Functional outcomes assessment following free muscle transfer for dynamic reconstruction of facial paralysis: A literature review

Facial reanimation provides patients affected by chronic facial paralysis a chance to regain basic human functions such as emotional expression, verbal communication, and oral competence for eating and swallowing, but there is still no consensus as to the best way to measure surgical outcomes. We performed a literature review to investigate the different functional outcomes that surgeons use to evaluate facial function after reanimation surgery, focusing on outcomes other than facial expressions such as speech, oral competence, and patient quality of life/satisfaction. A total of 37 articles were reviewed, with the majority reporting outcomes through subjective facial expression ratings and only 15 dealing with other functional outcomes. In particular, outcomes related to oral competence and speech were reported inconsistently. Facial reanimation patients would benefit from a unified movement to create and validate through consensus, an outcomes reporting system incorporating not only facial expression, but also oral competence, speech, and patient-reported quality of life, to enable global patient assessment.
