The author presents an account on ambulatory screening of tumours of the pontocerebellar angle. The procedure was adopted from the literature and tested in 21 patients with a tumour of the pontocerebellar angle who were operated at the authors’ department. The procedure makes comprehensive evaluation of the patient’s condition possible and thus also selection for NMR examination already in ambulatory ENT practice. The screening does not require expensive equip- ment. This screening is a useful supplement in clinical diagnostics.
