    To investigate the effect of enforced manipulation technique on arthrocentesis in patient with intracapsular adhesion of the temporomandibular joint, the clinica effectiveness of the procedure was compared on the basis of arthoscopic findings between an enforced manipulation group and a matched-pair contro group. Ten patients who underwent sufficient enforced manipulation during arthrocentesis comprised the enforced manipulationtion group, and 10 patients without manipulation comprised the control group.
    One month after the procedure, the range of maximum mouth opening increased by 3 to 15 mm (mean 9.0 mm) in the enforced manipulation group, as compared with 1 to 8 mm (mean 5.3 mm) in the control group. This difference was significant. Our results indicate that the enforced manipulation technique on arthrocentesis contributes to an increased range of mouth opening in patients with intracapsular adhesion of the temporomandibular joint.

    We report a cemento-ossifying fibroma containing multiple impacted teeth within the tumor, which arose in the maxilla during infancy. The dental follicles of deciduous teeth were apparently involved in pathogenesis. The patient was referred to our hospital because of multiple impacted teeth in the right maxilla as well as spontaneous pain in the right maxillary first premolar region. CT scanning revealed a large mass in the right maxillary sinus, with six impacted teeth in the tumor. The biopsy diagnosis was a cemento-ossifying fibroma. The tumor was excised under general anesthesia. The size of the tumor was 50 × 40 × 35mm. Pathological examination confirmed a cemento-ossifying fibroma. The patient remains under observation, with no evidence of recurrence.

    Neurofibroma is a benign tumor originating from Schwann cells, perineural fibroblasts, or both. It is commonly associated with neurofibromatosis (von Recklinghausen's disease), while solitary neurofibroma rarely occurs in the oral region. We report a rare case of solitary neurofibroma arising in the cheek. The patient was a 47-year-old woman who had no symptoms, except for a painless swelling in the right side of the cheek. We found neither cafe-au-lait spots nor tumors on the skin of her body. Intraoral examination revealed a solitary, mobile, welldelimited, elastic soft mass 25 mm in diameter in the cheek. CT scan revealed an enhanced tumor mass in the cheek. The tumor was surgically removed. Histopathologically, it was composed of proliferating spindle cells and collagen-like fibers. Immunohistochemical studies showed positive staining of tumor cells with S-100 protein. The histopathological diagnosis was neurofibroma. About 12 months after the operation, there is no evidence of recurrence.

    Angioleiomyoma is a benign tumor arising from perivascular smooth muscle cells. This tumor usually occurs in the lower extremities of middle-aged to elderly women, and rarely develops in the oral region. We report a case of angioleiomyoma arising in the lower lip. An 88-year-old woman was referred to our hospital because of apainless tumor of the lower lip. The clinical diagnosis was a benign tumor of the lower lip, and the tumor was surgically extirpated under local anesthesia. Microscopically, the tumor was composed of numerous capillaries surroundedby smooth muscle-like tumor cells. Immunohistochemical analysis showed positive reactions for α-smooth muscle actin (SMA) and desmin in the tumor cells. Histopathologically, the specimen was diagnosed as angioleiomyoma. Postoperative observation has revealed no recurrence as of 6 months after the operation.

    Schwannoma is a benign tumor originating from Schwann's sheath. Cellular schwannoma is one of the variants of schwannoma, which differs from conventional schwannoma and is extremely rare in the oral and maxillofacial region. We present a case of cellular schwannoma arising in the masseter muscle. The patient was a 58-year-old woman who was referred to our hospital because of swelling of the left cheek. An elastic firm mass, 30mm in diameter, was found in the left cheek. The mass was movable and slightly tender. MRI revealed a well-circumscribed mass within the left masseter muscle. Under a clinical diagnosis of a tumor in the left cheek, the lesion was extirpated under general anesthesia. The tumor was encapsulated and easily removed. It was solid, and the cut surface was yellow. Histopathological examination revealed that the tumor consisted mainly of a proliferation of spindle cells resembling Schwann's cells with an Antoni A type pattern. Verocay bodies were not observed. High cellularity and mitotic activity were characteristic features. A small area with an Antoni B type pattern was also observed. Immunohistochemically, the tumor cells were positive for S-100. On the basis of these findings, the tumor was diagnosed to be a cellular sahwannoma. Recurrence has not been observed for 1 year 4 months after surgery.

    A 57-year-old man underwent surgical excision of a skull base tumor in 1996, which was diagnosed as a granular cell tumor histopathologically. Gamma knife radiosurgery was performed for a recurrent tumor in 2000. A recurrent tumor developed from the right infratemporal fossa and underwent gamma knife radiosurgery againin 2001. He visited our department in 2002 because of swelling and pain in the left side of the mandible. Panoramic radiography revealed a radiolucency (35mm×50mm) with an ill-defined border in the body of the left side of the mandible. The histopathological diagnosis of a biopsy specimen was a malignant granular cell tumor. Radiosurgery with a Cyber knife was performed. Metastases to the liver and pancreas were detected during follow-up. Although adequate control of the metastatic site of the mandible was obtained, the patient died of arterial bleeding from necrotic tissue of the mandible and cachexia 10 months after radiosurgery with the Cyber knife.

    We describe a case of small cell carcinoma of the lung with superior vena cava syndrome as the initial sign. The patient was a 62-year-old man who was referred to our department for swelling of the facial region and dull pain of the masseter muscles. The cause of these symptoms was not odontogenic infection or temporomandibular disorders. Chest radiography revealed a large mass in the mediastinum. The mass was diagnosed as small cell carcinoma of the lung on CT scanning and cytological examination. At the completion of combined radiochemotherapy, carcinoma of the lung showed a complete response, and swelling of the facial region and dull pain of the masseter muscles disappeared. As of 30 months after radiochemotherapy, there has been no evidence of recurrence or metastasis.

    We report a case of pleomorphic adenoma of the palate associated with squamous cell carcinoma of the superficial mucosa.
    The patient was a 50-year-old man. On presentation, a 17×20-mm, painless, elastic hard tumor with a clear border was seen on the right side of the palate, accompanied by an ulcer measuring 3-mm in diameter. To avoid effects on diagnosis, biopsy was done avoiding the ulcer with inflammatory reaction. A pleomorphic adenoma was diagnosed. The tumor was excised under the diagnosis of a benign tumor. The pathological diagnosis was a pleomorphic adenoma. However, squamous cell carcinoma was confirmed in the oral mucosal epithelium covering the tumor. These two tumors were not connected.

    Sialoliths mainly occur in the major salivary glands and rarely arise in the minor salivary glands. Sialoliths in the lower lip are extremely rare.
    We report a sialolith occurring in the minor salivary gland duct of the lower lip. An 84-year-old woman was referred to our hospital because of a tumor of the right lower lip. The clinical diagnosis was a benign tumor. We performed tumor excision. There were no adhesions of the surrounding tissue, and the tumor was excised without any problems. Histologically, fragments of calcified material were seen within a dilated duct. The duct epithelium consisted of pseudostratified ciliated columnar epithelium. A minor salivary gland near the duct showed acinar atrophy and fibrosis. The histopathologic diagnosis was a sialolith in the minor salivary gland duct. The patient's postoperative course has been good, with no evidence of recurrence.

    Congenital factor X deficiency is a very rare disease. We present a case of marginal periodontitis in a patient with congenital factor X deficiency. The patient was a 53-year-old woman in whom congenital factor X deficiency was diagnosed on the detection of bloody urine. Our department was consulted by her physician because of swelling of the gingiva around the maxillary right second molar. After administering antibiotic treatment, tooth extraction was performed. The tooth socket was filled with oxidized cellulose, and the gingival defect was primarily closed, achieving good local status. However, continuous oozing from the socket of the tooth increased gradually the next day. Then, the patient was given combined Coagulation Factor Complex (PPSB-HT®), 1000 units. The factor X activity in serum increased from 7 % to 49 % the day after treatment was initiated. Although the suture was removed on the 7th postoperative day, slight persistent bleeding was observed. Bleeding stopped when thrombin liquid was sprayed over the site of bleeding and pressure was applied with gauze. There was no abnormal hemorrhage, and wound healing was uneventful.

    Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by autoantibodies against platelets.
    It is necessary for patients with ITP to increase their platelet count before tooth extraction because of an increased risk of bleeding complications.
    In 1981 Imbach et al. reported that high-dose gamma-globulin therapy could increase the number of platelets in ITP.
    Recently, this treatment has been used clinically in the oral surgical field. However, there are no clinico-statistical reports.
    We clinically analyzed 12 patients with ITP who underwent tooth extraction under high-dose gamma-globulin therapy in our hospital from 1989 through 2004.
    The results were as follows:
    1. In 10 patients (83.3%), the platelet count increased to above 5×104/μ1. In 2 patients (16.7%), there was no elevation of the platelet level.
    2. There were no severe side effects associated with therapy.
    3. We consider high-dose gamma-globulin therapy very useful for increasing the platelet count immediately before tooth extraction in patients with ITP.
