  Purpose
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.

Primary Outcome Measures:
  • Absolute percentage difference between groups of patients having pharyngitis with delayed recovery time defined by symptoms and blood sample values (crp, procalcitonin) [ Time Frame: 5 months follow up ]

Secondary Outcome Measures:
  • Absolute percentage difference of patients having group A streptococcal pharyngitis. [ Time Frame: 5 months follow up ]
  • Absolute percentage difference of patients having acute pharyngitis episode with and without medical consultation [ Time Frame: 5 months follow up ]
  • Difference in the number and quality (mild, severe) of symptomatic days (fever, sore throat, rhinitis, cough) [ Time Frame: 5 months follow up ]
  • Absolute percentage difference having harmful effects related to tonsillectomy (haemorrhage, soft tissue burns etc.) [ Time Frame: 5 months follow up ]

Enrollment: 87
Study Start Date: November 2007
Study Completion Date: June 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1
patients on waiting list for a minimum of 5 months. These patients receive no prophylactic intervention for their recurrent pharyngitis episodes.
Other: no intervention
No intervention (controls). Follow up started from the day of randomization.
Active Comparator: 2
Tonsillectomy as soon as possible after randomization (within 2-3 weeks).
Procedure: Tonsillectomy
Tonsillectomy under general anesthesia as a day surgery using diathermy or blunt dissection. Follow up started from the day of surgery.

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.
