Clinical and morphological aspects of laryngeal cysts.

摘要: To our knowledge only a few defined studies have been carried out on laryngeal cysts. These cysts represent mixed group of benign lesions that can cause diagnostic and therapeutic difficulties. The aim this study was to characterize their histological structure localizations in the larynx as well discuss theories about genesis. Between 1973 1996, 342 were treated at Phillips University Marburg, while from 1990 74 Justus Liebig Giessen. In all, 416 by endolaryngeal microsurgery. All clinical charts reviewed retrospectively surgical specimens examined histomorphologically. Findings showed 58.2% located glottic area 18.3% ventricular folds. remainder aryepiglottic fold (2.2%) interarythenoid region (0.7%). Two congenital also treated. Approximately 56% lined squamous cell epithelium, 37% respiratory epithelium 7% oncocytic epithelium. general, found be collection inhomogenous different histogenetic origins with diverse symptoms related site size. On basis investigations, new classification established concerning genesis development subdividing into cysts, retention inclusion
