Multifrequency tympanometry has emerged as a clinically feasible test with the advent of computer-controlled systems that can store and analyze complex immittance components at multiple probe tone frequencies. The theoretical basis for understanding multifrequency tympanometry has existed for years, but the diagnostic utility of data obtained at ...

Black (N = 63) and White (N = 74) infants, ages 6-13 months, were screened by tympanometry for signs of middle ear dysfunction. More White infants (57%) than Black (33%) failed initial screening (p less than .01). Retest of initial failures after a minimum 6-week interval showed an overall reduction in failure rates, but the significant (p less than ...

Multifrequency Tympanometry in Chinchillas
International Journal of Audiology, 1995Multifrequency tympanometry (MFT), using probe frequencies ranging from 226-2,000 Hz, was performed on normal chinchillas to obtain normative data against which to compare results from animals with middle ear pathology. A series of validating experiments was conducted to determine the effects of anatomical alterations of the middle ear on MFT.

Tympanometry and Acoustic Impedance
Acta Oto-Laryngologica, 1977In recordings of the acoustic impedance of the middle ear (tympanometry) the change in air pressure in the ear canal will mostly influence the capacitive component of the acoustic impedance. By choosing a probe tone frequency close to the resonance frequency of the middle ear, characteristic tympanometric patterns can be demonstrated in certain middle ...

Tympanometry in Normal Neonates
Journal of Speech, Language, and Hearing Research, 1979Acoustic conductance and susceptance tympanograms were obtained at 220 and 660 Hz in 34 neonates. The neonates were categorized into three age groups (8-24 hours, 24-60 hours, and 60-96 hours). Single-peaked, double-peaked, and monotoni-cally increasing tympanograms were found.

Pediatrics In Review, 1981
Tympanometry as a test of otologic status has the following attributes, uses, and advantages: (1) can be carried out simply, rapidly, and atraumatically, by appropriately trained nonprofessionals; (2) does not require, as does conventional audiometry, a sound-free environment; (3) is not influenced by the amount of cerumen ordinarily present in the ...

The 'fistula test' is performed when an abnormal opening between the vestibule and the middle ear cavity is suspected. The fistula is usually seen after stapedectomy, but may also occur after trauma to a normal ear when the round window membrane may rupture.

A flat tympanogram predicts a middle ear effusion in about 90% of cases. This paper describes how to perform tympanometry, some common problems when doing it and how to classify the curves in normal (type A), middle ear effusion (type B) or negative pressure (type C). The theoretical background of impedance audiometry is outlined. The stapedius reflex,

Tympanometry: Application and Interpretation
Annals of Otology, Rhinology & Laryngology, 1976The poor relationship between hearing loss and ear disease minimizes the effectiveness of audiometry as a technique for the identification of middle ear disorders. Tympanometry has been shown to be a highly sensitive technique for the identification of and differentiation between middle ear disorders.
