How do cine MRI and drug-induced sleep endoscopy (DISE) compare in identifying upper airway obstruction (UAO) sites in children with persistent obstructive sleep apnea (OSA) after adenotonsillectomy (AT)?

Figure 1. Cine magnetic resonance imaging showing upper airway obstruction. Sagittal images demonstrate the open (A, C) and narrowed airway (B, D) at the level of the tongue base (white arrow) and velum (arrow head)/tongue base (*). Posterior displacement of the tongue also caused posterior displacement of the soft palate (A, B). Axial images show the open (E) and narrowed airway (F) at the level of oropharynx/lateral walls (>) and tongue base (black arrow). Imaging technique prevents presentation of an example of concurrent obstruction at the level of the velum/oropharynx/lateral walls/tongue base in a single image.

Cine MRI and DISE documented single and multiple sites of UAO in children with persistent OSA after AT. Cine MRI and DISE findings were similar in the majority of the children.
Background: Children with obstructive sleep apnea (OSA) may have multiple sites of upper airway obstruction (UAO). A wide variety of techniques has been used to evaluate UAO. Cine magnetic resonance imaging (MRI) and DISE have been increasingly used to evaluate UAO in children with OSA.
