Nasolabial perforator flap for nasal defects

Nasal defects can be reconstructed with a nasolabial perforator flap, resulting in good aesthetic outcomes based on the facial subunit principle, owing to the combined advantages of the traditional nasolabial flap and the perforator flap. However, the localization of perforators makes the clinical application of a nasolabial perforator flap difficult. This review aims to provide a comprehensive summary of the nasolabial perforator flap from anatomical,methodological, and clinical application aspects, intending to provide plastic surgeons with a reference on conducting nasal reconstruction with a nasolabial perforator flap.
