Pathophysiologically, it typically develops as a secondary complication following viral upper respiratory tract infections or odontogenic sources, where ostial obstruction and impaired mucociliary clearance foster bacterial proliferation, predominantly by *Streptococcus pneumoniae*, *Haemophilus influenzae*, or *Moraxella catarrhalis*
