In addition to classic otosclerosis, there is also a type known as cochlear otosclerosis. In patients with cochlear otosclerosis, calcification can occur at various points within the bony labyrinth of the inner ear. In these patients, hearing loss is not solely conductive; a mixed-type hearing loss, involving both conductive and sensorineural components, may be observed. Cochlear otosclerosis can be identified through audiometry. Due to the involvement of the sensorineural component, hearing aids are often the primary treatment option for these patients. However, some studies also suggest surgical interventions as a consideration prior to hearing aid use.
