This document outlines acute suppurative otitis media (ASOM), an infection of the middle ear. It discusses the definition, causes, risk factors, symptoms, diagnosis, and treatment options. ASOM is caused by bacterial infection of the middle ear mucosa. Common pathogens include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Risk factors include age, socioeconomic status, climate, upper respiratory infections, allergies, and anatomical abnormalities. Symptoms are fever, ear pain, deafness, vertigo, and ear discharge. Treatment involves medical management with antibiotics or surgical drainage if medical treatment fails.
