Recurrent Throat Infections and Tonsillectomy

April 17, 2012 updated by: Oulu University Hospital
The purpose of this study is to find out if tonsillectomy reduces the short-term risk of having an objectively confirmed (sequential changes in serum crp and procalcitonin levels) delayed pharyngitis episode among patients suffering from recurrent pharyngitis episodes. Other aims are to find out the effect of tonsillectomy to reduce the number of pharyngitis episodes or symptoms. Still, the possible disadvantages of tonsillectomy and changes in the quality of life after tonsillectomy among these patients are examined.

Detailed Description

We will have a prospective randomized study. We allocated 87 consecutive patients referred for tonsillectomy randomly in two groups: tonsilectomy group or waiting list(control group). Patients in tonsillectomy group were operated as soon as possible and data on postoperative morbidity was collected. In the control group, patients were placed on our normal waiting list and they were operated on in normal time (about 5-6 months). The data on preoperative morbidity was collected. All the pharyngitis episodes were treated by a study investigator and laboratory tests (crp, procalcitonin) were taken at that time and after three days. In addition, the patients record their symptoms on a diary.
