Smiling is a fundamental component of social interactions.

Significant challenges arise for patients with facial palsy.

One of the key procedures for dynamic smile restoration is the microneurovascular transfer of a gracilis muscle.

We aimed to assess the effectiveness and safety of dynamic smile reanimation surgery using the free gracilis muscle unit in patients with facial palsy.

We conducted a systematic review and meta-analysis of studies reporting surgical outcomes of dynamic smile restoration using free gracilis muscles identified from EMBASE, Medline, and Web of Science databases from their inception to March 15, 2018.

Two-stage screening and data extraction were performed by two independent reviewers. Pooled proportions were calculated using random-effects models.
