TZ-Transposition Flap: An Alternate Method of Lower Lip Reconstruction for Partial Thickness Defects

Purpose: This study examined the reliability and cosmetic outcome of a Z-transposition flap with mucosal advancement for repairing partial thickness defects of the lower lip measuring less than 50% the lower lip length. Materials and Methods: Eleven patients treated in 2003 and 2004 were prospectively evaluated. All patients had undergone Moh's tumor excision and were referred for reconstruction. All defects measured less than 50% the lower lip length. Wound healing problems, cosmetic outcome, and flap reliability were evaluated at greater than 3 months postoperatively. Results: All patients healed uneventfully with good cosmetic results and flap reliability. Conclusions: The Z-transposition flap is an acceptable alternative for reconstructing partial thickness defects of the lower lip.
