The study investigated the effect of ear canal pressure and age on wideband absorbance (WBA) in healthy young infants. Design: Using a cross-sectional design, WBA at 0.25 to 8?kHz was obtained from infants as the ear canal pressure was swept fro[...]Article
Bien que l' absorbance large bande (WBA) fournit des informations importantes sur le fonctionnement de l' oreille moyenne, il y a peu de recherches sur l'utilisation de WBA pour évaluer la dysfonction tubaire (ETD). À ce jour, WBA obtenu sous la[...]Article
Chris A. Sanford, Auteur ; Jeff E. Brockett, Auteur ; Venkatesh Aithal, Auteur ; Hammam A. AlMakadma, Auteur |A number of studies have produced normative and developmental data and examples of wideband acoustic immittance (WAI) obtained in ears with pathologies and or dysfunction. However, incorporation of this tool into clinical audiology and otolaryng[...]Article
Background: Diagnosing conductive conditions in newborns is challenging for both audiologists and otolaryngologists. Although high-frequency tympanometry (HFT), acoustic stapedial reflex tests, and wideband absorbance measures are useful diag[...]Article
Background Wideband absorbance (WBA) measured at ambient pressure (WBAA) does not directly account for middle ear pressure effects. On the other hand, WBA measured at tympanometric peak pressure (TPP) (WBATPP) may compensate for the middle ear [...]Article
To study the developmental characteristics of sweep frequency impedance (SFI) measures in healthy infants from birth to 6 months. Design: All infants were assessed using high-frequency tympanometry (HFT), distortion product otoacoustic emission [...]Article
Hammam A. AlMakadma, Auteur ; Sreedevi Aithal, Auteur ; Venkatesh Aithal, Auteur ; Joseph Kei, Auteur |With widespread agreement on the importance of early identification of hearing loss, universal newborn hearing screening (UNHS) has become the standard of care in several countries. Despite advancements in screening technology, UNHS and early he[...]Article
Objectives The objective of this study was to describe wideband absorbance (WBA) findings in patients with cholesteatomas and retraction pockets (RPs). Design In this prospective study, tympanometry, audiometry, and wideband tympanometry (W[...]Article
Objectives : The objective of the present study was to describe pressurized wideband absorbance at tympanometric peak pressure (WBATPP) and 0 daPa (WBA0) in healthy Caucasian neonates. Subjects : A total of 249 ears from 249 neonates who passed [...]
