Abstract

Objective To discuss the surgical method and clinical effect of applying the facial artery perforator-based nasolabial para-nasal advanced flap to repair the medial canthus and inner lower eyelid skin defects. Methods The advance nasolabial para-nasal perforator flap supplied by facial artery, was used to repair the medial canthus and inner lower eyelid skin defects, caused by dermatoma excision.
