A computer analysis of typical CCG patterns in 1,021 neuro-otological patients.

A set of 1,021 patients who were investigated at our Department over the last few years was investigated in this study. Each patient underwent Cranio-Corpo-Graphy, and other related investigations. The patients' CCG's were quantified using a specially developed computer scanning method, and a computerized spreadsheet databank was thus created. Also included in the study were their clinical profiles, as charted using the NODEC III questionnaire. The isolation and comparison of various data subsets enables us to draw broad correlations between clinical and CCG findings, and permits us to establish 'normal values' for various parameters. It is seen that cranio-corpography is a reliable screening method for the topodiagnosis of vertigo.
