Abstract

Background: Increased daytime sleepiness is a frequently reported symptom in patients with pronounced dysgnathia. Objectives: This study investigated possible correlations using home peripheral arterial tonometry (PAT) and oropharyngeal airway volume determination in patients with dysgnathia and daytime sleepiness. Methods: Twenty patients (13 male, median age 27.6 ± 6.8 years) with abnormal sleep history and 10 skeletal neutral configured controls (6 male, median age 29.5 ± 4.2 years) with normal sleep history were examined. Patients and controls were evaluated for apnoea–hypopnoea index (AHI), respiratory disturbance index (RDI), oxygen desaturation index (ODI), snoring volume (dB), total sleep time (TST) and REM‐percentage (REM). Airway volumetry was measured via CBCT. Individual user experience for PAT was assessed using the User Experience Questionnaire (UEQ). Results: Patients had significantly higher respiratory scores than controls. AHI increased 4.6‐fold (p =.006), RDI 2.5‐fold (p =.008) and ODI 6.4‐fold (p <.001). Oropharyngeal volumes showed a 30% decrease (p =.003). dB, TST and REM showed no significant differences. AHI (r = −.51; p =.005), ODI (r = −.60; p <.001) and RDI (r = −.45; p =.016) correlated negatively with pharyngeal volume. Wits appraisal correlated negatively with oropharyngeal volume (r = −.47; p =.010) and positively with AHI (r =.41; p =.03) and ODI (r =.49; p =.007). dB and TST (r = −.49; p =.008) and REM and RDI (r = −.43; p =.02) correlated negatively. UEQ‐KPI (2.17 ± 0.24) confirmed excellent usability of PAT. Conclusion: Patients with mandibular retrognathia and abnormal sleep history showed significantly higher respiratory indices and smaller oropharyngeal volumes than neutrally configured controls. The dygnathia severity directly influenced the risk of obstructive sleep apnoea. [ABSTRACT FROM AUTHOR]
