73 year old male with mucoepidermoid carcinoma invading left facial nerve. Mild pre-operative facial weakness. Resection, clean proximal margin at stylomastoid foramen, clean distal margins at upper and lower divisions. Cable grafted with tension and suboptimal exposure of the proximal stump (entering foramen but wanted to avoid doing mastoidectomy), using great auricular nerve graft. Full course radiation postoperatively. At 11 months, no clinical movement.
Is re-grafting from temporal bone to distal stumps with no tension, using fresh, slightly longer grafts from sural nerve worth trying? Other testing?
