Volume of voice remains normal because inner ear and auditory nerve are intact.Inner ear, cochlear, or auditory nerve pathology that impairs neuronal transmission to the brain.External or middle ear pathology that disrupts conduction of sound into the inner ear.Traumatic (e.g., noise-induced hearing loss).Otitis media with or without serous effusion.Treatment depends on the underlying etiology and can include hearing aids or cochlear implants for irreversible conductive or sensorineural hearing loss, respectively. This may be followed by otoscopy, audiometry, laboratory tests, or imaging, depending on the underlying suspected cause.
Subsequently, tuning fork tests should be performed to differentiate between conductive and sensorineural hearing loss. Patients with a complaint of hearing loss should be screened with techniques such as the whispered voice or finger rub tests. Sometimes hearing loss can have both conductive and sensorineural components, which is referred to as mixed hearing loss. Sensorineural hearing loss, on the other hand, occurs due to dysfunction of the inner ear or auditory nerve, which prevents neuronal transmission to the brain.
Conductive hearing loss typically occurs due to dysfunction of the outer or middle ear, which prevents transmission of sound waves from reaching the inner ear. Hearing loss can be defined based on the general type of hearing loss (conductive or sensorineural) and the location of the dysfunction.
