Abstract

INTRODUCTION
Ameloblastoma is a benign but locally invasive tumor with a high recurrence rate. The aim of this study was to make an easier diagnosis and treatment planning of ameloblastoma.
MATERIALS AND METHODS
From January 1993 to October 2009, 139 cases from 123 patients, who had been diagnosed with ameloblastoma through radiologic and biopsy in the department of oral and maxillofacial surgery of Kyunpook National University, were selected as the subjects in this study. According to the medical charts, 9 factors (age, gender, location, chief complaints, duration, radiographic findings, size and recurrence) concerned in deciding the treatment method and the relevance between each factor and the treatment methods were examined.(Conservative treatments were marsupialization, enucleation, curettage and lateral decortication. Radical treatments included block excision, resection and hemisection)
RESULTS
In the patients under the age of 20, 77.14% had conservative treatments, whereas 22.86% underwent radical treatments. In the patients over the age of 20, 44.23% were treated conservatively treatments, and 55.77% underwent radical treatments. For unilocular types, 28.57% had conservative treatments, whereas 71.43% had radical treatments. For the multilocular types, 66.67% underwent conservative treatments, and 33.33% had radical treatments. For the primary cases, 58.68% were treated conservatively and 41.32% had radical treatments. For the recurrent cases, 16.67% and 83.33% underwent conservative and radical treatments, respectively.
CONCLUSION
There was statistical significance in the factors affecting the treatment methods, such as age, radiographic findings and recurrence.

A) Marsupialization: Removal of the upper part of the lesion for the making of intraoral opening, B) Enucleation: Removal of a lesion by shelling it out intact, C) Curettage: Surgical scraping of the wall of a cavity within soft tissue or bone for the removal of its contents, D) Lateral decortications with reposition: Surgical curettage after lateral bony window opening following reposition, E) Block excision: Surgical removal of a tumor intact, with a rim of uninvolved bone with maintaining continuity of the inferior or posterior borders of the mandible, F) Resection: Surgical removal of a segment of the mandible or maxilla without maintaining the continuity of the bone, G) Hemisection: Surgical removal of one side of the mandible or maxilla.
