Answer

Acute sinusitis is a clinical diagnosis; thus, an understanding of its presentation is of paramount importance in differentiating this entity from allergic or vasomotor rhinitis and common upper respiratory infections. No specific clinical symptom or sign is sensitive or specific for acute sinusitis, so the overall clinical impression should be used to guide management. (See Clinical Presentation.)
