Masseteric nerve for gracilis muscle re-innervation in unilateral facial palsy: Impact on quality of life

Facial animation with gracilis muscle transplant re-innervated with masseteric nerve is a safe and reliable procedure in selected unilateral facial palsy patients. Results reported here confirm that surgery mainly improves the functional aspects of a patient's daily life quality, while the impact on social interactions and self-perception is less significant. The comparison of these results with those obtained in patients treated with gracilis muscle transplant re-innervated via contralateral facial nerve suggests that spontaneity is probably highly relevant to improve social aspects of QOL in this subset of patients.
