This report describes improvements in sleep, social communication, attention, repetitive behaviors, and hypersensitivity after adenotonsillectomy for obstructive sleep apnea in a 5-year-old female with an autism spectrum disorder. Improvements were documented via pre- and postsurgical measures of parent report, polysomnography, validated sleep and behavior scales, and the Autism Diagnostic Observation Schedule.
