Analysis of related factors of coins foreign bodies crossing the esophagus in 204 cases of children

Abstract

Objective:To evaluate the effect of systemic and intratympanic dexamethasone combination therapy on sudden deafness.Method:A total of 98 patients randomly divided into three groups: an intravenous corticosteroid (systemic corticosteroid monotherapy group); an intratympanic corticosteroid (IT monotherapy group); and a combination therapy group (IT plus systemic combination group). All patients were treated additionally with ginkgo-damole and mecobalamine and proton pomp inhibitor. An audiometry was performed before and after the therapies in all patients. Result:Of the total of 98 patients, 39 were receiving systemic corticosteroids, 28 received intratympanic(IT) corticosteroids, and 31 were receiving a combination of the two. A total of 65 patients (66.3%) responded positively to corticosteroid therapy. No significant differences were observed between the three groups (systemic group, IT and combination therapy group) in their overall response to treatment (P=0.61). Patients who suffered from concomitant tinnitus and dizziness responded less positively to the treatment (P=0.00）. Positive family history of SSNHL seems to be negative prognostic factors in the response to treatment (P=0.02).The response to treatment was not related to the initial severity of hearing loss (P=0.68) and pattern (P=0.28). Conclusion:This study did not find any difference in the rate of hearing improvement between systemic, intratympanic, and combined corticosteroid therapy for sudden hearing loss.
