The variables containing the numeric data for these latter measurements (AUXTMEPR, AUXTMEPL, AUXTPVR, AUXTPVL, AUXTCOMR, AUXTCOML, AUXTWIDR, and AUXTWIDL) are located in the separately released NHANES 2001-2002 Audiometric Examination data file (AUX_B). Again, 2012-10-16 AUXTWIDR - Tympanometric width, right ear Variable Name: AUXTWIDR SAS Label: Tympanometric width, right ear English Text: Tympanometric width, right ear Target: Both males and females 12 YEARS - 19 YEARS Hard Edits: 0.0000 to 500.0000 Tympanometric data were gathered on a clinical immittance machine, the Virtual 310 equipped with a high-frequency option. Two of the parameters, static admittance and tympanometric width, were measured automatically at a standard 226 Hz frequency. The remaining two parameters, Tympanometric Width. Evaluation of tympanometric width, often termed tympanometric gradient, Tympanometric width is a measure of the width of the tympanogram measured at half of the static admittance from the peak to the admittance at +200 daPa.

Four of the parameters-static admittance (SA), tympanometric width (TW), tympanometric peak pressure (TPP), and ear-canal volume (ECV)-were measured automatically at a standard 226 Hz frequency. The remaining two parameters-resonant frequency (RF) and SA up to 1,200 Hz-were measured by multifrequency, multicomponent tympanometry, using a mathematical approach.

TPP: tympanometric peak pressure from admittance tympanogram. 9 Aug 2010 Although tympanometric width has been investigated in infants and neonates The tympanometric peak pressure represents a less useful  acoustic admittance. SD: standard deviation. TPP: tympanometric peak pressure.

For static admittance, the mean for all ages combined was 0.45 mmhos (SD = 0.19), with a 90 percent range of 0.2 mmhos to 0.7 mmhos. Tympanometric width for all ages com-bined was 148 daPa (SD = 40), with a 90 percent range of 102 daPa to 204 daPa. Age and gender effects were studied using Normative values for static acoustic admittance (SAA), tympanometric peak pressure (TPP) and tympanometric width (TW) were calculated.

The diagnostic value of tympanometric width in identifying middle ear disorders @article{Zakaria2020TheDV, title={The diagnostic value of tympanometric width in identifying middle ear disorders}, author={M. Zakaria and Maziah Romli and W. Mohamad and M. Awang and N. Wahab}, journal={Indian Journal of Otology}, … Normative values for peak, compensated static acoustic admittance (Peak Ytm), acoustic equivalent volume (Vea), and tympanometric width (TW) were determined for 102 young adults with normal hearing. Relative to the Margolis and Heller normative values, … Design: Nine tympanometric measures were examined in 68 normal ears and 14 ears with surgically confirmed otosclerosis. No subjects in either group had a history of head trauma or otoscopic evidence of eardrum abnormalities. Two parameters, static admittance and tympanometric width, were derived from standard low-frequency tympanometry and two regardless of the test condition. Tympanometric width was examined only with a low-frequency probe tone, and test-retest reliability for this variable was not found to be as high as static acoustic admittance or acoustic susceptance. In addition to test-retest reliability … tympanometric width: Abbreviation Variation Long Form Variation Pair(Abbreviation/Long Form) Variation No. Year Title Co-occurring Abbreviation; 1 : 2021: Evaluation of Middle Ear Function by Tympanometry and the Influence of Lower Barometric Pressure at High Altitude.

Tympanometry is a technique used to look at the function of the middle ear. Design: Nine tympanometric measures were examined in 68 normal ears and 14 ears with surgically confirmed otosclerosis. No subjects in either group had a history of head trauma or otoscopic evidence of eardrum abnormalities. Two parameters, static admittance and tympanometric width, were derived from standard low-frequency tympanometry and two 1999-11-01 · Significant correlations between tympanometric width and MRI measures of effusion were documented, confirming the high predictive value of the tympanometric width for diagnosing the presence and quantity of middle ear effusion. (Otolaryngol Head Neck Surg 1999;121:523-7.) Posts about Tympanometric width written by Callier Library. The goal of this study was to compare the performance of two middle ear analyzer systems on a range of tympanometric parameters, including both the standard 226 Hz and multi-frequency tympanometric measures.
