Abstract (2. Language): 
A wide ranged different drugs have been proved to be ototoxic in the last 50 years. These are aminoglycosides, loop diuretics, local anesthetics, antineoplastic drugs and non-steroidal anti-inflammatory agents. In this study, probable ototoxic side effects of cisplatin, antineoplastic agent, with or without gentamyci n on the guinea pig's cochlea was evaluated light microscopically. Finally, it was found that nucleer loss and degeneration of hair cells in the bazal turn of cochlea as well the changes in spiral ganglion andnervef bers These degenerative changes were more severe in the group IV which on cisplatin and gentamycin combination as compared with group III which on cisplatin only. Thus, it was found that cisplatin and gentamycin combination may bemoreototoxic thatthe useofonly cisplatin. For statistically analysis, Wilcoxon Signed-Rank test was used. Cisplatin group (group III) was compared cisplatin-gentamycin group (group IV) and was statistically significant (p<0 . 001).

Abstract (Original Language): 
Son elli yılda çok sayıda ilacın ototoksik yan etkiye sahip olduğu bulunmuştur. Bunlardan en önemlileri; aminoglikozitler, loopdiüretikler, lokal anestezikler, antineoplastik ilaçlar ve non-steroidal antienflamatuar ilaçlardır. Çalışmamızda antineoplastik ilaçlardan cisplatinin tek başına ve aminoglikozidlerden gentamisin ile birlikte kullanımının guinea pig kokleasında olası ototoksik etkileri ışık mikroskopik olarak değerlendirildi. Bu çalışma sonucunda, kokleanın bazal kıvrımında tüylü hücre dejenerasyonu ve nükleer kayıp, spiral ganglion hücreleri ve sinir liflerinde dejeneratif değişiklikler ve nükleer kayıp tespit edildi. Kokleada gelişen bu dejeneratif değişiklikler cisplatin-gentamisin kombinasyonu verilen çalışma grubunda yalnız başına cisplatin verilen çalışma grubuna göre daha şiddetli olduğu görüldü. Aralarındaki fark istatistiksel olarak Wilcoxon Signed-Rank testi ile anlamlı bulundu (p<0.001). Böylece, cisplatin-gentamisin kombinasyonunun tek başına cisplatin kullanımına göre daha fazla ototoksik olduğu kanısına varıldı.
