Role of DISE in the surgical outcome for patients with obstructive sleep apnea

Abstract

Purpose: To investigate and compare the surgical outcomes of DISE and non-DISE-guided surgery in cases with obstructive sleep apnea.

Methods: Sixty-three patients with severe OSA and BMI ≤35 kg/m² were included in the study. Patients were randomly divided into group A where surgical intervention was performed without DISE, and group B where surgery was planned according to the findings of DISE.

Results: In group A, the mean AHI, LO₂, and Snoring index showed a highly significant improvement (P < 0.0001). Group B had highly significant improvements as regards PSG data (P < 0.0001). High significant differences exist when comparing the operative time of both groups (P < 0.0001). On comparing the success rates in both groups, no statistically significant differences were reported (p = 0.6885).

Conclusion: Preoperative topo-diagnosis with DISE does not significantly affect the surgical outcomes in OSA. Primary OSA cases could benefit from a no-DISE cost-effective surgical protocol that entails multilevel surgical interventions in a reasonable time.
