Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) in Thyroiditis

Parenchymal fibrosis, which develops in the case of thyroiditis, makes thyroidectomy difficult and increases complication rates. Similar concerns exist within minimally invasive thyroid surgery. This study aimed to evaluate the outcomes of the transoral endoscopic thyroidectomy vestibular approach (TOETVA) procedure in patients with thyroiditis.

The data of 56 patients who underwent TOETVA between February 2018 and March 2020 were analyzed retrospectively. The patients were classified as those who had lymphocytic or Hashimoto thyroiditis (group T) and those who did not (group NT) in the postoperative pathology results. Results were evaluated in terms of intraoperative, postoperative findings, and complications.

All patients were female individuals with a median age of 43 (21-76). There were 21 (37%) patients in group T and 35 (63%) patients in group NT. Mean operation times were 174.2±37.4 and 201.4±45.6 minutes in groups T and NT (P=0.025), respectively, and were statistically shorter in group T. Blood loss was 37.9±44.5 and 34.6±46.8 mL (P=0.811) in groups T and NT, respectively. Transient recurrent laryngeal nerve palsy occurred in 1 patient (5%) in group T, 1 (3%) in group NT (P=0.712), and transient hypoparathyroidism occurred in 3 patients (14%) in group T and in 7 (20%) in group NT. There was no difference in terms of intraoperative and postoperative complications.

Although thyroiditis is a condition that complicates thyroidectomy, TOETVA can be applied with similar complication rates in patients with thyroiditis.
