A study about correlation between frontal recess cells and degree of opacification of frontal sinus in chronic rhinosinusitis

Abstract

The aim of this study was to evaluate the effect of frontal cells on the frontal recess involvement and the degree of opacification on CT scan in patients with frontal rhinosinusitis.

Methods: In this cross-sectional study, patients older than 18 years with inflammatory symptoms of rhinosinusitis lasting for at least 3 months were included in the study and a control group was included as well. Demographic findings, clinical signs and symptoms and patients CT scans findings were recorded and the correlation between the number of frontal cells and the degree of opacification according to the Lund Mackay score (LM) was assessed.

Findings: In this study, 26 people were present in the control group and 25 people in the experimental group. The mean age of the patients was 38.18 ± 15.33 years. Purulent rhinorrhea and nasal congestion were much more common in the experimental group compared to the control group (P.Value <0.05). The degree of opacification in the experimental group was much higher than the control group (P. Value <0.05). Except for the type 2 frontoethmoidal cells which were more common in the experimental group, there was no significant difference in the type and number of frontal cells between the groups (P.Value> 0.05). Also, there was no relationship between the degree of opacification and the number of frontal cells (P.Value> 0.05). There was a significant association between the number of frontal cells and the presence of congestion and decreased smell sensation, while the degree of opacification was associated with increased rhinorrhea (P.value <0.05).
