歯原性角化嚢胞は歯原性上皮から生じる嚢胞性疾患の一種であり,高い浸潤性や再発傾向など腫瘍に類似した性格を特徴とする.外科的治療が唯一の治療法であり,摘出術を第一選択とするが,多発再発例や後方進展例は根治性の確保のため顎骨切除が考慮されうる.今回われわれはナビゲーションシステムを用いて摘出術を行い顎骨温存を可能とした上顎歯原性角化嚢胞再発症例について報告する.症例は57歳の男性,前医で上顎骨嚢胞の診断で摘出術を受けた.病理検査にて歯原性角化嚢胞と診断され,術後2年の画像検査で眼窩底近傍および口蓋骨錐体突起部に多発再発を認めた.顎骨切除が提案されたが,顎骨温存を希望し当科紹介された.再発病変が上顎骨内深部に存在し重要臓器に近接していたことから,病変のリアルタイムでの位置評価のためナビゲーションシステムを用いた嚢胞摘出術が実施された.術中ナビゲーションは三次元的な病変の同定を正確かつ安全に可能とし,嚢胞摘出術と周囲骨の削除は周辺臓器や神経血管束の損傷なしに行われた.術後合併症もなく経過は良好で,術後14か月経過した時点での骨形成は良好で病変の再発は認めなかった.(著者抄録)

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。

© 2020 Asian AOMS(+) ASOMP(+) JSOP(+) JSOMS(+) JSOM(+) and JAMI 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.

Superselective intra-arterial chemotherapy (SSIAC) for oral cancer can deliver a higher concentration of anticancer agent into a tumor-feeding artery than intravenous systemic chemotherapy. However, the agent distribution between the lingual artery and facial artery (FA) is not clear in SSIAC for patients with the linguofacial trunk. The agent distribution in the SSIAC method was investigated using computational fluid dynamics (CFD). Ten three-dimensional vessel models were created from CT images of two patients with oral cancer (patients A and B) with the linguofacial trunk. Catheter models were combined with vessel models to mimic intra-arterial infusion, and the agent flow was analyzed. In patient A models, the agent distribution varied depending on the catheter tip position in the linguofacial trunk, while all anticancer agents flowed into the FA only in patient B models. This study revealed that the behavior of the agent in the common trunk is determined by the blood flow field which depends on the topography of the vessels in each patient. Therefore, the catheter tip position should be changed according to the vessel topography to deliver anticancer agents into the tumor-feeding artery. Moreover, CFD can be a useful method to predict the agent flow for each patient before SSIAC.

Ultraviolet treatment of titanium implants makes their surfaces hydrophilic and enhances osseointegration. However, the mechanism is not fully understood. This study hypothesizes that the recruitment of fibrinogen, a critical molecule for blood clot formation and wound healing, is influenced by the degrees of hydrophilicity/hydrophobicity of the implant surfaces. Computational fluid dynamics (CFD) implant models were created for fluid flow simulation. The hydrophilicity level was expressed by the contact angle between the implant surface and blood plasma, ranging from 5° (superhydrophilic), 30° (hydrophilic) to 50° and 70° (hydrophobic), and 100° (hydrorepellent). The mass of fibrinogen flowing into the implant interfacial zone (fibrinogen infiltration) increased in a time dependent manner, with a steeper slope for surfaces with greater hydrophilicity. The mass of blood plasma absorbed into the interfacial zone (blood plasma infiltration) was also promoted by the hydrophilic surfaces but it was rapid and non-time-dependent. There was no linear correlation between the fibrinogen infiltration rate and the blood plasma infiltration rate. These results suggest that hydrophilic implant surfaces promote both fibrinogen and blood plasma infiltration to their interface. However, the infiltration of the two components were not proportional, implying a selectively enhanced recruitment of fibrinogen by hydrophilic implant surfaces.

Background: Intra-arterial chemotherapy (IAC) for oral cancer can deliver a higher concentration of anticancer agent into a tumor-feeding artery than intravenous systemic chemotherapy. However, distribution of anticancer agent into several branches of the external carotid artery (ECA) in IAC has not demonstrated sufficient treatment efficacy. To improve the effectiveness of IAC, the flow distribution of anticancer agent into the branches of the ECA in several IAC methods was investigated using computational fluid dynamics (CFD).
Methods: Patient-specific three-dimensional vessel models were created from CT images of 2 patients with tongue cancer. Catheter models were combined with the vessel models. Thirty-two models were generated with varying vertical and horizontal positions of the catheter tip. With the use of a zero-dimensional resistance model of the peripheral vessel network, conventional IAC and superselective IAC were simulated in 30 and 2 models, respectively. The flow distribution of anticancer agent into the branches of the ECA was investigated in 32 models. Additionally, the blood streamline was traced from the inlet of the common carotid artery toward each outlet to examine the flow of anticancer agent in all models, and the wall shear stress of the vessel was calculated for some models.
Results: The CFD simulations could be conducted within a reasonable computational time. In several models, the anticancer agent flowed into the target artery only when the catheter tip was located below the bifurcation of the ECA and each target artery. Furthermore, the anticancer agent tended to flow into the target artery when the catheter tip was shifted toward the target artery. In all ECA branches that had flow of anticancer agent, the blood streamlines to the target arteries contacted the catheter tip. Anticancer agent flowed into only the target artery in patients' models for superselective IAC. However, high wall shear stress was observed at the target artery in one patient's model.
Conclusions: This CFD study showed that location of the catheter tip was important in controlling the anticancer agent in conventional IAC. The distribution rate of anticancer agent into the tumor-feeding artery tended to increase when the catheter tip was placed below and toward the target artery. Although superselective IAC can reliably supply anticancer agent to the target artery, high wall shear stress at the target artery can occur, depending on vessel geometry of the patient, which may cause serious complications during the treatment.

Granular cell tumors are rare soft tissue tumors, derived from Schwann cells. About half of them occur in the head and neck, but a case with tumor arising in the zygomatic region has not been reported to our knowledge. We report a case of granular cell tumor arising in the zygomatic region. A 57-year-old woman was referred to our hospital because of cheek swelling. MRI findings showed a benign tumor, so the patient wished follow-up. However, the tumor gradually grew in size for 11 months, as was confirmed by MRI. Since the patient desired removal of the tumor, the operation was performed by the intraoral and subcilial approach. The histopathological diagnosis was granular cell tumor. Judging from the operative finding, we supposed the origin of the tumor to be the zygomaticofacial nerve which is a branch of the maxillary nerve. Twenty-six months after the operation, there was no sign of recurrence.

Background: Patient-specific modelling in clinical studies requires a realistic simulation to be performed within a reasonable computational time. The aim of this study was to develop simple but realistic outflow boundary conditions for patient-specific blood flow simulation which can be used to clarify the distribution of the anticancer agent in intra-arterial chemotherapy for oral cancer.
Methods: In this study, the boundary conditions are expressed as a zero dimension (0D) resistance model of the peripheral vessel network based on the fractal characteristics of branching arteries combined with knowledge of the circulatory system and the energy minimization principle. This resistance model was applied to four patient-specific blood flow simulations at the region where the common carotid artery bifurcates into the internal and external carotid arteries.
Results: Results of these simulations with the proposed boundary conditions were compared with the results of ultrasound measurements for the same patients. The pressure was found to be within the physiological range. The difference in velocity in the superficial temporal artery results in an error of 5.21 +/- 0.78 % between the numerical results and the measurement data.
Conclusions: The proposed outflow boundary conditions, therefore, constitute a simple resistance-based model and can be used for performing accurate simulations with commercial fluid dynamics software.

The influence that maxillary movement gives for breathing is great, and it needs a functional evaluation. But there is not the report about stenosis of the nasal cavity with the maxillary bone upward movement. Therefore we analyzed it for the purpose of clarifying the influence that maxillo-mandibular orthognathic surgery with the maxillary bone upward movement gave for a nose breathing function.<br>By moving maxillary bone above and resecting inferior border of the pyriform aperture, the pressure drop of the nasal cavity got a result to decrease after surgery. Furthermore, it was recognized that a lot of pressure drop occurred in nasal cavity front 1/3, and the possibility that resecting inferior border of the pyriform aperture was useful from the viewpoint of nasal cavity ventilation was suggested.

We report a comparison between upper gastrointestinal fiberscopy (GIF) and ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for screening of upper gastrointestinal double cancer in patients with oral cancer.<br>Between September 2006 and August 2009, 133 patients with oral cancer underwent GIF and FDG-PET/CT before treatment. Five patients (3.8%) had synchronous double cancer in the esophagus or stomach using GIF. There were early-stage cancers in all cases. However, FDG-PET/CT could detect double cancer (esophageal cancer) in only one patient, and the sensitivity and specificity were 20% and 100%, respectively. This study proved the usefulness and necessity of GIF for screening in the upper gastrointestinal regions before treatment in patients with oral cancer.

Cervicofacial subcutaneous emphysema is a rare complication of dental procedures. Although most cases of emphysema occur incidentally with the use of a high-speed air turbine handpiece, there have been some reports over the past decade of cases caused by dental laser treatment. Emphysema as a complication caused by the air cooling spray of a dental laser is not well known, even though dental lasers utilize compressed air just as air turbines and syringes do. In this study, we comprehensively reviewed cases of emphysema attributed to dental laser treatment that appeared in the literature between January 2001 and September 2012, and we included three such cases referred to us. Among 13 cases identified in total, nine had cervicofacial subcutaneous and mediastinal emphysema. Compared with past reviews, the incidence of mediastinal emphysema caused by dental laser treatment was higher than emphysema caused by dental procedure without dental laser use. Eight patients underwent CO2 laser treatment and two underwent Er:YAG laser treatment. Nine patients had emphysema following laser irradiation for soft tissue incision. Dentists and oral surgeons should be cognizant of the potential risk for iatrogenic emphysema caused by the air cooling spray during dental laser treatment and ensure proper usage of lasers.

We report a case of cancer of the oral floor (T4aN3M0) treated successfully with thermochemoradiotherapy.<br>A male in his 60's with a mass in the oral floor was referred to our department. There was a tumor in the oral floor measuring 40 &times; 35 mm and left cervical swelling. CT images showed that the tumor had invaded extrinsic tongue muscles and its size was 42 &times; 35 &times; 30 mm, and there were also large metastatic lymph nodes from level II to IV. After the biopsy, the patient was diagnosed as squamous cell carcinoma of the oral floor (T4aN3M0). As the patient wanted to preserve oral function and refused to undergo operation of the primary site excluding neck dissection, we performed superselective intra-arterial chemotherapy via bilateral superficial temporal arteries (cisplatin: total 264 mg, docetaxel: total 144 mg) with daily concurrent radiotherapy (1.8 Gy/day, total 59.4 Gy) and thermoradiotherapy for cervical lymph node metastases (RF capacitive hyperthermia: twice). After the treatments, the primary and cervical sites became remarkably small. Although the treatment effect was complete response of the primary tumor and cervical lymph node metastases 6 weeks after the treatment, CT images revealed lung metastasis. The patient died 20 months after the initial treatments in spite of chemotherapy. During follow-up, there was no recurrence of the primary tumor or cervical lymph node metastases.

We report a case with carcinoma of the upper gingiva and N3 treated successfully with retrograde superselective intra-arterial chemoradiotherapy combined with hyperthermia.<br>A 39-year-old male with swelling of the left cervical region was referred to our department. The mass was 65 &times; 55 mm. The tumor was diagnosed as squamous cell carcinoma of the upper gingiva and cervical lymph node metastasis (T2N3M0) by radiological and pathological diagnosis. The patient underwent chemoradiotherapy using superselective intra-arterial infusion via the superficial temporal artery and occipital artery combined with hyperthermia. The total dose of cisplatin was 150 mg/m², and that of docetaxel was 60 mg/m². External irradiation was performed five times a week at 2 Gy per fraction, for a total of 60 Gy. Hyperthermia was performed 5 times for 6 weeks.<br>Pathological complete response was achieved in the primary site 1 month after the completion of the treatment. However, the clinical effect of the lymph node was partial response. Therefore, the patient underwent bilateral neck dissections and soft tissue reconstruction. The pathological diagnosis of the resected lymph node was complete response. The patient has been free of disease for 20 months. This method may be an effective treatment for cervical lymph node metastasis, N3.
