[Endoscopic assisted parathyroid surgery via a subclavian approach].

To explore the safety and efficacy of airless endoscopic surgery in the treatment of parathyroid diseases. By retrospective comparison, clinical treatment of 26 patients with primary hyperparathyroidism admitted to the Department of Otolaryngology and Head and Neck Surgery of the Hospital, Sun Yat-sen University from January 2018 to January 2023 were collected. They were divided into traditional group（13 cases） and endoscopic group（13 cases） according to the surgical method. The traditional group underwent traditional open parathyroid surgery, and the endoscopic group underwent airless endoscopic surgery through the subclavian approach. The efficacy, postoperative incision pain, incidence of adverse events, and aesthetic effects of the two groups were evaluated. A total of 26 patients were included, including 13 patients in the traditional group and 13 patients in the endoscopic group. There was no significant difference in the incidence of hypocalcemia and transient hypoparathyroidism on the first day after surgery between the two groups（>0.05）. No patients with incision pain（>3 points） or swallowing pain were found in both groups after the operation, and they were afraid or unwilling to cough and expel phlegm. There were no significant differences in the amount of blood loss, duration of operation, incidence of temporary recurrent laryngeal nerve palsy and transient hypocalcemia, and postoperative pain score between the two groups. The endoscopic group's scar evaluation score and aesthetic effect satisfaction score at 6 months after surgery were higher than those of the traditional group（<0.01）. Airless Endoscopic parathyroid surgery via the subclavian approach has good effectiveness and safety, which did not significantly increase the risk of surgery. It can safely remove the lesion and leave no surgical scar on the anterior neck, which has the advantage of a good cosmetic effect. It is a safe and feasible endoscopic parathyroid surgery and can be used as a new choice for patients undergoing parathyroid surgery.
