ABSTRACT To assess the effectiveness of adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy.
Open, randomised controlled trial.
21 general hospitals and three academic centres in the Netherlands.
300 children aged 2-8 years requiring adenotonsillectomy.
Adenotonsillectomy compared with watchful waiting.
Episodes of fever, throat infections, upper respiratory tract infections, and health related quality of life.
During the median follow up period of 22 months, children in the adenotonsillectomy group had 2.97 episodes of fever per person year compared with 3.18 in the watchful waiting group (difference -0.21, 95% confidence interval -0.54 to 0.12), 0.56 throat infections per person year compared with 0.77 (-0.21, -0.36 to -0.06), and 5.47 upper respiratory tract infections per person year compared with 6.00 (-0.53, -0.97 to -0.08). No clinically relevant differences were found for health related quality of life. Adenotonsillectomy was more effective in children with a history of three to six throat infections than in those with none to two. 12 children had complications related to surgery.
Adenotonsillectomy has no major clinical benefits over watchful waiting in children with mild symptoms of throat infections or adenotonsillar hypertrophy.

    ABSTRACT: BACKGROUND:: In children presenting with obsessive compulsive disorder (OCD) and/or tics, especially those with a temporal association with streptococcal pharyngitis (e.g., PANDAS; Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus), there is speculation about whether tonsillectomy/adenoidectomy might improve the child's neuropsychiatric course. Our objective was to examine whether removal of tonsils and/or adenoids impacted streptococcal antibody titers, the timing of onset of OCD and/or tics, and the clinical severity of these symptoms. METHODS:: Study participants (n = 112; average age = 9.2 ± 2.4; 44 female) were recruited as part of a prospective investigation of neuropsychiatric phenomena with temporal association to streptococcal pharyngitis and examined by family history, diagnostic interview, physical examination, medical record review, psychological testing, and streptococcal antibodies and divided into surgical or non-surgery groups. The surgical group consisted of children having previously had a tonsillectomy and/or adenoidectomy (n=32). The remaining children were categorized as non-surgery (N=76). Measures of OCD and tic severity, streptococcal antibody titers, and PANDAS classification were compared between both groups. RESULTS:: There were no significant differences as determined by streptococcal antibody titers, PANDAS classification, and OCD or tic severity between the surgical and non-surgery groups. Most participants had surgery before onset of neuropsychiatric symptoms and surgery did not affect symptomology. CONCLUSIONS:: Streptococcal antibodies and neuropsychiatric symptom severity did not differ on the basis of surgical status. From these data we cannot support that tonsillectomy and adenoidectomy are likely to impact positively the course of OCD/tics or streptococcal antibody concentrations.

    ABSTRACT: Adenotonsillectomy (AT) is one of the most common pediatric surgical procedures performed in the United States; more than 530,000 are performed annually in children younger than 15 years of age. AT was traditionally performed for recurrent tonsillitis and its sequelae but in recent times, sleep-disordered breathing/obstructive sleep apnea in children has emerged as the primary indication for surgical removal of adenoids and tonsils. The new guidelines used by clinicians to identify children who are appropriate candidates for AT address indications based primarily on obstructive and infectious causes.
