It is widely known that patients with chronic rhinosinusitis (CRS) commonly suffer from sleep disruption. Many of these patients have the associated diagnosis of obstructive sleep apnea (OSA). However, little is known about the risk factors for developing OSA in the CRS population. This study aims to identify these risk factors.
We performed a cohort study of 1004 patients with confirmed diagnostic criteria for CRS. Patient charts were reviewed to identify those with sleep study confirmed OSA. Patient charts were further reviewed for demographic information (age, ethnicity, race, sex, BMI) and medical history including: duration of CRS, presence of nasal polyps, number of endoscopic sinus surgeries, asthma, asthma hospitalizations, asthma ED visits, AERD, allergic rhinitis, eczema, food allergy, GERD, GERD treatment, anosmia and Lund-Mackay score (LMS).
970 patients were included. Logistic or linear regression analyses were performed to correct for BMI. Blacks were at higher risk for OSA (20.7% vs. 10.5% in Latinos and 8% in whites). Higher age was associated with higher risk for OSA. Male gender was a risk factor for OSA (14.2% in Male vs 9.4% Female). OSA was more common in CRSsNP patients. In CRSsNP cases, OSA was associated with GERD and duration of CRS. 25% of male CRSsNP patients above 40 had OSA; this prevalence increased to 40% in male black CRSsNP patients above 40yrs.
Patients with CRS should be screened for OSA. Especially male, black CRSsNP cases who are older than 40 years old.
