作者对1971～1986年间手术治疗的125例(127耳)小儿中耳乳突胆脂瘤的效果进行回顾性分析。术式选择主要根据病变范围、乳突大小和气化程度以及咽鼓管的机能状态而定。对局限于中耳腔的小胆脂瘤特别是先天性胆脂瘤可行耳道内径路鼓室探查术。本文有17.2%的患者采用此术式。对病变较广,侵及鼓窦和乳突腔者则行封闭式乳突根治+鼓室成形术。本文有39例(30.5%)采用后鼓室进路保留外耳道后骨壁的所谓穿越耳道壁的乳突凿开术(a ca-nal wall up mastoidectomy),其中10例是经
The authors retrospectively reviewed the efficacy of 125 cases (127 ears) of pediatric middle-ear mastoid cholesteatoma treated surgically from 1971 to 1986. The choice of surgical procedure depends primarily on the extent of the lesion, the size and degree of gasification in the mastoid, and the functional status of the eustachian tube. Right limited to the middle ear cavity of small cholesteatoma, especially congenital cholesteatoma feasible canal ear canal tympanometry. 17.2% of patients in this article use this technique. On the more extensive lesions, invasion of the sinuses and mastoid cavity are closed mastoidectomy + tympanoplasty. In this study, 39 cases (30.5%) of the cavernous wall up mastoidectomy using the posterior tympanic approach retained the external auditory meatus wall, of which 10 were
