AAP Grand Rounds 4:12 (2000) Snoring and Obstructive Sleep ApneaSource: Nieminen P, Tolonen U, Lopponen H. Snoring and obstructive sleep apnea in children: a 6-month follow-up study. Arch Otolaryngol Head Neck Surg. 2000;126:481486.
Nieminen and colleagues at the Oulu University Hospital in Finland prospectively evaluated children whose chief complaint was snoring in order to assess the utility of polysomnography (PSG) in diagnosing obstructive sleep apnea syndrome (OSAS), determine the efficacy of adenotonsillectomy in treating OSAS, and record the natural history of OSAS and primary snoring. Children with abnormal facial morphologic characteristics were excluded. Fifty-eight children (31 males, mean age 5.7 years) were compared to 30 non-snoring normal children (17 males, mean age 7.1 years). All children underwent a PSG which included leads for an oronasal thermistor for air movement, thoracoabdominal strain gauge for respiratory effort, pulse oximeter, body-position sensor, leg electromyograph for restlessness, and static charge-sensitive bed for position and movement. All recordings were "manually checked" by one of the authors. Of the 58 children with snoring, 27 had PSG consistent with obstructive sleep apnea syndrome (OSAS) and 31 were diagnosed with primary snoring. No abnormal
