Differential Diagnosis for Right Upper Jaw Pain and Ear Fullness
- Single most likely diagnosis
- Temporomandibular Joint (TMJ) Disorder: This condition is characterized by pain in the jaw, face, and temples, which can radiate to the ear, causing fullness. The locking of the jaw and improvement over time also support this diagnosis.
- Other Likely diagnoses
- Dental Issues (e.g., tooth abscess, gum disease): Dental problems can cause referred pain to the ear and jaw, especially if the issue is in the upper teeth.
- Sinusitis: Inflammation of the sinuses can cause pain in the face, including the upper jaw, and may lead to ear fullness due to the Eustachian tube's connection to the nasal cavity.
- Earwax Impaction or Middle Ear Effusion: These conditions can cause ear fullness and may radiate pain to the jaw.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Trigeminal Neuralgia: A rare condition that causes intense pain in the face, which could be mistaken for jaw or ear pain. It's essential to consider this diagnosis due to its potential for severe pain and the need for specific treatment.
- Temporal Arteritis: An inflammatory condition that affects the blood vessels in the head, potentially causing jaw pain and ear symptoms. It's crucial to diagnose this condition promptly to prevent complications like vision loss.
- Malignancy (e.g., nasopharyngeal or parotid gland cancer): Although rare, cancers in this region can cause jaw pain, ear fullness, and other symptoms. Early detection is vital for effective treatment.
- Rare diagnoses
- Eagle Syndrome (Styloid Process Syndrome): A condition where an elongated styloid process causes pain in the face, ear, and jaw due to compression of nearby nerves.
- Glossopharyngeal Neuralgia: A rare condition characterized by intense pain in the throat, ear, and jaw, often triggered by swallowing.
- Otosclerosis: A condition that affects the middle ear, causing hearing loss and ear fullness, which may be accompanied by jaw pain in some cases.
