{Abstract}: Importance: Cross-Facial Nerve Grafting (CFNG) for facial palsy offers potential to restore spontaneous facial expression, but specific indications and associated outcomes are limited. Updates to this technique have aided in its successful employment in select cases. This review aims to explore the context in which CFNG has been successfully utilized as a primary modality. Observations: Literature review was performed auditing all studies investigating CFNG as a primary modality, which reported outcomes. A total of 326 cases reporting outcomes for primary CFNG were included. Eye closure outcomes were 83.3% successful at ages 0-18, 77.3% successful at ages 19-40, and 57.1% successful at ages 41+. Smile outcomes were 73.7% successful at ages 0-18, 81.5% successful at ages 19-40, and 52.8% successful at ages 41+. For synkinesis, 89% of cases were considered successful; 100% successful at ages 0-18, and 78.4% successful in adults. Conclusions and Relevance: CFNG may offer return of spontaneous facial function in select cases. Higher percentages of successful outcomes are observed in younger patients, when performed in two stages, and when performed earlier from the onset of FP in cases of eye closure restoration. In the modern era, CFNG has been more commonly employed as an adjunctive procedure to other reanimation techniques.
