    We investigated treatment methods for habitual dislocation of the temporomandibular joint in our department and their problems. Thirty-two patients were enrolled in this study. Their mean age was 78 ± 15 years, with a range of 36 to 94 years. All patients had an underlying disease, such as cerebral infarction, dementia, Parkinson’s disease, and lateral sclerosis. The Buckley-Terry method or eminectomy were performed under local anesthesia in 26 joints of 16 patients respectively. While recurrence occurred in 5 of 16 patients (6/26 joints; 23.1%) after the Buckley-Terry method, no recurrence was detected after eminectomy (p = 0.043, Fisher’s exact test). The cause of recurrence after the Buckley-Terry method was the deformation of titanium plates. Temporarily peripheral facial nerve palsy developed in 3 of 16 patients (3/26 joints; 11.5%) treated by the Buckley-Terry method, but not in any patient treated by eminectomy. Our results suggest that eminectomy is a more useful treatment than the Buckley-Terry method for habitual dislocation of the temporomandibular joint, especially in elderly patients with underlying diseases.

    Angiosarcoma is a rare malignant tumor of endothelial cell origin that accounts for less than 0.1% of all head and neck malignancies. Although angiosarcoma can occur in the head and neck region, the most common sites are the skin of the scalp and face. The occurrence of a primary angiosarcoma in the oral cavity is extremely rare. This report describes a case of angiosarcoma of the maxillary gingiva that metastasized to the duodenum.
    A 64-year-old Japanese man consulted our hospital because of a maxillary gingival mass. The lesion was a protruded multinodular mass with a maximum diameter of 1.5 cm and was localized to the gingival mucosa of the left side of the maxilla. On the basis of histological examination, the lesion was diagnosed as angiosarcoma, and the patient received partial maxillectomy under general anesthesia, including a 2.0-cm margin of normal tissue. Immunohistochemical examination revealed that the tumor cells were positive for CD31, CD34, and vimentin, and the Ki-67 index was up to 40%.
    Although local recurrence was not detected after the initial operation, distant metastasis to the duodenum appeared after 1 year 7 months. The patient and his family refused further treatment, and we therefore provided best supportive care. The patient died 2 years 1 month after the initial operation.

    We describe our experience with an elderly woman who presented with mastication difficulty and was given a diagnosis of with myasthenia gravis.
    The patient was an 80-year-old woman. Her chief complaint was that her jaw felt heavy, making chewing difficult. This symptom did not improve even after her dentures were adjusted at another institute. An investigation was conducted at our institute, with the following results: antiacetylcholine receptor antibodies 47.4 nmol/l, waning (+) electromyography, and a positive tensilon test result.
    The patient was given a diagnosis of myasthenia gravis. Oral treatment with mestinon was initiated; however, myasthenia gravis crisis occurred 1 year later, and thymectomy was thus performed.
    Subsequently, the mastication difficulty improved.

    Retinoblastoma is a malignant tumor originally derived from the immature retina in infancy and childhood. It usually occurs in patients younger than 2 years. Although the prognosis after treatment is relatively good, the prognosis becomes poor if extraocular extension, distant metastases, or both occur. A 1 and a half-year-old male had been given a diagnosis of a retinoblastoma of the left eye and received conservative treatment. A recurrent tumor was later found, and metastatic tumors were detected in the bone marrow, femur, and mandible 6 months later. Chemotherapy was performed at that time. Thereafter, enucleation of the left eye and peripheral blood stem-cell transplantation with ultra-high-dose chemotherapy were performed. Consequently, cerebrospinal irradiation was also performed. The patient has been in remission for 6 years. The mandible has no findings of recurrence and no dysgenesis. The permanent teeth have nearly all erupted with short roots and provide good occlusion.

    The elevation of serum amylase is generally associated with diseases of the pancreas or salivary glands. However, hyperamylasemia has also been noted to occur in a variety of conditions, such as amylaseproducing cancers, chronic viral liver disease, macroamylase, and after various surgical procedures. We describe a man in his fifties who was given a diagnosis of idiopathic salivary hyperamylasemia. He was referred to our clinic because of hyperamylasemia lasting over a 2-year-period, during which the patient remained asymptomatic. Blood examination at presentation revealed pancreatic and salivary amylase levels of 47 U/L and 626 U/L, respectively. No abnormal findings except for a kidney stone and renal atrophy were detected on further examinations, including abdominal ultrasonography, magnetic resonance cholangiopancreatography, magnetic resonance imaging of the salivary glands, and positron emission tomography-computed tomography. Furthermore, macroamylase was not detected on electrophoresis of serum amylase. On the basis of these results, idiopathic salivary hyperamylasemia was diagnosed. One and a half years later, serum levels of salivary amylase are still high.

    Inverted papilloma of the nasal cavity and paranasal sinuses is a relatively uncommon benign tumor. Because of the aggressive nature and risk of recurrence of the tumor, complete resection is essential.
    We report a patient with a massive inverted papilloma of the maxillary sinus who was surgically treated by a collaborative medical team approach, including otorhinolaryngology specialists and oral surgeons. The patient was a 50-year-old woman who consulted an otorhinolaryngologist at a primary care center in early June 2010 because of left nasal obstruction. A left nasal polyp was resected. The histopathological diagnosis was an inverted papilloma.
    In early July 2010, she was referred to the Division of Otolaryngology at Ebina General Hospital. Computed tomography revealed a mass of different density in the left maxillary sinus and nasal cavity. The clinical diagnosis was a suspected massive inverted papilloma of the left maxillary sinus.
    In mid-July 2010, otorhinolaryngology specialists were consulted and resection of the tumor was considered difficult by endoscopic sinus surgery (ESS) alone. In September 2010, the patient underwent tumor resection combined with the Caldwell-Luc operation under general anesthesia in collaboration with our department. The histopathological diagnosis was an inverted papilloma.
    No recurrence has occurred as of 36 months after the operation.
