摘要

為了解外耳道黴菌叢，是否受放射線照射的影響而改變，從接受放射線治療之頭頸部癌症病患40人，做了外耳道黴菌學研究，並與30位非癌症病患做比較。發現：(1)癌症病患之外耳道黴菌叢，”Candida”及”Aspergillus”要比非癌症群多，而且有正常的癌症病患，接受放射線照射後，兩側外耳道中至少有一側，由無菌變為有黴菌，而且都是伺機性黴菌”Candida”及”Aspergillus”。由此推測，頭頸部癌症病患在照射過程中，比較容易發炎的原因，除了外耳道皮膚之照射外傷外，黴菌性的有(1)癌症病患外耳道本來就異於正常的黴菌叢。(2)放射線照射後之黴菌叢改變。

A mycological study of external ear canals was performed in 40 patients with head and neck cancer to observe the radiation effect on the fungal flora in external ear canals. The control group consisted of 30 non-cancer patients. The findings were: 1. More Candida sp. And Aspergillus sp. Were noted in cancer patients than control group and C. albicans were also found, which didn’t exist in normal persons. 2. There were opportunistic fungal flora, Candida sp. and Aspergillus sp., in at least one side of external ear canals in 32.5% of the postirradiated patients who had aseptic external ear canals before the radiation therapy. The reasons we inferred that the patients with head and neck cancer during the radiation therapy were predisposed to otitis externa, in addition to radiation injury to the canal skin, were: 1. The different fungal flora in external ear canals of patients with head and neck cancer before the radiation therapy. 2. The changes of fungal flora after the radiation therapy.
