Background:

It is described that 2% of patients with asymmetric hearing loss have retrocochlear lesions. The scrutiny behavior has been based on audiometry. There are several definitions of audiometric asymmetry described in the literature, but without reaching a consensus. Although the gold standard for the diagnosis of vestibular schwannoma is gadolinium magnetic resonance imaging, the clinical suspicion is based on audiometric asymmetry.

Objective:

we review the results published in this regard in the literature and comment on our own experience.

Reflection:

we want to emphasize the importance of studying asymmetric hearing loss patients in order to rule out retrocochlear etiology.

Conclusions:

although there is no clear consensus on the definition of asymmetric hearing loss, the clinical suspicion of a vestibular schwannoma is based on the audiometry.
