Introduction:
The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a safe alternative to thyroidectomy for thyroid goiter and provides the benefit of being scarless. However, the data on the use of TOETVA in patients with Graves disease are limited. This retrospective study compared the outcomes of Graves disease patients who underwent TOETVA versus those who underwent open thyroidectomy (OT).
Materials And Methods:
Patients with Graves disease who received TOETVA or OT for bilateral total thyroidectomy between September 2017 and October 2022 were included. Patient demographics and surgical outcomes, including operation time, blood loss, length of stay, and complications, were compared.
Results:
There were 15 patients in each group. The mean age in the TOETVA group was 35.80±8.13 years, which was significantly younger than that in the OT group, which was 51.53±14.22 years. Females predominated in both groups. The other demographic characteristics were similar in both groups. The operation time and intraoperative blood loss were also comparable. The postoperative stay and complications, including hypoparathyroidism, recurrent laryngeal nerve injury, surgical site infection, postoperative hemorrhage, and recurrence of hyperthyroidism, were not different between the 2 groups. There were 11 patients in the TOETVA group and 10 in the OT group who had thyroglobulin levels <0.1 ng/dL, indicating the completeness of total thyroidectomy in the 2 groups. There was no conversion of TOETVA to an open procedure.
Conclusions:
For carefully selected Graves patients, TOETVA offers a safe, scarless, and feasible alternative to conventional open thyroidectomy.
