Retroauricular Injection of Methylprednisolone for the Treatment of High Frequency Decreased Sudden Deafness
Glucocorticoids can reduce the damage caused by immune reaction, improve the activity of Na+-K+-ATPase, thereby improve the function of inner ear veins, reduce cell edema, improve vasospasm, and thus reduce inflammatory damage and inflammatory damage leading to hair cells. damage. This article investigates the efficacy of auricular injection of methylprednisolone as a remedy in the treatment of sudden and medium-frequency hearing loss. Forty-five patients with moderate to high frequency hearing loss type sudden deafness who were ineffective after 2 courses (14 days) were screened, including 25 cases of follow-up routine treatment and 20 cases of post-auricular injection of methylprednisolone. Difference in efficacy. The results showed that the hearing of each frequency increased, and the difference in hearing improvement between 2000 and 8000 Hz was statistically significant. The effective rates of the conventional treatment group and the post-injection group were 42% and 81%, respectively. It indicates that the injection of methylprednisolone can be used as a remedy for the treatment of sudden deafness, improve the cure rate of sudden deafness, and easy to inject after the ear, which can improve the treatment efficiency of patients with sudden deafness in middle and high frequency hearing loss.
