The Correlation Between Petrous Part of the Temporal Bone Density and the Internal Auditory Canal Diameter in Sensorineural Hearing Loss Patients with Chronic Renal Failure

Patients with chronic renal failure often suffer from hearing loss and the most common cause is sensorineural hearing loss. Sensorineural hearing loss can be caused by cochlear otosclerosis with early symptoms such as decreased petrous part of the temporal bone density due to narrowing of the internal auditory canal. Finding a correlation between the petrous part of the temporal bone density and the anteroposterior diameter of the internal auditory canal in sensorineural hearing loss in patients with chronic renal failure. An observational analytic, cross-sectional study, using a consecutive sampling technique. The petrous part of the temporal bone density decreased in patients with chronic renal failure. The anteroposterior diameter of the internal auditory canal remained normal, there was no association with sensorineural loss. There is a significant correlation between the petrous part of the temporal bone density and sensorineural hearing loss in patients with chronic renal failure. High-resolution CT scans of the mastoid can assist clinicians in determining cochlear otosclerosis and the subsequent detection of the early presence of sensorineural hearing loss.
