What does Otoscopy measure?
The otoscope exam helps to assess the condition of the external auditory canal (EAC), tympanic membrane (TM), and the middle ear. Early stages of otologic diseases can be present in the absence of complaints such as ear pain, ear fullness, and hearing loss.
What do you look for in an Otoscopy?
Typical findings on otoscopy include a bulging red, yellow or cloudy tympanic membrane with an associated air-fluid level behind the membrane. There may also be discharge in the auditory canal if the tympanic membrane has perforated.
How helpful is pneumatic Otoscopy in improving diagnostic accuracy?
The mean absolute increase from static to pneumatic performance was 15% improve- ment in total score, 12% improvement in sensitivity (accurate detection of ears with MEE), and 18% im- provement in specificity (accurate detection of effu- sion-free ears).
How is a otoscope used for diagnosis?
An otoscope is a tool which shines a beam of light to help visualize and examine the condition of the ear canal and eardrum. Examining the ear can reveal the cause of symptoms such as an earache, the ear feeling full, or hearing loss.
How is pneumatic Otoscopy used?
Gently squeeze the bulb on the otoscope to create positive pressure on the tympanic membrane and observe the degree of tympanic membrane mobility. Release the bulb to create negative pressure on the tympanic membrane and observe the degree of tympanic membrane mobility.
How do you perform a pneumatic Otoscopy?
What causes otitis media with effusion?
Causes. Otitis media with effusion is usually a result of poor function of the eustachian tube, the canal that links the middle ear with the throat area. The eustachian tube helps to equalize the pressure between the air around you and the middle ear.
Why do I need a pneumatic otoscopy for my middle ear?
The normal tympanic membrane moves in response to pressure. Immobility may be due to fluid in the middle ear, a perforation, or tympanosclerosis, among other reasons.The detection of middle ear effusion by pneumatic otoscopy is key in establishing the diagnosis of otitis media with effusion (OME).
Can a pneumatic otoscopy be painful for AOM?
Pneumatic otoscopy can be painful in children with AOM. It is not necessary in children with bulging tympanic membranes because all bulging tympanic membranes have decreased or absent mobility. A bulging tympanic membrane is the hallmark of AOM and differentiates AOM from otitis media with effusion (OME).
Who was the first to use a pneumatic otoscope?
Siegle first described the principles and use of pneumatic otoscopy for detecting effusion more than a century ago. This was popularized by Politzer in 1909. [ 21] Apart from the technical difficulty of obtaining an adequate seal, no contraindications exist for pneumatic otoscopy.
Are there any contraindications for pneumatic otoscopy?
Contraindications. Apart from the technical difficulty of obtaining an adequate seal, no contraindications exist for pneumatic otoscopy. Great care and small pressure changes should be employed in patients with a very thin tympanic membrane or segment to avoid discomfort or perforation.
