The Esteem implanted hearing system is the first completely implanted system approved by the U.S. Food and Drug Administration for adults with moderate-to-severe sensorineural hearing loss, a permanent lack of hearing, the agency said Wednesday.
Sensorineural hearing loss can be caused by genetic factors or by inner-ear damage resulting from causes such as loud noise, a viral infection or general aging, the FDA said in a news release.
Three implanted components comprise the system: a sound processor, a sensor and a driver that converts electrical signals transmitted by the sound processor to the inner ear, which perceives them as sounds.
The most severe adverse reactions resulted from the implant surgery, and included facial paralysis (7 percent) and taste disturbance (42 percent). Most of these reactions resolved during the one-year clinical testing of the device, the agency said.
The device is produced by Minnesota-based Envoy Medical Corp. As a condition of approval, Envoy must conduct longer-term studies of the device’s safety and effectiveness, the FDA said.

- (HealthDay News) — While hearing loss may be present from birth or come on gradually as a person gets older, it isn’t always permanent.
The U.S. National Library of Medicine says temporary hearing loss may be caused by:
- A blockage in the Eustachian tube.
- Allergies.
- Wax buildup inside the ear.
- An ear infection, or an object lodged inside the ear.
- A head injury.
- A perforated or scarred eardrum.
- A reaction to certain medications, such as aminoglycosides, chloroquine, or quinidine.
An ear tube is surgically implanted in a child’s ear to help drain fluid that builds up behind the eardrum, says the U.S. National Library of Medicine.
When fluid builds up in the ear and stays there for a long period, it can cause hearing loss. Ear tubes may also be inserted when a child has frequent ear infections that can’t be prevented with less invasive treatments.
Ear tube insertion is performed under general anesthesia. The surgeon first makes a small incision in the eardrum. The fluid is suctioned out, then a small tube is inserted in the eardrum. Now, air can flow through the ear and fluid can drain from the middle ear, the agency says.
Ear tube surgery is usually an outpatient procedure, so the child can go home the same day. The following day, most children can resume normal activities. The surgical incision usually heals on its own, without stitches. The ear tube commonly falls out after about 14 months.

It is estimated that approximately 90 percent of people with tinnitus have some degree of hearing loss. Therefore, hearing tests are essential before a proper diagnosis of tinnitus may be determined.
Tinnitus may be a symptom of a variety of ear disorders or other medical conditions. Usually it is difficult for doctors to determine the exact cause of tinnitus.
Damage to your inner ear from disease, blockage, noise or lack of nutrients will cause hearing loss. Poor blood flow, fluid from an infection and other factors can cause the tiny hair follicles in your inner ear to die.
The sad truth is most doctors will never know why your hearing went bad. In most cases they just can’t explain it.
Day by day the cells in your inner ear are dying, don’t wait until your hearing is gone forever.
There are natural herbs and supplements you can take that can greatly improve and even restore your hearing. The tiny hair follicles in your inner ear can greatly improve with increased blood flow to them.
You may already know that free radicals have been show to cause disease. They are highly reactive molecules that disrupt the structure of normal cellular components like the ones in your inner ear.
One of the activities of free radicals is to destroy cochlear hair cells, which transmit acoustic information to the auditory nerve. Using the proper antioxidant’s you can fight off these free radicals. Click here to find out more.
