 Patients who are referred to either the clinic of Dr. Joseph Dort or Dr. Wayne Matthews and are deemed to benefit from a modified radical neck dissection alone or as part of treatment for head and neck cancer will be given an opportunity to be a subject in this study. Once informed consent for both the surgery and the study is obtained, the lead author will be contacted and randomization will occur using a computer generated block-randomization allocation. The neck dissection will be carried out in the operating room using either electrocautery control group or harmonic scalpel experimental group. The primary outcomes, blood loss mLs and operative time minutes will be assessed at the time of surgery. The blood loss in milliliters will be calculated using suction canister output, weight of sponges and irrigation used. The operative time in minutes will be calculated between the beginning of the actual neck dissection to the completion of the neck dissection defined as the removal of the surgical specimen and hemostasis of the surgical field. Intraoperative complications, namely vascular, nerve damage and lymphatic damage will be assessed at the time of surgery. Post-operative complications, both early and late will be assessed after the surgery using the Clavien post-operative complication scale. In addition, the length of time that operative drains are left in the neck will be measured with all drains being removed when their 24 hour drain output is less than 20 mls. Patients will then be followed up 2 weeks after their hospital discharge in the surgeons clinic or the Tom Baker Cancer Centre.
