Sensorineural Hearing Loss is hearing loss that is a result of damage to the inner ear. Involving the delicate mechanisms and neural connections, the inner ear is composed of various delicate components, most of which do not have the capacity to repair or regenerate themselves if damaged. Injury to the inner ear often results in some degree of permanent hearing damage. Often sensorineural hearing loss is gradual, as lasting damage to the inner ear accrues and compounds over time. The inability of the inner ear to rebound from injury is part of what makes sensorineural hearing loss the most common type of hearing loss, accounting for 9 out of 10 reported hearing loss cases.
