Intranasal aerodynamic aspects in patients with nasal septal perforations.

In an attempt to determine the influence of septal perforations on nasal airflow, nasal resistances were measured with active posterior rhinomanometry and compared before and after closure of asymptomatic septal perforations in five patients. No significant differences were found in the nasal resistances before and after closure of perforations either on inspiration or expiration. All patients were also unaware of any perceptive changes in nasal patencies after closure of the perforations.
