[A new method for diagnostic-therapeutic evaluation of rhinomanometry results]

We have developed a new method for the clinical evaluation of nasal permeability by comparing flow (Vt) and subjectively estimated patency (D). In a coordinate system Vt is marked on the y-axis and D is recorded on the x-axis. The y-axis is separated into an operative and a non-operative part. The limit of Vt is 700 cm3/s. Four quadrants are produced, in which quadrant I is a conformity between the non-operative part of the flow and the value estimated by the patient (showing that no operative intervention is indicated). Conformity between the operative part and estimated value in quadrant III means that an operation is indicated. Discrepancies exist in quadrants II and IV and designate conservative therapy. Since clear directions for treatment are possible from each quadrant, the principle is easily programmable for use in a microprocessor, which is small and portable.
