Effectiveness of intratympanic injection of dexamethasone in treatment of acute sensorineural hearing loss

Abstract

Acute sensorineural hearing loss is a common pathology in the human population due to impaired sound perception. Along with the widespread systemic use of glucocorticosteroids in recent years, there has been a keen interest in their local delivery via intratympanic injections or through a previously installed shunt in the eardrum. The experience of treating 40 patients with ASNHL is presented. Patients of the 1st group received a systemic course of dexamethasone, and patients of the 2nd group received dexamethasone through the superimposed perforation in the eardrum using a current frequency of 4 MHz. Audiological examination was performed before treatment, 1, 2 weeks, 1 and 6 months after treatment. Local treatment of ASNHL is as effective as their systemic use and can be used as the main one. The method of radiofrequency myringotomy is safe and convenient in treatment by intra-implantation of glucocorticosteroids into the tympanic cavity.
