tympanometry


Also found in: Wikipedia.

tympanometry

 [tim″pah-nom´ĕ-tre]
indirect measurement of the compliance (mobility) and impedance of the tympanic membrane and ossicles of the middle ear; it is done by subjecting the external acoustic meatus to positive, normal, and negative air pressure and monitoring the resultant sound energy flow. See also tympanogram (def. 2).

tym·pa·nom·et·ry

(tim'pă-nom'ĕ-trē),
A technique that measures immittance of the middle ear at various levels of air pressure; helpful in the diagnosis of middle ear effusion, eustachian tube function, and otitis media.

tym·pa·nom·et·ry

(tim'pă-nom'ĕ-trē)
Measurement of the pressure compliance function of the eardrum using an immitance instrument (e.g., an audiometer).

tympanometry

Measurement of the air pressure in the middle ear and of the stiffness of movement of the eardrum and the AUDITORY OSSICLES. Tympanometry may be used as part of the assessment of hearing defect.

5) were as follows: 75% (n = 18/24) reported using both distortion product otoacoustic emmissions (DPOAE) and AABR, and 13 of them indicated the additional use of at least one outer-ear or middle-ear screening measure, such as otoscopy, high-frequency (1 000 Hz probe tone) and acoustic reflex screening; 21% (n = 5/24) reported using DPOAE and AABR, with no use of outer and middle ear screening measures; 21% (n = 5/24) reported using either DPOAE or AABR; and 1 participant reported using only otoscopy and tympanometry for NIHS.

In addition, patients with pathologic tympanometry findings and those with known chronic ear and mastoid process inflammation, hearing amplified subjects and those with otosclerosis, tympanosclerosis and acute tinnitus persisting for up to three months, as well as facial nerve disorders of specific etiology and those associated with neurologic disorders were not considered eligible for inclusion in the study.
