Hearing Aid Care
Hearing is an anatomic function in which the external ear collects sounds and sends them to the eardrum, or tympanic membrane, which separates the outer ear from the inner ear. Sounds are then interpreted by the brain, which processes the appropriate response. The three primary bones involved in sound transmission are the malleus (hammer), incus (anvil), and stapes (stirrup).
Causes of hearing loss include chronic ear infections, trauma (pressure changes), age changes (presbycusis), and neuromas on the acoustic nerve. Certain drugs may also contribute to hearing loss or degradation, including aspirin, naproxen, and ketorolac.
Many people—no matter what their age—are embarrassed to admit to hearing loss. They may find themselves nodding agreement with something someone said, even if they’re unsure what was said. Or they may not pay attention when someone is talking, unintentionally offending the speaker. Patients who have hearing loss may be able to use a hearing aid to help regain some of the lost hearing. Several types of hearing aids are available:
The “open behind the ear” aid is a slim tube inserted into the ear canal. It’s best for mild to moderate high-frequency hearing losses.
The “behind the ear” aid amplifies the sound from a customized ear mold that’s placed in the ear canal. These aids are used for mild to moderate hearing loss.
The “full shell” aid is custom-made and fits on the outer ear. It’s used for mild to severe loss.
The “half shell” models are also custom-made and provide optimal performance with greater comfort. They’re used for mild to severe losses.
The “canal” aid fits inside the external ear canal and is used for mild to moderately severe loss.
The “mini-canal” fits almost completely inside the external ear canal and is appropriate for mild to moderately severe hearing loss.
The “completely in the canal” model fits deeply within the external ear canal. This type decreases wind noise, has less feedback, and provides a more natural sound. Individuals with mild to moderately severe hearing loss can benefit from this type of aid.
Patients generally wear hearing aids during the day only. At night and at times of rest, the hearing aid is usually removed. Because of the fragile nature of the hearing aid, it’s important to clean it properly and carefully to avoid damage.
