Abstract:Objective To explore the clinical value of STOP-BANG questionnaire (SBQ), mandibular width and CT measurements at different levels of upper airway for obstructive sleep apnea hypopnea syndrome (OSAHS) screening. Methods Sixty suspected OSAHS patients who were admitted to the Department of Otorhinolaryngology, Liuzhou People’s Hospital from Sept 2020 to May 2021 were included. All the patients underwent SBQ, mandibular width measurement, upper airway CT measurement and polysomnography (PSG). Results All the subjects were divided into three groups according to sleep apnea hypopnea index (AHI): Non-OSAHS group, mild to moderate OSAHS group, and severe OSAHS group. The differences in gender and age among the three groups were statistically insignificant. There were significant differences in SBQ score, mandibular width, coronal and sagittal diameters of soft palate among the three groups (all P<0.05). The SBQ score of the severe OSAHS group was significantly higher than those of the mild to moderate and non-OSAHS groups (both P<0.05). Logistic regression analysis found that SBQ score and mandible width were independent risk factors for OSAHS. Compared with single SBQ as a diagnostic index, mandibular width combined with SBQ could improve the sensitivity of preliminary screening in OSAHS. Conclusions SBQ, mandibular width, sagittal and coronal diameters of the retropalatal region, coronal diameters of uvula and retroglottal region are closely related to the severity of OSAHS. SBQ combined with mandibular width measurement is helpful for preliminary screening of OSAHS and is suitable for OSAHS risk screening in outpatients and surgical patients.
