Impact of adenotonsillectomy on quality of life in children with obstructive sleep disorders

Objectives: To determine the impact of adenoton-sillectomy on quality of life (QOL) in children with obstructive sleep disorders (OSDs) before and after surgery, Design: Prospective, observational, before-and-after trial. Setting: Seven tertiary pediatric otolaryngology practices. Patients: Convenience sample of 101 children (mean age, 6.2 years) with adenotonsillar hypertrophy and OSD scheduled for adeno tonsillectomy. Intervention: Adeno tonsillectomy was performed in children for OSDs. Quality of life was assessed using the Obstructive Sleep Disorders-6 survey, a validated instrument for detecting QOL change in children with OSDs. Surveys were completed at the initial office visit (visit 1), the day of surgery (visit 2), and at the postoperative office visit (visit 3). Physical characteristics were assessed using tonsillar and orocramofacial scales (visit 1). Satisfaction with health care decisions was assessed using the Satisfaction With Decision and Satisfaction With Office Visit scales (visit 1). Main Outcome Measures: Short-term changes in QOL before (visits I and 2) and after (visits 2 and 3) surgery. Results: Changes in QOL before surgery were trivial or small, and smaller than changes after surgery (mean change score, 0.18 vs 2.3; P<.001). Large, moderate, and small improvements in QOL were seen in 74.5%, 6.1%, and 7.1% of children, respectively. Sleep disturbance, care-giver concern, and physical suffering were the most improved domains, although significant changes also occurred for speech and swallowing problems, emotional disturbance, and activity limitations. Five percent of children had poorer QOL after surgery, but no predictive factors were identified. Conclusion: Adeno tonsillectomy produces large improvements in at least short-term QOL in most children with OSDs.
