What causes 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.
How do you interpret tympanometry results?
To interpret tympanometry tests, you’ll mainly look at the peak of the graph. Tympanogram results are categorized as either a Type A, Type B, or Type C. Type A results are considered normal. Type B results are considered abnormal (or “flat”) and often mean the patient has fluid in the middle ear.
