Tympanometry in neonates with normal otoacoustic emissions: measurements and interpretation.
UNLABELLED Tympanometry is used in evaluating middle ear functional conditions. Before six months of age its results may be misleading. High frequency studies aim to provide more valid procedures. AIM To describe and discuss tympanometric measurements and the interpretation in normal hearing neonates at 226, 678 and 1000Hz. METHOD 110 neonates that were analyzed had normal otoacoustic emiss...
متن کاملHigh Frequency Tympanometry (1,000 Hz) for Neonates with Normal and Abnormal Transient Evoked Otoacoustic Emissions
BACKGROUND AND OBJECTIVES This paper aimed at evaluating the characteristics of high-frequency (1,000 Hz) acoustic admittance (ya) for the neonates with transient evoked otoacoustic emissions (TEOAE) as either pass or refer group. SUBJECTS AND METHODS Using a 1,000 Hz probe tone, 297neonates (152 male, 145 female aged 0-104 days old) were evaluated. Tympanometric parameters admittance value a...
متن کاملMultifrequency tympanometry and evoked otoacoustic emissions in neonates during the first 24 hours of life.
Multifrequency, complex-component tympanograms and transient evoked otoacoustic emissions (EOAEs) were recorded in 55 neonates less than 24 hours of age. The purpose of the investigation was to determine the normal middle ear immittance characteristics of neonates less than 24 hours old (the approximate discharge age of well-babies) and to assess whether an association exists between transient ...
متن کاملTransient Evoked Otoacoustic Emissions and High Risk Register in Neonates
The development and application of otoacoustic emissions in clinical practice marked the beginning of a new era in the field of screening for congenital hearing loss. In particular, transient evoked otoacoustic emissions (TEOAEs) have been widely adopted by many universal hearing screening (UNHS) programs. The test is quick, non-invasive, objective, sensitive, frequency specific, relatively che...
متن کاملOtoacoustic emissions in normal-cycling females.
The purpose of this study was to determine if the menstrual cycle influences the amplitude of transient (TEOAEs) and distortion-product (DPOAEs) otoacoustic emissions. Thirteen normal-hearing, normal-cycling females were monitored weekly for 12 weeks. TEOAE and DPOAE amplitudes were analyzed to determine if amplitude changes could be detected and correlated to phases of the menstrual cycle. No ...
