Fistula test

The fistula test is used when examining a patient with recurrent vertigo.

A finger is abruptly applied to the external meatus which causes a pulse of air-transmitted pressure. If nystagmus is induced in association with vertigo, it indicates bony destruction within the inner ear e.g. cholesteatoma.
