Chronic rhinosinusitis (CRS) is a common inflammatory condition of the nasal and paranasal mucosa, characterized by persistent or recurrent symptoms lasting more than 12 weeks. Among its cardinal manifestations, facial pain or pressure, nasal obstruction, and nasal discharge are considered essential for clinical diagnosis. This study explores the diagnostic relevance of these symptoms, analyzing their frequency, severity, and correlation with radiological and endoscopic findings. The presence and intensity of each symptom vary across individuals, but a combination of nasal obstruction and purulent discharge strongly correlates with objective signs of sinus inflammation. Recognizing the diagnostic patterns of these symptoms is crucial for early detection, appropriate treatment, and prevention of complications in CRS patients.
