Abstract

Introduction: Radical surgery is considered as the cornerstone, but often results in large defects of the oral cavity, leading to severe impairment of chewing, swallowing and aesthetics. Therefore, reconstruction is essential to restore vital functions and improve the quality of life. Objectives: To evaluate the outcomes of various flap applications in reconstructing defects following oral cavity resection at Cho Ray Hospital from 2020 to 2025. Patients and methods: A descriptive cross-sectional and interventional clinical study was conducted on 83 patients with oral cavity cancer who underwent ablative surgery and immediate reconstruction at the Department of Otorhinolaryngology, Cho Ray Hospital, between 2020 and 2025. Results: Our study employed the following reconstructive flaps: 34 nasolabial flaps, 38 buccal mucosal flaps, 4 submental flaps, 1 iliac crest flap, 3 anterolateral thigh flaps, 2 fibular flaps, and 1 radial forearm flap. The flap survival rate reached 100%, with no major postoperative complications observed. The mean operative time was approximately 210 minutes, and the average hospital stay was 10 days. At 3-month follow-up, most patients had regained masticatory and swallowing functions; aesthetic outcomes were rated as good, and no local recurrence was detected. Conclusions: Flexible application of appropriate flaps—including local, regional, and free flaps—is an effective strategy for reconstructing defects after oral cavity cancer surgery. These techniques preserve essential functions, maintain aesthetic form, and improve the overall quality of life for patients.
