경이접근법으로 제거한 측두골 추체부 진주종

Abstract

To completely remove the petrous bone cholesteatoma (PBC) have been a surgical challenge for many years because of tight adhesion or invasion of the matrix into surrounding vital structures such as the labyrinth, middle and posterior cranial fossa dura, internal carotid artery, facial nerve canal or jugular bulb. The main factors influencing the surgical approach to choose are the inaccessible nature of the petrous bone, the extent of disease, the degree of facial nerve function, and the need for the prevention of cerebrospinal fluid leaks and the recurrence of the lesion. We present the case of a 55- year-old male presenting with right-sided facial palsy PBC treated by transotic approach. Facial palsy in the operated ear improved after surgery. We conclude that transotic approach is a safe and effective approach to the supralabyrinthine PBC region.
