Evaluation of voice function after BABA robotic thyroid lobectomy: A comparative analysis with endoscopic thyroid lobectomy

The purpose of this study was to compare the effect of robotic thyroid lobectomy via Bilateral Axlio-Breast Approach (BABA) and endoscopic thyroid lobectomy on the voice function. A total of 125 patients with thyroid cancer from March 2021 to July 2022 were divided into the robotic thyroid lobectomy group and the endoscopic thyroid lobectomy group. Acoustic index and voice handicap index (VHI-10) were compared between the 2 groups before and after (1 week, 1 month, 3 month) the surgery. In the robotic group, VHI-10 score was not significantly different before and after the surgery. In the endoscopic group, VHI-10 score after the surgery was significantly higher than that before the surgery. In the endoscopic group, the fundamental frequency (F0) declined significantly 1 week and 1 month after the surgery compared with that before the surgery. One week after surgery, F0 in the endoscopic group was (197.91 ± 24.15) Hz, which was significantly lower than that (206.77 ± 20.13) Hz in the robotic group. In the robotic group, there was no obvious decline in F0 and MPT in each follow-up period after surgery compared with those before surgery. In the endoscopic group, MPT declined significantly 1 week after the surgery compared with that before surgery. One week after surgery, MPT in the endoscopic group was (13.02 ± 9.28) s, which was significantly lower than that (17.55 ± 9.25) s in the robotic groups. There were no significant differences in Shimmer, Jitter, DSI and NHR during all postoperative follow-up periods compared with those before surgery in both groups. The voice function of robotic thyroid lobectomy via BABA is superior to endoscopic thyroid lobectomy.
