| Popis: | To investigate whether there is a correlation between active anterior rhinomanometry (RMM) and optical rhinometry (ORM) data in the detection of changes in nasal congestion.In 70 subjects both ORM and RMM were performed. Changes in nasal congestion were induced by nasal provocation with histamine, allergens, solvent, and xylometazoline hydrochloride, 0.1%. Using visual analog scales, subjects rated the degree of nasal congestion and how comfortable each of the 2 measures was. In total, 136 measurements were evaluated.Seventy subjects were included in the study. All had a normal otorhinolaryngologic status with no acute or chronic infections.Nasal provocation tests with allergens, histamine, control solution, or xylometazoline were performed.Congestion or decongestion of the nasal mucosa was measured via nasal resistance (RMM), changes in light absorption of the nasal tissue (ORM), and visual analog scale.When comparing the relative change in light extinction in ORM with nasal airflow in RMM, we found correlation coefficients up to r = -0.69. Results from RMM were correlated with the subjects' ratings of nasal congestion (r = -0.63). In comparison, the correlation coefficient between these ratings and ORM was r = 0.84. In addition, ORM was rated to be more comfortable than RMM.The subjects' ratings of nasal congestion correlated to a higher degree with the results from ORM than with those from RMM. In addition, ORM was rated as more comfortable than RMM. Overall, ORM appeared to be a valid technique for the assessment of changes in nasal congestion. |
