Reduced mobility of the tympanic membrane caused by a stiffened middle ear system can cause a shallow peak on the tympanogram, called a Type A s tympanogram. Type A tympanogram. Figure 1 shows what a type A tympanogram looks like: Figure 1: Type A tympanogram. Type A tympanograms exhibit the following characteristics: Sharp peak; Middle ear pressure between -99 to +50 mmH 2 O; Static compliance between 0.3-1.6 cc in adults; Static compliance between 0.2-0.9 cc in children 3-5 years of age A normal tympanogram (left) is labelled Type A. There is a normal pressure in the middle ear with normal mobility of the eardrum and ossicles.

1. Ear Hear. 1984 Sep-Oct;5(5):268-80. Tympanometry. Shanks JE. The basic principles essential for interpreting two-component, multiple frequency tympanograms first are reviewed. Tympanometry is part of comprehensive ear health and hearing screening for children. Screening includes otoscopy and may also include video otoscopy and/or audiometry.

Type C Tympanometry showed significant negative middle ear pressure in the presence of normal static Tympanometry measures the mobility of the tympanic membrane and the middle ear pressure, but it does not measure perceptual hearing. The results from tympanometry are plotted as a graph called a tympanogram (eSlide 50.5). There are three main types of tympanograms: A, B, and C. A Type A tympanogram indicates normal middle ear status. in this video different types of tympanograms i.e. A , As , Ad , B and C are disscussed. The Questions that How they are made?

In most cases of otosclerosis, though there is a middle ear stiffness, the tympanometric findings with traditional tympanometry show normal compliance, which is not expected in stiffness of the middle ear. Tympanometry is a hearing test used to measure the function of the middle ear and eardrum. It has proved to be extremely helpful in diagnosing hearing problems and finding adequate medical solutions for hearing loss.
