What is a common objective sign of otitis media?

Drainage from the ear is a common objective sign of otitis media, which is an infection or inflammation of the middle ear. When the middle ear becomes infected, fluid and pus can accumulate behind the eardrum. This accumulation can lead to the eardrum rupturing, resulting in drainage from the ear canal. This drainage is an observable sign that healthcare professionals look for during an examination and is indicative of a possible ear infection.

In contrast, while rash on the skin, loss of balance, and pain in the jaw can be symptoms associated with various conditions, they are not specific objective signs of otitis media. A rash may point to other infectious or allergic issues, loss of balance could indicate inner ear problems or neurological issues, and jaw pain might suggest dental issues or temporomandibular joint disorders. Therefore, drainage from the ear is specifically linked to the presence of otitis media and serves as a key indicator for diagnosis.
