A 5-year-old child presents to the clinic with a history of persistent ear discharge from the right ear for the past three weeks. The mother reports that the child had a severe ear infection about a month ago, treated with antibiotics, but the ear has been draining foul-smelling fluid since then. The child also complains of hearing loss in the affected ear. Otoscopic examination reveals perforation of the tympanic membrane with purulent discharge. A diagnosis of chronic suppurative otitis media (CSOM) is made, and the child is referred to an otolaryngologist for further evaluation and treatment.
