Key clinical point: Adenotonsillectomy does not improve cognitive function in preschoolers with mild obstructive sleep apnea, according to a prospective study.
Major finding: There was no significant difference in global IQ at 12 months, as measured by the Woodcock Johnson III Brief Intellectual Ability (BIA) test, between the 61 patients who underwent adenotonsillectomy and the 60 who did not. The mean W scores for BIA were 465.46 and 463.12, respectively (P = .29).
Study details: Randomized trial of 190 children with mild obstructive sleep apnea
Disclosures: The study was funded by the National Health and Medical Research Council, Sydney University, the Garnett Passe and Rodney Williams Memorial Foundation, and the Golden Casket, Brisbane. The authors said they have no relevant conflicts of interest.
