What Is The Function Of The Middle Ear?
The middle ear known as the cochlea, is one of the common causes of hearing loss otosclerosis. Otosclerosis is a hereditary disease and after skipping several generations may occur.
The first stage of hearing sound waves along the outer ear channel reached, the membrane is titrestirmes. This vibration is located in the middle ear, the hammer, anvil, and stirrup to the inner ear through the bones called tiny fluid is transferred. The nerve endings in the inner ear, sound waves are converted to electrical energy transmitted to the auditory centers of the brain via the auditory nerve and hearing services.
Sound waves through the outer and middle ear to the inner problems that occur in the process of transferring kulaksivi “conductive hearing loss”. These types of losses in the hearing organs of the inner ear are fine, but sound waves can not reach the organs. Arising from the inner ear and the auditory nerve hearing loss, “hearing loss” is called. Otosclerosis is a disease that can affect the inner ear, which, in a combination of both types of losses are seen. This type of hearing losses “mixed type hearing loss” is called.
Noise Induced Hearing Loss
Bearing the auditory organs in the inner ear ossicles foci in the bone structure in the form of spongy-looking, new bone formations.
The disease is most frequently observed in the stirrup bone that transmits sound waves to the inner ear called the oval window is the region of the base portion of the location. Otosclerosis focus the stirrup (stapes) inner ear by preventing the vibration of the bone and disrupt the transmission of sound waves, as a result, a conductive hearing loss occurs.
These changes affect the auditory organs of the inner ear, “when called sensorineural hearing losses of cochlear otosclerosis occurs.
The type and degree of hearing loss in the high frequencies of the stapes eclipse (restriction of movement), the amount varies depending on the amount of the hearing organ of the inner ear is affected.
The Treatment Of Otosclerosis
Medical treatment: especially in rapidly progressive hearing loss at a young age, and identified a number of treatments are used to slow the progression of disease. However, there is no medical treatment for otosclerosis.
Surgical treatment: “Stapedectomy” restricted the movement with surgery, and the stirrup (stapes) inner ear, sound waves will transmit them to the bone instead of removing a prosthesis that is placed. Surgery can be performed under local or general anesthesia that 90-95% of successful results are obtained in the majority of the patients, almost all hearing loss can be corrected. With a slight hearing loss or auditory organs of the inner ear in patients with severe sensorineural hearing loss are severely affected, surgery is not recommended. All except that an obstacle to surgery in patients with otosclerosis usually it is suggested that unless there is a serious health issue on your side.
Dizziness may be for a few days after surgery. At the end of surgery surgical sponges are placed in the ear canal at the end of this period removed within 7-10 days and the patients can return to their normal lives.
The risks of surgery stapedectomy performed with appropriate surgical equipment and surgical techniques are quite low, although as with any Surgery, 1%, there is a risk of hearing loss. Apart from that, much more rarely, the formation of a hole in the eardrum, the facial nerve injury, ear infection, in the early period of the piston, can be traced to complications such as dislocation.
Hearing aids: every patient who can benefit from a hearing aid can also benefit from the surgery. Bilateral otosclerosis surgery, especially for patients who do not opt in parallel to the decreasing of the interior of hearing kulakfonksiyon stretched for failure are advised to use a hearing aid.
