Childhood Adenotonsillectomy Study for Children With OSAS
A Randomized Controlled Study of Adenotonsillectomy for Children With Obstructive Sleep Apnea Syndrome

The purpose of this research is to determine the effect of adenotonsillectomy surgery (removal of tonsils and adenoids) on obstructive sleep apnea syndrome (OSAS) in children. OSAS can cause health problems including poor growth, high blood pressure, diabetes and behavioral and learning difficulties. Although adenotonsillectomy is the usual treatment for children with OSAS, it is not known with any certainty if the child's OSAS symptoms improve afterwards. This study will help determine if improvement occurs or if it does not. It will also look at whether certain groups, such as children who are overweight or of different ethnicities, are helped by the surgery.

Because adenotonsillectomy is the usual treatment for OSAS, all children in the study will get surgery. However, in order to assess the extent to which adenotonsillectomy surgery improves breathing disturbances and sleep quality in children with OSAS, two groups will be studied. One group will get surgery early (one month after enrollment) and the other group will be re-evaluated for surgery within 7 months of enrollment.

Children in both groups will be closely monitored through the 7-8 month study period and sleep and health educational materials will be provided to assist in establishing healthy habits.

Inclusion Criteria:

  1. Ages 5.0 to 9.99 years at time of screening.
  2. Diagnosed with Obstructive Sleep Apnea defined as: Obstructive Apnea Index (OAI) ≥ 1 or Apnea Hypopnea Index (AHI) ≥ 2, confirmed on nocturnal, laboratory-based PSG and Parental report of habitual snoring (on average occurring >3 nights per week).
  3. Tonsillar hypertrophy ≥ 1 based on a standardized scale of 0-4: 0 = surgically absent, 1 = taking up < 25% of the airway, 2 = 25 - 50 % of the airway,3 = 50 - 75 % of the airway, 4 = > 75% of the airway
  4. Deemed to be a surgical candidate for AT by ENT evaluation.

Exclusion Criteria:

  1. Recurrent tonsillitis defined as: >3 episodes in each of 3 years, 5 episodes in each of 2 years, or 7 episodes in one year
  2. Craniofacial anomalies, including cleft lip and palate or sub-mucosal cleft palate or any anatomic or systemic condition which would interfere with general anesthesia or removal of tonsils and adenoid tissue in the standard fashion
  3. Obstructive breathing while awake that merits prompt AT in the opinion of the child's physician
  4. Severe OSAS or significant hypoxemia requiring immediate AT as defined by: OAI>20 or AHI>30, desaturation defined as SaO2 <90% for more than 2% sleep time
  5. Apnea hypopnea indices in the normal range (OAI < 1 and AHI <2)

  8. Severe health problems that could be exacerbated by delayed treatment for OSAS Including: Doctor-diagnosed heart disease or cor pulmonale, history of Stage II Hypertension (HTN) defined as > 99% percentile plus 5 mmHg for either systolic or diastolic, based on the age, gender, and height and/or requiring medication, therapy for failure to thrive or short stature, psychiatric or behavioral disorders requiring or likely to require initiation of new medication, therapy, or other specific treatment. School aged children, parental report of excessive daytime sleepiness defined as unable to maintain wakefulness, at least three times per week, in routine activities in school or home, despite adequate opportunity to sleep.
