OBJECTIVES/HYPOTHESIS To measure the volume of the endolymph drainage system in temporal bone specimens with Ménière disease, as compared with specimens with endolymphatic hydrops without vestibular symptoms and with nondiseased specimens STUDY DESIGN: Comparative human temporal bone analysis. METHODS We generated three-dimensional models of the(More)
OBJECTIVE To evaluate the histopathologic changes of dark, transitional, and hair cells of the vestibular system in human temporal bones from patients with chronic otitis media. STUDY DESIGN Comparative human temporal bone study. SETTING Otopathology laboratory. SUBJECTS AND METHODS To compare the density of vestibular dark, transitional, and hair(More)
OBJECTIVES/HYPOTHESIS To determine if peripheral vestibular otopathology is present in human temporal bones with otosclerosis. STUDY DESIGN Comparative human temporal bone study. METHODS Seventy-four human temporal bones from 46 subjects with otosclerosis (mean age of 61 ± 18 years) and 20 within histologically normal limits from 17 subjects (mean age(More)
OBJECTIVE Endoscopic procedures are becoming common in middle ear surgery. Inflammation due to chronic ear disease can cause bony erosion of the carotid artery and Fallopian canals, making them more vulnerable during surgery. The objective of this study was to determine whether or not chronic ear disease increases dehiscence of the carotid artery and(More)
OBJECTIVES/HYPOTHESIS To compare the volume of the epitympanic space, as well as the area of the tympanic isthmus, in human temporal bones with retraction pockets to those with chronic otitis media without retraction pockets and to those with neither condition. STUDY DESIGN Comparative human temporal bone study. METHODS We generated a three-dimensional(More)
Background Bacterial resistance in acute otitis can result in bacterial persistence and biofilm formation, triggering chronic and recurrent infections. Objective To investigate the middle ear inflammatory response to bacterial infection in human and chinchilla temporal bones. Design, Setting, and Participants Six chinchillas underwent intrabullar(More)
