Arising within the respiratory system across pediatric and adult populations, it frequently develops as a secondary complication following viral upper respiratory tract infections or allergic mucosal inflammation that impairs mucociliary clearance and obstructs the ostiomeatal complex Pathophysiologically, the bacterial proliferation and subsequent neutrophil recruitment lead to purulent exudate accumulation and mucosal edema
