外耳道骨瘤临床分析(附28例报告)

A Clinical Analysis of Osteoma of the External Auditory Canal (A reprot of 28 cases)

目的提高临床少见的外耳道骨瘤的诊断与治疗水平。方法对1993年～2002年收治的28例外耳道骨瘤的临床资料进行回顾性分析。结果 28例外耳道骨瘤中,26例行单纯性耳内切口骨瘤摘除。2例较特殊:1例行骨瘤切除+颞肌重建外耳道后壁:1例行骨瘤切除+乳突根治。结论耳内切口适用于骨瘤限于骨性外耳道、乳突部无病变时;耳后切口适用于骨瘤范围大,接近堵塞外耳道全部或病变较复杂,同时合并胆脂瘤型中耳炎等,利于扩大手术野。
