Adenotonsillectomy in obese children with obstructive sleep apnea syndrome: magnetic resonance imaging findings and considerations.

ABSTRACT:

Objective

The reasons why adenotonsillectomy (AT) is less effective treating obese children with obstructive sleep apnea syndrome (OSAS) are not understood. Thus, the aim of the study was to evaluate how anatomical factors contributing to airway obstruction are affected by AT in these children.

Methods

Twenty-seven obese children with OSAS (age 13.0 ± 2.3 y, body mass index Z-score 2.5 ± 0.3) underwent polysomnography and magnetic resonance imaging of the head during wakefulness before and after AT. Volumetric analysis of the upper airway and surrounding tissues was performed using commercial software (AMIRA®).

Results

Patients were followed for 6.1 ± 3.6 mo after AT. AT improved mean obstructive apnea-hypopnea index (AHI) from 23.7 ± 21.4 to 5.6 ± 8.7 (P < 0.001). Re
