Abstract:
Objective:To discuss the application of free two-layered auriclar composite tissue flap (consisted of auriclar cartilage and the anterior skin) in repairing the full-thickness nasal alar defects.Methods:To analyze the clinical data of patients with unilateral full-thickness nasal alar defect admitted to the plastic surgery department of Sichuan Provincial People's Hospital from June 2016 to December 2019. One side of the concha was excised from the nasal cavity with free two-layered auricular composite grafts as the nasal lining and covered with pedicled skin flap. The survival of free two-layered auricular composite grafts, pedicled skin flap and nasal alar reconstruction 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, with an average of 35.3 years. The area of lining defect was 0.7 cm × 1.0 cm~2.0 cm × 2.6 cm, and the area of two-layered auricular composite grafts(skin) was 0.8 cm × 1.0 cm~2.1 cm × 2.7 cm. All the 12 patients healed in the first stage. No necrosis or infection occurred in the double auricle composite tissue flap and pedicled skin flap. After the completion of the whole treatment cycle, 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 12 months.Conclusions:The two-layered auricular composite grafts breaks through the area limitation of free transplantation of full-layer auricle composite tissue flap; the combined transplantation with pedicled flap shortens the treatment cycle of skin flap alone, and it is easier to obtain realistic nasal alar.
