middle ear
The middle ear is defined as a cavity located behind the drum. The pharynx is connected to the pharynx of the Astacus channel, the channel responsible for equalizing the air pressure on the membrane of the drum. It also contains three magnets that contribute to the transmission of oscillations from the eardrum to the inner cochlea: the hammer, , And passengers, in addition to the balance of pressure inside the ear with external pressure, and in this article we will inform you of the greatness of passengers.
Where is the grandeur of the passengers?
The greatness of the passengers is known as a small bone in the middle ear, a small function of transmitting the oscilloscope to the shell directly, and is known as the smallest bones of the skeleton of the human, and called the name of Stipes in Latin, because of the form, the passengers part of the saddle that is placed on the back of the Persians, It is one of the three hearing aids in the middle ear cavity. Its function is to connect the sound to the anvil, through which it passes through the hammer that connects to the ear drum, To help him On the performance of its function, so most of the lack of hearing problems occur as a result of a defect that in the greatness of the passengers, as it may be exposed to calcification, which reduces the movement, becomes unable to transmit sound vibrations to the inner ear, known this case as the hardening of the greatness of the passengers.
Stiffness of the grandeur of the passengers
Factors that stiffen the bone of the passengers
- A disorder that leads to abnormal growth in the bones of the middle ear, where it becomes spongy, which loses its ability to distinguish sounds, or hearing.
- Sex, where it affects women more than males.
- The presence of a genetic factor.
- Disruption of the element of fluorine in the body.
Symptoms of stiffness of the bone of the passengers
- Hearing loss, usually manifested gradually in the ages of 20-40 years, it affects females more than men, it develops gradually, and in most cases affects the ears.
- Tinnitus.
- Feeling dizzy, dizzy.
Methods of diagnosis of stiffness of passengers
- Microscopy of the ear.
- The auditory examination, which usually shows a hearing impairment.
- Drum layout.
- Computed tomography of the ear.
- Magnetic Resonance Imaging.
- Radiography.
Treatment of stiffness of passengers
Treatment is surgery, where the process is done through the ear canal after the body completely numb, then remove the greatness of the passengers, and replace it with a small industrial Bazimh, it is possible to install speakers glass sound, as well as to treat the underlying cause, such as the treatment of the problem of disruption of fluoride in the body.
