Article Title	The symptom burden of autonomic dysfunction is positively associated with chronic rhinosinusitis status
Abstract	BACKGROUND: Dysregulation of the autonomic system can affect sinonasal physiological function and may exacerbate the symptom burden associated with rhinosinusitis. However, the association between autonomic dysfunction and chronic rhinosinusitis (CRS) has seldom been studied. Here, we investigated the relationship between autonomic dysfunction and CRS. METHODS: Patients with CRS who failed medical treatment were prospectively enrolled. All patients underwent pre-operative examinations and completed questionnaires, including the reflux symptom index (RSI) and the Sino-nasal Outcome Test-22 (SNOT-22). Autonomic dysfunction was scored using the 31-item Composite Autonomic Symptom Score (COMPASS 31), a validated simple instrument used to evaluate dysautonomia. RESULTS: We prospectively enrolled a total of 89 CRS patients, including 37 with polyps (CRSwNP) and 52 without polyps (CRSsNP). The most common dysautonomic symptoms were dry eye, dry mouth, postural dizziness, and a sensation of excessive fullness after meals. Significant positive correlations were evident between COMPASS 31 and SNOT-22 scores in CRSwNP patients. CRS-associated symptoms, including cough, post-nasal drip, sleep, and psychological dysfunction, were correlated with the level of autonomic dysfunction. CONCLUSIONS: We found a positive correlation between the symptom burdens of autonomic dysfunction and CRSwNP. The relationship between autonomic dysfunction and CRS is highly complex; further work is needed.
