Lipoma may occur is any part of the body where fat is existing, but is rarely found in the oral cavity. Among various lipomas, those related to the proliferation of adipose and fibrous tissues are designated as fibrolipoma.A 76 year old man was referred to our department with a main compliant of swelling of the lower right second molar mucosa, which was first noticed about four years ago and gradually increased in size thereafter. Family and past histories showed no specific problems. Oral examination revealed that a pediculated elastic soft phyma was covered by the oral mucous membrane at 7 portion. X-ray examination showed however no anomalies and laboratory findings were all within normal ranges. The clinical diagnosis of right mandibular benigh tumor finally made (Epulis).On January 19, 1983, the tumor was enucleated under local anesthesia, which was easily removed en bloc by incising its surrounding mucosa and performing a blunt decollement. The prognosis is favorable with no sign of relapse as of 10 months lapsed after operation. Thus removed tumor was 2.4×1.7×1.2cm in size, elastic-soft and massive in nature, of which cut surface was yellowish white. From the histological examination, the diagnosis of fibrolipoma was made based on the facts that the surface was covered by stratified squamous cells and that many matured adipose tissues were observed below the mucous membrane with porliferated fibrous connective tissue in part.
Restriction of mandibular movement is one of the main reasons for seeing a dentist. In this article, two patients were reported in whom torus-like morphological changes at posterior aspect of articular eminence of temporal bone considered to be playing the main role in the trismus, and the anatomical bases influencing the mandibular movement especially the translation of mandibular condyle was briefly reviewed.
Angiomyoma is frequently found in the skin and subcutaneous tissues, especially in the lower extremities, but it is rarely found in the oral cavity. A case of angiomyoma of the hard palatal region is here presented.A 42 year old housewife was referred by a dental clinic for swelling of the hard palate. She had been unconscious of this swelling until it was pointed out. Past and family histories were negative. Clinically, the tumor presented a painless well-defined, smooth, soft, compressible, submucosal swelling overlying the middle of the hard palate slightly to the left of the midline. The mucosal color was blue-purple. The clinical impression was hemangioma. In October, 14, 1982, the patient was given local anesthesia and an incision was made in the palatal mucosa along the circumference of the tumor. The tumor was easily removed en bloc with a part of the hard palatal mucosa. A surgical pac was packed into the cavity fixed by resin splint and was removed on the seventh postoperative day. She was admitted to the hospital because of bleeding that same evening. We stopped the bleeding and she was discharged the following day. Twelve months later, she is well and free of tumor. On section, the tumor measured about 9×9×5 mm and was a smooth, lobulated, white oval nodule. Microscopically there was well-delimited nodular tumor under mucosa with a delicate incomplete capsule. The tumor consisted of convoluted thick-walled vessels surrounded by benign smooth muscle with few elastic fibers. The pathological diagnosis was angiomyoma.Angiomyoma of the hard palatal region: Report of a case
Malunion of fractures of the middle third of the face results in facial disfigurement and functional disturbance of the masticatory system. In such a case, it is necessary to correct these conditions simultaneously.In this report, the authors present a woman who suffered “dish face” deformity and Angle Class III malocclusion caused by the malunited maxillary fractures, and the surgical exprience of modified Le Fort III (malar maxillary advancement) + Le Fort I osteotomy.
Arteriovenous malformations of the jaws are considered to be rare lesions, A-14-year-old school boy was referred from a hospital for profuse bleeding after the extraction of the mandibular right first molar. Orthopantomography showed an irregular radiolucency extending from the mandibular right lateral incisor region to the right mandibular notch and dental film showed "soap bubble" appearance. In angiogram the main feeding vessels appeared to be the right facial artery, the right lingual artery, the right inferior alveolar artery, the right massteric artery and the right buccal artery. Expecially the right facial artery was as enlarged as the right external carotid artery. Embolization of the facial artery was performed to decrease the blood flow in the region of the mandibular lesion. The next day under nasoendtracheal general anesthesia, preparations were made for enucleation by the ligations of the right external carotid, right lingual and right facial arteries. The enucleation of the tumor was carried out by an intraoral approach. The beginning of the operation was followed by profuse bleeding. However, after the ligation of the right inferior alveolar artery, hemorrhage was controlled and the tumor was removed with relative ease. The postoperative course was entirely without complications. Anorthopantomography taken one year and seven months after the operation showed significant osseous regeneration in the area of the lesion. The pathological diagnosis was arteriovenous malformation.
