Differential Diagnosis for Ear Drum Red with Some Yellow

  • Single most likely diagnosis
    • Otitis media: This is the most likely diagnosis due to the presence of a red ear drum with some yellow, which could indicate an infection with possible pus or fluid accumulation behind the ear drum.
  • Other Likely diagnoses
    • Eustachian tube dysfunction: This condition can cause the ear drum to appear red and possibly lead to a middle ear infection, which might present with a yellowish tint due to fluid.
    • Ear wax impaction: Although less common, a severe ear wax impaction could cause inflammation and potentially lead to a red ear drum with a yellowish appearance if the wax is infected.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Mastoiditis: This is a serious infection of the mastoid bone in the skull, located behind the ear. It can arise from untreated or inadequately treated otitis media and is characterized by redness, swelling, and tenderness behind the ear, which might initially present with a red ear drum and possible yellowish discharge.
    • Petrositis: Inflammation of the petrous portion of the temporal bone, which can be a complication of otitis media. It's crucial to identify and treat promptly to avoid serious complications.
  • Rare diagnoses
    • Relapsing polychondritis: A rare autoimmune disorder that can cause inflammation of the cartilage in the ear, leading to redness and possible changes in the appearance of the ear drum.
    • Cholesteatoma: An abnormal skin growth in the middle ear behind the ear drum, which can be dangerous if it grows and causes damage. It might present with a range of symptoms including a red ear drum and possible discharge.
