Abstract:

The reversible hearing loss in the nonoperated ear noted by patients after ear surgery remains unexplained. This study proposes that this hearing loss is caused by drill noise conducted to the nonoperated ear by vibrations of the intact skull. This noise exposure results in dysfunction of the outer hair cells, which may produce a temporary hearing loss. Estimations of outer hair cell function in the nonoperated ear were made by recording the change in amplitude of the distortion-product otoacoustic emissions before and during ear surgery. Reversible drill-related outer hair cell dysfunction wa

Hand-held scanners delivered accurate images for post-processing of the mesh and for printing in a cost- and time efficient way.

Abstract:

Abstract Hearing screening programs using otoacoustic emissions can have high false positive rates, due to temporary middle-ear and outer-ear disorders. This is especially the case for newborns, infants, and young children. Standard tympanometry is limited, uncomfortable, and unreliable in young ears. By incorporating wideband acoustic power flow measurements into hearing screening (using the same equipment), middle-ear and outer-ear disorders can be detected, thus allowing for rescreening rather than more expensive audiological referrals.

Abstract:

The continual exposure of outer hair cells (OHCs) to thermal noise causes vibrations in resonant frequency. As these vibrations are backprojected, they should be recordable as audiofrequencies in the outer ear canal. But even though they are likely to be amplified in some areas by clustering in terms of the chaos theory, they cannot be picked up in the outer ear canal by currently available recording technologies. Conditions change in the presence of pathology, e.g. loss of OHCs and fibrous replacement: Clusters grow in size and amplitudes become larger so that the vibrations can be picked up

Abstract:

Diseases of the outer and middle ear (Otitis externa and Otitis media) are a frequent clinical problem which is mostly approached in the wrong way. We believe that the approach to a diseased ear in dogs or cats by practicing veterinarians in our country is most often incorrect. Namely, the conventional approach to inflammation of the outer ear is narrowed down to cleaning the ear, usually with cotton wool and hydrogen peroxide, and then by applying ear drops for veterinary or human use over the next few days. A somewhat more conscientious approach implies treatment using antibiotics, topical a

The sounds heard by the human ear change from mechanical acoustic signals to electrical signals which are transmitted by the auditory nerve to the brain. The process of hearing certainly cannot be separated from the human hearing organ, namely the ear.The ear consists of three basic parts, namely the outer ear, middle ear and inner ear. Each part of the ear works with a specific task to detect and interpret sounds. The main function of the outer ear is to collect and connect sounds to the external acoustic meatus. The middle ear consists of 3 bones (ossicles) which will amplify the pressure 20

The observable morphological features of the outer ear are used in criminal investigations.

It is often found in burglary cases (breaking into the home or workplace). Although the unique structure of the ear and its usefulness in identification has been recognised by researchers, there are very few studies in which its uniqueness is stated with certainty.

Venous blood samples were obtained before and after the operation for bacteriologic analysis. Smear cultures were also obtained from the pressure dressing

Abstract:

This work addresses challenges related to camera 3D localization while reconstructing a 3D model of an ear. This work explores the potential solution of using a cap, specifically designed not to obstruct the ear, and its efficiency in enhancing the camera localization for structure-from-motion (SfM)-based object reconstruction. The proposed solution is described, and an elaboration of the experimental scenarios used to investigate the background textures is provided; data collection and software tools used in the research are reported. The results show that the proposed method is effective, an

Aim of study: This study assesses acute stress by measuring, through infrared thermography in summer and winter, the temperature of the eye, outer ear, inner ear and nose in 40 fattening rabbits before and after handling.Area of study: Seville (Spain).Material and methods: Body thermographic temperatures were recorded during a 38-day fattening period twice weekly and twice a day, before and after the handler held the rabbits in their arms for one minute. Ambient temperature and relative humidity were also recorded, and their influence on body temperatures was assessed. For each anatomical part

Abstract:

Morphology of the Inner Ear in Mammals with Different Ecological Peculiarities in OntogenyThe inner ear is the first to form, as the core, phylogenetically most ancient formation of the peripheral auditory system both in phylogenesis and in ontogenesis. As the development of the inner ear continues, the other parts of the peripheral auditory system of different evolutionary age start to be formed, and the outer ear is the evolutionary youngest among them. All parts of the peripheral auditory system are multicomponent formations. As opposed to the outer and middle ears, which are characterized

Abstract:

The temporal bones of an individual with documented unilateral Meniere's disease were prepared for light and electron microscopy. a morphometric analysis was performed on hair cells, spiral ganglion cells, dendritic fibers in the osseous spiral lamina, afferent and efferent endings, and afferent synaptic contacts. In the ear with Meniere's disease, we found hair cell damage, including disruption of the cuticular bodies and basalward displacement of some outer hair cells. There was no significant difference in the number of hair cells or spiral ganglion cells on the two sides. There was a signi

Сложности выявления подобных состояний обусловлены низкой настороженностью врачей в связи с тем, что изолированные аномалии среднего уха являются достаточно

Abstract:

Introduction. The transfer function of the outer ear is an important characteristic of the hearing organ, determined by the acoustic properties of the auricle and the external auditory canal, their shape and size. The acoustic impedance of the eardrum is also likely to matter. The frequency characteristics of the transmission function of the outer ear must be taken into account when choosing individual noise protection devices and when prosthetics of the hearing organs. Measurements of the sound pressure distribution along the auditory canal carried out by various researchers with a probe micr

Abstract:

Abstract Earwax, also known as cerumen, is produced by secretions from the apocrine and sebaceous glands located in the outer third of the cartilaginous part of the ear canal. Ear wax or cerumen is an omnipresent substance found in every individual. It protects from infections and other ailments to the outer and middle ear. The production and extrusion of this substance go unnoticed in most individuals. However, it assumes significance when it accumulates in the ear canal, prompting concern among audiologists, ENT physicians, and dermatologists. In addition, the lack of earwax in children due
