Abstract

BACKGROUND AND OBJECTIVES
Drug-induced sedation endoscopy (DISE) has recently gained popularity among otolaryngologists because it can provide direct information of upper airway obstruction in patients with obstructive sleep apnea (OSA). In that regard, we examined how DISE examination affected the decision of clinician's treatment plan and the consequent patient's compliance in OSA patients.
SUBJECTS AND METHOD
All enrolled patients were classified into two groups according to the method of upper airway evaluation employed: a physical examination only group and a physical examination combined with DISE group. The clinician's treatment plan was categorized into the following four groups: sleep surgery, positive airway pressure, oral appliance, and sleep surgery combined with oral appliance. The change of patient's compliance was also evaluated.
RESULTS
There were several differences in how DISE evaluation affected the decision of clinician's treatment plan and patient's compliance between the two groups. The rate for sleep surgery fell from 69.6% to 15.9%; on the other hand, the rate for positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 13.0% to 36.2%, 14.5% to 26.6%, and 2.9% to 21.3%, respectively. The patient's compliance also changed after DISE evaluation: sleep surgery, positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 78.1% to 87.9%, 16.7% to 76.0%, 25.0% to 87.3%, and 50.0% to 91.03%, respectively.
CONCLUSION
We found that DISE examination influences the decision of clinician's treatment plan and patient's compliance. We suggest additional cohort studies to confirm these findings.
