What is a pneumatic otoscopy, and how does it work?
Pneumatic otoscopy is an ear examination that evaluates the movement of the eardrum in response to pressure changes. In a healthy ear, the eardrum moves in reaction to pressure. Immobility can be caused by a variety of factors, including:
- The ear is full of fluid.
- Perforation is a term used to describe the process of (hole).
- Tympanosclerosis is a condition that affects the ears (scarring of the eardrum).
- Infections of the middle ear.
The following are some of the benefits of a pneumatic otoscopy:
- Best among all the available method of ear examination.
- Other ways are more expensive.
- With the right instruction, it’s simple to do.
- Tests that are quick and painless.
- Otoscopes are inexpensive and readily accessible.
A pneumatic otoscopy is a valuable tool for examining middle ear disorders.
Our ear is divided into three sections. Each component serves a critical purpose:
When the sound is collected and directed by the outer ear (pinna and ear canal), the eardrum vibrates. The vibrations are amplified and sent to the inner ear through the middle ear (tympanic membrane, ossicles, mastoid, and eustachian tube).
The inner ear (cochlea) then converts vibrations into electrical impulses. After that it is sent to the brain.
The following items are required for a pneumatic otoscopy:
Otoscopes using a pneumatic tube: The ear canal and eardrums are visualized with these devices. Otoscopes is charged with a bright bulb.
Specula for the ears:
When should a pneumatic otoscopy be performed?
The following problems can be diagnosed with a pneumatic otoscopy:
Acute otitis media (inflammation of the middle ear) (a painful type of ear infection)
Medial otitis with effusion (collection of thick fluid behind the eardrum)
Retraction of the tympanic membrane (retraction of the eardrum)
Fistula test or Hennebert’s sign (a test done to identify the root cause of repeated vertigo)
Brown’s signature (a test done to reveal a reddish-bluish pulsatile mass behind the eardrum)
What are the risks associated with a pneumatic otoscopy?
During the process, you could feel some discomfort. The following are some of the less common otoscopy complications:
Ossicular discontinuity: It’s when the three middle ear bones lose their usual alignment.
Hearing loss caused by injury to the inner ear or the nerve connecting the ear to the brain is known as sensorineural deafness.
