Nerve sources for facial reanimation with muscle transplant in patients with unilateral facial palsy: clinical analysis of 3 techniques.

摘要: Ninety-one patients with long-standing unilateral facial palsy and submitted to reanimation of the face muscle transplant were divided into 3 nonrandomized groups: group I: 2-stage reanimation, cross followed by gracilis transplant, 58 patients; II: 1-stage latissimus dorsi 11 (a branch nerve on nonparalyzed side was used as source for in groups I II); III: neural coaptation respective ipsilateral masseteric trigeminal nerve, 22 patients. No microvascular complications observed. The average interval between surgery initial contractions 11.1 months, 7.2 3.7 months I, II, III, respectively. quality (intensity shape) smile, voluntary or involuntary, obtained reanimated relation unaffected considered good excellent 53.4%, 54.5%, 86.3% In age results (19.8 + 10.5 years) significantly lower than that fair poor absence movement (36.5 13.3 years). smile emotional involuntary 34% 45% II. Most each only able produce "voluntary smiles". Crossed synkinesis lip puckering observed 48% 90% more uniform predictable those other techniques evaluated this study.
