Objectives: The aim of this study is to evaluate the efficiency of microdebrider intracapsular tonsillotomy compared with conventional extracapsular tonsillectomy.Study Design: A prospective randomized controlled study was designed to compare between the two groups. Time of operation, estimated blood loss, postoperative pain, rate of postoperative hemorrhage, tonsillar fossa healing, swallowing and complication rate were evaluated.Results: Regarding intraoperative blood loss the conventional group had significantly lower blood loss (P <0.05). The microdebrider group showed significantly less pain and better swallowing function (P<0.05) than the conventional group. There were no significant differences in operative time or wound healing. No postoperative complications as recurrence or hemorrhage were detected in either group. Conclusion: Microdebrider intracapsular tonsillotomy is an effective method to remove tonsillar tissue. There was significantly less pain and better swallowing function compared to the conventional extracapsular tonsillectomy group.
