Expression of Prostaglandin E2 Receptors in Acquired Middle Ear Cholesteatoma
OBJECTIVES To investigate the expression of prostaglandin E2 receptor subtypes, E-prostanoid (EP) 1-4 receptors, in acquired cholesteatoma and its possible role in the pathologic process of this disorder. METHODS Specimens of human acquired cholesteatoma were obtained from 29 patients and 19 skin biopsies of normal external auditory canal were as controls. The mRNA and protein expression of E...
متن کاملExpression of RANKL and proliferation abilities of cultured human middle ear cholesteatoma epithelial cells.
One of the most distinct characteristics of middle ear cholesteatomas is their capacity for bone destruction during the growth process. In this study, we examined the relationship between inflammatory mechanisms and both bone absorption and the proliferation of epithelial cholesteatoma cells. Cultured cholesteatoma epithelial cells were stimulated by lipopolysaccharide (LPS) and dexamethasone (...

متن کاملEndoscopic Middle Ear and Mastoid Surgery for Cholesteatoma
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 “...
متن کاملAnimal Models of Middle Ear Cholesteatoma
Middle ear acquired cholesteatoma is a pathological condition associated with otitis media, which may be associated with temporal bone resorption, otorrhea and hearing loss, and occasionally various other complications. Cholesteatoma is characterized by the enhanced proliferation of epithelial cells with aberrant morphologic characteristics. Unfortunately, our understanding of the mechanism und...
