Dacryocystorrhinostomia műtétek során eltávolított könnytömlőminták szövettani elemzése

Abstract

Abstract: Introduction: Endonasal dacryocystorhinostomy (EDCR) has good results. Aim: To perform a prospective histological investigation of the removed lacrimal sacs’ walls. Method: Between 2016 and 2017, we carried out 21 operations in two groups: inflammatory (11 patients) and non-inflammatory (10 patients) lacrimation groups. The mean age was 60.5 years. Histological samples were investigated after staining them with hematoxylin-eosin. Results: In the non-inflammatory group, histology revealed the incipient metaplasia of the ciliated goblet cells. In the lacrimal sac’s wall, there is a chronic inflammation with mucinous metaplasia of the serous glands. In the inflammatory group, the metaplasia of the ciliated goblet cells is more pronounced. Chronic fibrotic inflammation destroys the lacrimal sac’s wall, which is dilated, ruptured. The mucinous metaplasia of the serous glands is pronounced. Conclusions: The results of histological investigations of the lacrimal sacs removed in the course of EDCR are much alike in the inflammatory and non- inflammatory groups.
