METHOD OF DINAMIC MULTI-SPIRAL COMPUTED TOMOGRAPHIC DIAGNOSTICS OF OTOSCLEROSIS

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to otolarytngology and radiodiagnostics, and is intended for early diagnostics of otosclerosis. 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 stirrup stapes in oval window niche.;EFFECT: method makes it possible to increase accuracy of diagnostics of otosclerosis;2 ex
