Clinical Trial
[The "Muenster classification" of high frequency hearing loss following cisplatin chemotherapy].
Slight high frequency hearing loss following cisplatin chemotherapy can be proof of an ototoxic effect even when hearing ability is not yet clinically affected. To answer scientific questions, such as the relationship between cisplatin ototoxicity and drug regime or individual tolerance, early detection of ototoxicity and a classification relating to intensity and the affected frequencies are required. A search for relevant literature resulted the WHO-classification (1991) describing clinically relevant hearing loss and two high frequency hearing loss classifications published by Khan et al. (1982) and Brock et al. (1991). Their application is compared to a new, proprietary classification. ⋯ The Muenster classification is a suitable new basis for scientific questions concerning cisplatin ototoxicity. It detects hearing loss earlier and maps progression of hearing loss more precisely than the existing high frequency classifications (Khan et al. and Brock et al.).
