OBJECTIVES In this study, we aimed to evaluate the anatomical and functional results of open cavity tympanomastoidectomy due to chronic otitis media with cholesteatoma. PATIENTS AND METHODS Between January 2003 and October 2009, 166 patients who underwent open cavity tympanomastoidectomy due to chronic otitis media with cholesteatoma in our clinic were retrospectively analyzed. Seventy-two ea...

Allergen-induced inhibition of pulmonary surfactant in asthma may promote airway oedema and consequently potentiate the severity of the asthmatic response. A randomised, single-blind, cross-over study of an inhaled synthetic phospholipid dry-powder surfactant (Pumactant) was conducted in atopic, asthmatic subjects with previously documented early and late asthmatic responses (EAR and LAR) to an...

Abstract Introduction A cholesteatoma is a three-dimensional sac lined by keratinized squamous epithelium containing desquamated epithelial cell which secretes enzymes that have the tendency to expand and erode bony structure underlying it cause intracranial extracranial complications. This cystic mass in an abnormal location such as middle ear, petrous apex, or external auditory canal (EAC). I...

OBJECTIVE Removing the posterior canal wall or canal wall down mastoidectomy (CWDM) for the management of cholesteatoma remains controversial. We advocate partial removal of the posterior canal wall for complete eradication, followed by canal wall defect reconstruction to restore the normal anatomy and avoid the complications of CWDM. MATERIALS AND METHODS Sixty-four patients with cholesteato...

The purpose of the research is to conduct a comprehensive assessment new spring barley variety ‘in Memory Dudin’ on economically valuable signs. Studies were carried out in 2016-2019. “in was created by method directional individual selection from variant with treatment ‘Bios 1’ laser red light (wavelength 632.8 nm, continuous irradiation mode, beam power density 0.3 mW/cm 2 ) for 60 minutes, f...

Introduction The objectives of mastoidectomy in cholesteatoma are a disease-free and dry ear, the prevention of recurrent disease, and the maintenance of hearing or the possibility to reconstruct an affected hearing mechanism. Canal wall down mastoidectomy has been traditionally used to achieve those goals with greater or lesser degrees of success. However, canal wall down is an aggressive appr...

Several studies have demonstrated that delays associated with evoked otoacoustic emissions (OAEs) largely originate from filter delays of resonant elements in the inner ear. However, one vertebrate group is an exception: Anuran (frogs and toads) amphibian OAEs exhibit relatively long delays (several milliseconds), yet relatively broad tuning. These delays, also apparent in auditory nerve fiber ...

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 ...
