Diagnostic techniques and surgical outcomes for persistent pediatric obstructive sleep apnea after adenotonsillectomy: A systematic review and meta-analysis
Abstract
OBJECTIVE
To evaluate the efficacy of upper airway surgery for children with persistent obstructive sleep apnea after adenotonsillectomy and to assess sleep study outcomes when Drug Induced Sleep Endoscopy, Cine MRI, or other imaging procedure is performed to assist in identifying the location of obstruction and planning surgery.
METHODS
Systematic review and meta-analysis was performed. Inclusion criteria was English-language studies with original data including pediatric patients with persistent OSA after T&A. Exclusion criteria included case reports and lack of pre and post-operative sleep study data. Data Sources were PubMed, Cochrane Central, and Embase from 2000 to 2018. PRISMA standards were followed for the selection and review of articles. The Newcastle-Ottawa Quality Assessment scale was used to score the quality of evidence of the studies. All manuscripts were reviewed independently by two investigators. Primary outcome measures were apnea-hypopnea index and minimum oxygen saturation. Data was pooled using a random-effects model.
RESULTS
Of the 1902 abstracts identified, 11 studies (214 patients) met inclusion criteria for systematic review, 5 with Drug Induced Sleep Endoscopy as the diagnostic technique, 4 with Cine MRI, and 2 with MRI/CT. All studies were case series. Most subjects had syndromic comorbidities and/or obesity. Ten studies (198 patients) were included in the meta-analysis. Overall, there was a change in apnea hypopnea index of -6.51 (95% CI, -8.17…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 214 participants or records.
