Abstract
The levels of isotopes of calcium, iodine, magnesium, copper, chlorine, and sodium in stapedes and cortical bone from otosclerotic and non-otosclerotic patients were deternined by neutron activation analysis. No n significant differences were found in the levels of calcium, iodine, magnesium, chlorine, or sodium in otosclerotic stapedes or cortical bone when compared with the levels in the respective control tissues. Simi- s larly, no difference was found between copper levels s in otosclerotic and normal stapedes.
