Adenotonsillectomy in Obese Children With Obstructive Sleep Apnea Syndrome: Magnetic Resonance Imaging Findings and Considerations

This is the first report to quantify volumetric changes in the upper airway in obese children with OSAS after adenotonsillectomy showing significant residual adenoid tissue and an increase in the volume of the tongue and soft palate. These findings could explain the low success rate of AT reported in obese children with OSAS and are important considerations for clinicians treating these children.

Fiber-Optic Sleep Endoscopy in Children With Persistent Obstructive Sleep Apnea: Inter-Observer Correlation and Comparison With Awake Endoscopy

Sleep endoscopy is a consistently reliable tool for identifying the site of obstruction in children with persistent OSA. Though anesthetic induced sleep is not a perfect model for real sleep, the technique demonstrably guides further therapy better than awake endoscopy.

Positional OSA Part 1: Towards a Clinical Classification System for Position-Dependent Obstructive Sleep Apnoea

In 1984, Cartwright suggested that physicians should differentiate between patients with either positional obstructive sleep apnoea (POSA) or non-positional OSA. He introduced the arbitrary cut-off point of a difference of 50 % or more in apnoea index between supine and non-supine positions. In this study, a panel of three field experts developed consensus on Amsterdam Positional OSA Classification resulting in the consensus standard used to calibrate the new classification.

Obstructive Sleep Apnea and Severe Maternal-Infant Morbidity/Mortality in the United States, 1998–2009

OSA was associated with increased odds of pregnancy-related morbidities including preeclampsia (OR, 2.5; 95% CI, 2.2–2.9), eclampsia (OR, 5.4; 95% CI, 3.3–8.9), cardiomyopathy (OR, 9.0; 95% CI, 7.5–10.9), and pulmonary embolism (OR, 4.5; 95% CI, 2.3–8.9). Women with OSA experienced a more than fivefold increased odds of in-hospital mortality (95% CI, 2.4–11.5). Obstructive sleep apnea is associated with severe maternal morbidity, cardiovascular morbidity, and in-hospital death.
