Effect of intratympanic dexamethasone injection in sudden idiopathic sensorineural hearing loss

Abstract

<p class="abstract"><strong>Background:</strong> The aim of this study is to assess the effect of intratympanic dexamethasone injection (ITDI) in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).</p><p><strong>Methods:</strong> A prospective study was conducted on 40 patients refractory to intravenous steroid therapy between May 2012 to March 2014. Intratympanic dexamethasone injection was given every week for 3 consecutive weeks. Hearing was assessed by performing pure tone audiogram before every ITDI and also 1 week after the completion of treatment.</p><p><strong>Results: </strong>Hearing improvement was seen in 27 out of the 40 cases (68%).<strong></strong></p><p class="abstract"><strong>Conclusions:</strong> Intratympanic dexamethasone significantly improves the prognosis of ISSNHL and is a safe, inexpensive and effective treatment in ISSNHL.</p>
