Die dysontogenetischen, medianen Oberkieferzysten

Abstract

Nasopalatine duct cysts, median palatine cysts and nasoalveolar cysts belong to the developmental cysts of the upper jaw. They are situated at the midline in the fusion areas of embryonic facial processes and for this reason are known as "fissural cysts". They are, therefore, not of odontogenic origin and, on account of their relationship to the mouth, the nose and the nasal cavities, are of practical relevance to the otolaryngologist. The various clinical symptoms and the histological findings are described, and a review of the literature is presented.
