Aim To assess the cochlear damage caused by cisplatin in the rat cochlea based on decreased signal to noise ratio (SNR) values on otoacoustic emission (OAE) examination and increased expression of signal transducer and activator of transcription 1 (STAT 1) and vascular endothelial growth factor (VEGF) on immunohi-stochemical examination. Methods Twenty-four Rattus norvegicus were divided into 4 groups and injected with 8 mg/kgBW of cisplatin intraperito-neally except for control group. The SNR on OAE examination were checked before the treatment and on day 3, 4, and 7 after the treatment. The cochleas were stained immunohistochemically, followed by assessment of the cochlear organ of Corti damage based on STAT 1 and VEGF expression. Results A decrease in the mean of SNR value was found in accor-dance with the length of cisplatin exposure. The STAT 1 and VEGF expression increased with duration of cisplatin exposure. A correlation was found between SNR values, STAT 1, and also VEGF expression (p<0.05). Conclusion An increase of STAT 1 and VEGF expression influ-ences cochlear damage due to cisplatin administration. There was a correlation between STAT 1 and VEGF expression with SNR values in the cochlear organ of Corti of Rattus norvegicus exposed to cisplatin. © 2023, Medical Association of Zenica-Doboj Canton.
