Background: Hearing loss due to chronic otitis media is common. The purpose of this study was to evaluate hearing before and after canal wall up, canal wall down mastoidectomy and tympanoplasty. Methods: From 2004 to 2007, all patients with chronic otitis media who were admitted at the Department of Otolaryngology, Babol Medical University were studied. For 126 patients' canal wall up, canal wa...

The aetiology of hearing loss in humans is multifactorial. Besides genetic, environmental and infectious causes, several endocrine and metabolic abnormalities are associated with varying degrees of hearing impairment. The pattern of hearing loss may be conductive, sensori-neural or mixed. The neurophysiology of hearing as well as the anatomical structure of the auditory system may be influenced...

Objective: To determine the relationship of sensori neural hearing loss and surgery for chronic otitis media. Methodology: This study was designed as a clinical trial on 90 patients with chronic otitis media (COM), who were admitted in hospital for Tympanoplasty and Mastoidectomy who were selected for the study. A pre and post, bone conduction hearing test was performed in frequencies 250 to 40...

Inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (CRF), regular dialysis treatment (RDT) and sensorineural hearing loss (SNHL) is still a debatable field. The object of this paper was to verify the presence of SNHL in patients submitted to hemodialysis with different duration due to CRF and in those submitted to conservat...

Tinnitus and hyperacusis are common and potentially serious hearing disorders associated with noise-, age- or drug-induced hearing loss. Accumulating evidence suggests that tinnitus and hyperacusis are linked to excessive neural activity in a distributed brain network that not only includes the central auditory pathway, but also brain regions involved in arousal, emotion, stress and motor contr...

Background: Hearing disorders are reported in thalassemia patients treated with deferoxamine. This study aimed to assess hearing loss in Iranian thalassemia major patients treated with deferoxamine. Methods: This review article was designed based on PRISMA guidelines. To review the literature, two researchers studied national and international databases including Iranmedex, Magiran, Medlib, SI...

introduction: hearing loss from birth up to the age of 3 years has a negative effect on speech/language development and results in sensory, cognitive, emotional, and academic defects in adulthood by causing delayed development of communicative-linguistic abilities. the present study was performed in order to assess the effect of early intervention on language development in persian children age...
