title: Nasal mucosal anaesthesia and airflow resistance.
abstract: The effect of topical lidocaine solution on nasal airflow resistance was examined in five adult subjects with normal noses, seated and recumbent. The increasing use of upper airway anaesthesia in the investigation of upper airway function and the lack of published information concerning its effect on nasal airflow resistance led to this investigation. Nasal airflow resistance did not significantly change during 30 minutes observation following topical application of 4% lidocaine solution.
