title: The choana and nasal obstruction.
abstract: A subject with a septal perforation was studied rhinometrically to confirm that the congested choana did not limit airflow when the anterior nose was decongested. It did not. This suggests that in an undefined proportion of patients with swollen diseased mucosa, surgery to the anterior nose may be sufficient to relieve nasal obstruction.
