Could a simple tube replace sleep surgery scopes?

This study tested a new diagnostic tool called high-resolution manometry (HRM) to see if it could accurately locate blockages in the upper airway of people with sleep apnea. Researchers compared HRM, which uses a thin tube to measure pressure, to the current standard procedure (DISE) that uses a camera while patients are asleep. The goal was to see if HRM could provide clearer, more objective information to help plan better treatments for 18 adults and children.
