Differential Diagnosis for Right Sided Ear Pain
Single Most Likely Diagnosis
- Otitis Externa: This is the most likely diagnosis given the patient's symptoms of ear pain, tenderness to palpation, and pain during the ear exam. Otitis externa, also known as swimmer's ear, is an inflammation of the outer ear and ear canal, often caused by bacterial or fungal infections.
Other Likely Diagnoses
- Otitis Media: This is an infection of the middle ear, which can cause ear pain, fever, and difficulty hearing. It's a common condition, especially in children, but can also occur in adults.
- Eustachian Tube Dysfunction: This condition occurs when the tube that connects the middle ear to the back of the throat becomes blocked, leading to ear pain, fullness, and hearing loss.
- Earwax Impaction: A buildup of earwax can cause ear pain, itching, and hearing loss, and can be tender to palpation.
Do Not Miss Diagnoses
- Mastoiditis: This is a serious infection of the mastoid bone, located behind the ear, which can cause ear pain, fever, and headache. If left untreated, it can lead to serious complications, such as brain abscess or meningitis.
- Petrous Apicitis: This is a rare but serious infection of the petrous portion of the temporal bone, which can cause ear pain, fever, and cranial nerve palsies.
- Ramsay Hunt Syndrome: This is a viral infection caused by the varicella-zoster virus, which can cause ear pain, facial weakness, and vesicles in the ear.
Rare Diagnoses
- Relapsing Polychondritis: This is a rare autoimmune disorder that can cause inflammation and destruction of cartilage in the ear, leading to ear pain and deformity.
- Ear Cancer: Although rare, cancer of the ear can cause ear pain, hearing loss, and other symptoms, and should be considered in the differential diagnosis, especially in older adults or those with a history of radiation exposure.
Treatment and Relief
Treatment for the single most likely diagnosis, Otitis Externa, typically involves:
- Topical antibiotics, such as neomycin or polymyxin B
- Pain relief, such as acetaminophen or ibuprofen
- Keeping the ear dry and avoiding further irritation
- In some cases, oral antibiotics may be prescribed if the infection is severe or spreading.
It's essential to note that the treatment should be guided by the specific diagnosis and the patient's overall condition. A thorough examination and diagnostic workup may be necessary to determine the underlying cause of the ear pain and to develop an effective treatment plan.
