METHOD OF DYNAMIC MULTI-SPIRAL COMPUTED TOMOGRAPHIC DIAGNOSTICS OF ADHESIVE OTITIS MEDIA

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to radiodiagnostics and otolaryngology, and can be used for diagnostics of adhesive otitis media. Performed is multi-spiral computed tomography with three-dimensional dynamic scanning with section thickness 0.5 mm and interval 0.25 mm in axial projection. Simultaneously performed is impact with probing audio signal, exceeding perception threshold by 15-20 dB, and with test frequency 1000 Hz on middle ear structures with 1 second interval for 4-5 seconds. Multiplanar and three-dimensional reconstructions are built. If it is determined that volume of movements of auditory ossicles and ligament apparatus of tympanic cavity is reduced in comparison with norm, adhesive otitis media is diagnosed.;EFFECT: method makes it possible to increase accuracy of diagnostics of adhesive otitis media.;2 ex
