A two-year-old with earache, malaise, fever, and hearing loss—what is the most likely diagnosis?

• A. Labyrinthitis
• B. Otitis externa
• C. Mastoiditis
• D. Otitis media

Answer: (D)

Acute otitis media is the most likely diagnosis because in young children, ear pain with fever and malaise almost always points to a middle-ear infection that often follows a viral upper respiratory illness. The middle ear fills with inflammatory exudate, causing the tympanic membrane to bulge and its movement to be reduced. This disruption of the normal sound-conduction process leads to hearing loss, which is commonly described by parents as the child seeming less responsive to sounds or unsettled in the presence of noise. Think about how different ear problems present. Infection of the ear canal (otitis externa) causes ear pain, especially with movement of the outer ear, and often has canal swelling or discharge rather than a prominent fever and systemic malaise. Mastoiditis is a more serious progression with swelling and tenderness behind the ear and often marked fever and toxicity. Labyrinthitis would bring vertigo and balance disturbances rather than just ear pain and hearing loss. The combination of earache, fever, malaise, and hearing loss in a toddler fits middle-ear infection driving conductive hearing loss due to fluid and membrane changes.
