Acoustic rhinometry allows measuring the degree of permeability of the nasal passages for air, the dimensions of the first five centimeters of the nasal passages (before and after vasoconstrictor or nasal dilator as RespiFacile).

It allows to encrypt and locate a endonasal obstacle, as for example an enlarged turbinates, on a curve with three accidents in the form of negative vibes obstacle – a first wave is fixed and corresponds to the end of the nasal tube . It is about 0.5 cm beyond the nasal orifice – the second wave is about 2 cm from the nostril hole and corresponds to the region of the valve including the head of the inferior turbinate – the third wave is about 6 cm from the nostril hole and corresponds to the tail of the inferior turbinate. In patients with turbinate hypertrophy, the surface of minimum area is located at the head of the inferior turbinate. The advantages of this technique are its speed, reproducibility, non-invasive nature and minimal cooperation required from the patient.

This review is fast and simple and practice before and after laser turbinectomy in the context of an enlarged turbinates causing a chronic stuffy nose.

The measurement of peak nasal inspiratory flow (DNIP) is particularly simple and inexpensive. It remains underutilized in comparison with its potential indications.

Rhinomanometry, often earlier than later, is difficult to confirm its real place in everyday clinical Rhinology. (in addition to the difficulties of implementation).
