Ultrasonic and thermal imaging methods for diagnosing diseases of ENT organs.
Ultrasound diagnosis of the sinuses, TMJ.
Echoencephalography (Greek echo echo, echo + anat. Encephalon brain + Greek grapho write, depict; synonyms: ultrasound encephalography, neurosonography) is a method of examining the brain using ultrasound. The soft tissues of the head, bones of the skull, and brain tissue have different acoustic impedances and reflect ultrasound to different degrees, which is used for diagnostic purposes (see Ultrasound Diagnostics). E. allows to detect volumetric brain lesions (tumors, hematomas, abscesses, foreign bodies, etc.), hydrocephalus, intracerebral hypertension, cerebral edema. The method has no contraindications and can be applied in all cases when it is possible to ensure a snug fit of the ultrasonic sensor (probe) to the scalp.
The use of thermal imaging in medicine.
In modern medicine, thermal imaging is a powerful diagnostic method that allows you to identify pathologies that are difficult to control in other ways. Thermal imaging examination is used to diagnose at the early stages (before radiological manifestations, and in some cases long before the patient complaints) the following diseases: inflammation and tumors of the mammary glands, organs of the gynecological sphere, skin, lymph nodes, ENT disease, damage to nerves and blood vessels of the extremities, phlebeurysm; inflammatory diseases of the gastrointestinal tract, liver, kidneys; osteochondrosis and tumors
the spine. As an absolutely harmless device, the thermal imager is effectively used in obstetrics and pediatrics.
In a healthy person, the temperature distribution is symmetrical with respect to the midline of the body. Breach of this symmetry also serves
The main criterion for thermal imaging diagnostics of diseases. Symptoms of more than 150 diseases at the earliest stages of their occurrence can be recognized in areas of the body with an abnormally high or low temperature.
Thermography is a method of functional diagnostics based on registration of infrared radiation of the human body proportional to its temperature. The distribution and intensity of thermal radiation are normally determined by the peculiarity of the physiological processes occurring in the body, in particular both in the surface and in the deep organs.
Various pathological conditions are characterized by thermal asymmetry and the presence of a temperature gradient between the zone of increased or decreased radiation and the symmetrical part of the body, which is reflected in the thermographic picture. This fact has important diagnostic and prognostic value, as evidenced by numerous clinical studies.
There are two main types of thermography:
1. Contact cholesteric thermography.
Teletography is based on the conversion of infrared radiation from a human body into an electrical signal, which is visualized on the screen of a thermal imager.
Contact cholesteric thermography is based on the optical properties of cholesteric liquid crystals, which are manifested by a color change in rainbow colors when applied to thermally emitting surfaces. The coldest areas are red; the hottest are blue. Liquid crystal compositions applied to the skin, having a heat sensitivity in the range of 0.001 C, react to heat flux
by restructuring the molecular structure.
After considering various methods of thermal imaging, the question arises of how to interpret a thermographic image. There are visual and quantitative methods for evaluating the thermal imaging picture.
Visual (qualitative) assessment of thermography allows you to determine the location, size, shape and structure of foci of increased radiation, as well as tentatively assess the magnitude of infrared radiation. However, with a visual assessment, accurate temperature measurement is not possible. In addition, the rise in the apparent temperature in the thermograph itself is dependent on the sweep speed and field strength. Difficulties for the clinical evaluation of thermography results are that the rise in temperature in a small area is not noticeable. As a result, a small pathological focus may not be detected.
The radiometric approach is very promising. It involves the use of the most modern technology and can find application for conducting a mass preventive examination, obtaining quantitative information about pathological processes in the studied areas, as well as for assessing the effectiveness of thermography.

Ultrasonic and thermal imaging methods for diagnosing diseases of ENT organs.
- Lumbar puncture: technique, indications, significance in the differential diagnosis of diseases of ENT organs
In order to obtain cerebrospinal fluid for laboratory research and the introduction of drugs into the subarachnoid space, lumbar puncture is performed. Technique of carrying out a lumbar puncture It is better to perform a lumbar puncture in the supine position of the patient. During a puncture, the patient lies on his side, close to the edge of the bed, maximum bending of the spine (neck bent,
- RESEARCH METHODS OF ENT ORGANS
Methods of examination and endoscopic examination of ENT organs have a number of general principles. 1. The examinee is seated so that the light source and the table with the instruments are to the right of him. 2. The doctor sits opposite the subject with his feet to the table: the legs of the subject should be out. 3. The light source is located at the level of the right auricle of the subject at a distance of 10 cm from
- Inflammatory diseases of the ENT organs
The most common inflammatory diseases of the ENT organs are represented by the following nosological forms: nasal boil, acute otitis media, acute sinusitis, paratonsillitis, pharyngeal abscess, laryngeal tonsillitis, phlegmonous laryngitis. The clinical significance of these diseases lies in the fact that they can occur both in latent and fulminant forms, accompanied by serious complications.
- CLINICAL ANATOMY AND PHYSIOLOGY OF THE UPPER RESPIRATORY AND EAR. RESEARCH METHODS OF ENT ORGANS
Otorhinolaryngology is a science and practical discipline about diseases of the ear, nose, pharynx and larynx (abbreviated as ENT). Given the applied nature of the manual, it is advisable to provide the main content - a description of diseases - with information on the clinical anatomy, physiology and research methods of these organs. Since diseases of ENT organs are often interconnected with pathology nearby
- Intracranial Complications of Diseases of the ENT Organs
Otogenic meningitis, brain abscesses Develop in patients with a history of acute or chronic purulent otitis media or corresponding clinical manifestations from the ear. NP: Immediate transportation to the ENT department is required. In the course of transportation, symptomatic therapy may be necessary due to cerebral edema (Lasix 40 mg IM, prednisolone IV 60 mg), respiratory arrest.

- Features of ENT diseases in influenza
Flu otitis media In the case of influenza, otitis media can be nonspecific and can easily occur. In some influenza epidemics, otitis media is common, which occurs hematogenously as a result of exposure to the influenza virus or by spreading the virus from the upper respiratory tract through the auditory tube. Specific influenza otitis media is characterized by a hemorrhagic form of inflammation, expressed in a sharp expansion
