A case of surgical ciliated cyst after Le Fort I osteotomy is described. A 32-year-old man who had undergone Le Fort I osteotomy in 1992 was referred to our hospital because of swelling in the left cheek. Radiographic and computed tomographic examinations showed a unilocular cystic lesion in the left side of the maxilla. The lesion was diagnosed as a maxillary cyst. We treated the lesion surgically. The lesion and thin bony wall between the cystic cavity and maxillary sinus were removed, so that the bony cavity commuted with the inferior nasal meatus. The postoperative course was uneventful, and there was no evidence of recurrence 12 months after surgery. On the basis of the clinical course and histopathological findings of the surgical specimen (i.e., the cyst had a thick fibrous wall lined by stratified ciliated columnar or cuboidal epithelium), the lesion was diagnosed as a surgical ciliated cyst.

We report a rare case of Warthin tumor accompanied by bone formation. A 57-year-old woman with pus discharge in the right mandibular gingiva visited our hospital in August 1995. Several fistulas in the right mandibular gingiva and a rough-surfaced tumor 1.5 cm in diameter on the right side of the tongue were found. The clinical diagnosis was osteomyelitis of the mandible and tongue cancer. Sequestrotomy of the mandible and partial glossectomy were performed in October 1995. At that time, a computed tomographic (CT) scan showed 1-cm-diameter lesion in the right parotid gland; however, she hesitated to undergo surgery. In April 2001, a CT scan revealed a bilateral mass 1.2 cm in diameter near the parotid glands, and the mass in the right parotid gland increased to 2 cm in diameter and possessed a small calcified granule inside. 99mTc scintigraphy of the salivary glands showed a hot spot in the both parotid glands, consistent with the tumor. In March 2002, she underwent extirpation of the tumors arising in the both parotid glands. Histopathological examination showed a typical Warthin tumor appearance, with bone formation in the hyalinized structure of the tumor. At present, the patient has no evidence of disease.

We recently encountered a rare case of desmoplastic fibroma occurring in the right side of the maxilla with osseous lesions of the left shoulder, left forehand, and neck. A 47-year-old woman was referred to us for painless swelling of the right side of the maxilla. On intraoral examination, the swelling was firm, nontender, and had a sessile base and a smooth surface. Computed tomography revealed a soft tissue mass at the right side of the maxilla, measuring 28×35×40mm, which showed poorly defined radiolucency and a welldemarcated margin. The tumor had elevated the right sinus floor, and spread into the right pterygomaxillary fissure, with oppressive erosion to the right ramus of mandible. At the neck region, right shoulder, and right forearm, there was radiographic evidence of cottonlike and solid osteopetrosis. Wide resection of the maxilla, including the surrounding tissues, was performed under general anesthesia. At the present, the patient's progress is good.

We recently experienced a rare case of bilateral (multiple) sialolithiasis of the submandibular gland. A 79-year-old female was referred to us for extraction of the first molar in the right mandible. While she had slight swelling in the right submandibular region, X-ray showed the presence of small calcific densities not only adjacent to the angle of the right mandible but also to that of the left. Purulent material was discharged from the right submandibular duct, but there were no symptoms in the left. Computed tomography revealed eight calculi: five calculi in the right submandibular gland, one in the right submandibular duct, and two in the left submandibular gland. After antibiotic therapy, all calculi and both of the submandibular glands were removed surgically. As of the present, the prognosis of the patient is good.
