Introduction: Tonsillectomy is one of the most common procedures performed by otolaryngologists. Intraoperative bleeding is a significant problem, which requires hemostasis and causes prolonged operative time. Several different techniques are used to perform this operation. The Ligasure Vessel Sealing System (LVSST) has been widely used in head and neck surgery because of its effectiveness and safety.

Methods: This project was conducted at the department of otolaryngology of Besat Hospital, Hamadan, Iran. In this double-blinded clinical trial, 82 subjects, who were candidates for tonsillectomy and qualified in eligible criteria, were randomly assigned to 2 group of 41 subjects. Surgery was performed using Lvsst for one group and cold knife dissection for the other group. Measured outcomes for efficacy and adverse effect were intraoperative blood loss, operation time, post-operative pain in visual analogue scale, and post-operative bleeding for28 days after surgery. The SPSS 16 software was used for data analysis.

Results: Method of LVSST was significantly better than CKT in operation time and bleeding on the first day after surgery, yet, postoperative blood loss in the first week after surgery in LVSST group was significantly higher than the CKT group. Severity of sore throat after surgery with Ligasure was higher than CKT the group, however the difference was not significant. Intraoperative bleeding in the LVSST group was significantly lower than that of the CKT group (P = 0.000).

Conclusions: The results of this study showed that the prevalence of respiratory symptoms LVSST was better than CKT in intraoperative (not post-operative) blood loss and operation time, yet there was no difference regarding postoperative pain. For workers with a history of allergies, this ratio is higher.
