Introduction: Thyroidectomy is among the most commonly performed procedures involving the endocrine glands and the development of advanced surgical methods combined with a strife for performing the operation in a manner that is minimally invasive for the patient has considerably increased the need for instruments that would limit surgical trauma.

Aim: To compare of the outcomes of total thyroidectomy operations with and without the use of ultrasonic harmonic FOCUS dissecting shears.

Material and methods: Eighty-two patients with a bilateral, non-toxic multinodular goiter were randomized to two groups of 41 patients each. Total thyroidectomy was performed in each patient. In the clip-ligation group (CL-G), during thyroidectomy, the superior thyroid vessels were clipped and bipolar coagulation was used to secure smaller vessels, whereas in the harmonic FOCUS group (HF-G), a harmonic device was used to dissect and divide all the thyroid vessels. The statistical analysis included the mean operative time, blood loss, postoperative morbidity and cost-effectiveness.

Results: HF-G vs. CL-G operations were shorter (45.4 ±8.7 min vs. 64.5 ±14.2 min; p < 0.001), characterized by a lower mean blood loss (29.9 ±9.8 ml vs. 56.8 ±11.0 ml; p < 0.001) and appeared to be more cost-effective (666.2 ±37.5 EUR vs. 718.0 ±69.2 EUR; p < 0.01). No major complications were observed in both groups.

Conclusions: In total thyroidectomy operations, the harmonic FOCUS is safe and facilitates dissection, allowing for a significant decrease in operative time. Other benefits include lower blood loss and a slightly decreased cost of the procedure.
