Audiometry
An audiometry evaluation is a painless, noninvasive hearing test that measures a person’s ability to hear different sounds, pitches, or frequencies. Patients with a tumor in or around the ear may undergo audiometry testing to determine whether a hearing loss has occurred or to monitor their hearing before and after surgery. It also evaluates whether hearing aids or surgery may improve hearing.
An Audiometry can diagnose the following conditions
- Acoustic neuroma: a benign slow-growing tumour that forms on the sheath of the eighth cranial nerve. This tumour can cause hearing loss, balance problems, and facial paralysis.
- Conductive hearing loss is caused by damage to the eardrum or ossicle bones.
- Sensorineural hearing loss is caused by damage to the vestibulocochlear nerve.
- Tinnitus: ringing or buzzing noise in the ear.
- Vertigo: a feeling of spinning, whirling or turning.
- Vestibulocochlear nerve: the eighth cranial nerve responsible for hearing and balance.
