Abstract
Objectives To describe a retrosigmoid craniectomy, hearing-preservation approach for resection
of vestibular schwannoma.
Design/Setting/Participants A video of a single patient undergoing the above approach at a tertiary care skull
base surgery program.
Results 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.
Conclusion A retrosigmoid craniectomy approach for vestibular schwannoma offers a potentially
hearing preservation approach for selected tumors.
