Objectives: (1) To assess outcomes in children undergoing adenoidectomy for the treatment of mild obstructive sleep apnea (OSA). (2) To identify clinical factors that predict which children will have persistent obstruction following adenoidectomy.
Study design: Case series with chart review over a 10-year period.
Setting: Tertiary children's hospital.
Subjects and methods: Children between 2 and 17 years old undergoing adenoidectomy for treatment of mild OSA (obstructive apnea-hypopnea index [AHI] between 1 and 5 on polysomnogram) were included. The need for additional medical or surgical intervention following adenoidectomy was recorded. When available, postoperative polysomnogram data were reviewed.
Results: In total, 134 children with a mean age of 5.4 years were included. Fifty-three percent (n = 71) were female and 57% (n = 76) were black. The mean (SD) baseline AHI was 2.2 (1.09). Caregivers reported a moderate impact of sleep disturbance on quality of life with a mean (SD) preoperative total OSA-18 score of 64.1 (19.28). Postadenoidectomy outcomes were reported for 105 patients (78%) with a mean follow-up time of 6 months. Sixty-nine percent (n = 72) of children had resolution of obstructive symptoms. While 31% (n = 33) of children required additional intervention following adenoidectomy, only 6.8% (n = 9) underwent a subsequent tonsillectomy. Demographic factors such as age and baseline AHI did not predict which children required additional treatment following adenoidectomy.
Conclusion: Adenoidectomy may be an effective treatment for mild OSA. A randomized trial comparing outcomes for adenoidectomy and adenotonsillectomy is needed to determine the ideal surgical treatment for nonsevere OSA in children.
