What volumetric changes in upper airway soft tissue structures can be viewed using magnetic resonance imaging (MRI) pre- and post-transoral robotic surgery (TORS)for obstructive sleep apnea (OSA)?
Background: Many OSA patients who have difficulty tolerating continuous positive airway pressure often seek surgical evaluation. TORS allows for direct visualization of, and better access to, the base of the tongue compared to open procedures, but it is unknown why some patients respond and other patients do not. MRI can examine how the upper airway soft tissue volumes change, or do not change, following surgical intervention.
