Coblation versus traditional tonsillectomy: A double blind randomized controlled trial

Abstract

BACKGROUND: Coblation tonsillectomy is a new surgical technique and demands further research to be proven as a suitable and standard method of tonsillectomy. This study compares coblation and traditional tonsillectomy techniques in view of their advantages and complications. METHODS: In a prospective double-blind randomized controlled trial information on operation time, intraoperative blood loss, postoperative pain, time needed to regain the normal diet and activity and post-operative hemorrhage were gathered and compared between two groups containing 47 patients in each group. RESULTS: We found statistically significant differences in operation time (p < 0.05), intraoperative blood loss (p < 0.05), postoperative pain (p < 0.001), time needed to find back the normal diet (p < 0.001) and normal activity (p < 0.001). However, post operation hemorrhage (p > 0.5) was not significantly different between two groups. CONCLUSIONS: This study revealed a significantly less intraoperative or postoperative complications and morbidity in coblation tonsillectomy in comparison with traditional method. Coblation was associated with less pain and quick return to normal diet and daily activity. These findings addressed coblation tonsillectomy as an advanced method.
