Abstract

Objective: Describe the outcome of translabyrinthine surgery for vestibular schwannomas (VS), with special focus on the tumor removal, postoperative facial nerve function, tumor control and complications Methods: A scoping review. Results: Out of a total of 380 articles searched on Pubmed database, the Cochrane library, the digital library Ha Noi Medical University has 15 research articles on the outcome of translabyrinthine surgery for vestibular schwannomas with 8983 patients, total removal was achieved in 82.3% (7391/8983) of cases; patients with evidence of regrowth in 2.8% (86/2986), concentrated mainly in incomplete resection tumors group. Among previously untreated patients, anatomical preservation of facial nerve was achieved in 95.94% (5046/5259) cases, and House Brackmann grade I or II was reached in 67.67% (5752/8944) patients. Facial nerve outcome depends significantly on tumor size and tumor removal. Surgical complications included cerebrospinal fluid leakage with significant incidence in 6.9% (401/5766) and others like meningitis, intracranial bleeding, and death. Conclusion: The translabyrinthine approach is safe and effective  for the removal of VS. The complication rate is very low and tumor size is still the main factor influencing outcome after surgery.
