For many otologists and audiologists, otosclerosis is not a puzzling condition anymore.
Advances in diagnostic and therapeutic procedures have provided a vast number of patients …

The aim of the present paper was to review the current knowledge on multi-frequency
tympanometry and explore its role as a diagnostic tool in various otologic conditions …

Objective: The major goal of this study was to examine differences in the middle ear
mechano-acoustical properties of normal ears and ears with surgically confirmed …

Objectives: Wideband reflectance (WBR) is a middle ear analysis technique that quantifies
frequency-specific sound conduction over a wide range of frequencies. One shortcoming of …

Objective: This study compares measurements of ear-canal reflectance (ECR) to other
objective measurements of middle ear function including audiometry, umbo velocity (VU) …

Laser Doppler vibrometry was used to measure the sound-induced tympanic membrane
(TM) velocity, assessed near the umbo, in 56 normal hearing human subjects at nine sound …

Objective: This study examined differences between the middle ears of two ethnic groups,
Caucasian and Chinese young adults with normal hearing, using a new middle-ear …

Objective: This study examined differences between a group of normal-hearing Caucasian
and Chinese young adults on six tympanometric parameters. The goal of this study was to …

Background Conductive hearing loss is occasionally recognized in large vestibular
aqueduct (LVA) syndrome; however, the incidence rate and the cause are not known …

Two “must read” articles on the development of clinical tympanometry are Terkildsen and
Thomsen (1959) and Terkildsen and Scott-Nielsen (1960). Their interest in estimating …
