Introduction: First-line treatment for patients with obstructive sleep apnea (OSA) is continuous positive airway pressure (CPAP) therapy. However, many patients cannot use CPAP sufficiently. With drug-induced endoscopy (DISE), it is possible to assess the collapse pattern in the upper airway. The aim of this work was to evaluate a collective of patients with CPAP usage problems using DISE, in order to evaluate their usage problems and therapy recommendations. Methods: Over a period of 5 years, all patients with an apnea–hypopnea index (AHI) of at least 15/h were retrospectively evaluated using DISE. The recommended treatment options were then analyzed. Results: Data analysis of 210 patients showed that about two thirds reported mask problems as the cause of non-adherence to CPAP. A complete concentric collapse (CCC) could be excluded in 75%. These patients had a lower AHI and more frequent tonsillectomy (TE) than patients with CCC. Double the number of patients with a body mass index (BMI) > 35 kg/m2 had a CCC compared to those with a BMI < 35 kg/m2. Among patients with similar BMI and AHI, CCC was twice as likely to be found in patients without TE. Conclusion: The course of treatment recommended for OSA often differs, depending on CCC, BMI > 35 kg/m2, and previous TE.
