SU957875A1 - Method of investigating air exchange of maxiallary sinus at maxiallary sinusitis - Google Patents

Description

one

The invention relates to medicine, namely to otolaryngology.

There is a known method for studying airflow: on the maxillary sinus and sinusitis by measuring the pressure in the sinus during ios breath 1.

However, the known method does not allow to determine the ventilation resistance of the maxillary sinus excretory orifice depending on the severity of the inflammatory process in the brain.

The purpose of the invention is to determine the ventilation resistance of the maxillary sinus excretory orifice depending on the degree of inflammation in it.

The goal is achieved by studying the air exchange of the maxillary sinus with sinusitis by measuring the pressure in the sinuses during iosal breathing, the distinctive feature of which is that both the pressure in the nasal cavity and the test sinus are measured during inspiration and expiration

The pressure of the opening of the maxillary sinus is reduced.

The method of investigation of the ventilation resistance is carried out using a two-channel instrument with a recorder.

The drawing shows a down-channel device with a recorder.

The device complies with the underwater tube 1 connected to the sensitive bellows 2,

10, the translational oscillations of which are amplified in amplitude by means of the lever mechanism 3 and through the recorder 4 are recorded on the chart tape 5 by two slimes. Pressure is recorded in the lower canal in the maxillary sinus, and in the upper channel - pressure is recorded in the nasal cavity. The Lenta is set in motion by the electric motor 6 through the gearbox 7.

When registering the air pressure in the maxillary sinus and the nasal cavity on the diagram sheet, we get two synchronous 395,787 sinusoids, Amtishta and each of them corresponds to the air pressure in a particular cavity during inhalation and exhalation. For the valve, the shuin resistance of the inlet orifice of the upper sinus and airflow is taken as the difference between the pressure differences in the cavity, the nose and in the maxillary sinus. This is done by measuring the magnitude of the amplitudes using an emigrant compass and calculating the races. For normal resistance (I st.) They take pressures from 0 to 6 hPa. Higher ventilation resistance (II st.) Ranges from 7 to 25 hPa. High ventilation resistance (III st.) Corresponds to a pressure of more than 25 hPa. The method is as follows .., After filling the device with a chart tape and chart recorders it is connected to the network, and by turning on the tape mechanism, the recording accuracy is checked. Then the outflow fitting of the device, corresponding to the lower recording channel, is connected to a drainage tube located in the maxillary cavity. Outlet port of the upper recording channel is connected to the tube, which is located in the lower nasal passage. The tube located in the nasal cavity is perforated for a better passage: air flow. An important condition for an objective assessment of the resistance of the ventral opening of the maxillary sinus is a thorough pre-flushing of the sinus under study and the nasal toilet. PRI me R. Patient L., while simultaneously determining fluctuations in air pressure in the nasal cavity and in the maxillary na3joce. The magnitude of pressure fluctuations in other surgery in the nasal cavity is 32 hPa, and in the maxillary sinus - 14 gPA. Thus, the sacristy, which is the magnitude of the vent resistance, is 18 hPa. After the performed operations - but with the resection of resection of the nasal septum and the subsequent partial resection of the hypertrophied anterior anterior end of the middle nasal shell - the range of pressure fluctuations in the nasal cavity and maxillary sinus turned out to be the same. Consequently, the ventilation resistance of the 5-10 outlets is zero, which, by compctBBimo, is an ideal option for air exchange in the maxillary sinus. The simultaneous determination of the absolute value of pressure in the nasal cavity and maxillary sinus and the calculation of their difference makes it possible to determine with sufficient accuracy the ventilation resistance of the sinus excretory orifice under physiological conditions that do not require standardization of individual conditions. The method is characterized by sufficient information content by objectivity, is relatively simple, does not require any special training, and with sufficient skill can be carried out by a nurse. The method is used to evaluate the air exchange of the maxillary sinuses in acute and chronic sinusitis. A total of 219 studies were conducted in 168 patients. The method is sufficiently accurate, documentary, makes it possible to monitor the change in ventilation of the resistance of the maxillary sinus excretory orifice in the process of treatment of sinusitis, and thus add additional information on the degree of sinusitis recovery, as well. also raise the issue of timely surgical treatment. The invention of the method of investigating the air intake of the maxillary sinus with sinusitis by measuring the pressure in the sinus during nasal breathing, is distinguished by the fact that, in order to determine the ventilation resistance, the output of the maxillary sinus opening is simultaneously measured according to the severity of the inflammatory process. The nasal cavity and in the test sinus on inhalation and exhalation, and on the basis of the pressure difference, determine the internal resistance of the orifice of the maxillary sinus.
