    Abstract:
    OBJECTIVE: The Sino-Nasal Outcome Test (SNOT-20) is a rhinosinusitis quality of life instrument. Nonrhinologic illnesses like obstructive sleep apnea (OSA) may elevate SNOT-20 scores. We compared SNOT-20 outcomes in patients with chronic rhinosinusitis (CRS) to those in patients with OSA. METHODS: We analyzed prospectively collected data of patients with CRS and OSA. Pretreatment SNOT-20 and Lund-Kennedy endoscopy scores were obtained. Scores and patterns of SNOT-20 symptom distribution were compared. RESULTS: Fifty-seven patients had CRS and 65 patients had OSA. Both groups had elevated mean total SNOT-20 scores (28 ± 12.2 and 29 ± 10.7, respectively). Higher scores were noticed for OSA patients on the wellness section of the SNOT-20 and for CRS patients on the sinonasal section of the SNOT-20 (p < 0.001). CONCLUSIONS: CRS and OSA patients present with elevated total SNOT-20 scores but differ in their symptom distribution pattern. This study demonstrates that other disorders can elevate SNOT-20 scores and confirms the need for additional objective data to confirm CRS diagnosis.
