Otoneurological test results analyzed by means of a quantitative statistical method.

This report is a presentation of an approach to the prediction of cerebellar-pontine (C-P) angle tumors and four peripheral vestibular diseases from a mathematical statistical point of view. The present study was performed in an attempt to quantify multidimensional, quantitative data. The data analyzed were from a total of 143 patients with C-P angle tumors, Menière's disease, sudden deafness, vestibular neuronitis, and benign paroxysmal positional vertigo (BPPV). Tests were carried out mainly on otoneurological parameters. By means of discriminant analysis as employed in the quantification method, the patients were classified in the 4-dimensional space.
