[ 1 ] - Effects of Fish Oil Supplementation during the Suckling Period on Auditory Neural Conduction in n-3 Fatty Acid-Deficient Rat Pups

Abstract Introduction: Omega 3 fatty acid especially in the form of fish oil, has structural and biological role in the body's various systems especially nervous system. Numerous studies have tried to research about it. Auditory is one of the affected systems. Omega 3 deficiency can have devastating effects on the nervous system and auditory. This study aimed to evaluate neural conduction in n-...

[ 2 ] - Translation, Validity, and Reliability of a Persian Version of the Iowa Tinnitus Handicap Questionnaire

Introduction: Tinnitus is a common otologic symptom that can seriously affect a patient’s quality of life. The purpose of the present study was to translate and validate the Iowa Tinnitus Handicap Questionnaire (THQ) into the Persian language, and to make it applicable as a tool for determining the effects of tinnitus on a patient’s life.   Materials and Methods: The main version of the THQ was...

[ 3 ] - 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 (...

[ 4 ] - Temporal Processing Evaluation in Tinnitus Patients: Results on Analysis of Gap in Noise and Duration Pattern Test

Introduction: Tinnitus is a perception of sound without external source. For complete assessment of tinnitus, central auditory processing abilities should be considered in addition to the routine psychological evaluation of tinnitus characteristics. Temporal processing is one of the important auditory skills that are necessary for complex higher level auditory processing.   Materials and Method...

[ 5 ] - Vestibular Evoked Myogenic Potential Produced by Bone-Conducted Stimuli: A Study on its Basics and Clinical Applications in Patients With Conductive and Sensorineural Hearing Loss and a Group With Vestibular Schawannoma

Introduction: Vestibular evoked myogenic potential (VEMP) has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC) stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients.   ...

[ 6 ] - Audiological Manifestations in Vitiligo Patients

Introduction: The hallmark of vitiligo is the disappearance of melanocytes from the skin due to an as yet unidentified mechanism. The presence of melanocytes in the auditory apparatus suggests that this system could possibly be affected by vitiligo, which targets the melanocytes of the whole body and not just the skin.The purpose of this study was to assess the incidence of auditory alteration...
