BACKGROUND: The reconstruction of full-thickness nasal tip and alar defects is challenging owing to the distal nose's triple-layer structure: skin, cartilage, and mucosa. OBJECTIVE: In the reconstruction of wounds of the distal half of the nose involving the rim, the most important issue to be considered is to provide a good functional and an acceptable esthetic result. Various local and distant flaps have been described for this purpose. The nasolabial flap is one of the most frequently used flaps in reconstruction of small- to moderate-size distal nasal defects. Its reliable blood supply, minimal donor site morbidity, and excellent texture and color match are some of the advantages of this local flap. METHODS: In this study, superiorly based subcutaneous pedicled nasolabial flaps have been prefabricated with cartilage and skin grafts. This method has been used in 10 cases. RESULTS: One patient had partial flap necrosis, and two patients experienced hyperpigmentation on the suture line. Scar revision was performed in one patient for hypertrophic scar tissue at the flap margins. No other complications were seen in the remaining patients. None of the patients experienced a skin graft loss or cartilage exposure. CONCLUSION: The prefabricated nasolabial flap offers a superior esthetic and functional result and may be an appropriate reconstructive option in reconstruction of small- to moderate-size distal nasal defects.
