¸ñÀû: Although it is well known that Cisplatin is associated with ototoxicity, there is still a lack of knowledge concerning Cisplatins ototoxicity for head and neck cancer in Asian population. The objectives of this study is to find the incidence of ototoxicity and the dose of Cisplatin that causes ototoxicty in Japanese population ¹æ¹ý:The distortion product otoacoustic emission (DPOAE) was measured 1 week after each administration of cisplatin in 43 (32 men) japanese head and neck cancer patients. °á°ú:The incidence of ototoxicity detected by DPOAE was 68.2%. The averaged DPOAE value significantly decreased in patients who received more than 200 mg/m2 of Cisplatin. °á·Ð:Cisplatins ototoxicity was detected at lower cumulative dose in Japanese head and neck cancer patients than that previously reported in Caucasian patients. The result of this study could be explain with genetic variability.
