Introduction
Optical rhinometry is a newly standardized technique for assessing nasal obstruction in nasal allergen provocation testing. It is one of the few techniques that accurately determine the beginning of an allergic reaction as it measures optical density, which is consistent with the degree of response.
Aim: To evaluate the usefulness of optical rhinometry in nasal allergen provocation testing.
Material and methods
The study population was a group of 45 subjects (25 diagnosed with an allergy to common environmental allergens and 20 controls). Nasal allergen provocation testing was conducted with the use of Dermatophagoides pteronyssinus and Dermatophagoides farina (5,000 SBU/ml).
Results
The onset of the nasal mucosa allergen response in the form of nasal obstruction was observed at 10.40 min. The subsequent reaction developed rapidly, with only 53 s from the initial stage of nasal obstruction to complete obstruction (optical density 0.4552).
Conclusions
Due to its informative potential, optical rhinometry is a valuable tool in assessing the nasal mucosal response to topical allergen application.
