Introduction:
Although transoral endoscopic thyroidectomy (TOETVA) is widely utilized in clinical practice, some problems and restrictions still remain. Our study compared the perioperative features and early surgical efficacy of TOETVA and a modified transoral and submental endoscopic thyroidectomy (TOaST) in early stage papillary thyroid carcinoma (PTC).
Methods:
The clinical data of PTC patients who underwent endoscopic thyroidectomy, including 42 modified TOaST patients and 114 traditional TOETVA patients, were retrospectively collected. Propensity score matching was employed to reduce patient selection bias. The perioperative features and early surgical efficacy data of two groups were compared.
Results:
The operation time of the TOaST group was significantly shorter than that of the TOETVA group (150.00 ± 35.47 min vs. 168.75 ± 44.49 min; P = 0.030). Furthermore, the TOaST group required shorter days for a normal diet (3.38 ± 0.93 days vs. 4.04 ± 1.03 days; P = 0.000) and a shorter hospital stay than the TOETVA group (5.85 ± 2.17 days vs. 6.12 ± 2.01 days; P = 0.003). There was no statistical difference in complications between the two groups, but the probability of numbness of the lower lip and chin in the TOaST group was lower than that in the TOETVA group(5.12% vs. 13.04%, P = 0.321). The symptoms of mandibular numbness and hoarseness of most patients were relieved in both groups 6 months after surgery, and no abnormalities and recurrence were found in the thyroid ultrasound. All the patients were satisfied with the appearance of their surgical incision.
Conclusion:
In early stage PTC patients, TOaST had the same surgical effectiveness as traditional TOETVA but can minimize the probability of mandibular numbness and improve the perioperative quality of life.
