われわれは2002年9月から2010年8月までに当科を受診し,加療を行ったエナメル上皮腫18例について検討を行った.性別は男性11例,女性7例,年齢は14歳から74歳まで平均年齢34.7歳であった.そのうち40歳未満が全体の72.2%を占めていた.部位では下顎が16例,上顎が2例であった.組織型は充実性/多嚢胞型15例,単嚢胞型2例,類腱型1例であった.治療法では摘出術を行ったものが14例,区域切除術を行ったものが4例であった.摘出術を行った場合,われわれは骨削除や凍結療法を加えた.摘出術を行った14例のうち2例(14.3%)に再発を認めたが,再度摘出術を行いコントロールできていた.これらの結果より,当科のエナメル上皮腫に対する治療方針は妥当であると思われた.

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.
