title: Temperature-controlled radiofrequency tonsil reduction in children.
abstract: OBJECTIVE
  To evaluate the safety and efficacy of temperature-controlled radiofrequency tonsil reduction in the treatment of children with a sleep-related breathing disorder associated with tonsillar obstructive hypertrophy.
  
  
  METHODS
  Prospective, nonrandomized, case series feasibility study of children meeting the criteria for tonsillectomy or adenotonsillectomy for the treatment of an obstructive sleep-related breathing disorder.
  
  
  METHODS
  Community-based hospital. Patients Ten children, aged 4 to 13 years, presenting consecutively to a community-based otolaryngology practice with tonsillar or adenotonsillar obstructive hypertrophy implicated clinically in causing a sleep-related breathing disorder; their parents consenting to temperature-controlled radiofrequency tonsil reduction instead of surgical tonsillectomy. Intervention Temperature-controlled radiofrequency tonsil reduction, along with surgical adenoidectomy, if adenoids were present, under general anesthesia.
  
  
  METHODS
  Tonsil size reduction, treatment morbidity, and symptom improvement with follow-up to 1 year. Baseline and 3-month posttreatment polysomnographic data were used.
  
  
  RESULTS
  There was a reduction in tonsil size at 1 year of 75.0% on average, without evidence of regrowth during the 1-year follow-up. All children were drinking liquids in the recovery room, and most were eating soft diets within 6 hours; 8 of the 10 children were eating a normal diet by day 5. On average, the return to normal activity was 3.9 days, with 2.9 days of parental loss of work time. Quality-of-life variables all improved. Snore indexes decreased by 88.6%. Polysomnography at 3 months revealed an 84.2% reduction in the apnea index and a 52.3% reduction in the apnea/hypopnea index. There were no complications.
  
  
  CONCLUSIONS
  Temperature-controlled radiofrequency tonsil reduction seems to be a safe, effective, and minimally morbid treatment for tonsil hypertrophy in children with obstructive sleep-related breathing disorders.
