Objectives/hypothesis: Presbycusis is the most prevalent cause of hearing-loss in the older, but pathogenesis is not well-know. The premise of this study is that hyperlipemia increase risk of age-related hearing-loss. Patients and methods: 180 patient more than 65 years-old were studied. All patients had bilateral hearing-loss and no renal, neurological, thyriod or middle-ear pathology. We explored serum levels of cholesterol, HDL, LDL and triglycerides. We performed tonal audimetry in all patients. Results: The 71% of patients has hypercholesteremia and the higest serum levels were detected in 65-69 yearsold men (mean media 5,27). Patients with hypercholesteremia had worse hearing-loss than patients with normal lipid serum levels (p < .05). Conclusions: Our study sugest that hypercholesteremia are associated to age-related hearing-loss, possibly by an atherosclerosis mechanism.

Keywords : Age-related hearing-loss; presbycusis; hypercholesteremia; atherosclerosis.
