This study confirms the inter-rater and test-retest reliabilities of minimum cross-sectional area measurements of the nasal airway using acoustic rhinometry.
Methods – Two separate examiners measured minimum cross-sectional area with acoustic rhinometry on 25 normal volunteers on three consecutive days. Intraclass correlation coefficients were calculated.
Results – The overall mean minimum cross-sectional area was 0.61
