Abstract:Objective To analyze the correlation between subjective evaluation, anatomical structure and nasal function measurements in chronic rhinosinusitis (CRS).Methods Forty-three CRS patients who visited our department between Sept 2019 and Oct 2020 were selected. Visual analogue scale (VAS) was used to evaluate their subjective symptoms of nasal congestion. Lund-Mackay score and Lund-Kennedy score system were used to evaluate the results of nasal sinus CT and nasal endoscopy. Acoustic rhinometry and rhinomanometer were used to evaluate their nasal ventilation. The correlation was analyzed by SPSS 19.0 software.Results Spearman correlation analysis showed that VAS score of nasal congestion in CRS patients was negatively correlated with minimum cross-sectional area 2 (MCA2), distance between nostril and minimum cross-sectional area 2 (MD2) and volume 2~5 (Vol2~5)(all P<0.05), and positively correlated with effective nasal resistance, Lund-Mackay score and Lund-Kennedy score (all P<0.05). Lund-Mackay score and Lund-Kennedy score were correlated with nasal acoustic reflex and nasal resistance (all P<0.05).Conclusion The combination of subjective evaluation, anatomical structure and nasal function measurements can comprehensively evaluate the severity of nasal congestion in patients with CRS, which is beneficial to the choice of treatment.
