Retrosigmoid approach to vestibular schwannoma.

Surgical removal remains one of the key treatment modalities for vestibular schwannomas. The retrosigmoid approach is particularly favored for larger tumors located primarily in the cerebellopontine angle cistern causing significant mass effect. For smaller tumors, this approach also provides an opportunity to preserve hearing. In this chapter, we describe the retrosigmoid approach for vestibular schwannoma, highlighting some of the key surgical steps and postoperative management strategies.
