Abstract:
Objective:To discuss the application of free double-layered auriclar composite tissue flap (auriclar cartilage and the skin) in repairing the full-thickness nasal alar defects.Methods:The clinical data of the patients with unilateral full-thickness nasal alar defects who were admitted to the Department of Plastic Surgery of Sichuan Provincial People’s Hospital from June 2016 to December 2019 were analyzed. The free double-layered auricular composite grafts were harvested from the unilateral nasal cavity as the nasal lining and covered with pedicled skin flap. The survival of free double-layered auricular composite grafts and pedicled skin flap as well as the appearance of the reconstructed nasal alar were observed.Results:A total of 12 patients with unilateral full-thickness alar defect were included, including 4 females and 8 males, aged from 6 to 53 years old, with an average of 35.3 years old. The areas of the defects were 0.7 cm × 1.0 cm-2.0 cm × 2.6 cm, and the areas of double-layered auricular composite grafts(skin) were 0.8 cm × 1.0 cm-2.1 cm × 2.7 cm. All the 12 patients healed primarily. No necrosis or infection occurred in the double auricle composite tissue flap and pedicled skin flap. After the completion of the whole treatment, the reconstructed nasal alar with similar shape and function to the normal nasal alar was obtained. After the last operation, the patients were followed up for 3 months to 32 months, with an average of 15 months.Conclusions:The free double-layered auricular composite grafts breaks the area limitation of free transplantation of full-layer auricle composite tissue flap. The combined grafting with pedicled flap shortens the treatment duration with skin flap alone, and it is easier to obtain vivid nasal alar.
