Abstract：Objective To investigate the clinical effect and functional advantages of latissimus dorsi myocutaneous flap in repair-ing severe soft tissue defects after oral cancer surgery.Methods From April 2024 to April 2025,9 patients with stage T3-T4 oral cancer were treated.Radical neck dissection combined with extended tumor resection was performed,and free latissimus dorsi myocutaneous flaps were used to repair the remaining defects(6 cm × 9 cm to 8 cm × 16 cm).Postoperative follow-up was conducted for 3 to 6 month to elalu-ate the clinical outomes.Results The latissimus dorsi myocutaneous flaps survived in all 9 patients,the donor sites were closed and healed well,and there was no obvious limitation of mouth opening after operation.Conclusion Latissimus dorsi myocutaneous flap is an ideal choice for reconstruction of severe soft tissue defects after oral cancer surgery because of its large tissue mass,reliable blood supply,simple preparation and good morphological and functional reconstruction effect.
