We present a technique which we have found useful for the management of congenital cholesteatoma extensively involving the middle ear.
A five-year-old boy was presented to our department for management of a white mass on the right tympanic membrane. This congenital cholesteatoma extensively occupied the tympanic cavity. It was removed through an extended tympanotomy approach using our modified sleeve technique. The conventional tympanotomy approach was extended by gently separating the tympanic annulus from its sulcus in a circular manner. The firm attachment of the tympanic membrane at the umbo was not severed, in order to avoid lateralisation of the tympanic membrane.
Although various operative techniques can be used, our modified sleeve tympanotomy approach provides a similarly sufficient and direct visualisation of the entire middle ear, with, theoretically, no possibility of lateralisation of the tympanic membrane and subsequent conductive hearing loss.
我们介绍一种我们发现对广泛累及中耳的先天性胆脂瘤的处理很有用的技术。
一名5岁男孩因右侧鼓膜上的白色肿物前来我科就诊。这种先天性胆脂瘤广泛占据鼓室。通过使用我们改良的袖套技术的扩大鼓室切开术方法将其切除。传统的鼓室切开术方法通过以环形方式将鼓环与其沟轻轻分离来扩大。鼓膜在鼓脐处的牢固附着未被切断,以避免鼓膜外移。
尽管可以使用各种手术技术,但我们改良的袖套鼓室切开术方法能提供对整个中耳同样充分且直接的视野,理论上不存在鼓膜外移及随后传导性听力损失的可能性。
