Evaluation of clear speech perception in patients with Auditory Neuropathy

2015 | Keywords AN CLEAR SPEECH,

INTRODUCTION: One of the main characteristic of auditory neuropathy (AN) is a significantly impaired temporal processing ability with subsequent difficulty in speech understanding particularly in noise. Temporal modification of speech by enhancing temporal properties in clear speech can be beneficial in enhancing speech intelligibility in AN patients. Clear speech was developed in English language and many studies showed it is ... Read more

Impact of Cochlear Implantation on Vestibular Function

2015 | Keywords CI Vestibular VNG CDP VEMP,

OBJECTIVE: To determine the impact of cochlear implantation (CI) on the vestibular function. METHODOLOGY: Prospective cohort study done on twenty seven adult patients before and after CI. Vestibular function was assessed using clinical vestibular examination, caloric video-nystagmography (VNG), vestibular-evoked myogenic potentials (VEMP), sensory organization test of computerized dynamic posturography (S0T-CDP) and Dizziness Handicap Inventory (DHI). RESULTS: 27 adult CI candidates ... Read more

: Effect of strabismus on vestibular functions: value of its correction

2014 | Keywords strabismus vestibular,

OBJECTIVE Studies that evaluate the relationship between strabismus and vestibular functions are very scarce with no consensus between their results. Hence, this study was designed to evaluate vestibular functions in patients with strabismus and to find out the effect of surgical correction of strabismus on vestibular functions. MATERIALS AND METHODS Thirty patients with strabismus aged between 10 and 33 years ... Read more

Abstract: Aim of the study: This study was carried out to assess the effects of high blood pressure and its associated changes in the form of high fibrinogen level and high plasma atrial natriuretic peptide (ANP) level on hearing threshold in hypertensive patients. In this study, 100 persons (200 ears) 50 males and 50 females, with age range of 50-55 ... Read more

Evaluation of Serum Zinc Level and Plasma Super Oxide Dismutase Activity in Tinnitus Patients: Value of Zinc Supplementation

2010 | Keywords Tinnitus, Reactive oxygen spec,

OBJECTIVE: Zinc is a structural component of super oxide dismutase (Cu/Zn SOD) that has a vital antioxidant role. It is among the first line of defense in detoxification of products resulting from oxidative stress. It has been recently observed that Reactive oxygen species (ROS) are implicated in the pathology of the inner ear and the peripheral and central auditory pathways. ... Read more

Role of Zinc and Low Level Laser Therapy in Management of Tinnitus

2010 | Keywords Zinc LOW LEVEL LASER,

Tinnitus is an auditory percept in the absence of an external sound source (FIGUEIREDO ET AL., 2010). It is a worldwide problem that remains poorly understood by healthcare professionals (LIM ET AL., 2010). Tinnitus is highly prevalent disease, 15% in the general population and 33% in the elderly (Holdefer et al., 2010). But only 2% consider it to be an ... Read more

Value of Head Shake Sensory Organization Test (HS-SOT) in Detecting Subclinical Vestibular Disorders in Type 2 Diabetic Patients

2010 | Keywords DM HS SOT, DM HS-SOT CDP, Head Shake Sensory organisatio, SOT, DM, CDP, HS-SOT,

Objective: Glucose metabolism has a significant impact on inner ear physiology, and both hypoglycemia and hyperglycemia may affect its normal function. Patients with glucose metabolism alteration, as it happens in diabetes, may present with auditory or vestibular symptoms, or both. Recent clinical studies have demonstrated that the Head Shake Sensory Organization Test (HS-SOT) of Computerized Dynamic Posturography (CDP) can be ... Read more
