The results were as follows:1) The number of cases with cholesteatoma was more than that of suppurative otitis media.The incidence of carcinoma was more often in these patients than in younger patients.2) The reasons the patients in this group visited to Kyoto First Red Cross Hospital were not only for hearing problems but also for others like facial palsies and severe otalgia.3) Gram negative rods were detected frequently from ear discharge before surgeries.4) The complications with these patients were more common than those with younger patients. It is better for us to take care of these complications and to treat them sufficiently, especially hypertensions and post operative vertigoes.5) The improvements of hearing thresholds after surgeries were possible if the cases were carefully selected. According to our results, it is reasonable to do surgical treatments to these patients more actively than before.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
