Modifications in Upper Airway Collapsibility during Sleep Endoscopy with a Mandibular Positioner: Study in Snorers and Obstructive Sleep Apnea Patients.

The MAD simulator reduces collapsibility at all levels and in all severity groups. Residual collapses suitable for combined treatments were able to be identified. This highlights the need for individualized patient selection, as upper airway collapsibility exhibits variable improvement or worsening with the MAD simulator regardless of the severity of the condition.
