The use of 226 Hz tympanometry in neonates and infants has been controversial due to the large number of false negative responses for middle ear pathology. A review of the literature highlights several anatomical differences between this population and that of the adult, which is not recognized during interpretation of their tympanograms. The aim of the study was to document tympanometric changes in a single child using 226 Hz, 1000 Hz and sweep frequency probe tones until she was 6.5 months…

Tympanometry in infants with middle ear effusion having been identified using spiral computerized tomography.

Feasibility of 1000 Hz tympanometry in infants: tympanometric trace classification and choice of probe tone in relation to age.

Tympanometry in Infants: A Study of the Sensitivity and Specificity of 226-Hz and 1,000-Hz Probe Tones

The 1,000-Hz tone test has greater sensitivity and specificity for the correct identification of tympanometric curve changes, however, it is necessary to clarify the doubts that still exist regarding the use of this test frequency.

Tympanometry using 226 Hz is invalid below 21 weeks and 1000 Hz is the frequency of choice; both classification methods demonstrated significant differences between the two groups using the higher frequency probe tones, with Method 2 being the preferred system of classification.

High-frequency (1000 Hz) tympanometry in normal neonates.

The normative tympanometric data derived from this cohort may serve as a guide for detecting middle ear dysfunction in neonates.

A Preliminary Attempt to Profile Tympanometric Measures in Infants Using High Frequency Probe Tones

Ytm values were lesser or similar to other studies, TPP and Vea values had lower and narrow range, while TW were more than previous studies.

CHAPTER Tympanometry in Clinical Practice

These articles laid the foundation for the use of hardwalled calibration cavities and the term “equivalent volume of air”, compensation of ear-canal volume, and the selection of a single low-frequency probe tone, and set the precedent for measuring only the magnitude of complex acoustic immittance rather than both magnitude and phase angle.

Otoscopic findings indicated that external ear canal differences cannot completely account for tympanometric differences between young infants and adults.

Tympanometric detection of middle ear effusion in infants and young children.

Tympanometry is a simple, rapid, atraumatic, valid, and objective test, easily administered by paraprofessional personnel, that can result in improved detection of middle ear effusion and other middle ear abnormalities, and also appears to promote improvement in diagnostic acumen.

Otitis media in infancy: tympanometric findings.

Ninety-one normal infants were followed longitudinally for varying periods from November 1975 to April 1977 to assess the correlation between tympanometry and pneumatic otoscopy and to study the…

Middle ear function in neonates.

The finding of normal middle ear function in these neonates suggests that mucus is not commonly present and therefore not a factor in infants' response to sound.

Tympanometry in normal neonates.

Acoustic conductance and susceptance tympanograms were obtained at 220 and 660 Hz in 34 neonates and apparently were the result of previously identified interactions between static resistance and reactance values.

Multifrequency Tympanometry in Normal Adults

Based on testretest reliability and normal distribution characteristics, preferred methods for clinical estimation of resonant frequency were determined and Compensation for ear canal volume at +200 daPa was preferred over other compensation methods for estimation of middle ear resonant Frequency.

Impedance audiometry in a young population. The effect of age, sex, and tympanogram abnormalities.

In view of the potential influence of age, and, especially, minor middle ear abnormalities, on static compliance and acoustic reflex measures, these factors should be seriously considered when interpreting impedance audiometry findings in children.

Relative impedance measurements in young children.

A lack of information regarding relative impedance measurements in children limits the effective clinical use of this technique with this population, but this technique can be used in differentially diagnosing conductive hearing losses, 3 sensorineural losses with recruitment, 1,2,4,5 and, in certain instances, pseudohypacusis.
