BACKGROUND AND PURPOSE Our purpose was to evaluate the differential findings of tuberculous otomastoiditis (TOM) and nontuberculous chronic otomastoiditis with or without middle ear cholesteatoma on high-resolution CT of the temporal bone. MATERIALS AND METHODS We reviewed 19 cases of TOM, 30 cases of chronic otomastoiditis (COM), and 30 cases of COM with cholesteatoma (CHOM), all of which ha...
The lack of baleen whale (Cetacea Mysticeti) audiograms impedes the assessment of the impacts of anthropogenic noise on these animals. Estimates of audiograms, which are difficult to obtain behaviorally or electrophysiologically for baleen whales, can be made by simulating the audiogram as a series of components representing the outer, middle, and inner ear (Rosowski, 1991; Ruggero and Temchin,...
The middle ear apparatus is composed of three endochondrial ossicles (the stapes, incus and malleus) and two membranous bones, the tympanic ring and the gonium, which act as structural components to anchor the ossicles to the skull. Except for the stapes, these skeletal elements are unique to mammals and are derived from the first and second branchial arches. We show that, in combination with g...
background and aim: auditory processing disorders may have detrimental consequences on a child’s life, if undiagnosed and untreated. the multiple auditory processing assessment (mapa), as a valid model, has been introduced for central auditory processing assessment and diagnosis in school children. the purpose of this study was to design and evaluate the persian version of mapa for auditory pro...
The New Zealand bigeye, Pempheris adspersa, is a nocturnal planktivore and has recently been found to be an active sound producer. The rostral end of the swim bladder lies adjacent to Baudelot's ligament which spans between the bulla and the cleithrum bone of the pectoral girdle. The aim of this study was to use the auditory evoked potential technique to physiologically test the possibility tha...
INTRODUCTION Animal studies are an essential method to evaluate implants for the middle ear prior to clinical studies. New Zealand rabbits, guinea pigs and chinchillas are, among other small mammals, well established animal models, but their auditory system is significantly smaller compared to human. Hence, the suitability of the domestic pig (sus scrofa domesticus) as a new animal model for re...
The incidence and clinical features of temporal bone fractures have been well documented in the medical literature. Characteristically, longitudinal fractures account for 80% of the total [1, 2] and result from trauma to the parietal and temporal regions of the skull [3]. The fracture line starts at the tympanic annulus and runs parallel to the petrous pyramid, traversing the external auditory ...
