Multifrequency tympanometry: effects of ear canal volume compensation on middle ear resonance.
Sweep frequency tympanograms compensating for ear canal volume at 200 and -400 daPa were obtained on 106 ears of 53 subjects during four different sessions. Resonance frequencies were obtained and analyzed to determine normative data, resonance differences between the compensation methods, and the interaction effect of running consecutive tympanograms. There were no gender or interaural differe...
متن کاملThe Effect of Ethnicity on Wideband Absorbance of Neonates with Healthy Middle Ear Functions in Malaysia: A Preliminary Study
BACKGROUND AND OBJECTIVES Although ethnicity effect on wideband absorbance (WBA) findings was evident for adults, its effect on neonates has not been established yet. This study aimed to investigate the influence of ethnicity on WBA measured at 0 daPa from neonates with healthy middle ear functions. SUBJECTS AND METHODS Participants were 99 normal, healthy, full-term newborn babies with chron...
متن کاملWideband middle ear power measurement in infants and children.
Wideband middle ear power (WMEP) measurement is a method of middle ear analysis that may provide improved diagnostic capability over single-frequency tympanometry. However, normative data, information about test-retest reliability, and results in clinical disorders are needed for clinical application. Normative and reliability data on WMEP in children three days to 47 months of age were obtaine...
متن کاملTympanometry and CT Measurement of Middle Ear Volumes in Patients with Unilateral Chronic Otitis Media
OBJECTIVES The goals of the study were to compare the middle ear (ME) volumes from both normal and lesioned ears, and these ME volumes were measured by a digital image processing computed tomography (CT) program in patients with unilateral chronic otitis media, and we wanted to compare the ME volumes of the lesioned ears by comparing the ME volumes obtained by tympanometry with those ME volumes...
متن کاملMeasuring middle ear admittance in newborns using 1000 Hz tympanometry: a comparison of methodologies.
The present study aimed to compare three measures to estimate middle ear admittance in neonates using 1000 Hz tympanometry. Data were obtained from 36 full-term newborns, aged between 24 and 123 hours, who passed a transient evoked otoacoustic emissions test and assessed using a Madsen Otoflex impedance meter. The results showed that the mean middle ear admittances obtained by compensating for ...
