Obstructive Sleep Apnea (OSA), a condition characterized by the collapse of the upper airway during sleep has been extensively linked to diabetes, cardiovascular diseases and mortality. However, its possible association with hearing disorders has not been widely investigated. This project will investigate the occurrence of OSA with hearing dysfunctions and the potential benefit of Continuous Positive Airway Pressure (CPAP) therapy. Not only would this study increase the awareness of concurrent OSA and hearing dysfunction, CPAP could be used as an alternative non-invasive therapy for patients with hearing disorders.
