ABSTRACT

Objective: To determine the efficacy of the use of peak nasal inspiratory flow to evaluate its correlation with the degree of nasal obstruction as a predictive tool for response to conservative or surgical treatment in patients whit allergic rhinitis.
Material and Method: A correlation analytical study was carried out by means of simple non-probabilistic sampling of consecutive cases, prospective and analytical of the patients of the otolaryngology outpatient clinic, with allergic rhinitis that referred nasal obstruction among their symptoms from August to October 2017. Initial assessment and follow-up were performed at 30, 60 and 90 days with the NOSE scale, inferior turbinates were classified by anterior rhinoscopy and the peak nasal inspiratory flow was measured before and after the application of phenylephrine.
Results: Fourty-six patients with allergic rhinitis with nasal obstruction, 19 men (41.3%), with a mean age of 42.7 ± 13.1 years, were included in the study. Between the NOSE scale and peak nasal inspiratory flow it was found that the initial correlation prior to phenylephrine was -0.015, after phenylephrine -0.243, at 30 days 0.093 y -0.209, at 60 days -0.195 y -0.244, respectively, so, no correlation was found.
Conclusions: Peak nasal inspiratory flow is not a useful tool for choosing the type of treatment for nasal obstruction in patients with allergic rhinitis, since the correlation with the NOSE scale was less than 0.45.
