  • The authors evaluated the distribution of the antral pathologic conditions and their radiographic features on the Waters' radiolgraphs of 151 children patients who had been radiographed at the department of Oral Radiology, Seoul National University Hospitals. The obtained results were as follows: 1. The most common pathologic condition was inflammatory change(58%). Percentage of cases showing cystic lesion and fibro-osseous lesion were 25% and 11% respectively. 2. In cases of inflammatory change, odontogenic origins were 12 cases(13%) and bilateral occurrences were 37 cases(39%). 3. The most common radiographic feature of the inflammatory conditions was various types of mucosal thickenkng(78%).Percentage of cases showing totally increased radiopacity was 18%. 4. Intrinsic cystic lesions were 26 cases(65%) and dentigerous cyst was the most common extrinsic cyst. 5. Most of the fibro-osseous lesions(15 from 17 cases) were fibrous dysplasia. 6. Maxillary sinus hypoplasia(5 cases) and Burkitt's lyphoma(4 cases) were also observed.

  • A choristoma is a tumor like mass of normal tissue in an abnormal location. Lingual osseous choristoma, previously known as osteoma of the tongue base, is rare entity. That is defined as a normal bone mass occuring in the soft tissue of either the skin or the mucosa of oral cavity. The cause of osseous choristoma of the tongue is still unknown, but only several theories have been suggested. Because of the rarity of this entity, our purpose is to add our case to the literature, and to discuss the nature of the disease.

  • Osseous bridging between lumbar transverse processes is an uncommon condition that may cause low back pain. In most cases, its etiology is alleged to be trauma to the back and only rarely has a congenital origin been indicated. Furthermore, most reported cases involved adults, the majority of whom were middle-aged. Here, the authors describe the case of the youngest girl reported to date with congenital transverse process bridging. As far as the authors' knowledge, there has been no report of congenital bridging of transverse processes in children or adolescents in Korea.

  • Heterotopic ossification (HO) is the formation of mature bone in soft tissue where bone normally does not exist. Although HO is among the most common complications after orthopedic surgery, it is not familiar to oral and maxillofacial surgeons. Here we report rare cases of HO. When a patient presents atypical osseous lesions, HO as well as similar lesions such as osteoma, osteochondroma should be considered in the provisional diagnosis. Three-dimensional reconstruction of preoperative computerized tomography imaging improves surgical success.

  • The diagnosis of isolated tuberculosis of the brachioradialis muscle without osseous involvement was made by excision of the lesion and histologic examination in a 72-year-old woman who was in a poor general state. The patient was free of other systemic symptoms or other foci of infection. The wound healed without complication with the aid of antituberculous chemotherapy. Two years later, the patient remains symptom-free with no signs of recurrence.

  • The present study reports a case of developmental salivary gland defect. On panoramic examination, large radiolucent lesion surrounded by a sclerotic wall was noted in the right posterior mandible. On CT examination, large lingual bone concavity with extra-osseous course of the inferior alveolar nerve bundle was detected. In atypical cases, it is suggested that confirmatory imaging using CT or MRI should be taken.

  • A 22-year-old male patient had developed a submasseteric abscess secondary to a mandibular osteomyelitis at the age of 7 years old. The initial presentation at that time seems to be acute suppurative parotitis. The computed tomographic scans taken before surgery demonstrated diffuse deformity, sclerotic change and osteolytic lesion in the mandible. There was no marrow space on both sides of mandibular ramus and thin-walled cortical bone was seen. So, from the results of the computed tomography, the surgery was performed intraoral vertical ramus osteotomy (IVRO) instead of performing the more commonly used bilateral sagittal split ramus osteotomy (BSSRO). In this report, we present a case of surgical correction of mandibular prognathism with fibrous-osseous lesion of mandible with using IVRO.
