middle ear

The middle ear is defined as a cavity located behind the tympanic membrane, where it is connected to the pharynx on the edge of the Eustachian tube, which is the channel responsible for equalizing atmospheric pressure on the tympanic membrane. And passengers, in addition to balancing the pressure inside the ear with the external atmospheric pressure, and in this article we will introduce you to the greatness of the passengers.

Where is the stirrup bone

The stirrup bone is known as a thin bone in the middle ear, which is small and its function is to transmit vibrations directly to the cochlea. It is famous for being the smallest bone in the human skeleton. It is called stipes in Latin, due to its shape. It is one of the three hearing bones located in the middle ear cavity, and its function is to conduct sound to the anvil, which passes through it to the hammer that connects to the tympanic membrane of the ear, and it stabilizes the other bones; Because it is connected to it, in addition to the fact that it delivers the raw material, which is the sound, to it, to help it perform its function. Therefore, most hearing problems occur as a result of a defect in the bone of the stirrup, as it may be subjected to calcification, which reduces its movement, and becomes unable to transmit Acoustic vibrations to the inner ear, this condition is known as stirrup bone sclerosis.

Stiffness of the stirrup bone

Stubborn stiffness factors

  • A disorder that leads to abnormal growth in the bones of the middle ear, as it becomes spongy, thus losing its ability to distinguish sounds or hear.
  • Gender, which affects women more than men.
  • The presence of a genetic factor.
  • Imbalance of the proportion of fluorine in the body.

Symptoms of stirrup bone sclerosis

  • Hearing loss, and it usually appears gradually in ages ranging from 20-40 years, knowing that it affects females more than men, and it develops gradually, and in most cases it affects the ears.
  • Tinnitus.
  • Feeling lightheaded or dizzy.

Methods for diagnosing stapedius osteochondrosis

  • Otoscopy with a microscope.
  • Audiological examination, which usually shows conductive hearing loss.
  • Tabla layout.
  • Computerized tomography of the ear.
  • Magnetic resonance imaging.
  • Radiography.

Stubborn sclerosis treatment

The treatment is surgery, where the operation is carried out through the ear canal after the whole body is anesthetized, then the stirrup bone is removed, and replaced with a small artificial bone, and it is possible to install loudspeakers, in addition to treating the underlying cause, such as treating the problem of fluorine imbalance in the body.
