Allergy and recurrent middle ear effusion
Objectives: The aim of this study was to compare the otitis media with effusion (OME) groups that improved when treated with adenoidectomy and Ventilation Tube (VT), to the group of the recurred after surgery and detect the possible role of allergy in OME. Material and Methods: This study was performed on two groups. The Patient group consisted of 38 patients with recurrent OME with allergy an...
متن کاملCLASSIFICATION OF CONGENITAL MIDDLE AND EXTERNAL EAR MALFORMATIONS: CT STUDY
The authors used high-resolution computed tomography (HRCT) for studying 52 congenitally malformed ears in 45 children between five and 10 years of age. In six children the malformations were bilateral. The malformations clinically manifested as microtia, atresia of the external auditory canal and conductive deafness. Analyzing anatomical details and pathological changes on HRCT axial sec...
متن کاملMorphology and morphometrical study of hamster middle ear bones
The objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. Twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. After dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. Finally, all data were evaluated and analysed using the Sigma Statt software. T...
متن کاملAcoustic Immittance, Absorbance, and Reflectance in the Human Ear Canal.
Ear canal measurements of acoustic immittance (a term that groups impedance and its inverse, admittance) and the related quantities of acoustic reflectance and power absorbance have been used to assess auditory function and aid in the differential diagnosis of conductive hearing loss for over 50 years. The change in such quantities after stimulation of the acoustic reflex also has been used in ...
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 “...
