Background: To date, no report has discussed endoscopic thyroidectomy using the oral vestibular approach (ETOVA). The objective of this study was to evaluate the feasibility, safety, efficacy, and cosmetic results of endoscopic thyroidectomy involving this surgical approach.
Methods: Twenty-four patients with benign thyroid nodules were randomized into the ETOVA (n = 12) and the endoscopic thyroidectomy by areola approach (ETAA) groups (n = 12). Therapeutic effects were assessed at follow-up by physical examination. All patients were followed to evaluate thyroid function and scar formation from endoscopic treatment.
Results: Complete resection of all the lesions was performed endoscopically, and no conversion to open surgery was needed. There was no difference between the 2 groups with respect to surgical time (60.4 vs 59.6 min), blood loss (10.8 vs 13.8 mL), postoperative hospital stay (4.9 vs 4.6 d), or cost of surgery (17.6 vs 17.4 thousand yuan). Patients who underwent the areola approach had 3 scars, 10 × 2 mm, 5 × 1 mm, and 5 × 1 mm in size, all of which were visible at the 6-month follow-up. Patients in the ETOVA group did not have any scars. Follow-up showed a significant difference (P = .019) in the satisfaction score between the ETOVA (2.33 ± 0.65) and the ETAA group (1.58 ± 0.79). Imaging showed that all patients had complete resection and no residual disease. Severe complications such as subcutaneous accumulation of blood and fluid, superior or recurrent laryngeal nerve injury, and parathyroid dysfunction were not observed.
Conclusion: ETOVA was found to be safe and feasible and did not leave any scars; however, large-scale, randomized clinical trials are necessary for confirmation.
