Abstract: 【Abstract】 Objective To evaluate the performance of axial-pattern composite tissue flap in the repair of skin defects after lip cancer resection. Methods From July 2012 to December 2017, 8 patients with lip cancer were enrolled from Department of Dermatology, the Second Hospital of Jilin University. After lip tumor resection, the full-thickness defects were as long as 1/3 to 1/2 length of the lip, and were repaired with axial-pattern composite tissue flaps based on labial arteries. Results All the axial-pattern composite tissue flaps survived after the surgery. During the follow-up of 6 months to 5 years, no tumor recurrence was observed in the 8 patients, the shape and function of lips were improved, and the patients were satisfied. Conclusion Skin defects after lip cancer surgery can be repaired with axial-pattern composite tissue flaps based on labial arteries, which can restore the anatomical structure and aesthetic function of the lip well.
