Reconstruction of Full-Thickness Nasal Alar Defects Using Cartilage-Supported Nonfolded Nasolabial Flaps

The difficulties faced in the reconstruction of the nasal alar defects are still continuing because of their unique anatomy, free margin, and triple-layered complex structure. In this study, we would like to present the results of the cartilage-supported nonfolded nasolabial flap reconstruction method that we applied to full-thickness alar defects involving the alar rim. Between March 2009 and October 2011, 5 patients with full-thickness alar defects underwent cartilage graft-supported nasolabial flap reconstructions. Three of the patients were men, whereas 2 patients were women. Their median age was 54.2 years (range, 43-62 y). The defects were caused by either tumor excision or trauma. According to the method we applied, cartilage grafts were placed into the pouches formed between the skin and the adipose tissue to provide cartilaginous support to the nasolabial flaps to be adapted to the defect areas. The deep surfaces that were going to form the nasal mucosa were grafted using postauricular full-thickness skin grafts. Patients were followed up for a median period of 7.3 months (range, 3-21 mo). In all patients, the flaps fully fitted the defect areas and provided enough coverage over the defects. Although minimal graft contractions were observed in the later phase because of the cartilage support placed within the pouches formed in the flaps, no nasal airway constrictions were observed. The technique we applied is a simple and reliable method providing adequate framework support, full color and texture harmony, an open nasal passage, and a single-session reconstruction in most cases.
