Background and purpose: Hearing impaired children with cochlear implant experience many problems as they have developmental language impairments with impaired working memory. The aim of this study was to develop a working memory test and investigating the working memory in children with cochlear implant. Materials and methods: In this cross sectional study, a Persian working memory scale for c...
Introduction: Literature regarding the different degrees of hearing loss in patients with Cornelia de Lange syndrome (CDLS) reports that half of the affected patients exhibit severe to profound sensorineural hearing loss. We present the first pre-school child with CDLS who underwent cochlear implantation for congenital profound sensorineural hearing loss. Case Report: A 3-year-old boy with CD...
HYPOTHESIS This study investigated whether pressure changes common to scuba diving and to hyperbaric oxygen therapy would not cause crush damage or leakage from critical seals in commercially available cochlear implants. BACKGROUND The implanted packages of cochlear implants are susceptible to electrical failure caused by leakage from critical seals and to crush injury when exposed to changin...
Aim: Regarding the importance of language in communication and the key role of hearing in it, speech quality assessment in determining the ability of an individual is an suitable index. The purpose of this study was to analyze the speech quality of MLU, lexical richness, the number of content words and function words in 6-4 years low birth bringing Deaf cochlear implant in comparison with peers...
Objectives: The aim of present study was evaluation of saccule function in cochlear implant candidates with severe to profound sensory neural hearing loss Before and after cochlear implantation Methods: In this study 35 cochlear implant (CI) candidates with bilateral severe to profound sensory neural hearing loss before and about 30 days after cochlear implant and 20 normal-hearing cases as ...
objective: the present study aimed to investigate the effects of group positive psychotherapy on increasing the happiness of mothers of children with cochlear implants. methods: this study was a quasi-experimental research with pretest-posttest, a control group, and a 75-day follow-up design. a total of 20 mothers of children with cochlear implants treated in baqiyatallah hospital of tehran ci...
OBJECTIVES/HYPOTHESIS Oxidative stress plays a substantial role in the genesis of noise-induced cochlear injury that causes permanent hearing loss. We present the results of three different approaches to enhance intrinsic cochlear defense mechanisms against oxidative stress. This article explores, through the following set of hypotheses, some of the postulated causes of noise-induced cochlear o...
The inner hair cell stereocilia of the guinea pig cochlea was examined under a scanning electron microscope (SEM) after loud tone exposure onto the ear drum of the animal. Before and after guinea pigs were exposed to intensive and continuous tone such as 106 dB SPL in intensity, the functioning of the cochlea was monitored by N1-N2 audiograms. The structural damage of the stereocilia of inner h...
