Gerontological aspects of hyperostosis frontalis interna.
Authors discuss hyperostosis frontalis interna observed in a large number of aged persons, on the basis of age and sex distribution as well as its clinical and roentgenomorphological analysis. In various forms of the ossification of the frontal bone no significant difference was found between the localisation of hyperostosis and the clinical symptoms. On other hand, there is a direct correlation between the extension and severity of hyperostosis and the frequency of occurence of the associated symptoms (obesity, hypertension). They found the aetiological classification more adequate than the morphological categorization of Moore. Their cases are discussed 1. as partial phenomenon of the Morgagni's syndrome; 2. as independent alteration, showing no other symptoms; 3. as transitionary forms inserted between the two groups mentioned above. They discuss also the question of senile, compensatory hyperostosis frontalis interna. On the basis of the study of a large autopsy material they support the opinion that there is a direct connection of this form with old age.
