  • Title: Degeneration of the organ of Corti following intravenous administration of cisplatin.
    Author: Laurell G, Bagger-Sjöbäck D.
    Journal: Acta Otolaryngol; 1991; 111(5):891-8. PubMed ID: 1759575.
    Abstract:
    The development of acute morphological changes in the cochlea was studied in guinea pigs given one intravenous high-dose injection of cisplatin. In the light microscope three major stages of degeneration in the organ of Corti could be recognized: 1) an initial swelling of the Hensen's cells and protrusion of the Deiters' cells into the space of Nuel enclosing the outer hair cells, 2) a gradual degeneration of the outer hair cells together with a vacuolization in the region of the base of the inner hair cells, 3) a collapse of the Reissner's membrane and the entire organ of Corti with different degrees of damage to the inner hair cells. Sporadic bulging of the marginal cells of the stria vascularis into the endolymphatic space could be observed 4 days after injection.
