The aim of the study is to analyze a new method for the elaboration of endoscopic images of the nasal cavity called "videocapture" and to compare the data from this technique with the ones obtained with anterior active rhinomanometry. Videocapture is based on a software program able to process endoscopic images, to file them and to measure perimeter and area of the structures inside the images recorded. We enrolled 27 patients with inferior turbinate hypertrophy and we performed, before and after nasal decongestion test, anterior active rhinomanometry, acoustic rhinometry, videocapture to compare the results obtained with these different techniques. The results we got confirm in a statistically significant way, the reliability of videocapture and its easy way of application.
