Positive Group: (1) Patients who underwent radical oral cancer surgery (including tongue cancer, buccal cancer, gingival cancer, etc.) combined with flap reconstruction (such as anterolateral thigh flap, forearm flap, pectoralis major myocutaneous flap, etc.) in the Department of Oral and Maxillofacial Surgery of our hospital between June 2020 and June 2025; (2) Postoperative flap crisis (manifested as changes in flap color, decreased temperature, prolonged or absent capillary refill time, flap swelling or atrophy, etc.) occurred, and secondary surgery (such as flap exploration, partial flap resection, vascular re-anastomosis, etc.) was required after conservative treatment (e.g., warming, antispasmodics, anticoagulation, etc.) proved ineffective; (3) Complete clinical data were available, including patient demographics, preoperative examination results, surgical details, postoperative care, and follow-up records. 2. Negative Group: (1) Patients who underwent radical oral cancer surgery (including tongue cancer, buccal cancer, gingival cancer, etc.) combined with flap reconstruction (such as anterolateral thigh flap, forearm flap, pectoralis major myocutaneous flap, etc.) in the Department of Oral and Maxillofacial Surgery of our hospital between June 2020 and June 2025; (2) Complete clinical data were available, including patient demographics, preoperative examination results, surgical details, postoperative care, and follow-up records.
