The study was aimed to assess the diagnostic values of the multislice computed tomography with 3d-reconstruction in diagnostic of mastoiditis. The presented study was not linked to any registered research topic. With the help of MSCT method, we examined patients at the following bases: 1. Department of Radiation Diagnostics, Radiation Therapy and Radiation Medicine ONMedU. 2. Center for reproductive and rehabilitation medicine (University Clinic) Odessa National Medical University.Most surveys were conducted for operative and conservative treatment. We performed 50 studies. Men accounted for 52% (26 patients), women 48% (24 patients). The patient’s age ranged from 18 to 90 years. The examination of the temporal bones was performed on a 16-slice computed tomography machine TOSHIBA Aquillion, Japan. Scanning parameters: scanning in 3 planes, thickness from 1 mm to 5 mm. The patient’s head is fixed to exclude dynamic artifacts. When analyzing MSCT images using bone and soft tissue modes of 3D-reconstruction, measure bone density and density of the mastoid process their content using the program Efilm. The criteria for evaluation is sufficient pneumatization of mastoid cells, cell density on the mastoid, lack of content and pathological inflammatory changes in mucosal cells. All 50 patients examined with multislice computed tomography were divided into 6 groups. Patients were divided into 2 groups according to the duration of the inflammatory process. The first group included 23 patients (46%) with acute mastoiditis. The second group included 15 patients (30%) with chronic mastoiditis. The third group included 3 patients (6%) with post-traumatic mastoiditis. Were formed 2 groups with complications of mastoiditis. The fourth group included 4 patients (8%) with external cranial complications: labyrinth, hearing impairment, paralysis of the facial nerve. The fifth group included 1 patient (2%) with intracranial complications: the spread of an infection in the brain that causes meningitis, encephalitis, abscess of different parts of the brain, phlegmons in the neck region. Sixth group – control. The sixth group included 4 patients (8%). The control group was formed from patients who were sent for examination and found to be healthy. Diagnostic studies performed by a 16-slice computed tomograph TOSHIBA Aquillion, Japan, it was possible to obtain a high-quality image of the soft tissues of the mastoid, to determine the localization and density of pathological formations. The possibility of multislice computed tomography with 3D-reconstruction allows us to estimate the state of bone tissue of the temporal bones, including the detection of purulent melting of the bone, to determine the density of pathological content and pneumatization of the cells of the mastoid, which is the most informative in patients with acute and post-traumatic mastoiditis. Due to the method of multislice computed tomography, the quality of differential diagnostics of the peculiarities of the structure of the mastoid with inflammatory and dystrophic phenomena in the mastoid was improved, and differential diagnostic criteria for inflammatory diseases of the middle ear and the optic nasal sprout were developed. High resolution and high-quality three-dimensional reconstruction allowed the optimal and short-term to choose a successful conservative therapy scheme, to determine and plan the volume and mode of surgical intervention. Surveys that were performed in a dynamic, helped to determine the effectiveness of conservative therapy and surgical intervention, prevented the occurrence of complications.
