Microsurgical outcomes and complications of 62 acoustic neuromas

Objective To summarize curative effect and complications in acoustic neuroma microsurgery in order to improve postoperative 1ife quality of patients. Methods A retrospective analysis was conducted in 62 acoustic neuroma patients who underwent microsurgical treatment through suboccipital retrosigmoid approach between January 2009 and January2014. Results 53 tumors were total removed; 7 tumors were subtotal removed; and 2 tumors were partially removed. Anatomic facial nerve preservation was achieved in 56 cases and functional facial nerve was preserved in 40 cases. Post- operative complications included aggravated lower cranial nerve symptoms in 3 cases,CSF 1eakage in 4 cases and meningitis in3 cases. No surgical death was observed. Conclusion Microsurgery is a safe and effective method to remove acoustic neuroma via suboccipital retrosigmoid approach. Relative techniques can be used for further improving total removal rate and decreasing complications.
