Abstract

Introduction The measurement of extended high-frequency (EHF) audiometry has become more popular recently, mainly in connection with ototoxicity and noiseinduced hearing loss. New-onset tinnitus evaluation includes a standard hearing test that shows no pathology.

Objective The aim of the present study was to evaluate the possibility that acute tinnitus is essentially connected to sudden sensory neural hearing loss (SSNHL), by utilizing EHF audiometry in cases in which standard audiometry for frequencies between 250 Hz to 8 kHz is within normal limits.

Methods A retrospective study was conducted between January 2009 and May 2014 that included all patients presenting with acute tinnitus and normal standard audiometry. All patients underwent EHF audiometry and were treated accordingly.

Results Thirty-two patients with acute tinnitus and asymmetric sensorineural hearing loss on EHF audiometry were identified. The average deltas between the ears were between 9.2 and 33dB (worse in the affected ear).

Conclusion Extended high-frequency audiometry up to 20,000 Hz should be performed in all patients with acute tinnitus and standard audiometry within normal limits.
