  • Abstract
  • Look Inside

 A clinicopathological study was conducted on the changes that occur in the middle ear ossicles affected with middle ear cholesteatoma. The results were as follow:

 (1) The degree of bony changes does not necessarily agree with the severity of the disease. (2) Changes appeared to be the strongest in the incus. (3) That the ossicles had been exposed to mechanical pressure mainly due to vascular congestion rather than simple inflammation was evidenced by the way in which atrophic changes were seen in the bones and their invironment. Consequently, in the operation of cholesteatomata the question that whether or not the middle ear ossicles should be removed completely should be a subject of further study.
