Affecting the respiratory system in both pediatric and adult populations, the condition typically develops as a secondary complication following viral upper respiratory tract infections or allergic inflammation that impairs normal mucociliary clearance and obstructs the sinus ostia

Pathophysiologically, the entrapped bacteria proliferate within the poorly drained cavity, producing localized mucosal edema, purulent exudate, and hallmark symptoms such as unilateral or bilateral facial pain, cheek pressure, purulent nasal discharge, and nasal congestion persisting for up to four weeks
