Surgical Treatment of Acoustic Neuromas and Its Common Complications

Objective:To study the postoperative complications and related factors of acoustic neuroma resection via suboccipital retrosigmoid approach.Methods:Thirty-six patients with acoustic neuroma were analyzed retrospectively.Results:Total removal was achieved in 28 cases,while subtotal resection was performed in 8 cases.Hearing loss occurred in 31 cases,and other complications were facial nerve dysfunction in 18 cases,lower cranial nerve injury in 4 cases,cerebrospinal fluid leakage in 3 cases,hydrocephalus or aggravated hydrocephalus in 2 cases,intracranial infection in 1 case,and intracranial bleeding in 1 cases.Only one case died.Conclusion:The high incidence of hearing loss and facial nerve dysfunction was found after acoustic neuroma resection,and the incidence of complications were related to the tumor size,cystic changes,and micro-surgical proficiency.
