Objective:
To analyze the efficacy of Methylprednisolone hemisuccinate intratympanic injection for refractory noise induced deafness.
Methods:
One hundred and twenty cases (215 ears) of noise induced deafness were treated with either hormone group (107 ears) or with non hormone group (108 ears). Following prior interventions, 145 ears went on to receive intratympanic Methylprednisolone hemisuccinate injection twice a week.
Results:
After Intratympanic therapy, the total effective rate was 46.2%. 32 of 71 ears (45.1%) demonstrated hearing improvement in hormone group and 35 of 74 ears (47.3%) in non hormone group. The difference was statistically insignificant (P = 0.788).
Conclusion:
Intratympanic therapy appears to provide additional treatment benefits for patients with refractory noise induced deafness who have been treated with prior interventions. The outcome is not affected by pretreatment with hormone.
