    Author: Ding S, Shi L, Ding Y.
    Journal: Lin Chuang Er Bi Yan Hou Ke Za Zhi; 2003 Jan; 17(1):20-1. PubMed ID: 12725181.
    Abstract:
    OBJECTIVE: To explore the clinic characteristic of petrous bone cholesteatoma. METHOD: One case was treated by supra-labyrinth approach. 8 cases did by labyrinth-cochlea approach. RESULT: After 2 to 9 years follow-up in the 8 cases, no local cholesteatoma relapsion occurred. 2 cases were treated by facial nerve decompression and facial paralysis did not recover postoperatively. 1 case suffered from facial muscle movement 2 months after operation and recovered after 7 months later. 1 case still needs further follow-up with 2 months postoperatively. CONCLUSION: Proper surgical approach should be selected according to location and invasion of disease. Packing with adipose tissue and blocking the external auditory meatus are effective methods to prevent the cerebrospinal fluid leak.
