Surgical Treatment for Masticatory Muscle Tendon-Aponeurosis and Coronoid Process Hyperplasia : A Case Report
Author:AIZAWA Hitoshi;YAMADA Shin-ichi;SAKAI Hironori;KONDOU Eiji;KURITA Hiroshi
Abstract:A 46-year-old woman was referred to our hospital seeking treatment for limited mouth opening. Restriction of mouth opening was first noticed 6 years ago, after treatment of a cervical spine bone fracture. She had a maximum mouth opening of 25mm, with slightly limited lateral and anterior mandibular movement. The patient had a square face with prominent masseter muscles and mandibular angles. A dense band of tissue, which became taut during maximal opening, was palpable along the anterior border of both masseter muscles. 3DCT images (bone window) showed bilateral hyperplasia of the coronoid process. MR imaging revealed thickened aponeurosis extending far into the anterior margin of the masseter muscles.
The clinical diagnosis was restricted mouth opening due to bilateral hyperplasia of the masseter muscle aponeuorsis and coronoid process. Masseter muscle myotomy with aponeurectomy and coronoidectomy were performed bilaterally by an intraoral approach. The mouth opening improved to 53mm immediately after the surgery. The postsurgical course was uneventful and she maintained a maximal range of mouth opening of 40mm without pain and occlusal change.

A case of intraosseous spindle cell squamous cell carcinoma of the mandible

Abstract:Spindle cell squamous cell carcinoma is characterized by multiplication of polygonal cells, mainly spindle cells, and is classified as a particular kind of squamous cell carcinoma. We report a rare case of spindle cell squamous cell carcinoma of the mandible that was considered an intraosseous carcinoma.
A 67-year-old man had undergone enucleation of a mandibular tumor (30×15mm radiolucent mass including an impacted third molar). There had been no abnormal symptoms in the oral mucosa. Pathological examination of the surgical specimen revealed that the lesion was spindle cell squamous cell carcinoma, and so the patient was referred to the Department of Dentistry and Oral Surgery, Shinshu University School of Medicine for further treatment. Elective neck dissection, segmental mandibulectomy, and reconstruction with metal plate and recto-abdominal myocutaneous free flap were carried out, followed by adjuvant chemoradiotherapy. There has been no evidence of recurrence for 5 years.

A case of multiple oral mucosal ulcers suspected to be related to oral bisphosphonates
Journal of The Japanese Stomatological Society,70(3):262-266 2021
Abstract:BPs-Related Osteonecrosis of the Jaw(BRONJ) is widely known as a common side effect of oral bisphosphonate (BP) preparations. However, mucosal damage due to local irritation in the upper gastrointestinal tract, including the oral cavity, has also been reported. Here, we report a case of multiple oral mucosal ulcers suspected to be associated with oral BP retention in the mucosa. A 78-year-old woman was hospitalized for anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis and was taking prednisolone. Her medical history revealed scleroderma, interstitial pneumonia, and mild cognitive impairment. Four days after starting oral alendronate, she was referred to our department because of oral pain. Clinical examination revealed multiple oral mucosal ulcers on the left buccal mucosa and bilateral tongue margin. Since her oral condition was poor, active oral care intervention and topical application of steroid ointment was applied. However, the oral mucosal ulcer was exacerbated. We suspected that the oral ulcers were caused by stagnation of oral BP tablets due to her cognitive decline and so requested the prescribing doctor to discontinue the alendronate. Fifteen days after discontinuation, a part of the ulcer started to become epithelized and the ulcer disappeared two months after the discontinuation.

A case of multiple facial fractures resulting in atelectasis due to bronchial obstruction by tooth fracture fragment
Journal of The Japanese Stomatological Society,70(3):273-277 2021
Author:AKITA Daisuke;KONDO Eiji;HASHIDUME Masao;OTAGIRI Hiroki;YAMADA Shin-ichi;KURITA Hiroshi
Abstract:We report a case of bronchial obstruction by a tooth fracture fragment in a patient with multiple facial fractures. A 44-year-old woman fell from a condominium and was transported to our hospital. She had multiple bone fractures including maxillofacial lesions (multiple mandibular and maxillary, multiple rib, pelvic, right femoral condylar, and sternal fractures). On the second day, chest radiographs showed the onset of atelectasis in the right upper pulmonary field, but the oxygenation was within normal range. On the seventh day, she underwent surgical reduction and fixation of the fractures under general anesthesia. Postoperative chest X-ray showed enlarged atelectasis, and immediate bronchoscopy revealed a foreign body in the right bronchus. On CT images, a thin-shaped foreign body was confirmed in the right main bronchus. The foreign body in the airway was successfully removed under bronchoscopy; it was found to be a fractured tooth fragment, which was thought to have been aspirated by the patient at the time of injury. The patient recovered thereafter and is making good progress.
