Endoscopic resection of an infraorbital nerve schwannoma

Abstract

Schwannomas are benign tumours which originate from the chwann cells sheathing the nerves. Their usual treatment consists f a complete surgical excision. While schwannomas of the periphral nerves are relatively common, trigeminal nerve schwannomas riginating from the extracranial portion of the nerve and extendng inside the cranium are a rarity. For this precise type of tumour, he favoured way of removal is via a transcranial, infratemporal pproach [1]. In this report, we present the case of a 48 year-old man with voluminous trigeminal nerve schwannoma originating from the nfraorbital nerve that extended intracranially. It was successfully reated using an endoscopic endonasal approach.
