Official title Effect of Tonsillectomy on Preventing Recurrent Streptococcal Throat Infections: A Randomized Controlled Trial
Description Tonsillectomy is widely used worldwide in recurrent streptococcal tonsillitis, but its effect remains unknown. In this randomized controlled trial, the effect of tonsillectomy (compared to watchful waiting) in preventing further culture proven symptomatic streptococcal pharyngitis episodes is studied. In addition, symptoms after the operation, side effects, and life quality issues are recorded.
