Abstract:Abstract Objective To evaluate the clinical utility of the combined breast areola and oral vestibular approach in radical resection of differentiated thyroid carcinoma (DTC), with a focus on the safety and efficacy regarding completeness of lymph node dissection, as well as protection of the parathyroid glands and recurrent laryngeal nerves. Methods A retrospective analysis was conducted on clinical data from 13 DTC patients who underwent endoscopic thyroid cancer radical resection via the combined breast areola and oral vestibular approach at Loudi Central Hospital between October 2021 and June 2024. Assessed parameters included operative time, intraoperative blood loss, number of lymph nodes dissected, postoperative complications, and cosmetic satisfaction. All data were statistically analyzed using SPSS 22.0 software. Results All surgeries were successfully completed without conversion to open surgery. The mean operative time was 251±66.7 min, mean blood loss was 19.6±11.3 mL, and mean postoperative hospital stay was 6.2±1.1 days. Adequate dissection of both central and lateral cervical lymph nodes was achieved. Transient mild complications occurred, including hypocalcemia (2 cases), hoarseness (2 cases), and chyle leakage (1 case), all of which resolved within 3 months postoperatively. Overall cosmetic satisfaction was high, and no recurrence or metastasis was observed during short-term follow-up in all patients. Conclusion The combined breast areola and oral vestibular approach demonstrates favorable safety and dissection efficacy in radical resection of DTC, with low postoperative complication rates and excellent cosmetic outcomes. It represents a promising endoscopic surgical modality worthy of broader application.
