[Histological investigation of the walls of lacrimal sacs removed in the course of dacryocystorhinostomy]. / Dacryocystorrhinostomia mutétek során eltávolított könnytömlominták szövettani elemzése.

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.

[Otosclerosis. 2nd part. Diagnosis]. / Otosclerosis. 2. rész. Diagnózis.

Otosclerosis is a bone remodeling disorder affecting exclusively the human temporal bone which causes small bony lesions in the otic capsule. The symptoms depend on the location and the extent of the otosclerotic foci. Hence, clinically the most relevant sign is the conductive hearing loss due to the stapedial otosclerosis with fixation of the stapes footplate. In many cases, the specific anamnestic features, the age of presentation and usually the absence of tympanic membrane pathology can provide a strong clinical suspicion for otosclerosis. Although audiometric and imaging examinations and VEMP testing can confirm our preoperative diagnosis, the histolopathologic examination of the removed stapes footplate is the most accurate way to determine the diagnosis.
