摘要：

A new technique for removing the soft tissues from middle ear ossicles to prepare them for scanning electron microscopy is described. The technique involved use of a solution of hypochlorite. The bony surface of normal ossicles was studied as a control group after preparation by the technique and no morphological distortion was observed. Ossicles eroded by cholesteatoma were then studied, and we propose that the erosion occurs in three stages; pumicing, pitting and cavitating. The mucoperiosteum of normal ossicles and otosclerotic foci were also studied.
