Motor and sensory rehabilitation of the lower lip

摘要

The lower lip serves pivotal functional and aesthetic roles in the face. Palsy of lower lip musculature may result in oral incompetence, articulation difficulties, and impairment of facial expression. Loss of lower lip sensation may result in unrecognized trauma, sialorrhea, and social embarrassment. Herein, we review therapeutic approaches to lower lip réanimation and sensory neurotization.
