Objective: To identify factors associated with multilevel collapse during Drug-Induced Sleep Endoscopy (DISE) in patients with obstructive sleep apnea (OSAHS).
Materials and Methods: Retrospective study of OSAHS patients who underwent DISE, using the VOTE classification. Multilevel collapse was defined as grade 2 obstruction in at least two levels. Sociodemographic, clinical, and anatomical variables were analyzed for their impact on multilevel collapse occurrence.
Results: A total of 91 patients were included, with a mean age of 50.7 years. Multilevel collapse was identified in 42.9% of cases and was significantly associated with a BMI ≥ 30 kg/m². Patients with retrognathia and/or nasal septum deviation had a lower prevalence of multilevel collapse, although this difference was not statistically significant.
Conclusion: This study confirms the high prevalence of multilevel collapse in OSAHS, identifying obesity as an independent predictor of its occurrence, highlighting the importance of weight loss in the therapeutic management of these patients.
