Clinical case control study analysis of vestibular function in patients with obstructive sleep apnea-hypopnea syndrome.

Background: To investigate the effects of hypoxia degree and sleep duration on vestibular function in obstructive sleep apnea-hypopnea syndrome (OSAHS) patients. We made further study of the low oxygen levels of OSAHS and hypoxic duration on the impact of vestibular function, and further studied the OSAHS the longest apnea time and Vestibular Evoked Myogenic Potential (VEMP) abnormal rate and the relationship between the vestibular function of canal paralysis (CP).

Methods: A total of 87 OSAHS patients and 47 healthy individuals were enrolled in this study.
