A 34-year-old woman who was revealed to have Usher’s syndrome is reported. She was diagnosed with sensorineural hearing loss necessitating the use of hearing aids at the age of 6 and started to have progressive night vision loss when she was a teenager. Few years later, she developed daytime peripheral vision loss. She had normal intrauterine life with an uncomplicated birth. She denied any diz...

the aim of this study was to compare the static and dynamic balance performance of deaf children with and without cochlear implants. this is a cross-sectional study of 145 school children, aged between 7 and 12 years comprising 85 children with congenital or early acquired bilateral profound sensorineural hearing loss (the hearing loss group) and 60 normal hearing aged-matched control counterpa...

Non syndromic hearing impairment is a common sensory disorder, which affects one in 600 newborns. Though more than 50 nuclear genes are involved in causing non syndromic hearing impairment, mutations in the connexin 26 (GJB2) gene explain a high proportion of congenital deafness in several populations worldwide. The diversity of genes and genetic loci implicated in hearing loss defines the comp...

Background and aims: Hearing loss (HL) happens due to the genetic or environmental causes or both. Risk factors include congenital infections and congenital deformities of auricle and ear duct. The present study was performed to briefly explain the genetics, molecular biology and epidemiology of HL in Middle East especially in Iran. Methods: An intense an...

INTRODUCTION Congenital cholesteatoma is thought to be caused by inadequate folding of the epidermoid formation inside the middle ear cleft. During development of the middle ear mucosa, stratified squamous epithelium accumulates in the embryonic life. Its typical appearance is a "pearl" beneath the anterosuperior quadrant of the tympanic membrane. PRESENTATION OF CASE We report 28 years-old c...
