Fundamental and Clinical Studies of the Rhino-Maxillo Aerodynamic-Grams Used to Measure the Patency of the Maxillary Ostium

Part 1: Method of Examination

Abstract

Determining the patency of the maxillary ostium is very important in the diagnosis of chronic sinusitis.
The usefulness of the Rhino-Maxillo Aerodynamic-Gram (R. M. A. G.) in examining the patency of the maxillary ostium was evaluated in patients with sinusitis, the R. M. A. G. finding were correlated with the results of other examinations.
1) The R. M. A. G. findings reproduce the patency of the maxillary ostium more clearly than the endoscopic, histological or bacteriological findings.
2) No relationship was recognized between the R.M.A.G. findings and the subjective symptoms.
3) A certain correlation was found between the R. M. A. G. findings and the simple radiograms of the ethmoid sinus.
4) There was a positive correlation between R. M. A. G. and X-M. F. T. findings.
It is concluded that R.M.A.G. is a simple method of measurement, high in reproducibility, and is useful in the quantitative analysis of patency of the maxillary ostium.
