Abstract :Obstructive sleep apnea syndrome (OSAS) is a common breathing disorder that is characterized by snoring, apnea and hypopnea attacks as a result of airway obstruction during sleep, and can lead to hearing loss. OSAS can cause complications in many organ systems associated with ischemia and intermittent hypoxia that develop with recurrent apnea attacks. Because the cochlea is highly dependent on the amount of oxygen, repeated apnea attacks can cause damage to cochlear cells. One study found that obstructive sleep apnea increases the likelihood of hearing loss by 21%. This study aims to determine the effect of OSAS on hearing and raise awareness on this issue by compiling studies in the literature examining the relationship between obstructive sleep apnea syndrome and hearing loss. In studies conducted with pure tone audiometry evaluation in individuals with OSAS, it has been reported that hearing thresholds are higher, especially at high frequencies. In studies where OSAS patients were evaluated with otoacoustic emission (OAE) measurement, the results varied, but lower repeatability, signal-to-noise ratio and amplitude were obtained, especially at high frequencies. In studies examining auditory brainstem responses (ABR) in OSAS patients, absolute latencies and interpeak latencies were often found to be prolonged compared to the control group. In the audiological evaluation of patients with OSAS symptoms and suspected hearing loss who apply to the audiology clinic, high-frequency pure tone audiometry, OAE and ABR measurements, as well as pure tone audiometry measurements, are thought to be important for early diagnosis and treatment.
