In this chapter we have reviewed the etiology, diagnosis, and surgical treatment of petrous apex cholesteatoma. The etiology is usually congenital for those tumors arising within the apex, but acquired for lesions secondarily invading the apex. Diagnosis is primarily radiographic. CT remains an excellent modality for determining the extent of disease, whereas recent advances with MRI help in differential diagnosis. In our experience the middle fossa approach and the translabyrinthine-transcochlear approach allow the surgeon the best opportunity to effectively treat this rare and challenging tumor.
在本章中，我们回顾了岩尖胆脂瘤的病因、诊断及外科治疗。对于起源于岩尖内的那些肿瘤，病因通常是先天性的，但对于继发侵犯岩尖的病变，病因则是后天性的。诊断主要依靠影像学检查。CT仍然是确定病变范围的极佳方式，而MRI的最新进展有助于鉴别诊断。根据我们的经验，中颅窝入路和经迷路-经耳蜗入路为外科医生提供了有效治疗这种罕见且具有挑战性的肿瘤的最佳机会。
