Manometric rhinometry.
A new method of measuring nasal volume is described. It works by extracting air from a closed cavity and measuring the resultant pressure change. To validate this method in the nose, 17 healthy volunteers were examined before and after application of xylometazoline. The apparent volume before decongestion was a mean of 204 ml. After decongestion the average volume was 228 ml. The difference is highly significant (P < 0.01). We conclude that manometric rhinometry is a valid method of investigating the nose and sinuses.
