Otosklerotische Veränderungen im Bereich der Mittelohrschleimhaut
Otosclerotic changes in middle ear mucosa
Samples of 11 patients with otosclerosis were taken from the middle ear mucosa. Within the subepithelial layer dense bundles of kollagen fibers and microossification along these bundles could be shown ultrastructurally. Between the bony frontier and the mucosal layer capillary defects caused bleeding into the tissue. The epithelial layer and the adjacent basement membrane also showed slight morphological changes.
