Clinical Outcomes of Thoracodorsal Artery Flap in Oral and Maxillofacial Reconstruction

The goal of this study is to retrospectively compare different types of free flaps to determine the most suitable free flap for functional reconstruction in oral squamous cell carcinoma patients following tumor resection. The main questions it aims to answer are: Do the clinical characteristics of the thoracodorsal artery perforator flap differ from those of other types of flaps? Does the thoracodorsal artery perforator flap result in better clinical outcomes compared to other types of flaps? After reconstruction with the thoracodorsal artery perforator flap, do patients have better quality of life, speech function and scar healing compared to other types of flaps? Investigators will retrospectively compare the thoracodorsal artery perforator flap with other types of flaps (such as the anterolateral thigh flap, forearm flap, latissimus dorsi flap and fibula flap) to explore the most suitable free flap for facial defect reconstruction in oral squamous cell carcinoma patients. Participants are oral squamous cell carcinoma patients who previously underwent facial defect reconstruction with different types of flaps. Participants have completed relevant questionnaires at 1, 3, 6 and 12 months post-surgery. The data will be scored and assessed by the investigators.
