Acute sinusitis is characterized by its duration, which typically lasts less than four weeks. This form of sinusitis often follows a cold or respiratory infection and is marked by sudden onset symptoms such as nasal congestion, facial pain, and thick nasal discharge. The definition of acute sinusitis emphasizes the temporary nature of the condition, distinguishing it from chronic sinusitis, which persists for 12 weeks or longer, often exhibiting a more gradual onset and ongoing symptoms that may fluctuate over time. This key distinction in duration is essential for understanding the different management and treatment approaches for these two conditions.
