Pathophysiologically, the condition commonly arises following a viral upper respiratory tract infection that causes eustachian tube dysfunction, enabling bacterial pathogens—predominantly *Streptococcus pneumoniae*, nontypeable *Haemophilus influenzae*, or *Moraxella catarrhalis*—to colonize the normally sterile middle ear It is clinically defined by middle ear effusion accompanied by acute otalgia, distinct bulging and erythema of the tympanic membrane, fever, and otorrhea if perforation occurs
