Purpose Of Review:
This review describes the fundamental principles and recent advances in the reconstruction of total lower lip defects to restore peri-oral aesthetic and function.
Recent Findings:
Modifications to the Abbe flap and visor flap have recently been described. Recent advances to free flap techniques have focused on dynamic restoration of lower lip sling function after reconstruction. This involves the transfer of innervated or noninnervated muscle tissue to reconstruct the lower lip to restore the sphincter function of the lips.
Summary:
The reconstructive goals for a full thickness lower lip defect are to restore a functional oral sphincter, replace mucosal and external skin, and maintain a functional size of the oral aperture. Local flap reconstruction of sub-total lower lip defects is possible, but use of local flaps for total lip reconstruction often leads to microstomia. Several static and dynamic free tissue transfer options exist for lower lip reconstruction and have been summarized in this review.
