Outcomes of Children with Mild Obstructive Sleep Apnea Treated Nonsurgically: A Retrospective Review

Abstract

Objective

Obstructive sleep apnea (OSA) is characterized by partial or complete obstruction of the upper airway and is commonly caused by adenotonsillar hypertrophy in children. Accordingly, adenotonsillectomy is considered first-line treatment. However, in cases of mild OSA, nonsurgical management has been proposed as an alternative. The purpose of this study was to determine the outcomes of pediatric patients with mild obstructive sleep apnea (OSA) treated without surgical intervention.

Study Design

Case series with chart review.

Setting

Tertiary care university medical center.

Subjects and Methods

The medical records of children ages 2 to 18 years with OSA at Boston Medical Center from January 2000 to April 2017 were reviewed. Children with mild OSA (apnea- hypopnea index [AHI] between 1 and 5), who were managed nonsurgically and had serial polysomnograms, were included. Serial sleep studies were compared to assess for patterns of change.

Results

Of the 201 patients with mild OSA who were identified, 104 (52%) opted for initial nonsurgical management. Of those, 91 had a follow-up sleep study to reassess their OSA. Forty-two (46 %) had a greater than 20% decrease in AHI and 38 (41%) had a greater than 20% increase on the second sleep study. The remaining 11 had changes less than 20% in either direction. There was not a significant difference in the proportion of patients with an increase vs decrease in AHI on follow-up sleep study (P > .05).

Conclusions

Mild pediatric OSA has approximately equal chances of worsening or improvement over time without surgical intervention, which is useful for counseling parents on treatment options.
