摘要
Chronic rhinosinusitis is defined by symptoms of nasal discharge or obstruction for at least 12 weeks, accompanied either by facial pain, facial pressure, or by hyposmia [1–3]. Diagnostic confirmation is provided by documentation of nasal polyps, mucopurulent discharge, edema, or mucosal changes within the osteomeatal complex or sinuses by endoscopy or computed tomography imaging.
