Improving the rhinomanometry technique using benzoin tincture

In order to achieve a faster and more reliable anterior rhinomanometric evaluation, nasal skin was prepared using benzoin tincture solution, which provides simpler and better adhesion of the foam tape to the nasal skin.

Two consecutive anterior rhinomanometry measurements were made, one with and one without benzoin tincture application.

The average time taken to perform classic foam tape anterior rhinomanometry without benzoin tincture application was 281.32 seconds, and the average coefficients of variation for the right and left passages were 7.48 and 7.59 per cent, respectively. When benzoin tincture was used, the average time taken for completion of the tests was 121.24 seconds, and the average coefficients of variation for the right and left passages were 2.17 and 2.32 per cent.

The use of benzoin tincture to clean the nasal skin before placing foam tape shortens the procedure duration and significantly increases test reliability.
