[The application of transcervical non-inflatable endoscopic posterior inferior sternocleidomastoid approach in thyroid surgery].

To investigate the clinical efficacy and safety of transcervical non-inflatable endoscopic thyroidectomy through the posterior inferior sternocleidomastoid approach. From December 2022 to May 2023, the clinical data of 35 patients with papillary thyroid carcinoma treated by transcervical non-inflatable endoscopic surgery via posterior inferior sternocleidomastoid approach were retrospectively analyzed. There were 14 males and 21 females, with an average age of 44.7 years. The operation time, bleeding volume, postoperative recovery, complications and follow-up were recorded. All 35 patients successfully completed the surgery, with an average operation time of 4 hours and 7 minutes, an average bleeding volume of 14 ml, and an average postoperative hospital stay of 3.5 days. There were no serious complications and no obvious neck discomfort during postoperative follow-up. Transcervical non-inflatable endoscopic thyroidectomy via posterior inferior sternocleidomastoid approach is safe and effective, with fast postoperative recovery,high appearance satisfaction and good neck comfort.
