Kochhar and coinvestigators conducted a retrospective study of 20 patients with facial paralysis who underwent mobilization and transposition of the intratemporal segment of the facial nerve for an end-to-side coaptation to the hypoglossal nerve. Outcome measures include paralysis duration, facial tone, facial symmetry at rest, and with smile, oral commissure excursion, post-reanimation volitional smile, and synkinesis. They found that mobilization of the intratemporal segment of the facial nerve provided adequate length for direct end-to-end coaptation and was effective in restoring facial tone and symmetry. The resulting smile was symmetric or nearly symmetric in most patients with varying degree of dental show. The additional length provided by using the intratemporal segment of the facial nerve reduced the deficits associated with complete hypoglossal division and/or splitting, and avoided the need for interposition grafts and multiple coaptation sites.
