During certain stages of mammalian inner ear development, small crystallized bodies which resemble otoconia may be found in the endolymphatic sac. In order to examine whether the endolymphatic sac plays any part in the process of degradation and dissolution of otoconia, we made an electron-microscopic examination on the endolymphatic sac of fetuses and adult guinea pigs injected with streptomycin sulfate (SM). In 30-day-old fetal guinea pigs we found miniature otoconium-like bodies (OLBs) in the endolymphatic sac and a giant OLB in the endolymphatic duct. In adult animals we found no otoconia in the endolymphatic sac following SM intoxication. However, the results suggested that both the dark cells of the utricle, as well as the non-sensory epithelium of the saccule, may be engaged in the absorption and dissolution of otoconia.
