Differential Diagnosis for Ear Fullness
- Single most likely diagnosis
- Eustachian tube dysfunction: This condition is the most common cause of ear fullness, as it leads to a failure of the middle ear to ventilate properly, resulting in a feeling of fullness or pressure.
- Other Likely diagnoses
- Middle ear effusion: Fluid accumulation in the middle ear can cause ear fullness, often accompanied by hearing loss or a sensation of the ear being plugged.
- Earwax impaction: A buildup of earwax can cause a feeling of fullness in the ear, as well as hearing loss or discomfort.
- Sinusitis: Inflammation of the sinuses can lead to Eustachian tube dysfunction, resulting in ear fullness.
- Allergic rhinitis: Similar to sinusitis, allergic reactions can cause Eustachian tube dysfunction, leading to ear fullness.
- Do Not Miss diagnoses
- Acoustic neuroma: A rare, benign tumor on the nerve connecting the inner ear to the brain, which can cause ear fullness, hearing loss, and balance problems. Although rare, it's critical to diagnose due to its potential impact on hearing and neurological function.
- Otosclerosis: A condition in which there is abnormal bone growth in the middle ear, leading to hearing loss and ear fullness. Early diagnosis is crucial for effective treatment.
- Temporomandibular joint (TMJ) disorder: While not directly related to the ear, TMJ disorders can cause referred pain and sensations of fullness in the ear.
- Rare diagnoses
- Meniere's disease: A disorder of the inner ear that affects balance and hearing, causing episodes of vertigo, hearing loss, and ear fullness.
- Patulous Eustachian tube: A rare condition where the Eustachian tube remains open, leading to a sensation of fullness and autophony (hearing one's own breathing sounds).
- Superior canal dehiscence syndrome: A rare condition where there is an abnormal opening in the bone overlying the superior canal of the inner ear, leading to hearing and balance symptoms, including ear fullness.
