A comparison of efficacy and quality of life between transoral endoscopic thyroidectomy vestibular approach (TOETVA) and endoscopic thyroidectomy axillo-breast approach (ETABA) in thyroid surgery: non-randomized clinical trial.

Abstract

Recently, there are many new surgical methods of endoscopic thyroidectomy, which have advantages in cosmetic results while do not increase the complication rates. This study was conducted to evaluate and compare both intra- and post-operative results and quality of life between TOETVA and endoscopic thyroidectomy axillo-breast approach (ETABA). A non-randomized, patient preference clinical trial was performed in Otorhinolaryngology, Head and Neck surgery department, HRH Princess Maha Chakri Sirindhorn Medical center. Patients who decided to go for endoscopic thyroidectomy were allocated into two groups. Demographics data, operative time, intra-operative blood loss, post-operative pain score, length of hospital stay, complications were collected. Overall satisfaction was evaluated by visual analogue scale and quality of life was evaluated by SF-36 questionnaires. 22 patients were totally included and equally allocated in 2 groups (11 patients per group). All of the operations were lobectomy. There was no significant difference in demographic data. The results showed that pain score at 3days post-operation and average pain score were significantly higher in TOETVA group. Average pain score was 3.67 ± 1.11 in ETABA group and 5.15 ± 1.35 in TOETVA (p = 0.011); however, the operative time, intra-operative blood loss, length of hospital stay, complications and overall satisfaction were not significantly different. Different change in the quality of life was not detected in both groups. Transoral endoscopic thyroidectomy vestibular approach and ETABA both have comparable results and do not worsen the quality of life.
