Spend the amount of thickening of the masticatory muscles using ultrasound at a frequency of 7.5-10 MHz and power of sound 40-60 dB by the formula
< / BR>where a is the initial thickness of the muscle; the muscle thickness at maximum contraction, and if the percentage reduction is less than 25% diagnose inflammatory contracture. The method is effective, simple, safe for use and is an auxiliary examination method. The invention relates to medicine, namely to the ultrasonic diagnosis in surgical dentistry.A known method for the diagnosis of inflammatory contractures of the lower jaw using clinical examination of the patient ("dental Surgery" Ed. by Robotboy T. G., 1990, page 26). The disadvantages of this method is that it is subjective and does not allow full reliability to establish changes in the muscle tissue of the masticatory muscles in the inflammatory process.The invention is directed to the solution is achieved with the help of ultrasound examination of the masticatory muscles and determine their percentage of thickening by a special formula. Inflammatory contracture is diagnosed when the decrease in this indicator is less than 25%.The method is as follows.The patient is seated next to an ultrasonic analyzer SIM 7000 CFM CHALLENGE. The doctor who did the diagnostics, is located opposite. The study is carried out using a microconvex probe with a frequency of 7.5-10 MHz and power of sound 40-60 dB. The sensor is applied ultrasonic gel. The sensor is installed in the projection of the masticatory muscles in such a way that the sector scan is parallel to the course of the muscle fibers. During the research, analyze the structure of the masticatory muscles, their exogenous density, presence of pathological inclusions.At the first stage in the projection of the middle third of the muscle install the sensor determines the starting thickness of the masseter muscle.In the second stage, carry out the thickness measurement of muscle while minimizing them, and both figures are determined on both sides.To further determine the percentage of thickening of the muscles by the formula

SUBSTANCE: method involves examining eyeball and retrobulbary space by means of ultrasonic scanner. Ultrasonic gray scale orbit scanning is applied in real-time mode to determine ultrasonic eye reposition. Positive ultrasonic eye reposition is determined and normal state is diagnosed when recording mobile unchanged shape and free oscillation orbit tissue movements. Changes in shape, contours and size of the eyeball and immobility of orbit tissues being recorded, negative ultrasonic reposition is determined and solid full-tissue neoplasms and structures are diagnosed to occur.
EFFECT: high objectivity of received data; accelerated examination; high accuracy of differential diagnosis.
SUBSTANCE: method involves applying polypositional ultrasonic scanning techniques in real time mode. Echo pattern of thinned fibrous ring to 1 mm or its rupture or anteroposterior vertebral canal size reduction by more than 4 mm, vacuum phenomenon, nerve radix compression with asymmetry more than 2 mm is to be recognized.
EFFECT: high accuracy of non-invasive, non-ionizing primary diagnosis method.
FIELD: medicine, surgery.
SUBSTANCE: one should carry out virological testing patient's blood serum and hepatic bioptates. At detecting TTVDNA and HGVRNA it is necessary to perform ultrasound survey, and at availability of biliary sludge one should conclude upon early stage of cholelithiasis.

SUBSTANCE: method involves measuring uniform ampoule-like enlargement area of nerve trunk smoothly transforming itself into hypoechogenic formation with smooth distinct outline of no longitudinal striation echo-structure in longitudinal projection and enlarged rounded hypoechogenic region with changed echo-structure without granularity in transverse projection observed in visualizing the nerve trunk enlargement in transverse scanning mode. Area of zone proximally located 3-4 cm far from lesion region. Asymmetry coefficient is determined as ratio of the values. The coefficient value being greater than 2.4, terminal neuroma is diagnosed witnessing complete nerve rupture. When visualizing the single side nerve boundary enlargement in both projections with hypoechogenic zone of disturbed echogenicity structure and retained nerve segment unchanged at this level under asymmetry coefficient value being less than 2.4, lateral neuroma is diagnosed to be the case witnessing partial nerve rupture. When finding zone of linear striation echo-structure in longitudinal scanning mode and showing echo-structure granularity in transverse scanning mode not greater than 1.7 times proximal zone area 2-6 months later after the operation, fascicle nerve structure recovery in suture vicinity is considered to take place. Ampoule-like enlarged, hypoechogenic formation having partially disturbed inhomogeneous heterogeneous structure 1.7 times greater than proximal zone area being found within this period, intensive nerve trunk connective tissue elements proliferation and intratrunk neuroma is proved to be the case.
EFFECT: high accuracy in determining nerve injury degree; enhanced effectiveness in controlling postoperative nerve fiber recovery.
