Abstract

To evaluate optical rhinometry (ORM) as an objective evaluation of nasal patency using nasal provocation testing with Dermatophagoides farinae (Df) as compared with acoustic rhinometry. Prospective pilot. Academic rhinologic practice. Five adult healthy controls and five adult subjects with allergic rhinitis (AR) underwent nasal provocation testing with increasing concentrations of Df while undergoing ORM. The minimum concentration of Df causing a positive reading was recorded. Nasal cross-sectional area was measured before and after testing using acoustic rhinometry. Nasal patency was assessed subjectively after each challenge with the visual analogue scale. The median amount of Df causing a positive response on ORM was less in AR patients as compared to healthy controls, at 5000 AU/mL and greater than 10,000 AU/mL, respectively. There was a statistically significant correlation between the change in optical density in ORM and subjective nasal congestion after increasing Df challenges (r = 0.63; P = 0.0007). Similarly, there was a statistically significant correlation between change in optical density by ORM and both minimum cross-sectional areas as measured by acoustic rhinometry (r = -0.60, P = 0.03; and r = -0.64, P = 0.02,...Continue Reading
