Neuro-otological findings in patients with small acoustic neuromas

The method of choice for the diagnosis of even the smallest acoustic neuromas is CT gas cisternography. Lumbar puncture and gas insufflation, however, is an intervention demanding strict indication. Neuro-otological examinations should lead to this indication. The aim of this paper is to demonstrate neuro-otological findings on 19 patients presenting small acoustic neuromas. These neuro-otological findings are not necessarily comparable to earlier reports in the literature dealing with mainly larger tumours at a time when early diagnosis was not so advanced.
