Reconstruction of Large Transmural Nasal Defects With a Nasolabial Turnover Interpolation Flap.

Background: Reconstruction of large nasal surgical defects often warrant the use of mucosal flaps to repair the inner lining. This often presents a challenge for surgical reconstruction.

Objective: To describe a unique reconstructive option for the repair of large surgical wounds that necessitate mucosal nasal lining.

Materials And Methods: This study is a retrospective review of 10 patients who underwent surgical reconstruction of large nasal and/or heminasal surgical defects following Mohs micrographic surgery. A nasolabial turnover interpolation flap was used to repair missing nasal mucosal lining, coupled with a cutaneous flap which typically involved a paramedian forehead flap. The duration of follow-up was 8 months. An aesthetic and functional surgical outcomes measure was used to assess the final repair.

Results: Favorable aesthetic outcomes were obtained in all patients and without need of revision surgery by the use of a nasolabial turnover interpolation flap.

Conclusion: The nasolabial turnover interpolation flap offers a reliable and effective method of repair for large transmural nasal surgical wounds. We typically paired this nasal lining flap with a paramedian forehead flap with reliable and aesthetic outcomes. This technique is straightforward, reproducible, and with both good aesthetic and functional outcomes.
