Ear

    The cochlear implant or bionic ear with the function of the damaged inner ear is an electronic medical device used by those who experience severe hearing loss. There is a difference between cochlear implant and other hearing aids in terms of their functions as it plays the role of damaged parts of the inner ear. However, the hearing aids make the sound hear louder. The cochlear implant is very effective for the patients who experience a severe hearing problem, especially if it has been occurred recently and annoyed by buzz noise. It consists of two external and the internal components. The external piece is put back of the ear and the internal one implanted in the ear and skin surface through the surgery.

Cochlear Implant Components

    As it was mentioned above, the cochlear implant includes some implanted parts as well as the outer parts. The components work as followings:

    • The antenna receives the signals from the sound processor that is put behind the ear;
    • The receiver-stimulator manages the electrical signals into the ear;
    • The magnet holds the speech processor;
    • The wire with some electrodes is inserted into the cochlea.

    OR

    • Microphone gets the environmental sounds;
    • Sound processor that is put behind the ear processes the sounds;
    • The receiver-stimulator receives the sound signals and turns them into the electrical signals to the ear;
    • Electrodes are responsible for sending electrical pulses to the different auditory nerves.

    All parts must be placed in the right situation in order to work together, receive the sound, convey it to the auditory nerve, and then transmit it to the brain and finally provide hearing.

Cochlear Implant Advantages

    The cochlear implant helps the people with severe hearing loss to communicate properly. It is more suitable for infants and children learning the language skills. It also improves severe hearing loss as the cochlear implant can restore the damaged structure of the inner ear and stimulates the auditory nerves.

    Other advantages of cochlear implant includes the followings:

    • It works better than hearing aids;
    • It can even work in noisy environments, thus it helps the patient to communicate with several people in crowded places at the same time;
    • It progresses speaking and language skills;
    • It does well in the society and improves one’s confidence;
    • It enables the patient to talk and hear on the phone;
    • The patient will feel safer in the world as they can hear alarms, people calling out and approaching vehicles;
    • The patient will listen to music and enjoy it.

    Ear infection is caused by a bacterial or viral infection affecting the middle ear which causes pain, inflammation, and fluid buildup in the middle ear. An ear infection can be acute or chronic. Acute ear infection is painful but short in duration, while the pain in chronic ear infection occurs frequently. Chronic ear infection can sometimes cause damages to the middle and inner ears.

Causes of Ear Infection

    Ear infection occurs due to swelling or blockage of a part of ear called eustachian tube as well as fluid buildup in the middle ear. Eustachian tubes are small tubes that run from the ears to the back of the throat. In general, the causes of the Eustachian tube obstruction consist of:

    • sinus infections;
    • smoking;
    • changes in air pressure;
    • swollen or infected adenoids;
    • extra mucosa;
    • allergies,
    • getting a cold.

Risk Factors for Ear Infection

    Since the eustachian tubes are shorter and thinner in early ages, ear infection is most common in young children. Generally, the factors that increase the risk of ear infection include:

    • change in altitude;
    • smoking;
    • use of baby bottle in babies;
    • climate changes.

Symptoms of Middle Ear Infection

    • Fever;
    • feel of pain and pressure in ear;
    • ear discharges;
    • poor appetite in babies;
    • nausea or diarrhea;
    • temporary hearing loss.

The Ways of Diagnosing an Ear Infection

    The doctor uses a medical device called an otoscope to examine the ear. However, in acute ear infection, the doctor will check for the existence of any antibiotic-resistant bacteria by sampling the fluid inside the ear. In some cases, the doctor will use a CT scan to examine the affected areas of the ear. Hearing test is also prescribed for the patients with chronic ear infections.

The Ways of treating an Ear Infection

    In mild cases of ear infection, you can recover by observing the following therapies without visiting a physician:

    • warm compress;
    • use of painkillers and ear drops;
    • use of decongestants.

    If the above-mentioned treatments did not work it is recommended to visit a doctor. In the cases where ear infection does not resolve by usual methods, the doctor will use surgery. In most cases the fluid will drain out by the tubes inserted into the ear, and if the problem is due to adenoid enlargement a surgical operation will be done to remove the enlarged adenoid.
