This research study aims to compare the accuracy of a home sleep apnea testing device (used as part of a home sleep study) for diagnosing obstructive sleep apnea in children who have had their adenoid and/or tonsils surgically removed, with an in-lab overnight sleep study. Children eligible for this study must be between the ages of 5 and 12. Participants will be randomly assigned to determine the order in which they complete the two sleep studies. After both the in-lab and home sleep studies are completed, families will be asked to complete questionnaires assessing the acceptability of home sleep apnea testing, as well as their preference between the two testing methods.
