title: Tonsillectomy versus non-surgical treatment for chronic / recurrent acute tonsillitis.
abstract: BACKGROUND
  Surgical removal of the tonsils (tonsillectomy) is a common but controversial ENT operation.
  
  
  OBJECTIVE
  To determine the effect of tonsillectomy in patients with chronic/recurrent acute tonsillitis.
  
  
  METHODS
  Cochrane Controlled Trials Register, Medline, Embase, bibliographies.
  
  
  METHODS
  Randomised controlled trials comparing tonsillectomy with non-surgical treatment in adults and children with chronic/recurrent acute tonsillitis. Trials which included reduction in the number and severity of tonsillitis and sore throat as main outcome measures.
  
  
  METHODS
  Two authors applied the inclusion/exclusion criteria independently.
  
  
  RESULTS
  No trials evaluating the effectiveness of tonsillectomy in adults were identified. Two trials from Pittsburgh assessed tonsillectomy in children. Significant baseline differences between the surgical and non-surgical groups and the inclusion of children who also underwent adenoidectomy prevent firm conclusions being drawn from the fully published trial. Limited and insufficient information is available from the second study; further details are awaited.
  
  
  CONCLUSIONS
  The effectiveness of tonsillectomy has not been formally evaluated. Further trials addressing relevant outcome measure are required.
