Surgical indications or inclusion/exclusion criteria of explorative tympanotomy on sudden sensorineural hearing

We read with great interest the work described in the article entitled, "The role of explorative tympanotomy (EXT) in patients with sudden sensorineural hearing loss with and without perilymphatic fistula," by Prenzler et al. [1]. Sudden sensorineural hearing loss (SSNHL) is a medical emergency frequently seen in patients presenting in the otology clinic. With increasing productivity at work, increased psychological pressure of modern life, and frequent use of headphones, SSNHL has become increasingly common in recent years.
