Pectoralis minor muscle transfer for unilateral facial palsy reanimation: an experience of 35 years and 637 cases.

Abstract

Free functional muscle transfers are often the treatment of choice for facial reanimation. We describe our experience with 637 cases over a 35-year period. Data was collected prospectively on all case undergoing functional muscle transfer for unilateral facial paralysis. Results were judged by the operating surgeon and an Independent panel of four observers. 354 patients had an excellent result as judged by the surgeon. An independent panel rated patients to have a significant change pre- and post-operatively comparing their Hay's scores (p < 0.001, t-test). 27.2% of patients required revisional procedures. 13.3% of patients developed late onset tightness of the transferred muscle. Facial reanimation with functional muscle transfers is a complex procedure and provides a significant improvement for the patient to display humour and emotion.
