Jerger tympanogram classification
WebHowever, the Jerger system is the most commonly used classification system for tympanograms. While other systems have been proposed, none are in as widespread of clinical use. A type A response suggests normal middle ear function, but it occurs in some otosclerotic ears, particularly in early stages. WebMay 14, 2007 · 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.
