Pneumatic otoscopy-a useful clinical skill worth developing
Tympanogram provides information about:
Type A - In a normal tympanogram (Type A) the peak pressure (TPP) should fall close to zero and the compliance should be between 0.3 and 1.5. Both should be within the normal range
Type B - there is a flat line due to reduced mobility of the TM.
Type C - shows a highly negative pressure in the middle ear, indicated by a negative TPP. The peak falls outside the normal range.
May indicate either partial effusion or Eustachian tube dysfunction
