An hourglass or funnel-shaped, stenosed, external auditory meatus with a normal tympanic membrane, middle and inner ear is one of the congenital anomalies that occasionally occurs. Such abnormality was present in both ears of a woman and caused chromic otitis externa and deafness. A routine meatoplasty on the right ear failed because of an unusual cephalad position of the drumhead in relation to a "downhill" position of the stenosed outer meatus. Rerouting the ear canal to a horizontal position by removing bone of the canal superiorly, posteriorly, and inferiorly, and grafting the now horizontal canal with skin taken from the postauricular fold produced a good result. This is a satisfactory procedure for a woman, but would be cosmetically unacceptable for a man.
一名女性双耳出现先天性异常,表现为沙漏形或漏斗形、狭窄的外耳道,鼓膜、中耳和内耳正常。这种异常导致了慢性外耳道炎和耳聋。由于鼓膜相对于狭窄外耳道的“下坡”位置处于异常的头侧位置,右侧耳朵的常规外耳道成形术失败。通过从外耳道的上、后和下方去除骨质,将耳道重新定位到水平位置,并使用取自耳后皱襞的皮肤移植到现在呈水平状的耳道,取得了良好效果。这对女性来说是一种令人满意的手术,但对男性来说在美容方面是不可接受的。
