Bidirectional/double fascia grafting for simple and semi-dynamic reconstruction of lower lip deformity in facial paralysis

摘要

Background: For the total aesthetic reconstruction of facial paralysis, treatment of lower lip deformity as "a neglected target in facial reanimation" is important. Although various dynamic reconstruction approaches have been reported for lower lip deformity, these have not been popularly performed due to aggressive surgical invasiveness, long recovery time for reinnervation, and unstable outcomes. To reconstruct the lower lip deformity more simply but semi-dynamically, we modified bidirectional/double fascia grafting methods that have been established as simple and minimally invasive treatments for pediatric congenital lower lip paralysis.
