악골에 발생한 법랑모세포종의 임상 방사선학적 고찰

Abstract

A clinical and radiologic study of 46 intrabony ameloblastomas were undertaken from the files of the Department Oral and Maxillofacial Surgery, Dental Hospital, Yonsei University for the years January 1979 through December 1993. The results were as follows : 1. In the clinical findings, the mean age of patients was 34 years, with no sex predilection noted and the most frequent sign was swelling of the face or jaw. 2. In the radiological findings, the majority of tumors, 97.8%, involved the mandible with the posterior regions favored, and 56.5% of tile lesions were multilocular type. Radiologic types had no correlation with the age of patients. 3. In the histologic findings, 23.9% of the lesions were follicular or mixed type. Histologic types had no correlation with the radiologic types, but a correlation between the unicystic type and first decade of age was found by X2 test(P<0.05). 4. Among the qualified 18 patients treated with radical or conservative surgery, the recurrence rate was 33.3%. The difference of recurrent rate between the multilocular type(36.4%) and the unilocular type(28.6%) was not much. Conclusively, more detailed clinical and radiologic parameters should be added to clearly predict the biologic behavior of ameloblastoma.
