SU1519653A1 - Method of diagnosis of diseases of maxillary sinus - Google Patents

Abstract

This invention relates to otolon ringology. The goal is to improve the accuracy of diagnosis of diseases of the maxillary sinuses. The transducer is introduced into the oral cavity and fixed on a hard palate in the region of 5-6 teeth with the direction of the ultrasound beam to the lateral angle of the eye. Connect the transducer to the analyzer and record the appearance of the pulse reflected from the back wall of the sinus. The patient's head is tilted in the direction opposite to the sinus under study at an angle of 45 ° from the vertical position, followed by a slow inclination to the angle of 90 °. The face is gradually rotated upward by an angle of 30-45 ° relative to the horizontal position; 4 MHz. The method makes it possible to increase the diagnostic accuracy by 1.3 times, shorten the study time and eliminate radiation exposure.

Description

The invention relates to the field of us, namely to ultrasound diagnosis in otolaryngology.

The purpose of the invention is to improve the accuracy of diagnosis by examining the hard palate of the oral cavity in the region of 5-6 upper teeth.

The method is carried out as follows.

The patient is seated next to the ultrasound meter. The diagnosis doctor is opposite. The device for fixing the transducer is fixed on the frontal and chin of the patient's head, the transducer is inserted into the oral cavity and fixed on the hard palate in the region of 5-6 teeth with the ultrasonic beam directed to the lateral angle of the eye. Connect the transducer to the analyzer and record the appearance of a pulse reflected from the back wall of the sinus. Tilt the patient's head in the direction opposite to the sinus under study at an angle of 45 from the vertical position. Continuing to tilt slowly to angle 90, they gradually turn the face upward at an angle of 30-45 and achieve an alternate 1np impulse on the screen of the analyzer. Carrying out a series of slow turns of the face within an angle of 30-45 °, the maximum amplitude of this pulse is achieved. Analyzing the mutual arrangement of the impulses reflected from the posterior wall of the sinus, and the impulse that was additionally recorded, makes a conclusion on the location and form of the sinus lesion.

A test of the method and device was carried out with iiOMonibK) U.1 TD devices UD-10P and ECHO 11 equipped with special sensors. The transducer has a triangular prism shape with a cross section of 6x6x6 mm and a length of 12 mm. The frequency of operation of converters is 2, 3, 4. MHz. The pulse frequency is 0.5 kHz, the radiation power is 10 W / cm.

howling half of the face, body in the right half of the head. These events recur over the past two years. X-ray examination - Vulization of the lower part of the right maxillary sinus. With an ultrasound study but a known method, pathologists were not identified. An ultrasound study of the proposed method at a frequency of 2 MHz with the patient's head tilted to the left at an angle of 45 ° from the vertical and turning the face upward at an angle of 30 ° echogram revealed the presence in the posterior part of the sinus of a non-movable exudate. Postoperative diagnosis: cystic lesion of the posterior part of the right sinus.

Example 2. A patient was admitted to the ward with complaints of congestion in the left half of the nose, discharge from this half of the nose, recurrent headaches. X-ray examination did not reveal any abnormalities.

An ultrasound study by a known method revealed a small amount of exudate being moved. An ultrasound study of the proposed method at a frequency of 4 MHz with a head tilted at an angle of 90 ° and a 45 ° turn of the face, revealed the presence of a polypous sinus lesion. Postoperative diagnosis: left-sided chronic gai.oritis

polypous and purulent form. The site of attachment of the polyps is the posterior wall of the sinus.

Thus, the use of the proposed invention makes it possible to increase the number of correctly made diagnoses by almost 1.3 times, reduce the time spent on examining patients in the outpatient setting and the hospital, shorten the time of disability of patients, eliminate the biological hazards of X-ray examination and save the time of medical workers on diagnosis. about 1.5 times.
