CAUSES OF FAILURE OF ENDONASAL ENDOSCOPIC DACRYOCYSTORINOSTOMY IN THE SURGICAL TREATMENT OF CHRONIC DACRYOCYSTITIS

Abstract

This article presents the results of research the factors leading to unsuccessful results of endoscopic dacryocystorhinostomy (EDCR) in the treatment of chronic dacryocystitis.The retrospective study included medical records of 55 patients (55 eyes) diagnosed with chronic dacryocystitis who underwent EDCR between 2018 and 2022. The surgical intervention was performed using a videoendoscopic complex “Fieger Endophtix”. In the postoperative period (3-6 months) the overall success rate for the surgery was 61,8%. In 15 patients (27,3%) was received partial success and in 6 patients (10,9%) the result was unsuccessful. The parameters that correlated significantly with failure were coexisting diseases as diabetes mellitus, hypertrophy of the nasal mucosa, allergy to medications, etc. Thus, EDCR is technically simple and safe surgical procedure with shorter duration. Among the risk factors leading to unsuccessful outcome are such coexisting diseases as diabetes mellitus, hypertrophy of the nasal mucosa and allergy to medications.
