Differential Diagnosis for Ear Pain

The following conditions can cause ear pain, categorized by their likelihood and potential impact:

  • Single Most Likely Diagnosis

    • Otitis media (middle ear infection): This is a common condition, especially in children, where bacteria or viruses infect the middle ear, causing pain, fever, and hearing loss.
    • Otitis externa (swimmer's ear): An infection of the outer ear canal, often caused by bacterial or fungal infections, leading to pain, redness, and swelling.

  • Other Likely Diagnoses

    • Eustachian tube dysfunction: A condition where the tube that regulates air pressure in the ear is blocked, leading to fullness, pain, and hearing difficulties.
    • Earwax impaction: A buildup of earwax that can cause pain, itching, and hearing loss if it blocks the ear canal.
    • Temporomandibular joint (TMJ) disorder: A condition affecting the joint that connects the jaw to the skull, which can cause ear pain, jaw pain, and clicking sounds when moving the jaw.
    • Dental problems: Issues like toothaches, abscesses, or gum disease can radiate pain to the ear.

  • Do Not Miss Diagnoses

    • Malignant otitis externa: A severe infection of the outer ear that can spread to the skull and brain, particularly in diabetic or immunocompromised patients.
    • Mastoiditis: An infection of the mastoid bone in the skull, which can lead to serious complications if not treated promptly.
    • Petrous apicitis: A rare but serious infection of the petrous part of the temporal bone, which can lead to neurological complications.
    • Lyme disease: A bacterial infection that can cause ear pain, among other symptoms, and requires prompt treatment to prevent long-term complications.

  • Rare Diagnoses

    • Ramsay Hunt syndrome: A viral infection that causes facial paralysis, ear pain, and sometimes hearing loss.
    • Otosclerosis: A condition where abnormal bone growth in the middle ear causes hearing loss and can lead to ear pain.
    • Cholesteatoma: A type of skin cyst in the middle ear that can cause ear pain, hearing loss, and balance problems.
    • Relapsing polychondritis: A rare autoimmune disorder that can cause inflammation and pain in the ears, among other symptoms.
