Rhinomanometry is a form of manometry used in evaluation of the nasal cavity. Rhinomanometry is a standard diagnostic tool aiming to objectively evaluate the respiratory function of the nose. It measures pressure and flow during normal inspiration and expiration through the nose. Increased pressure during respiration is a result of increased resistance to airflow through nasal passages (nasal blockage), while increased flow, which means the speed of airstream, is related to better patency. Nasal obstruction leads to increased values of nasal resistance. Rhinomanometry may be used to measure only one nostril at a time (anterior rhinomanometry) or both nostrils simultaneously (posterior rhinomanometry).

• Rhinomanometry is a form of manometry used in evaluation of
the nasal cavity. Rhinomanometry is a standard diagnostic tool aiming
to objectively evaluate the respiratory function of the nose. It
measures pressure and flow during normal inspiration and expiration
through the nose. Increased pressure during respiration is a result of
increased resistance to airflow through nasal passages (nasal
blockage), while increased flow, which means the speed of airstream,
is related to better patency. Nasal obstruction leads to increased
values of nasal resistance. Rhinomanometry may be used to measure
