Study Objectives: In view of the risk that surgical repair of cleft palate may induce or worsen obstructive sleep apnea (OSA), the goal of this study was to assess presurgical and postsurgical polysomnography (PSG) results for children who underwent primary palatoplasty. Methods: Retrospective case-control series for children with cleft palate repair performed between January 2008 and December 2016 at a tertiary pediatric center. Children underwent PSG before and after surgery. Results: Sixty-four children (53.1% female) with a mean age of 2.0 ± 2.8 years (range 0.6-16.4) were included in the study. Pierre-Robin sequence was the most common comorbidity (67%). Before palatal repair, the mean obstructive apnea-hypopnea index (oAHI) was 3.4 ± 3.9 (range 0-17.9) events/h; this did not significantly change, with 5.9 ± 14.5 (range 0-105.7) events/h after surgery (P = 0.30). However, 34.4% of patients had a worsening of more than 1 obstructive event/h and 18.9% had a worsening of 5 or more obstructive events/h. The presence of a concomitant syndrome (eg, Treacher Collins) was a risk factor for postoperative OSA (odds ratio 4.2, 95% confidence interval 1.1-15.8, P = .03) Conclusions: OSA did not develop or worsen following primary palatoplasty. However, the oAHI increased by 5 or more events/h in approximately 20% of study participants. The presence of a syndrome was the only factor predictive of worsening OSA after palatoplasty. These findings suggest that palatoplasty does not worsen or cause OSA in most patients, and that nonsyndromic children are at low risk for the development or worsening of OSA.

We deemed 34% of decisions regarding the management of obstructive sleep apnea in children without tonsillar hypertrophy to be evidence based and found that sharing the basis for decisions did not improve the percentage of evidence-based decisions over time. These findings reflect significant evidence gaps and highlight the need for a systematic literature evaluation to identify best practice in managing this population. We recommend that these evidence gaps be further characterized and incorporated into an agenda for future research.

In neonates with PRS treated with MD for severe airway obstruction, the omission of a consolidation period does not appear to significantly affect the complication rate or resolution of airway obstruction.
