Round window sealing in treatment of SSNHL

Tympanotomy and sealing of the round window membrane is effective in the treatment of severe to profound SSNHL. There is evidence that early surgery performed within 5 days is more effective than later surgery. The existence of a detectable lesion of the round window membrane has no significant influence on recovery.

Vestibular function as prognostic factor in SSNHL

Korean authors measured vestibular function in 22 patients with unilateral sudden hearing loss; they did caloric test and cVEMP.

Caloric test was pathologic at 50% while cVEMP in 31.6%. This study showed that caloric test is reliable prognostic factor in patients with sudden sensorineural hearing loss (SSNHL).
