Introduction:
Obstructive sleep apnea syndrome (OSAS) is a highly prevalent condition, particularly among at-risk populations such as patients with obesity, diabetes, or chronic respiratory disease. There is a growing need for simplified, automated diagnostic approaches that can be implemented outside specialized sleep laboratories.
Methods:
We conducted a prospective, interventional study in two hospital centers in Alsace (France), comparing an automated mandibular movement analysis device (Sunrise®) with standard ventilatory polygraphy (VP). Agreement between the two methods for determining the apnea-hypopnea index (AHI) was assessed using Bland-Altman analysis.
Results:
Thirty-seven patients were enrolled, from whom 29 pairs of recordings (78%) were suitable for analysis. Seven Sunrise® failures and one ventilatory polygraphy failure, were due mainly to sensor malfunctions or connectivity issues. In comparison with VP, Sunrise® tended to overestimate AHI, with a mean difference of +4.76 events/h. The limits of agreement ranged from -15.4 to +24.9 events/h, indicating moderate variability between the methods.
Conclusions:
The Sunrise® device demonstrates feasibility for use in non-expert clinical settings and shows reasonable agreement with ventilatory polygraphy, supporting its potential as a simplified screening tool for OSAS. However, these results should be interpreted cautiously, especially for high AHI, and technical limitations must be addressed in future "real world" studies.
