There are 3 main different types of hearing loss: Conductive hearing loss, Sensorineural hearing loss, and Mixed hearing loss. The type of hearing loss depends on which part of the ear is being affected. A comprehensive hearing evaluation must be completed in order to accurately determine the type and severity of hearing loss and to make appropriate recommendations for hearing loss treatment.
Conductive Hearing Loss
Conductive hearing loss causes problems to sounds that are transmitted through the outer and middle ear. This type of hearing loss is probably the most common and can be caused by:
- Ear infection
- Blockage in the ear canal (Ear wax, tumors, & any other foreign bodies in the ear)
- Fluid in the middle ear (Maybe from a cold or allergies)
- A hole in the eardrum (Caused either by trauma to the ear or an ear disease)
- Blockage of the ear canal such as ear wax or a foreign body
- A hole in the tympanic membrane (eardrum) caused either by trauma or disease
- Damage to the three tiny bones in the middle ear a.k.a. the ossicular chain (Caused either by trauma to the ear or an ear disease)
- Abnormal bone growth in the middle ear a.k.a. Otosclerosis
Sensorineural Hearing Loss
Sensorineural hearing loss affects the inner ear or the central auditory system which includes the auditory nerve and the cochlea, which is the organ of hearing. Sensorineural hearing loss can occur when the hair cells, neural fibers, or their connections to the auditory nerve are damaged or do not function properly. Common causes of Sensorineural hearing loss include:
- Exposure to loud noise
- Certain types of infection
- Age-related hearing loss problems a.k.a. presbycusis
- Head trauma or physical damage to the ear
- Malformation of the inner ear
- Inner ear disorders and diseases including: Meniere’s disease and Autoimmune inner ear disease
- Kidney disease
- Cancer treatments like chemotherapy and radiation treatment
Mixed Hearing Loss
Mixed hearing loss refers to a combination of Conductive and Sensorineural hearing loss. This means that there may be damage in the inner ear and the outer or middle ear.
