How do you interpret tympanogram results?
How do you read a tympanogram report? A tympanogram will show the results of one eardrum at a time. An “L” on the tympanogram indicates the left eardrum; an “R” indicates the right eardrum. A clinician will mainly look at the peak of each graph.
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.
What causes a type B tympanogram?
Type “B” tympanogram pattern is not diagnostic of middle ear effusion. The same pattern can also be caused when the probe tip hole is occluded by cerumen or by contact with the canal wall. A type “B” pattern will also occur when there is a perforation in the TM, including a tympanostomy tube.
What are normal tympanogram results?
Middle ear pressure values ranging from +50 daPa to –200 daPa for children, and +50 daPa to –50 daPa for adults is generally considered normal. The compliance of the middle ear system is a measure of how well the system responds to sound. This is shown by the height of the “peak”.
What causes a Type C tympanogram?
Finally, a Type C tympanogram indicates a significantly negative peak pressure, which is possibly caused by Eustachian tube dysfunction or a developing or resolving middle ear infection.
What are Immittance measures?
Immittance Testing Immittance Audiometry consists of three procedures: tympanometry, acoustic reflex testing and reflex decay testing. These tests measure alterations and fluctuations of the eardrum (tympanic membrane) and the integrity of the nervous system in response to stimuli.
What color should the tympanic membrane be?
pearly grey
1) Color/shape-pearly grey, shiny, translucent, with no bulging or retraction. 2) Consistency – smooth.

Why is my eardrum purple?
Abstract. The “blue ear drum” generally refers to a condition in which blood or blood products are found in the middle ear. After all possible causes for hemotympanum, including blood dyscrasias and trauma are searched for and ruled out, the patient may have chronic serous otitis media accompanied by bloody effusion.
What does negative pressure on a tympanogram mean?
Tympanogram tracings are classified as type A (normal), type B (flat, clearly abnormal), and type C (indicating a significantly negative pressure in the middle ear, possibly indicative of pathology).
