Microsurgical treatment of large and middle acoustic neurinoma

Objective This paper summarize our experience of 10 patients with large and middle acoustic tumors underwent surgery, and discuss how to improve the rate of facial nerve preserved.Method 10 cases of acoustic neurinoma treated microsurgically in our department in last 2 years were analyzed retrospectively. Results Total tumor removal was accomplished in 90% of the patients . In 90% cases the facial nerve was anatomically preserved, In 30% cases the cochlea nerve was preserved. There was not one patient died. Conclusion Microsurgical treatment is an effective measure for acoustic neurinoma . Preceive pathological anatomy and preservation method of facial nerve can improve surgical results.
