Wideband middle ear power (WMEP) measurement is a method of middle ear analysis that may provide improved diagnostic capability over single-frequency tympanometry. However, normative data, information about test-retest reliability, and results in clinical disorders are needed for clinical application. Normative and reliability data on WMEP in children three days to 47 months of age were obtaine...

Background and objectives: Type I tympanoplasty is a common otologic surgery which aims to repair the eardrum integrity. Different views have been reported concerning this procedure in young ages and the best moment to perform surgery remains controversial. Surgery in early adolescence appears to achieve the same outcomes than adulthood and without disadvantages of childhood. Characteristics of...

In order to evaluation effect of different level of humic acid affected drought stress on seed yield, its components and morphological traits of corn a research farm was conducted according split plot experiment based randomized complete blocks design at three replication during 2015 year. Main factor included four irrigation regimes (90mm, 110 mm, 130 mm and 150mm evaporation from pan class A)...

Background: Diabetic neuropathy is one of the major complications reported widely in type 2 diabetes. It affects all the sensory, autonomic and motor systems including auditory pathway. Objectives: Present study is focused on functional analysis of auditory pathway by Brainstem Auditory Evoked Response (BAER) and with Pure Tone Audiometry (PTA) in type 2 diabetes. To compare the same in healthy...

the exposure to electromagnetic field emitted by mobile telephones is increasing rapidly worldwide that causes side effects, including thermal and non thermal side effects. ear proximity to electromagnetic source may lead to greater damage and side effects, including hearing loss. this study was performed to assess the chronic effect of exposure to electromagnetic field of mobile telephones on ...

introduction: to reduce incidence of residual cholesteatoma following ear surgery; and to reduce the need for second look “open” mastoidectomy using endoscopic mastoidotomy. ten-year retrospective chart review of 249 primary cholesteatoma cases (1994-2004) with a minimum follow-up of two years.  the first objective was to evaluate the effectiveness of otoendoscopy in reducing the incidence of “...

Ceruminous adenoma, also called ceruminoma, ceruminal adenoma, apocrine adenoma, or even cylindroma in the past (the latter three terms are discouraged) is a benign glandular neoplasm of ceruminous glands (modified apocrine sweat glands) that arises solely from the external auditory canal. By definition, this tumor type cannot involve the auricular cartilages, ear lobe, or other such external e...

Meningiomas are slowly progressive, benign tumors that originate from meningothelial cells. Extracranial meningiomas, especially isolated middle ear meningiomas, are very rare. In this article, we report a rare secretory type primary middle ear meningioma which was histopathologically confirmed in a 46-year-old female patient who presented with otological and neurootological symptoms.

To advance the understanding of genetic mechanisms involved in the patterning and the differentiation of the vertebrate auditory system, we screened for mutations affecting ear development in the zebrafish larva. Fifteen recessive mutant alleles have been isolated and analyzed. The phenotypes of these mutants involve abnormalities in ear morphology, otolith formation, or both processes in paral...
