Purpose: Total endoscopic thyroidectomy including oral approach and breast approach has excellent cosmetic and several functional results. Many patients, especially women, undergoing thyroid surgery are concerned about the postoperative cosmetic appearance of the neck. The procedure of total endoscopic thyroidectomy by breast approach only left three incisions, while by oral approach did not leave any incisions in the body surface, which is scarless in the neck, involved with a higher cosmetic result. However, the long-term property evaluation of total endoscopic thyroidectomy was not confirmed. The purpose of our study was to evaluate the surgical results of total endoscopic thyroidectomy (transoral approach and breast approach) versus conventional open thyroidectomy.

Purpose: Total endoscopic thyroidectomy including oral approach and breast approach has excellent cosmetic and several functional results. Many patients, especially women, undergoing thyroid surgery are concerned about the postoperative cosmetic appearance of the neck. Transoral endoscopic thyroidectomy via vestibular approach (TOETVA) and endoscopic thyroidectomy via breast approach were routinely performed in our institute. The procedures of total endoscopic thyroidectomy by breast approach only left three incisions, while by oral approach did not leave any incisions in the body surface, which is scarless in the neck, involved with a higher cosmetic result. However, the comprehensive comparison between transoral approach, breast approach and conventional open method was not confirmed. The purpose of our study was to evaluate the surgical results of total endoscopic thyroidectomy (transoral approach and breast approach) versus conventional open thyroidectomy.

Choosing to participate in a study is an important personal decision. Talk with your doctor and family members or friends about deciding to join a study. To learn more about this study, you or your doctor may contact the study research staff using the contacts about the eligibility criteria. Patients will be introduced the general information of different surgical methods, and the clinical studies.

Participants who had studied endoscopic thyroid surgeries in our department would be introduced.
