A combined nasolabial and infra-nasal bi-lobe flap design with double transposition for reconstruction of the ipsilateral upper and lower lips associated with the commissure defect

Several classical flap variations have been designed to reconstruct lip and commissure defects. Although most of these variations maybe the best option for repairing defects, there is an increasing risk of anatomic distortion and functional disability, mostly in older persons. Herein, we present a combined nasolabial and infra-nasal bi-lobe flap design with double transposition, which was used to concomitantly close the upper and lower lips associated with commissure defects.
