The harmonic scalpel and the electrothermal bipolar vessel sealing system (LIGASURE PRECISE) have been both shown to be safe and effective in thyroid surgery. The moderate dissection capabilities of the previous harmonic scalpel instruments available for thyroid surgery have led to an innovative technical improvement of the device (FOCUS) that has very recently been implemented and has been made available in 2008. Comparison of the utilization of this new device, however, with the electrothermal bipolar vessel sealer has not been performed in any study. The objective of this study is to compare the results of total thyroidectomy using the FOCUS to that with the LIGASURE device in respect to hemostasis, operative time and perioperative complications. All patients undergoing a total thyroidectomy in our endocrine surgery department are randomized into those operated with FOCUS (Group A) and those with LIGASURE (Group B).
