摘要

To compare postoperative outcomes of Pectoralis Major Myocutaneous (PMMC) flap alone versus PMMC flap combined with a reconstruction plate (RP) in patients undergoing mandibular defect reconstruction following oncologic resection. A retrospective analysis was conducted on 36 male patients (aged 30–55 years; mean age: 42 ± 10 years) with Stage III or IV oral squamous cell carcinoma involving the buccal vestibule and floor of the mouth, treated between July 2021 and July 2024. All patients underwent wide local excision with segmental mandibulectomy, followed by reconstruction using either a PMMC flap alone (Group A, n = 18) or PMMC flap with a reconstruction plate (Group B, n = 18). Postoperative outcomes were evaluated over 6 months and included complications (suture dehiscence, fistula, necrosis, plate fracture/exposure), nutritional intake, speech intelligibility, and esthetic satisfaction. Data were analyzed using SPSS version 26.0, with significance set at p < 0.05. Group A reported complications including suture line separation (16.6%), orocutaneous fistula formation (22.2%), and partial flap necrosis (11.1%). In contrast, 83.33% of Group B patients retained the reconstruction plate without complication, though 5.55% experienced plate fracture. Nutritional outcomes favored Group B, with 61.11% of patients achieving normal oral intake compared to 50% in Group (A) Esthetic and functional outcomes were generally superior in Group (B) The combination of a PMMC flap with a reconstruction plate provides a practical and effective alternative for mandibular reconstruction in patients with medical or financial limitations. It offers favorable functional outcomes with fewer complications and reduced operative time. Further studies are needed to validate these findings across broader populations.
