METHOD OF DYNAMIC MULTI-SPIRAL COMPUTED TOMOGRAPHIC DIAGNOSTICS OF OTOSCLEROSIS AFTER TREATMENT IN PATIENTS AFTER STAPEDOPLASTY Russian patent published in 2012 - IPC A61B8/13 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to radiodiagnostics and otolaryngology, and can be used for post-operative diagnostics of patients with 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 prosthesis is reduced in comparison with norm or volume of movements of stirrup prosthesis is absent, otoscxlerosis is diagnosed.

EFFECT: method makes it possible to increase accuracy of diagnostics of otosclerosis in patients after stapedoplasty and determine indications for reoperation.
