Cholesteatoma &tegment; tympani plate.

My father is a heart patient with stunt. He has got one ear deaf before 35 years. Recently he had puss coming out in the same ear. Endoscopic done & it shows two holes in the ear. CT scan says "possibility of left post operative status with recurrent CSOM, granulation (?Cholesteatoma) with rare function of assicular chain & tegment tympani plate should be considered" Doctor advised for laparoscopical surgery. He says nose inner bones are bent and there is no enough air that passes through nose to ear and the ear is not getting enough air. Another impression says " possibility of allergic rhino-sinusitis with DNS with septal spur towards right side should be considered " Doctor also there is a cyst of water that corroded the bone that is connecting the ear and the brain and as of now the westerly fluid is not affect the brain but this is a serious condition to treat asap. Since he is taking stunt tablets he is asking to stop aspirin kinds of for one week before he operates.
