    Abstract:
    OBJECTIVE: To explore the common complications related to acoustic neuromas and to search methods for preventing from them. METHODS: One hundred and five patients with acoustic neuromas underwent 110 operations with the retrosigmoid approach, middle cranial fossa approach and labyrinth approach. All cases were followed up more than 1 month after surgery. RESULTS: Of 110 cases, the most frequent complication was hearing disability which occurred in 95 cases (95/110, 86.4%). and the facial paralysis was in 63.6% (70/110) after one month. Other complications were cerebrospinal fluid fistulas (CSF, 12.7%, 14/110) , intracranial hematoma (5.5%, 6/110), cranial nerve palsies (4.5%, 5/110), meningitis (3.6%, 4/110), tetraparesis (3.6%, 4/110), balance disturbance (1.8%, 2/110), hemiparalysis and anepia (0.9%, 1/110). Effective stopping bleeding during operation and controlling blood pressure after operation, as well as keeping effective sedation in 24 hours after operation were the important ways to prevent from intracranial hematoma The haemorrhage often accrued in 48 hours post-operation. CSF in this series was another common complication in acoustic neuroma surgery. Ten cases with CSF subcutaneous retro-auricular had been successfully controlled by conservative treatment. Of 4 cases with rhinorrhea CSF, 3 of them were required surgical management, another one got self-cure by bed rest. The ventricular drainage pro-operation was the most important procedure for drawdown the hypsi-cranium pressure. CONCLUSIONS: The key factors to avoid the complications include mastering the anatomy of different surgical approach, how much of the tumor size, surgical experience and preoperative evaluation of patients' imaging information and other clinical data.
