What happens if the cochlea is damaged?
Cochlear Damage means that all or part of your inner ear has been hurt. Damage to the cochlea typically causes permanent hearing loss. This is called sensorineural hearing loss (SNHL). Noise-induced hearing loss, or NIHL, occurs when your ears are exposed to overly loud sounds.
What causes cochlear abnormality?
Many things can cause SNHL, or cochlear damage, including loud or extended noise exposure, certain powerful antibiotics, men- ingitis, Meniere’s disease, acoustic tumors, and even the natural decline in age can cause hearing loss.
How do you know if your cochlea is damaged?
Symptoms may include:
- Some sounds seem overly loud in one ear.
- You have problems following conversations when two or more people are talking.
- You have problems hearing in noisy areas.
- It is easier to hear men’s voices than women’s voices.
- It is hard to tell high-pitched sounds (such as “s” or “th”) from one another.
What are some disorders of the inner ear?
Introduction: Disorders of the inner ear can cause hearing loss, tinnitus, vertigo and imbalance. Hearing loss can be conductive, sensorineural, or mixed; conductive hearing loss arises from the ear canal or middle ear, while sensorineural hearing loss arises from the inner ear or auditory nerve.
Can cochlea be repaired?
Summary: Hearing loss due to cochlear damage may be repaired by transplanting human umbilical cord hematopoietic stem cells. “Our findings show dramatic repair of damage with surprisingly few human-derived cells having migrated to the cochlea,” said Roberto P. Revoltella, MD, PhD, lead author of the study.
How do you repair a damaged cochlea?
A cochlear implant is a surgery for adults, and, more commonly, children who have no, or very little, residual hearing. It works by bypassing a severely damaged cochlea to send electrical impulses to the hearing nerves that can be translated by the brain as meaningful sound.
Can tinnitus be cured?
Many times, tinnitus can’t be cured. But there are treatments that can help make your symptoms less noticeable. Your doctor may suggest using an electronic device to suppress the noise.
What is the most common inner ear disorder?
- Ear infections are the most common illness in infants and young children.
- Tinnitus, a roaring in your ears, can be the result of loud noises, medicines or a variety of other causes.
- Meniere’s disease may be the result of fluid problems in your inner ear; its symptoms include tinnitus and dizziness.
How serious is a cochlear implant?
While cochlear implant surgery is extremely secure, any procedure carries risks. Possible complications include: Facial Nerve damage Dizziness or balance problems. Hearing loss Ringing in your ears (tinnitus) Fluid leaks around the brain. Meningitis, an infection of the membranes that surround the brain. It’s an uncommon but severe side effect.

What are the side effects associated with cochlear implants?
Bleeding and swelling at the site of the implant
What is cochlea disorder?
Cochlear blood flow is a function of cochlear perfusion pressure, which is calculated as the difference between mean arterial blood pressure and inner ear fluid pressure. Many otologic disorders such as noise-induced hearing loss, endolymphatic hydrops and presbycusis are suspected of being related to alterations in cochlear blood flow.
