Embodiment 1

[0038] Example 1. Verification of the preventive or therapeutic effect of platelet-rich plasma on deafness or tinnitus

[0039] To examine whether platelet-rich plasma exhibits a preventive or therapeutic effect on deafness or tinnitus, its clinical efficacy was evaluated.

[0040] 1. Select subjects and conduct pure tone hearing test

[0041] Hearing tests of the subjects were performed by pure tone audiometry. An endoscope is introduced into the subject's external auditory canal to observe the subject's eardrum. Pure-tone audiometry was performed on subjects with sensorineural deafness but without external and middle ear damage.

[0042] The pure tone audiometry is a method of measuring the pure tone hearing threshold at each tone frequency, and the hearing threshold is measured at frequencies of 0.5KHz, 1KHz, 2KHz, 3kHz, 4kHz, 6kHz and 8kHz.

[0043] In pure tone audiometry, the average intensity of audible tones in normal healthy young adults was determined to be 0 deci...
