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.
