Surgery for Intracranial Schwannoma


Intracranial Schwannomas are benign tumours arising from the nerve sheath of cranial nerves alongside the cerebellum and brainstem. Vestibular (acoustic) schwannomas are treated by surgical removal by a minimally invasive retrosigmoid craniotomy (surgical removal of part of the bone from the skull to expose the brain) or by skull-based approach, or by radiosurgery. For tumours over 2½ cm surgical removal is mostly recommended. Trigeminal schwannomas are typically treated by surgical removal through a retrosigmoid craniotomy or other skull base approach.
