Özet

Objective: This study aimed to test at an experimental level the contributions of traditional treatments with Platelet Rich Plasma (PRP) to the recovery of hearing in hearing loss due to acoustic trauma. Methods: Thirty healthy adult rats were used in the study. Otoacoustic Emission (OAE) measurements were performed before the study. All rats with OAE measurements were exposed to 95 dB pure tone sound at a frequency of 4 kHz for 60-minutes. OAEs of the experimental animals were measured again at the 24th hour and it was determined that acoustic trauma had occurred. The rats were divided into 3 groups of 10, the first group was the control group, the 2nd group was determined as the group in which approximately 0.5 mL of intratympanic PRP was injected for 5 doses with 2 days intervals, and the 3rd group was determined as the group in which approximately 0.5 mL of intratympanic steroid was injected with 2 days intervals. OAE measurements made after 7 and 21 days were evaluated, and the treatments given were compared to the group without treatment. Results: The results obtained from day-by-day and frequency-by-frequency measurements of DPOAE were statistically compared to check whether significant results were obtained. It was determined that better results were obtained in rats with acoustic trauma treated with PRP and prednol compared with acoustic trauma who received no treatment, and close treatment efficacy results were found between PRP and prednol groups. Conclusion: When DPOAE measurements of these three groups at 4 kHz frequency on various days were compared with Group 1, a significant statistical difference was observed in Groups 2 and 3, but no significant difference was found between Groups 2 and 3. It was concluded that PRP is as effective as steroids in the improvement of hearing.
