I have gone through your query.
To reach the near diagnosis and exclusion of the other disease you need to go for the following otology tests:
1. Otoscopic finding of your ear.
both pure tone and impedance.
auditory evoked potentials.
4. Electrocochleography (ECOG).
5. Caloric testing/electronystagmography (ENG).
