CONCLUSIONS
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.
