A Clinical Study of Ameloblastoma in Our Department

We studied 18 patients with ameloblastoma who visited and were treated in our department from September 2002 to August 2010. The patients were 11 males and 7 females, aged 14 to 74 years(median, 34.7 years).The percentage of the patients under 40 years of age was 72.2%. Tumor occurred in mandible on 16 cases and in maxilla on 2 cases. Histopathologically, solid / multicystic type was observed in 15 cases, unicystic type in 2 cases, desmoplastic type in 1 case. We performed extirpation on 14 cases and dissection of the jaw on 4 cases. When we performed extirpation, we added the procedure of peripheral osteotomy and cryotherapy. Two of 14 patients(14.3%)who underwent extirpation had a recurrence, but we performed re-extirpation and the lesions can be controlled. These results suggested that the treatment policy in our department for ameloblastoma is appropriate.
