UNLABELLED: The aim of the study was to see whether a new technique of a neck dissection applying an ultrasonic activated (harmonic) scalpel would improve patient recovery.

MATERIAL AND METHODS: A prospective, non-randomized study was undertaken on 40 supraomohyoid neck dissections performed using a harmonic scalpel (20 pts) or electrocoagulation (20 pts). The evaluation included: operation time, intraoperative blood loss, postoperative seroma formation and pattern of wound healing.

RESULTS: The operative time (mean+/-SD) using a harmonic scalpel was significantly shorter (52+/-10 min vs. 86+/-22 min; p
CONCLUSION: The use of the harmonic scalpel during neck dissection led to diminished bleeding, shorter operative time, lesser seroma formation and better wound healing in the postoperative period.
