Which type of hearing loss is caused by abnormalities of both the inner and outer/middle ear?

Mixed hearing loss is characterized by abnormalities in both the inner ear, which is responsible for sensory function, and the outer or middle ear, which is involved in sound conduction. This type of hearing loss results from issues such as damage to the hair cells in the cochlea (inner ear) that affects the sensory response to sound, along with problems like fluid in the middle ear or eardrum perforation that impede sound transmission.

Each component of the auditory system plays a crucial role in how sound is perceived and processed; hence, when damage occurs in both regions, the individual experiences a combination of conductive (related to the outer/middle ear) and sensorineural (involvement of the inner ear) hearing loss. This dual impairment can make diagnosis and treatment more complex, necessitating a comprehensive approach to management such as a combination of medical treatment and hearing aids.

Understanding this combination is key for hearing specialists in order to provide effective intervention strategies tailored to the individual's specific type of hearing loss.
