Perforation of the tympanic membrane is a frequent complication of surgery for exostoses of the external auditory canal. We report an unusual histopathological finding in a temporal bone containing external canal exostoses which suggests that some of these perforations may be unavoidable.
鼓膜穿孔是外耳道外生骨疣手术常见的并发症。我们报告了一例颞骨中含有外耳道外生骨疣的不寻常组织病理学发现，提示其中一些穿孔可能是不可避免的。
