BACKGROUND Pathologies that alter the impedance of the middle ear may consequently modify the DPOAE amplitude. The aim of this study was to correlate information from 2 different clinical procedures assessing middle ear status. Data from DPOAE responses (both DP-Gram and DP I/O functions) were correlated with data from multi-component tympanometry at 1000 Hz. MATERIAL AND METHODS The subjects w...

Early hearing screening and diagnosis in newborns are important in order to avoid problems with language acquisition and psychosocial development. Current newborn hearing screening tests cannot effectively distinguish conductive hearing loss from sensorineural hearing loss, which requires different medical approaches. Tympanometry is a fast and accurate hearing test routinely used for the exami...

OBJECTIVE Scandinavian guidelines recommend controlling middle-ear effusion (MEE) after acute otitis media. The study aim was to determine whether nurses without otoscopic experience can reliably exclude MEE with tympanometry or spectral gradient acoustic reflectometry (SG-AR) at asymptomatic visits. DESIGN Three nurses were taught to perform examinations with tympanometry and SG-AR. Pneumati...

OBJECTIVE To evaluate the usefulness of pure-tone audiometry, tympanometry, and liquid and acoustic reflex (AR) tests in the differential diagnosis of ossicular fixation and discontinuity. DESIGN A prospective clinical trial. SETTING Tertiary referral center. PATIENTS Thirty-nine patients (46 ears) undergoing operations at University of Tsukuba Hospital, Tsukuba, Japan, from 1990 through ...

Materials and Methods: This retrospective study was performed on 26 patients with acromegaly and 27 age-matched healthy controls. Otoscopic examination, pure tone odiometry, tympanometry, otoacoustic emissions, and stapes reflex were performed in all cases. Hearing thresholds of air and bone conduction (AC and BC), middle ear function, cochlear function, tympanic membrane compliance, gradient, ...
