Abstract
Ototoxicity is one of the unwanted side-effects of a number of medical drugs. As ototoxicity appears to be most pronounced in the higher frequencies, it can be assessed at an earlier stage by using high-frequency audiometry from 8 to 20 kHz. We have investigated the precision of these measurements. In spite of inaccuracies of headphone positioning, which may influence especially the high-frequency thresholds, standard deviations for frequencies above 8 kHz were obtained that were nearly as small as for audiometry up to 8 kHz. Age-related reference curves for the higher frequencies are presented. The results on 100 ears of patients treated with platinum-derivatives show the importance of high-frequency audiometry for the early detection of ototoxicity. Certains médicaments ont un effet toxique sur l'oreille interne (ototoxicité). Cet effet se produit d'abord au niveau des hautes fréquences et peut ětre détecté plus töt par audiométrie dans les fréquences de 8 à 20 kHz que par audiométrie conventionnelle. Bien que la position des écouteurs sur la těte puisse influencer le seuil des hautes fréquences, nous avons obtenu des écarts-types presqu'aussi petits qu'avec audiométrie jusqu'à 8 kHz. Des courbes de référence en fonction de l'aˇge sont présentées. L'importance de l'audiométrie dans les hautes fréquences pour la détection précoce d'un effet ototoxique est démontrée à partir des résultats obtenus chez 100 malades traités par des dérivés du platine.Keywords
