Type As (A shallow) suggests a stiffened middle ear system. Compliance There are three main types of tympanograms: A, B, and C. Type A tympanograms look like a teepee, and indicate a normal middle ear system, free of fluid or physiological anomalies which would prevent the admittance of sound from the middle ear into the cochlea. Figure 1 shows an example of a Type A tympanogram. Tympanometry is not reliable in infants younger than seven months because of the highly compliant ear canals of infants. Tympanogram tracings are classified as type A (normal), type B (flat, There are several tympanogram types, as proposed by Jerger: Type A. Type B. Type C. Type As. Type Ad. Tympanic membrane perforation. Before covering each below, please note that the classification of tympanogram types differs between clinics and audiologists.

Type B tympanogram may reveal (a) fluid in the middle ear, (b) perforation of the tympanic membrane or patent pressure equalization tube, or (c) a tumor in the middle ear. Type B tympanogram Type B (normal ear canal volume) usually suggests otitis media. Type B (small ear canal volume) may suggest that the ear canal is occluded with wax/debris or that the immittance probe Type B (large ear canal volume) suggests a patent pressure equalization tube or perforation of There are several tympanogram types, as proposed by Jerger: Type A.
