Distortion product otoacoustic emissions in tinnitus patients.
Tinnitus is a symptom that affects a great number of patients. Its diagnosis, treatment, and follow-up are difficult, owing to its subjectivity. The authors propose the use of distortion product otoacoustic emissions (DPOAEs) in tinnitus evaluation. They studied three groups: controls, having no complaint of tinnitus and normal hearing; group 1, presenting tinnitus and normal audiometry; and gr...
متن کاملEvaluation 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 کاملSpecific findings in distortion product otoacoustic emissions and growth functions with chronic tinnitus.
Chronic tinnitus has a very high prevalence in industrialized countries. Latest studies found chronic tinnitus in 4% of the German population, with almost 2% suffering severely in their daily life. Because no curative therapeutic approach is available--neither pharmacological nor surgical--the main focus lies in treatments that enhance the habituation of tinnitus. Habituation occurs in almost 5...
متن کاملVariation of distortion product otoacoustic emissions with furosemide injection.
Cochlear function was monitored in adult gerbils using distortion product otoacoustic emissions (DPOAE) during intraperitoneal injection of furosemide. All stimulus parameters were varied independently over a wide range, the stimulus frequencies f1 and f2 from 1 to 16 kHz, and the stimulus levels L1 and L2 from 20 to 80 dB SPL. The observed emissions at 2f1-f2 and 3f1-2f2 could be considered to...
