Evaluation of Distortion and Transient Evoked Otoacoustic Emission in Tinnitus Patients with Normal Hearing
Introduction: Tinnitus is a perception of sound without external source. The exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. The aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of Distortion-Product Evoked Otoacoustic Emission (...
متن کاملhearing status in neonatal hyperbilirubinemia by auditory brain stem evoked response and transient evoked otoacoustic emission
hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. if left untreated, it may cause certain cerebral damage. this study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. this study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dl). auditory brainstem response (abr) and transient evoked o...
متن کاملInvestigating outer hair cell motility with a combination of external alternating electrical field stimulation and high-speed image analysis.
OHCs are cylindrical sensorimotor cells located in the Organ of Corti, the auditory organ inside the mammalian inner ear. The name "hair cells" derives from their characteristic apical bundle of stereocilia, a critical element for detection and transduction of sound energy. OHCs are able to change shape -elongate, shorten and bend- in response to electrical, mechanical and chemical stimulation,...
متن کاملTransient Evoked Otoacoustic Emission in Neonates with and without Vernix
Transient evoked otoacoustic emissions (TEOAEs) are not necessarily recordable in all healthy neonates, before discharge, due to transient conditions (such as vernix in ear canals). To determine the possibility and feasibility of screening of very young newborns before discharge from hospital (JCIH, 2007), it is important to know how vernix in external ear during this time affects screening res...
متن کاملTechnical report: distortion product otoacoustic emissions that are not outer hair cell emissions.
PURPOSE To present a case study in order to alert clinicians to the possibility of occurrence of intermodulation distortion during otoacoustic emissions testing that arises from the cavity formed by the external auditory meatus and tympanic membrane rather than from the inner ear, compromising the reliability and validity of otoacoustic emissions testing. RESEARCH DESIGN Prospective case stud...
