牙源性腺样瘤(AOT)是少见的牙源性肿瘤,作者收集文献报道的AOT464例,加上35例新病例,共499例,用计算机进行了全面分析。分型依临床和X线表现不同分为: A.中央性(骨内),占97.2％,其中: 1.滤(?)型(含牙)占73.0％2.滤泡外型占24.7％ B.外局性(骨外),占2.8％临床和X线特点 AOT一般较小,直径1～3cm,生长缓慢.X线片上表现为周界清楚的透光阴影,滤泡型可见有牙冠包埋在其中,不易与含牙囊肿区别;滤泡外型常有牙移位;约2/3病灶内见有钙化斑点。
Auricular adenoid tumors (AOT) are rare odontogenic tumors. The authors collected 464 cases of AOT reported in the literature, plus 35 new cases, a total of 499 cases, a comprehensive analysis using a computer. The classification was divided into clinical and X-ray findings: A. Central (intraosseous), accounting for 97.2%, including: 1. Filter (?) type (including teeth) accounted for 73.0% 2. Follicle appearance 24.7% B. Out-of-hospitality (outside bone), accounting for 2.8% Clinical and X-ray features AOT is generally small, 1 to 3 cm in diameter, and grows slowly. X-rays show a clear, translucent shadow on the perimeter, and follicular type has teeth visible. The crown is embedded in it and it is difficult to distinguish it from the dentate cyst; the follicular appearance is often displaced by teeth; about 2/3 of the lesions have calcified spots.
