Abstract

Scientific and technical progress of modern surgical treatment of foot pathology poses new diagnostic tasks for radiologists. Opening of the functional MSCT (fMSCT) of the foot with weight-bearing significantly changed the treatment protocol of patients with acquired foot deformities.

Purpose: to conduct a comparative analysis of the angular parameters on x-ray images anc weight-bearing fMSCT images of the foot in patients with acquired adult flat feet.

Materials and methods: 45 patients (88 feet) were examined, who underwent x-ray examination of the foot with weight-bearing and weight-bearing fMSCT of the foot. On the received images were examined angular indicators of a foot and was carried out statistical comparison of the received results.

Results: after processing the measurement data of fMSCT and x-ray examination it was found that statistically significant differences in the standard definition of the angular parameters of the foot is not determined. To compare the values obtained by radiographic method and fMSCT was used paired Student's t-test. To determine the presence or absence of dependence of the difference of measurements obtained by the two methods from the average values of these measurements were constructed graphs of Bland-Altman. Evaluation of the longitudinal arch angle of the foot showed that all measurements are within the 95% predictive interval. The index of the calcaneal inclination angle, the individual values of the difference were outside the borders of the 95% predictive interval, but do not depend on the measurements.

Conclusion: comparative analysis showed the statistical insignificance of differences in the average values of individual angular indicators measured in the two groups (radiography and fMSCT) The data obtained in the course of the study allow us to assert the possibility of using the fMSCT of the foot with the load as a modern reliable method for assessing the angular parameters of the foot in order to determine the degree of flat deformation.

Abstract:

Methods of beam diagnostics play an important role in examination of patients with dental anomalies. Reliably establish dental anomaly is possible due to radiological examination. However, according to orthopantomography not always possible to identify the true cause of the anomaly, correct localization of abnormal tooth, preservation of periodontal ligament. All this leads to an incorrect treatment planning and the occurance of complications; in this regard all of our patients underwent addition cone-beam computed tomography Under our observation were 60 patients aged 15-30 years with a complex form anomaly of the position and the eruption of teeth. Half of patients had an anomaly of upper canines, remaining patients, the anomaly of upper premolars, canines and premolars in the mandible. The main cause of anomalies of teeth was due to lack of space in the dentition, less abnormalities were associated with the presence of obstacles in the way of the eruption, with congenital abnormalities of the maxillofacial region.

Possibilities of orthodontic and surgical interventions are limited and therefore it is very important accurate and reliable diagnosis of abnormalities. Cone-beam computed tomography allows to obtain all necessary information about the position of the tooth in the bone, its structure, shape, spatial relationship with roots of adjacent teeth and important anatomic structures, which makes it possible to properly plan for the further treatment strategy and reduce the risk of possible complications.

Abstract:

Aim: was to increase efficacy of diagnostics of oculomotor muscles injury in pre- and postoperative period with use of multislice computed tomography (MSCT).

Material and methods: for the petiod 2015-2016, 63 patients with maxillofacial trauma were admitted to the I.M.Sechenov hospital, within 24-48 hours after injury (55 males and 8 females, aged 18-59 years). All patients underwent MSCT of facial skeleton at the day of admittion and on 7-10 day after surgical treatment. Patients examination was made on 640-slice CT scanner and was added by multiplannar and 3D-reconstruction

Results: preoperative MSCT revealed oculomotor muscles injury in 29 patients (46%). Muscles injuries were presented with herniation into the maxillary sinus (n=20, 32%), damaged lateral, inferior and medial muscles by small bone fragments (n=17, 27%), unilateral thickening of muscles in 13 patients (21%).

Postoperative MSCT revealed oculomotor muscle damage caused by incorrectly implantation of prostheses of inferior orbital wall in 7 cases (11%).

Conclusion: MSCT is the modality of choice in pre- and postoperative diagnostics in patients with oculomotor muscles injury. MSCT provides the effective diagnostic solution in prevention of possible ocular movement impairment.

Abstract:

Aim: was to estimate possibilities of the CT in patients with anomalies of dental system and asymmetric jaws and to offer a protocol analysis of CT data.

Materials and Methods: 100 patients with anomalies of dental system were examined. They were divided into 4 groups:

- 22 patients with II class without asymmetry of jaws (22%)

- 8 patients with II class with the asymmetry of jaws (8%)

- 52 patients with III class without asymmetry of jaws (52%)

- 18 patients with III class with asymmetry of jaws (18%)

At the stage of preoperative planning, computed tomography was performed. CT protocol of jaws symmetry estimation was developed.

Results: with the help of developed СТ protocol, asymmetry of the maxilla was determined in 11 patients (11.0%): 5 patents (5.0%) with II class, 6 patients (6.0%) with III class. The number of patients with signs of asymmetry of the mandible of II class was 9 patients (9.0%), III class — 13 patients (13.0%). Obtained measurements allowed to analyze degree of asymmetry and calculate required excision and moving of jaws. For planning of surgical stage, CT data of all patients was uploaded into special program «Surgicase CMF».

Conclusions: CT gives possibilities to estimate the anatomy of the facial skeleton and its symmetry; that allows to make plan of further orthognathic surgery.

Abstract:

The work consists of 45 patient’s radiodiagnostics data: operation sinus-lifting has been executed before dental implantation to complete missing volume of bone fabric of maxilla alveolar process.

The analysis of cite data has shown an inefficiency of traditional ortopantomography and advantages of three-dimensional computed tomography in assessment of spent treatment.

Abstract:

Aim: was to estimate ultrasound signs of placental insufficiency in women whose pregnancy was the result of extracorporeal fertilization (ECF) and embryo replanting.

Materials and methods: the study involved 84 women who became pregnant as a result of ECF and replanting embryos. Terms of pregnancy were 18-40 weeks. Age of women was from 24 to 46 years. Ultrasound examination was performed by standard methods recommended for pregnant women, with an estimation of basic fetal metric parameters and their compliance with the term of pregnancy, the heart rate of the fetus, the degree of maturity of the placenta, thickness, location and sonographic features of the placenta (calcifications, cysts, heart attacks, expand the intervillous space varying degrees of severity) the quantity and quality of amniotic fluid.

Results: during ultrasound of women whose pregnancy was the result of ECF and embryos replanting, in 38 (35.6%) patients pathological changes in the placenta were diagnosed. It is evident in discrepancy of placenta maturity for a full-term pregnancy The combination of 3 or more of features identified during the ultrasound examination may indicate the development of placental insufficiency in women after ECF. Ultrasound features include: the degree of maturity mismatch placenta given gestational age; the thickness of the placenta; violation of utero-placental or fetus-placental blood flow; fetal growth retardation; amount of water.
