Coblation Versus Conventional Tonsillectomy: A Double Blind Randomized Controlled Trial

Post tonsillectomy bleeding and pain are two main problems following traditional tonsillectomy. Coblation therapy (controlled ablation) was first used in tonsillectomy in 2001. A great amount of literature debated around its use with controversial opinions regarding its benefits, efficacy, and cost. This is a prospective double-blind randomized controlled study that compares between coblation tonsillectomy and conventional tonsillectomy as regard operative time, operative blood loss, time needed to return back to the normal activity and diet, and incidence of postoperative hemorrhage whether primary or secondary. The study included 1004 patients with mean age of 10.4 years (range from 4 to 35 years). The first group (coblation tonsillectomy group) included 507 patients, age ranging from 4 to 35 years with mean age 15.1 year. This group included 277 female (54.6%) and 230 male (45.4%). The second group (conventional tonsillectomy group) included 497 patients, age ranging from 4 to 24 years and mean age 14.7 years. This group included 274 female (55.1%) and 223 male (44.9%). Coblation tonsillectomy offers significant advantages over dissection method with less operative time, decreased intraoperative blood loss, early restoration of daily activities and normal diet. However coblation tonsillectomy is associated with a higher incidence of secondary hemorrhage.
