RESUMEN
PURPOSE: The previous cadaveric studies of facial artery perforators have frequently reported high variability, and those results remain to be validated in the Colombian population. Thus, we aimed to describe the vascular anatomy of the lateral nasal artery cutaneous branches and their clinical applications using Colombian cadavers. MATERIALS AND METHODS: Nine hemifaces from six fresh cadavers were included in the study. Terminal branches of the facial artery and cutaneous perforators of the lateral nasal artery were dissected. The quality, number, and distribution of the perforators were assessed. In addition, we present results of seven clinical cases for nasal alar reconstruction. RESULTS: Cutaneous perforators were found in all hemifaces, and zone 2 was the most common location. In our clinical case series, all flaps used to reconstruct the nasal alar defects survived. There were two cases of venous congestion but no additional procedures were needed. CONCLUSIONS: Although nasal alar reconstruction continues to be a challenging plastic surgery procedure, the nasolabial propeller perforator flap is an excellent choice for such because it allows a precise skin island design, is less bulky, has a wide arc of rotation, and facilitates one-staged reconstruction without increasing the rate of complications.
