Differential Diagnosis for Swollen Arytenoids
- Single most likely diagnosis
- Acute Laryngitis: This is the most common cause of swollen arytenoids, often resulting from viral infections, voice abuse, or irritants like smoke. The inflammation leads to swelling of the arytenoid cartilages, which can cause hoarseness, sore throat, and difficulty speaking.
- Other Likely diagnoses
- Gastroesophageal Reflux Disease (GERD): Stomach acid reflux can irritate the larynx, leading to inflammation and swelling of the arytenoids. This condition is common and can be exacerbated by diet, obesity, and other factors.
- Allergic Laryngitis: Allergic reactions can cause swelling and inflammation in the larynx, including the arytenoids, leading to symptoms like hoarseness and throat discomfort.
- Chronic Laryngitis: Prolonged exposure to irritants or persistent voice abuse can lead to chronic inflammation and swelling of the arytenoids.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Epiglottitis: Although less common, epiglottitis is a life-threatening condition that can cause significant swelling in the larynx, including the arytenoids, potentially leading to airway obstruction. It requires immediate medical attention.
- Laryngeal Cancer: While rare, cancer of the larynx can present with swelling of the arytenoids among other symptoms. Early detection is crucial for effective treatment.
- Rare diagnoses
- Relapsing Polychondritis: A rare autoimmune disorder that can cause inflammation and destruction of cartilaginous structures, including the arytenoids.
- Sarcoidosis: A condition characterized by the growth of granulomas in various parts of the body, including the larynx, which can lead to swelling of the arytenoids.
- Amyloidosis: A group of diseases that result from the abnormal accumulation of amyloid proteins in various tissues, including the larynx, potentially causing swelling of the arytenoids.
