Selective facial neurectomy for spastic disorders of the facial nerve. 1985

G J Spector

Selective facial neurectomy in combination with bilateral musculocutaneous resection, plication brow lift, upper lid blepharoplasty, and limited rhytidectomy was performed on 18 patients with essential blepharospasm, eight with hemifacial spasm, and two with CNS vascular compression malformations. Microscopy showed the nerve tissues to be normal. Initial results were excellent. At 3 months there was a slight, persistent spastic twitching of the affected muscles in five nerves (a 14% failure rate in correcting blepharospasm). After 13 months there were four additional failures resulting from nerve regrowth in three and from one patient not completing therapy. The overall blepharospasm failure rate was 26%. On repeat neurectomy those with nerve regrowth presented with a diffuse, fine meshwork of nerve fibers reinnervating the mimetic facial musculature. In six of seven patients operated on again, spasticity was eliminated. The initial surgical failure rate has been corrected by resecting the frontal branch and the superior division of the buccal branch of the facial nerve. Only repeat neurectomy can correct long-term failures resulting from facial nerve regrowth.

D005154 Facial Nerve The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and SALIVARY GLANDS, and convey afferent information for TASTE from the anterior two-thirds of the TONGUE and for TOUCH from the EXTERNAL EAR.

D005155 Facial Nerve Diseases Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle. The nerve may be involved intracranially, along its course through the petrous portion of the temporal bone, or along its extracranial course. Clinical manifestations include facial muscle weakness, loss of taste from the anterior tongue, hyperacusis, and decreased lacrimation.
