The use of SN-5 to differentiate chronic rhinosinusitis and chronic adenoiditis in children

Abstract

Background: Chronic adenoiditis (CA) and chronic rhinosinusitis (CRS) present with similar symptoms, but an accurate diagnosis is critical for optimal treatment. We aim to differentiate CRS and CA based on sinonasal symptoms using the Sinus and Nasal Quality of Life Survey (SN-5) in children.

Methods: This is a retrospective cohort study. Children (age 12 and younger) presenting with chronic sinonasal symptoms were divided into 2 groups based on CT scan sinus findings: CA group included patients with CT Lund-Mackay (LM) score <5 and CRS group included patients with CT LM score of 5 and more. SN-5 scores for each group were then compared, and both groups were compared to a control group. Other demographic data were also collected and analyzed.

Results: There were 27 patients in the CA group, 42 patients in CRS group and 38 patients in the control group. Mean SN-5 scores were 2.03±0.71 for the control group, 3.49±1.00 for the CA group, and 4.53±0.77 for the CRS group (p < 0.0001); Statistical significance persisted when CA and CRS were compared in subset analysis (p < 0.0001). CT LM score was 2.70±2.07 for the CA group and 9.94±3.46 for the CRS group (p < 0.0001). Rates of asthma, allergic rhinitis, and smoke exposure differed between the three groups (p < 0.01), but they were not statistically different when CA and CRS were compared in subset analysis.

Conclusion: Children with CRS have higher SN-5 score than children with CA. SN-5 score can be used to help otolaryngologists differentiate between these two clinical entities.
