The Significant Correlation Between the Density of the Cochlea Otic Capsule and Spine in Hearing Loss Patients

Osteoporosis and osteopenia are systemic disorders that affect all bones. Osteoporosis in the ear bone and cochlea otic capsule contribute to the occurrence of conduction and sensorineural deaf. The osteoporosis prevalence in RSSA is 38%; meanwhile hearing interference in osteoporosis patients is 66.67%. The femur and spine DXA are the golden standard to calculate the bone mineral density. The temporal bone density can be measured with CT scan using the Hounsfield Unit units. There is a hypothesis that the femur bone mass density can illustrate the temporal bone density. This study aimed to analyzes the correlation between the density of the cochlea otic capsule and the ear bone towards the femur and spine density in patients with reduction in bone density. This was a cross-sectional observational type analytic retrospective study analyzing 30 samples of patients with a reduction in bone density that have HRCT Mastoid examination results during 2017 at RSSA Malang’s osteoporosis polyclinic. From 30 samples, most were female with an age range of 51–60 years old. The average femur, spine, ear bone and cochlea otic capsule of the osteoporosis group was lower than the osteopenia group. The spine density was significantly correlated with the otic capsule density. There was a positive significant correlation between the spine density towards the otic capsule density. The lower the spine density, the lower the otic capsule became.
