Objectives: We evaluated the effects of hyperlipidemia
on hearing function.
Patients and Methods: The study included 274
hyperlipidemic patients (176 females, 98 males; age
range 35 to 60 years) who manifested normal tympanic
membrane findings, no history of noise exposure,
and chronic systemic or ear diseases. Sixty
healthy subjects (36 females, 24 males) with normal
serum lipid levels were enrolled as controls. Subjects
who had elevated serum total cholesterol, triglyceride,
and very low density lipoprotein (VLDL) levels, and
normal lipid levels were divided into four groups and
their hearing functions were analysed with pure-tone
Results: Evaluation of all groups showed significantly
increased hearing levels at three frequencies in
female patients, and at six frequencies in male
patients (p<0.05). Significant increases in hearing levels
were observed both in females and males at 8000
Hz in three groups, at 6000 Hz in the VLDL group, and
in males at 2000 Hz in the total cholesterol and VLDL
groups (p<0.05). When both female and male patients
were evaluated together, the largest difference was
detected in the VLDL group at five frequencies.
Conclusion: The findings of our study suggest that
hyperlipidemia may have a role on the occurrence of
sensorineural hearing loss.
