A more aggravated condition has been dissected by Witzel (in the Rostock Collection). Behind the cleft in the upper lip was found a median division of the premaxilla, each half of which was firmly united to the adjacent superior maxilla. The vomer was single, but broader than usual, and the palate cleft throughout; the two halves of the nose were bounded internally by separated plates of the divided cartilaginous nasal septum. There was also a defect of the frontal bone giving rise to a meningocele. This flattening of the nose, combined with separation of the anterior nares, gave such an appearance to the face as seemed to warrant the term “dog’s nose” (Doggennase) which has been applied to it.[15]
Facial Clefts (German, “Schräge Gesichtsspalte”).
