Comparison of health-related quality of life and cosmetic outcome between traditional gasless trans-axillary endoscopic thyroidectomy and modified gasless trans-axillary endoscopic thyroidectomy for patients with papillary thyroid microcarcinoma.

Background: Gasless trans-axillary endoscopic thyroidectomy (GTET) has been proved to provide better cosmetic results; however, it has limitations as dissection of central neck lymph nodes is difficult. We developed a modified approach (MGTET-modified GTET) and compared it with the traditional one in terms of patients' health-related quality of life (HRQoL) and cosmetic results in order to provide more convincing therapeutic results.
Methods: Between January 2021 and June 2021, 100 cN0 patients who had a confirmed diagnosis of papillary thyroid microcarcinoma were randomized to undergo either MGTET (n = 50) or GTET (n = 50). These two groups' baseline characteristics, intraoperative and postoperative findings, were compared. The Patient and Observer Scar Assessment Scale (POSAS) was determined 6 months after surgery. Thyroid Cancer-Specific Quality of Life Questionnaire was used to assess HRQoL at 1, 3, 6, and 12 months after surgery.
Results: M-GTET was associated with a larger number of lymph nodes dissected (p < 0.001), lower drainage volume (p < 0.001), shorter hospital stay (p < 0.001), and shorter axillary incision (p < 0.001). POSAS was more favorable in M-GTET. HRQoL was significantly better for MGTET in terms of less problems with scar (p < 0.001).
Conclusion: Our study suggests that MGTET provides better therapeutic, cosmetic, and HRQoL outcomes.
