IRCT201010091138N3 IRCT 2011-06-07 Guilan University of Medical Sciences, Vice Chancellor for Research Effect of radiofrequency tonsillectomy in recurrent tonsillitis The results of radiofrequency tonsillectomy compared with conventional cold dissection tonsillectomy in recovery of adults with recurrent tonsillitis. 2008-04-08 anticipated 62 Complete https://irct.ir/trial/177 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment. 2-3 Chronic Tonsillitis. Intervention 1: Surgery will be done under general anesthesia and the operation in control group will be done by standard method of cold dissection tonsillectomy (i.e. dissecting the palatal tonsils from their bed by surgical knife and separating and totally removal of the tonsils from their sites). Duration of operation is measured according to the time, when surgical field is exposed ( after accomplishing the anesthesia ) till the moment that the surgeon is sure that there is no bleeding in the field of operation. At the end of the procedure, the amount of bleeding is estimated by measuring the blood volume in the vacuum bottle and also by counting the surgical gauzes, used in the operating room during surgery. The pain scale after surgery is measured by Visual Analogue Scale from zero to ten centimeters in the 1st, 3rd, 5th and 10th days after surgery The patients are asked about taking analgesia after surgery during the afore-mentioned days. The patients are also asked about the frequency of tonsillitis & pharyngitis during previous months, and at the same time the faucial tonsils are compared with their pre operation condition according to their size in the 6th, 12th and 15th months after surgery. Intervention 2: With the patient under general anesthesia and in the Rose position, the oropharynx was exposed by use of a Davis gag, and bipolar-linear RFITT probe (Celon AG Medical Instruments, Teltow/Berlin, Germany) was introduced into the crypts of the tonsils. The RF generator working frequency was 470 kHz, which was set at 7 W during the procedure. The power was constantly controlled by the system, terminating the energy application automatically once the thermal lesion was created. Five points (i.e., tonsillar crypts, including crypts of inferior and superior poles) for grades 1 and 2 tonsils, seven points for grade 3, and nine points for grade 4 tonsils were probed.

Postsurgical pain. Timepoint: on days 1, 3, 5 and 10 after surgery. Method of measurement: Visual Analogue Scale (VAS). Recurrence of tonsillitis/pharyngitis episodes. Timepoint: on months 6, 12 and 15 after surgery. Method of measurement: ask from patient and periodic check-up. Weight. Timepoint: in the 3rd, 10th and 20th days after surgery. Method of measurement: scale. Intraoperative bleeding. Timepoint: During and end of surgery. Method of measurement: measuring the blood volume in the vacuum bottle and also by counting the surgical gauzes.
