The osteoporosis is a disease that represents a reduction in the volume of bony tissue relative to whole bone volume. And mandible also may be affected. Such porotic mandible may influence the result of the surgery like dental implant surgery relating mandible. So, the author examed the panoramic view of 89 persons for finding the possibility of useful diagnostic parameters of osteoporosis. To know the correlationship between the condition of vertebra and mandible, bone marrow density of lumbar spine from 2nd to 4th, and the number of residual tooth, panoramic mandibular index (PMI), angular cortical bone thickness (ACT) and ramus cortical bone thickness (RCT) were compared. The result is that PMI and ACT have similar relative weak linear correlationship, RCT have very weak linear correlationship, the number of residual tooth have not linear correlationship.

Neurilemmoma is a bemgn tumor of nerve sheath origin, apparently derived from the Schwann cells, which may arise from any myelinated nerve fiber Although it is a relatively common tumor, it is rarely seen in the oral cavity. Actually the greatest majority of oral neurilemmomas have been reported in tongue and cheek, and most of them have been in small size. The following case is reported because of the large tumor size and its unusual location in the area of submandibular gland. It seems to arise from the mylohyoid nerve of the fifth cranial nerve. A 35-year-old man came to the department of oral and maxillofacial surgery of Kyung-pook University Hospital in October, 1994, for treatment of an egg-sized mass in the left submandibular area which had been noticed 7 months before The mass was excised under general anesthesia, and the postoperative course was uneventful. The gross specimen was ovoid, measuring 38×18×15mm, and well encapsulated with thin fibrous capsule. Histopathological finding indicated neurilemmoma composed of Antoni type A and type B tissue.

When the bone graft is perpormed after the resection of the maxilla, the grafts are usually exposed to the antral cavity. This lead to postponed re-modelling and a higher rate of resorption & sequestration. To avoid exposure of the grafts, nasal mucoperiosteal flap is rotated into the floor of maxillary sinus and lined the bone grafts. The nasal mucoperiosteal flap not only contributes to a better integration of the bone grafts but also enables the restoration of normal phyiologic function of the maxillary sinus.

The purpose of this study was to evaluate the administration period of the prophylactic antibiotic and anti-inflammatory drug used to reduce postoperative infection and edema, as compared with normal tissue healing period after operation. Author selected the 98 patients who had been performed maxillofacial bone fracture surgery, orthognathic surgery, sort tissue surgery, removal of miniplate and screw, and cyst operation, among 159 patients admitted to the department of oral and maxillofacial surgery of the one general hospital in Daegu city, during 6 months from January to June 1996. The results was slightly long administration for antibiotics and anti-inflammatory agents, as compared with physiologic healing process after surgery. Conclusively, the author propose that prophylactic antibiotics administration should be limited within 3 to 7 days after operation, and 3 to 5 days for anti-inflammatory drugs.

The 44 years old man was consulted to our department due to restriction of mouth opening. On radiograph, we found bony expansive lesion at right mandibular ramus and temporal bone that it was suspected malignant tumor. So we had performed incisional bone biopsy at right ramus through skin incision. The result of biopsy was osteosarcoma. Then, he had experienced radiation therapy for the protection of recurrence after several times surgery of nasopharyngeal angiofibroma, 28 years ago. So, we concluded radiation induced osteosarcoma from his radiation therapy history. He had referred to the department of hematooncology because of severe expansion to skull base and was received 4 times chemotherapy with cisplatin and adriamycin, but he was expired just after 4th chemotherapy. Such radiation induced osteosarcoma have relative good prognosis due to rare metastasis from other reports. So if it will early detect from close follow up after radiation therapy, survival rate will rise up. But we missed early detection of our case. So, we report a case of rare radiation induced osteosarcoma. Ly detection of our case.

This is a case report of adenoid cystic carcinoma on the right maxillary antrum and infratemporal space. The treatment of adenoid cystic carcinoma is chiefly surgical, although in some case surgery has been successfully coupled with radiation. The patient, aged 52 female, developed a pain involving the right side of face was diagnosed adenoid cystic carcinoma and treated with right tootal maxillectomy, preserving the inferior orbital rim of the right orbit, radical neck dissection performed and postoperative radiation therapy. No recurrence has been observed for 3.9 years. We will examine. Periodically the patient because of its poor prognosis and high recurrence during long term.

The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and high incidence of recurrence. TMJ ankylosis has been treated by excision and total joint reconstruction with alloplastic, allogeneic, autogenous materials as interpositional materials. The temporalis myofascial flap had been considered to be a successful interpositional material, due to its anatomical, topographical, and functional properties. This study evaluated the efficacy of the temporalis myofascial flap for nine TMJs (five patients) through the preauricular approach and coronoidectomy. Radiographic and physiologic long term result was investigated in this study. The result reveals that the temporalis myofascial flap is a good autogenous tissue satisfying the criteria of an ideal interpositional material, which offers a material that fulfills the physiological function of the disc. In spite of favorable functional outcome, mild postoperative openbite tendency remains another challenge.

The author studied on the 197 cases of the pleomorphic adenoma which had been diagnosed with biopsy during the period of 1985 to 1996 at the Kyungpook National University Hospital. This study contains the statistical analysis of the clinico-pathological findings such as sex, age, location, chief complaint, duration, treatment method, size, recurrence, and treatment department in relation to anatomical location. The result were as follows : 1. The treatment department in oxter were ENT(16.2%), GS(22.8%), OMFS(18.8%), PS(12.2%). 2. The incidence of pleomorphic adenoma were parotid gland(57.8%), palatal salivary gland(20.3%), submandibular gland(17.2%), other minor salivary glands(4.5%). 3. The tumors were more common in females than males, with a male to female ratio of 1 : 1.85. 4. The peak age of ocurrence was in the forth decade. 5. The duration of the most cases were less than 5 years. 6. Although the size of the tumors was variable, the incidence was highest between 3cm and 4cm(25.4%). 7. The most prevalent chief complaint was swelling(94.9%). 8. Conservative treatment was performed 30.0%, and radical treatment was employed 70.0%. 9. The recurrence rate is 8.1%, and recurrence used to be relatively common with conservative treatment. 10. The rate of malignant transformation is 1%. 11. The anatomical location has no relationship with the factors of sex, duration, and malignant transformation. 12. There was statistical significance on the anatomical location to the treatment department, age, chief complaint, size, treatment method, recurrence (P<0.05).
