Can drug-induced sleep endoscopy (DISE) help determine the mechanisms for lack of response to surgery for obstructive sleep apnea (OSA)?
Background: The most common OSA surgical treatment in the U.S. is isolated palate surgery, even though it rarely eliminates OSA and achieves a meaningful reduction in severity in only 5 percent to 38 percent of patients. In an attempt to improve surgical outcomes, surgeons have performed hypopharyngeal procedures in combination with palate surgery, increasing the response rate to 35 percent to 62 percent of patients. Although several studies investigated palate and/or hypopharyngeal procedures, few have looked at non-responders to determine the mechanisms of response to surgery.
