically involves the mandible, maxilla, and abdomen, whereas sporadic BL usually presents as an abdominal mass involving the mesenteric lymph nodes or ileocecal region, and jaw involvement is uncommon. In pediatric patients, oral BL commonly presents as facial swelling with an intraoral exophytic mass and is usually accompanied by mobile, displaced, and/or painful teeth. We report sporadic BL initially presented as orofacial manifestations in an 8-year-old boy, and conduct a mini-review. He had left facial and gingival swelling. CT revealed the lesions were located at the left anterior maxilla and the masticator muscle, and PET showed multiple lesions. An incisional biopsy of left anterior maxillary gingiva was performed, and the pathological diagnosis was BL. Oral management has been performed since initial chemotherapy, and tumor remission was achieved by chemotherapy with the B-NHLO3 study regimen at our pediatric department. There was no recurrence of the tumor 5 years after chemotherapy. Dentists and oral surgeons should be aware that dental problems including floating teeth and/or alveolar bone resorption might be the first clinical manifestation of BL. Because the success of intensive treatment relies on good supportive care, oral management plays an important role to maintain oral hygiene. (C) 2020 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

Vascular anomalies in infants and children were separated into hemangiomas and vascular malformations based on their clinical appearance, histopathologic features, and biologic behavior. Whereas vascular malformations are structural abnormalities of capillary, arterial, venous, or lymphatic elements, vascular tumors are characterized by increased endothelial cell turnover. However, misdiagnoses and misperceptions persist around the use of the term hemangioma: Although venous malformations arising in the submandibular gland are extremely rare, the most have been diagnosed as "hemangioma". We report a rare submandibular gland venous malformation with multiple phleboliths. A 54-year-old female visited a private dental clinic for the pain of the right mandibular third molar. Panoramic radiograph showed multiple radiopaque lesions below the right mandibular angle. After the diagnosis of submandibular gland stones, she was referred to our department for the treatment. Ultrasonography showed a heterogeneous, hypoechoic lesion with multiple hyperechoic lesions and blood flow in the right submandibular gland. CT showed a well-circumscribed, heterogenous, low-density lesion with multiple calcifications in the right submandibular gland. MRI showed a lesion with signal intensity similar to that of the muscle in the right submandibular gland had multiple low signal intensity lesions on gadolinium-enhanced T1-weighted images. Radiological diagnosis was submandibular gland venous malformation with multiple phleboliths. She underwent intraoral removal of submandibular gland lesion under general anesthesia. Pathological diagnosis was submandibular gland venous malformation with multiple phleboliths. (C) 2020 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI. Published by Elsevier Ltd. All rights reserved.

Actinomycotic osteomyelitis is an aggressive and persistent disease capable of invading and destroying bone, and chronic osteomyelitis with proliferative periostitis represents new bone formation with periosteal reaction. We report a rare case of actinomycotic osteomyelitis with proliferative periostitis arising in the mandibular ramus and spontaneous bone regeneration after coronoidectomy. A 14-year-old girl was referred for swelling in the right parotid-masseteric region and severe trismus. Contrast-enhanced CT revealed that heterogenous enhancement of the right masseter muscle, and a reactive bone formation over the lateral cortex of the right mandibular ramus and osteolysis of the condyle were seen in plain CT. MRI showed that the mandibular ramus was a low-signal intensity and the reactive bone on the ramus was signal intensity similar to muscle on T1-weighted images. The lesion was clinically and radiologically diagnosed as chronic osteomyelitis of the mandibular ramus. However, a biopsy was performed intraorally under general anesthesia to rule out a malignant bone tumor, and pathological examination showed fibrous bone andActinomycesdruses. Finally, the lesion was diagnosed as actinomycotic osteomyelitis with proliferative periostitis. She underwent image-guided intraoral removal of impacted right third molar and reactive proliferative bone on the right mandibular ramus under general anesthesia. To improve trismus, coronoidectomy also was performed. After the discharge, AMPC was administrated intraorally for 7.5 months. Postoperative panoramic radiograph and CT showed the right mandibular angle resorption and coronoid process regeneration. There was no recurrence of mandibular osteomyelitis 7 years after surgery.

We report a rare case of schwannoma arising from the sublingual glandular branch of the lingual nerve radiologically masquerading as sublingual gland tumor. A 42-year-old female was referred to our department with a painless swelling in the left submandibular region. Contrast-enhanced computed tomography showed a well-circumscribed, heterogeneous low-density tumor with cystic change in the left sublingual region. Magnetic resonance imaging showed a well-circumscribed, heterogeneous sublingual tumor with low-signal intensity on T1-weighted image and high-signal intensity in T2-weighted image. The lesion was diagnosed radiologically as benign sublingual gland tumor. The patient underwent resection of sublingual gland tumor under general anesthesia. There was no definitive continuity between the tumor and the sublingual gland, and the tumor originated from sublingual glandular branch of the lingual nerve. Pathological examination of the specimen showed schwannoma with highly cellular areas (Antoni A) and hypocellular areas (Antoni B). The postoperative course was uneventful without lingual nerve palsy, and there was no recurrence 4 years after surgery.

Conventional intraoral removal of deeply impacted or ectopic mandibular third molar is challenging for limited surgical access. Because there are potential risks of inferior alveolar nerve (IAN) injury or iatrogenic mandibular fracture, several methods for the removal have been proposed. As minimally invasive and safe surgery, we report image-guided removal of deeply impacted mandibular third molar using navigation system. A 32-year-old male was referred to our department with right mandibular pain and swelling. Panoramic radiograph showed right mandibular third molar was deeply impacted and interrupted the white line of the mandibular canal. Computed tomography (CT) showed deep impacted right mandibular third molar with root projection from the lingual cortical bone, and there was resorption of lingual cortical bone and passing of mandibular nerve between roots. For mandibular navigation surgery, a resin occlusal splint with titanium markers and handle was manufactured to fix reference frame to the mandible. CT was performed preoperatively after the occlusal splint was fixed with patient's mandibular teeth, and the patient underwent image-guided removal of mandibular third molar with navigation system under general anesthesia. After reference frame was attached to the handle of the occlusal splint fixed with patient's mandibular teeth, point-based registration was performed. The crown was removed after the sectioning, and the root sectioning with calibrated bur was performed carefully to avoid injury of the IAN under navigational guidance. The roots were completely removed, and the IAN was exposed in the lingual cortical bone defect. Postoperative course was uneventful without paresthesia of the IAN.

Foreign body-induced sialolith is very rare. We report minimally invasive sialendoscopic removal of gold filament thread-induced sialolith in the duct of the parotid gland. A 51-year-old woman with recurrent swelling of the left parotid gland was referred to our hospital. She had undergone insertion of 0.1-mm-diameter gold filament threads into the subdermal skin for facial rejuvenation previously. Computed tomography showed many gold filament threads in the subdermal skin and a sialolith (9.5×4.1×7.9mm) including a gold filament thread in the left parotid duct. The patient underwent endoscopic removal of the sialolith using a 1.6-mm-diameter sialendoscope and Holmium laser under general anesthesia. The sialolith was completely removed with basket and forceps after laser fragmentation, and the broken fragments contained gold filament thread. There was no recurrence of parotid gland swelling after the removal.

With the increasing global popularity of Japanese delicacies made of raw seafood, such as sashimi and sushi, sufficient attention should be paid to the conditions caused by raw-food consumption. It is recognised that in ingesting raw squid, bacterial or planktonic toxin, and anisakid larva often cause food-poisoning and anisakiasis, respectively. Oral stings caused by sperm bag of squid are rare. A 21-year-old female had severe pain in her oral cavity immediately after eating a raw squid (Todarodes pacificus), and consulted the department of oral and maxillofacial surgery. Oral examination showed several small whitish, club-shaped foreign bodies stuck in the surface of the floor of mouth and left buccal mucosa. Because the removal with forceps was difficult due to the tight attachment to the mucosa, foreign bodies were removed completely using forceps with slight incisions under local anaesthesia. The stings were diagnosed as a sperm bag of squid.

Purpose: This study evaluated the usefulness of sentinel lymph node (SLN) biopsy with preoperative computed tomographic lymphography (CTL) and intraoperative indocyanine green (ICG) fluorescence imaging for NO early tongue cancer.Methods: Twenty-seven patients with NO early oral tongue cancer underwent CTL with a 128-slice multidetector row CT scanner to detect SLN on the day before resection of primary tumor and SLN biopsy under ICG fluorescence guidance. We identified the location and number of SLNs mapped by CTL and evaluated whether CTL-enhanced SLNs could be identified intraoperatively as ICG fluorescent lymph nodes. Prognosis was also evaluated.Results: SLNs were detected by CTL in 26 of 27 patients (96.3%). The total and mean numbers of SLNs were 41 and 1.5, respectively. All SLNs enhanced by CTL could be identified intraoperatively as ICG fluorescent lymph nodes. Two SLNs were found under ICG fluorescent guidance in only one patient without SLN enhanced by CTL. Among the 27 patients, five (18.5%) had SLN with metastasis. Median follow-up was 76 months (range 44-82 months). During follow-up, three of 22 patients without SLN metastasis had occult cervical lymph node metastasis. The 5-year overall survival rate was 100%.Conclusion: SLN biopsy with preoperative CTL and intraoperative ICG fluorescence imaging is a feasible and reliable procedure, without radioisotope tracers, for neck management in cases of early tongue cancer.

Background The objectives of this retrospective study were to evaluate the usefulness of computed tomography lymphography (CTL) and to clarify the optimal timing of CTL in sentinel lymph node (SLN) mapping of clinically N0 early oral cancer. Methods Twenty patients with clinically N0 early oral cancer underwent CTL with a 128 multi-detector row CT scanner to detect SLN the day before resection of primary tumor and SLN biopsy with indocyanine green (ICG) fluorescence guidance. CT scanning was performed in the first 10 patients at 2, 5, and 10 min after submucosal injection of iopamidol and in the remaining 10 patients at 2, 3.5, 5, and 10 min after the injection of contrast medium. We evaluated the SLN detection rate at each scan timing and the number and location of SLNs. We evaluated whether CTL-enhanced SLNs could be identified intraoperatively as ICG fluorescent lymph nodes. Results SLNs were detected by CTL in 19 of the 20 patients (95.0%), and the mean number of SLNs was 2 (range, 1-4). All SLNs were located on the ipsilateral side; 35 of 37 SLNs were located at level I and II, and 2 SLNs were lingual lymph nodes. All SLNs could be detected 2 min and 3.5-5 min after contrast medium injection, and CTL-enhanced SLNs could be identified intraoperatively as fluorescent lymph nodes. Conclusions CTL could facilitate the detection of SLNs in early oral cancer, and the optimal timing of CT scanning was at 2 and 5 min after injection of contrast medium.

Objective: Intra-oral minor salivary gland tumors are relatively rare. This study aimed to clarify the frequency and distribution of infra-oral minor salivary gland tumors in Japanese patients.Methods: We retrospectively analyzed the histopathological records of 131 patients with minor salivary gland tumors that were surgically treated between 1967 and 2017 at a single institution.Results: Of the 131 minor salivary gland tumors, 61 (47%) were benign and 70 (53%) were malignant. The male:female ratio was 1:1.8 for benign cases and 1:1 for malignant cases. Most of the tumors occurred in the palate, followed by the floor of the mouth. The most frequent minor salivary gland tumor was pleomorphic adenoma among benign tumors and adenoid cystic carcinoma among malignant tumors. The rarest minor salivary gland tumors were Warthin tumors and basal cell adenocarcinoma, accounting for only 0.8% of all cases.Conclusions: The present study determined the incidence rates of these rare tumors.

Migration of sialoliths is extremely rare and is presumed to be a consequence of abscess formation. We report a minimally invasive, ultrasound-guided, extraoral approach for the removal of extraparenchymal sialoliths caused by acute parotitis. A 57-year-old man with left buccal swelling and pain had two parotid sialoliths. Buccal undulation was present after administration of antibiotics, and ultrasound showed extraparenchymal sialoliths. The migrated sialoliths from the parotid gland could be identified easily under ultrasound guidance and removed completely with long mosquito forceps via the small skin incision.

Osteomas are benign, slow-growing osteogenic tumors that consist of compact or cancellous bone. They sometimes arise from the craniomaxillofacial region. Among the peripheral, central, and extraskeletal types, peripheral osteomas arise from the periosteum, usually as unilateral, pedunculated, mushroom-like masses. Here, we report an unusual peripheral osteoma arising from the lateral surface of the mandibular ramus. A 57 year-old woman with a mass at the left mandibular ramus was referred to us. The hard and immobile mass had been growing for 15 years, and she had facial asymmetry. She had no trismus, temporomandibular joint dysfunction, previous facial trauma, or infection. Computed tomography showed a mushroom-like lesion (21.1 x 13.4 x 13.1 mm) arising from the lateral surface of the left mandibular ramus. Clinical diagnosis was peripheral osteoma. The lesion was removed using rotary instruments and a chisel through an intraoral approach under general anesthesia. The lesion had intruded into the masseter muscle. Pathological diagnosis was compact osteoma. The postoperative course was uneventful and there has been no recurrence 1.5 years after surgery.

Obstructive sialadenitis of the submandibular gland is commonly caused by sialoliths, but more rarely by foreign body-induced sialoliths. Here, we report minimally invasive sialendoscopic removal of fish bone-induced sialoliths in the duct of the submandibular gland. A 43-year-old woman presented with recurrent swelling of the right submandibular gland at other hospital. Computed tomography (CT) showed an 8-mm linear calcification in the posterior part of Wharton's duct. The lesion was deemed difficult to remove and she was followed up. However, because the lesion did not resolve spontaneously within 9 months and chronic sialadenitis symptoms persisted, she was referred to our department for endoscopic removal. CT showed a linear calcification (5.6 x 1.2 x 0.8 mm) connecting 2 spherical calcifications (2.3 x 2.1 x 1.9 mm; 1.8 x 1.4 x 1.1 mm) in the anterior part of Wharton's duct. The patient underwent endoscopic removal of the lesion using a 1.6-mm-diameter sialendoscope under local anesthesia. The specimen contained a fish bone connecting 2 sialoliths. The patient was unaware of the fish-bone injury. After removal, there was no recurrence of submandibular gland swelling during 6 months follow-up. (C) 2017 Elsevier B.V. All rights reserved.

Intraoral removal of a submandibular gland stone is less invasive than submandibulectomy, with no life-threatening airway complications reported until now. We report a case involving airway obstruction caused by pharyngolaryngeal swelling after intraoral removal of a submandibular gland stone. A 31-year-old man with a left submandibular gland stone underwent intraoral removal of the stone under general anesthesia and was discharged I day after surgery. That night, he was transported back to our hospital by ambulance for dyspnea. Because computed tomography showed pharyngolaryngeal swelling, he was intubated and managed by a ventilator. Four days later, the pharyngolaryngeal swelling had mostly resolved and he was extubated and discharged. Surgeons should be vigilant of the potential risk of airway complications following an intraoral approach for submandibular gland stone removal.

Objective: As the first step in sialendoscopy, the orifice of the salivary duct is progressively dilated using different sized salivary probes before the sialendoscope is inserted. However, the procedure can be challenging as surgeons may lose the duct orifice and find it difficult to re-identify after each probe change. To overcome this problem, we previously reported a simple technique using a guidewire, but a more cost-effective and time-saving approach is needed. We describe a modified method for simple dilatation of the papilla orifice to introduce the sialendoscope easily into the ductal lumen.Methods: A 24 G angiocatheter and a 0.5-mm-diameter salivary or lacrimal probe is prepared preoperatively. The tip of the angiocatheter (3.3-0.7 mm outer diameter) is cut and the probe is threaded into the tapered catheter. On identifying the duct orifice by pressing the salivary gland, they are inserted together into the duct orifice. Only the catheter is advanced into the duct along the probe to dilate the orifice. The orifice can be easily dilated without losing the papilla entrance. After removing the catheter, a sialoendoscope can be inserted easily into the duct.Results: We performed more than 100 procedures using this modified method and the sialendoscope could be inserted into the duct within 10 s after probe insertion into the orifice.Conclusion: This method offers simple dilatation of the papilla orifice to introduce the sialendoscope.

Facial nerve paralysis (FNP) after super-selective intra-arterial chemotherapy (SSIAC) is a relatively rare local side effect of SSIAC to the maxillary artery (MA) or the middle meningeal artery (MMA). The incidence and prognosis of FNP after SSIAC in 381 patients with oral cancer (133 with catheterization of the MA, 248 without) was investigated retrospectively. Only three patients (two male and one female) had FNP, for an incidence of 0.8%. All patients with FNP had undergone catheterization of the MA, and the incidence of FNP in this group was 2.3% (3/133). One of the three patients with FNP had paralysis of the third branch of the trigeminal nerve. FNP occurred a mean of 8.7 days (range 5-11 days) after initial SSIAC, and the mean total dose of cisplatin was 55.8 mg (range 42.5-67.2 mg) and of docetaxel was 25.4 mg (range 17.0-33.6 mg). FNP resolved completely a mean of 12.7 months (range 6-19 months) after onset. Because the administration of anticancer agents via the MA or MMA carries a risk of FNP, this information will be useful when obtaining informed consent from patients before treatment.

症例は49歳男性で、左側頬部に疼痛を伴う強い腫脹を認めたため、他院耳鼻咽喉科・頭頸部外科を受診した。CTなどの画像検査が行われ、左側耳下腺唾石症および急性化膿性耳下腺炎と診断された後、抗菌薬の投与が行われた。消炎治療後、内視鏡下での低侵襲な治療を希望され当科紹介受診となった。反復する炎症により、初診時点ですでに唾石が導管外に逸脱していた可能性を考慮し、手術はまず唾液腺内視鏡で導管内を観察し、唾石が導管外に逸脱している場合には皮膚自壊部を切開して口外法で唾石摘出する方針とした。術中所見より唾石が導管内の肉芽形成部より導管外に逸脱したものと考え、口外法での唾石摘出術に切りかえた。術後2ヵ月目には皮膚の炎症症状は完全に消失し、左側耳下腺開口部より良好な唾液の流出が認められた。

A 56-year-old man with right parotid swelling was referred to our department for endoscopic removal of a parenchymal sialolith of the parotid gland. Computed tomography showed that the parenchymal sialolith measured 3.6 × 2.5 × 1.7 mm. Diagnostic sialendoscopy was performed with the patient under local anesthesia, and the parenchymal sialolith was found in the endoscopic view. Therefore, the patient underwent endoscopic removal of the sialolith under general anesthesia as minimally invasive surgery. Complete removal was performed using a microbur and basket, and the postoperative course has been uneventful for 1 year 9 months.</p>

Warthin tumor is a benign salivary gland tumor which usually occurs in the parotid gland, but rarely in the cervical lymph node. We report a Warthin tumor in a contralateral parotid gland lymph node that mimicked metastasis of oral floor cancer on FDG-positron emission tomography/computed tomography （PET/CT）. For treatment of oral floor cancer, a man in his 70s was referred to our department. CT showed a 14×11×9mm mass below the contralateral parotid gland. FDG-PET/CT showed abnormal accumulation （SUVmax＝4.7） of FDG in the mass. Because differential diagnosis of lymph node metastasis and Warthin tumor was difficult, CT lymphography （CTL） was performed. Although CTL revealed one sentinel lymph node in the right submandibular region, there was no lymphatic flow to the contralateral parotid lymph node. Therefore, the patient underwent tumor resection and biopsy of both lymph nodes. The pathological diagnosis of the contralateral parotid lymph node was Warthin tumor. There was no evidence of recurrence and metastasis 11 months after surgery.

60代男性。左側耳下腺導管内唾石症と診断され、内視鏡下唾石摘出術を行う予定であった。しかし、初診から3週間後、左側頬部の腫脹や硬結の増大を認め、その中央部は自潰していた。自潰部からは排膿を認めたため、抗菌薬による消炎処置を継続したところ、1週間後に唾石と思われる石灰化物2個が自潰部から自然排出した。エコーでも唾石の残存がなく、1ヵ月経過後には左側頬部の腫脹は消失し、自潰部は完全に閉鎖していた。本例は、唾石に感染を併発したことで膿瘍が形成され、導管外の膿瘍腔へ唾石が逸脱し、皮膚瘻孔からの排膿とともに唾石が自然排出されたと考えられた。
