Thyroid surgery with the new harmonic scalpel: a prospective randomised study. Surgery 2011; 149: 411–415.

Published: 27th September 2011

Authors: Markogiannakis H, Kekis PB, Memos N, Alevizos L, Tsamis D, Michalopoulos NV et al. et al.

Conclusion

This study included 90 procedures and compared the existing harmonic scalpel (Harmonic Ace) with a new one (Focus). All clinical and outcome parameters were similar, but the procedures were quicker with the new device: mean 63 min vs. 76 min, P=0.009.
