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.

La conducta de escrutinio se ha basado en la audiometría. Existen varias definiciones de asimetría audiométrica descritas en la literatura, pero sin llegar a un consenso. Aunque la prueba de oro para el diagnóstico de schwannoma vestibular es la resonancia magnética con gadolíneo, la sospecha clínica se hace en base a la asimetría audiométrica. Objetivo: hacemos una revisión de los trabajos publicados al respecto en la literatura y comentamos nuestra experiencia. Reflexión: queremos enfatizar en la importancia de estudiar a los pacientes con hipoacusia asimétrica con el fin de descartar patología retrococlear. Conclusión: a pesar de que no existe un consenso claro en la definición de hipoacusia asimétrica, la sospecha clínica de un schwannoma vestibular se basa en la audiometría. Hipoacusia sensorineural asimétrica audiometría schwannoma vestibular diagnóstico audiología tallo cerebral tumor acúfeno oído audiology 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.
