introduction: otosclerosis one of the most common causes of conductive hearing loss is more common in females and in their middle ages. it is usually a bilateral and progressive disease. surgical operation is suggested as the exclusive management of otosclerosis. this study aims to evaluate the hearing results after stapedectomy in otosclerotic patients in ahwaz. materials and methods:  in this...

objectives: tooth loss appears to have an important role in the loss of mastication and esthetics. the aim of this systematic review was to investigate the prevalence of tooth loss and edentulism in the iranian population. methods: studies reviewed in this article were primarily identified via search of the online bibliographic databases including pubmed and iranian biomedical journals, by usin...

conclusions it is likely that learning social skills in adolescents with deafness would improve their sense of competence, and emotional well being. results the intervention led to significant improvement in total perceived competence scores of adolescents with deafness (p < 0.001) as well as in three domains of socio-emotional competence (p = 0.003), communication competence (p < 0.001), and s...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

Introduction: Children learn to communicate by hearing sounds. If there is hearing loss, the cognitive and speaking abilities and language learning will deteriorate. Early detection and intervention are important factors in the successful treatment of hearing loss in children. Hearing loss (HL) is divided into two main groups: conductive hearing loss (CHL) and sensorineural hearing loss (SNHL)...

introduction: serum anti endothelial cell antibodies (aecas) play a prominent role in idiopathic sensorineural hearing loss (snhl) in that they induce vascular damage (immune mediated).the of the current study is  to compare aecas in serum and perilymphatic .uid of idiopathic snhl children (<15y) undergoing cochlear implant surgery.methods: this was a cross sectional study performed in the coch...

analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. according to this, an impressive analytical method which is called modified iteration perturbation method (mipm) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. this new method is combined by the mickens and iteration methods. moreover, this method don...

hearing loss and meningitis were correlate in some aspects. hearing loss is the situation that can be shown in cochlear or retrocochlear defects. cochlear hearing loss is caused by inner or outer hair cell damage (however cochlear hearing loss has another causes, such as defect of arterial spiral ganglion, basilar and tectorial membrane) and retrocochlear hearing loss has neural origin and meni...
