Pre-operative ENG was carried out in 23 patients with cholesteatoma. The relationship between ENG findings and dizziness or middle ear disease was investigated. Those with nystagmus directed to the affected ear complained of significantly more dizziness than did the others. Cholesteatoma and/or granulation around the stapes was seen significantly more frequently in the former than in the latter patients. Patients with canal paresis (CP) in the affected ear had dizziness and pathologic findings around the stapes significantly more often than did CP-negative patients. These results suggest that pre-operative ENG can provide some information about lesions in the middle ear and inflammation of the inner ear.
