Summary
Staged resection for huge vestibular schwannomas (VS) is challenging. Surgery may be suspended due to intraoperative difficulties, often requiring multiple operations and resulting in complications, including facial nerve damage.
Area of Science:
- Neurosurgery
- Otolaryngology
- Oncology
Background:
- Vestibular schwannomas (VS) are tumors arising from the vestibulocochlear nerve.
- Large or huge VS present significant surgical challenges.
- Staged resection is a potential approach for managing complex VS cases.
Purpose of the Study:
- To review the outcomes of nine patients with huge vestibular schwannomas (VS) treated with a staged resection approach.
- To evaluate the feasibility and complications associated with staged VS resection.
Main Methods:
- Retrospective case review of nine patients with huge VS treated between 1984-2012.
- Staged surgical resection was employed, with the decision for staging made intraoperatively due to unforeseen difficulties.
- Analysis of tumor size, number of surgical stages, and patient outcomes.
Main Results:
- Huge VS (mean size 4.7 cm) represented 0.3% of all VS surgeries.
- A total of 20 operations were performed across nine patients, with two requiring three surgical stages.
- Complete tumor removal was achieved in six of nine patients; facial nerve preservation was not achieved anatomically.
Conclusions:
- Surgery is the primary treatment for large vestibular schwannomas (VS).
- Intraoperative challenges may necessitate staged resection, potentially involving multiple procedures.
- Staged resection for huge VS is associated with significant complications, including incomplete removal and poor facial nerve outcomes.
