Nationwide Survey of Intratympanic Steroids for the Management of Sudden Sensorineural Hearing Loss.

BACKGROUND

The currently accepted treatment for idiopathic sudden sensorineural hearing loss (ISSHL) is systemic steroids as first-line and intratympanic steroids as salvage therapy. Intratympanic (IT) treatment is applied worldwide in many different ways with no universally accepted protocol.

OBJECTIVES

To present the current disparity in ISSHL management and to discuss the necessity for establishing a common national protocol.

METHODS

In 2014 we conducted a national survey by sending questionnaires on ISSHL management to otologists in every otolaryngology department in the country.

RESULTS

The majority of otolaryngology departments (56%) admit patients with sudden sensorineural hearing. Almost two-thirds (61%) of departments recommend supplementary initial treatment in addition to systemic steroids. None of the medical centers offer intratympanic steroid treatment as primary therapy, but 94% offer this treatment as a salvage therapy. Fewer than half the medical centers (44%) consider the maximal period for intratympanic therapy to be 4 weeks since hearing loss appears. Almost half (48%) the departments use intratympanic steroids once every 5-7 days, usually in an ambulatory setting. Almost half (44%) the medical centers tend to use not more than four courses of IT steroids. In 44% of departments an audiogram is performed at the beginning and at the end of the intratympanic course.

CONCLUSIONS

Our results demonstrate a variability among Israeli medical centers in many aspects of intratympanic treatment. We believe this reinforces the need for a comparative international study in order to establish a standard protocol.
