ADOPTING THE OPERATING MICROSCOPE IN THYROID SURGERY: SAFETY, EFFICIENCY, AND ERGONOMICS

Background. Our aim was to assess the safety and efficiency of operating microscope use by surgeons in thyroid surgery to reduce static neck flexion. Methods. A retrospective case review comparing thyroidectomies performed using an operating microscope to those using surgical loupes was done. Operative times and incidence of complications were compared between total thyroidectomy procedures done with either microscope or loupes. Results. The use of microscope in 51 thyroidectomies (including 20 for malignancy with central compartment node dissection [CND) and 9 for substernal goiter [SG]) was compared with 65 cases (15 with CND and 11 with SG) done previously using loupes. Surgical times using the microscope were longer (p = .0001), but the increase was significant only in the subset of patients who underwent thyroidectomy with CND. There was no difference in complications between the groups. Conclusion. The use of an operating microscope during thyroidectomy is safe with modest increases in surgical time.
