Retrosigmoid Craniectomy for Vestibular Schwannoma with Hearing Preservation.

To describe a retrosigmoid craniectomy, hearing-preservation approach for resection of vestibular schwannoma.  A video of a single patient undergoing the above approach at a tertiary care skull base surgery program.  This video demonstrates a retrosigmoid craniectomy approach for resection of an enlarging intracanalicular vestibular schwannoma in a patient with normal hearing. The video highlights the pertinent surgical anatomy and outlines in a step-by-step fashion the surgical steps. The patient obtained a gross total resection with preservation of hearing.  A retrosigmoid craniectomy approach for vestibular schwannoma offers a potentially hearing preservation approach for selected tumors.
