Ototoxicity is a common side effect of cisplatin chemotherapy. The aim of this study was to investigate the potential protective effect of chrysin against cisplatin-induced ototoxicity. Thirty-four adult female Wistar albino rats were separated into four groups: a cisplatin group (Group A), with cisplatin administered to ten rats once daily for three consecutive days at doses of 8 mg/kg body weight intraperitoneally (i.p.); a cisplatin plus chrysin group (Group B), with 8 mg/kg of cisplatin administered i.p. daily to ten rats for three consecutive days and 25 mg/kg of chrysin administered via oral gavage in a corn oil for 5 days: a chrysin group (Group C), with 25 mg/kgof chrysin administered via oral gavage in corn oil for 5 days to seven rats; and a control group (Group D), with 5 ml/kg of corn oil administered to seven rats via oral gavage for 5 days. Distortion product otoacoustic emission measurements were performed in the same ear of the rats under general anesthesia at baseline and on the first and fifth days after drug administration. No significant differences were noted between the measurements either in the chrysin group or in the control group. In the cisplatin group, there was a significant worsening of hearing compared to baseline and the measurements on the fifth day at all frequencies. In the statistical analysis, a statistically significant difference was observed at 5039, 6351, 8003, and 10078 Hz frequencies between the measurements on the first and fifth days. In the cisplatin plus chrysin group, there were statistically significant differences at frequencies of 2,003 and 5,039 Hz between the measurements at baseline and on the fifth day, at 3,175 and 5,039 Hz between the measurements on the first and fifth days, and at 8,003 and 100,078 Hz between the measurements at baseline and on the first day. According to these results, this study demonstrates that cisplatin-related ototoxicity can be prevented in rats by the administration of chrysin.
