Abstract

There is very little information available on the racial distribution of otosclerosis. The incidence of otosclerosis in South India among Dra-vidians is high. The incidence of otosclerosis among all patients with hearing loss seen at the Christian Medical College Hospital, Vellore, in 1962 and 1963 was 30% and 31% respectively. The South Indians are not the original inhabitants of India. They are migrants from Eastern Europe and the Middle East. Comparisons were made with other studies on otosclerosis as regards the incidence, sex and age distribution, the onset and duration of hearing loss and clinical features of otosclerosis in this region.

Über die Verbreitung der Otosklerose in bezug auf Rassen ist sehr wenig Material vorlianden. In Südindien ist die Anzahl von Otoskleroscallen bei den Draviden hoch. Bei den Patienten mit Hörverlust, die im Christian Medical College Hospital in Vellore in den Jahren 1962 und 1963 untersucht warden, betrugen die Otosklerosefalle 30 bzw. 31%. Die Siidindier sind nicht die ursprÜng-lichen Einwohner Indiens, sondern von Ostcuropa und dem Mittleren Osten eingewandert.

Vergleiche mit anderen Untersuchungen über Otosklerose warden vorgenommen in bezug auf ihr Vorkommen, Verteilung auf Alter und Geschlecht, Beginn nnd Dauer des Hörverlustes und die kliniscben Merkmale der Otosklerose in diesem Gebiet.
