Relating three-dimensional airway measurements to the apnea-hypopnea index in pediatric sleep apnea patients.

Objectives: (a) To evaluate three-dimensional radiographic airway analysis as it relates to the pre-test probability for sleep apnea in pediatric patients, and (b) to develop cut-off values for measurements showing promising results.

Setting And Sample Population: A consecutive series of pediatric patients between the ages of 7 and 17 years, referred for a sleep study were recruited. Cone beam computed tomography (CBCT) scans were acquired for 103 subjects within one month following the sleep study.

Comparing two pediatric sleep questionnaires: The Pediatric Sleep Questionnaire (PSQ) and a set of 6 hierarchically arranged questions (6Q).

Objective: To compare the Pediatric Sleep Questionnaire (PSQ) and a less time-consuming set of 6 hierarchically arranged questions (6Q) as they relate to the pre-test probability for sleep apnea in pediatric patients.

Methods: Parents of 116 subjects between the ages of 7 and 17 answered two sleep questionnaires (the PSQ and the 6Q) distributed in random order before the subjects had sleep studies. Correlation coefficients were used for apnea-hypopnea index (AHI) prediction, while the area under the curve (AUC) was calculated for sleep apnea classification prediction.
