Kirov Military Medical Academy of the Ministry of Defense13122020391S22122328082020Copyright © 2020, Naumova L.V., Poritskiy U.V.2020The analysis of objective research data obtained during the examination of patients suffering from chronic dacryocystitis is presented. The importance of modern as well as traditional methods was defined. It was shown that the modern diagnostic method - lacrimal endoscopy is indicative and informative, not only with confirmed chronic dacryocystitis but also in the absence of pathological changes in the lacrimal ducts in patients of the control group. The aim of the studi was to improve the quality of diagnosis of chronic dacryocystitis. There are traditional methods for diagnosing chronic dacryocystitis. They were also used in patients of the control group (without pathology of lacrimation) and in patients with chronic dacryocystitis. Refers to them sounding of the lacrimal ways, washing them with lacriminal cannulas, slit lamp biomicroscopy, color nasal lacrimal test 2% fluorescein sodium solution for its implementation, lacrimal endoscopy with lacrimal endoscope. A total of 20 patients were examined. In the control group of patients, with the help of lacrimal endoscopy, the normal appearance of the mucous membrane of the lacrimal tubules, lacrimal sac, the nasolacrimal duct was determined. Active patency of the tear ducts was confirmed by a positive color nasal lacrimal breakdown. When performing endoscopy of the lacrimal passages in patients of the second group, the criteria for pathological changes in the lacrimal sac and nasolacrimal duct, characteristic for chronic dacryocystitis, are determined: hyperemia, the presence of detachable, grayish folds of the mucous membrane, whitish-gray membrane in the area of stricture. The preliminary diagnosis of chronic dacryocystitis was also confirmed by traditional diagnostic methods: color lacrimal-nasal functional test, diagnostic sounding. and lacrimal lavage, dacryocystography. As a result of the study, it was found that lacrimal endoscopy significantly expands the possibilities of diagnosing chronic dacryocystitis, confirms and complements the data of traditional research methods, allows you to see structural changes along the tear ducts, determines the degree and level of obliteration. The combination of traditional diagnostic methods and lacrimal endoscopy allows the surgeon to choose the most appropriate way of surgical treatment of this pathology.chronic dacryocystitislacrimal endoscopediagnosisflushingprobingdacryocystographyendoscopyхронический дакриоциститлакримальный эндоскопдиагностикапромываниезондированиедакриоцистографияэндоскопия[1.
