Nerve-Preserving Endoscopically Assisted Resection of Schwannoma of the Radial Nerve.

Schwannomas are the most common peripheral nerve tumors; they can present as painful masses or paresthesia. The aim of surgical treatment of a symptomatic schwannoma is total to gross total excision of the tumor along with preservation of the affected nerve and its function, particularly in patients with conserved functionality of a major nerve trunk. This Technical Note describes the technical details of nerve-preserving endoscopically assisted resection of a schwannoma of the radial nerve. This is an intracapsular resection of the tumor, and the risk of nerve injury is minimized.
