Ortner Syndrome: Understanding Its Causes and Treatment Options
Ortner syndrome, also known as cardiovocal syndrome, is a rare condition characterized by hoarseness resulting from left recurrent laryngeal nerve palsy due to cardiovascular disease. Know the various causes, symptoms, and complications associated with Ortner syndrome, as well as the strategies for diagnosis and management.
What is Ortner Syndrome?
Ortner syndrome is named after Norbert Ortner, the Austrian physician who first described the condition in 1897. It occurs when cardiovascular anomalies lead to compression or stretching of the left recurrent laryngeal nerve, causing vocal cord paralysis. This condition is often indicative of underlying cardiovascular diseases, making it crucial to understand its origins and implications for overall health.

Ortner syndrome is primarily caused by cardiovascular disorders. The most common causes include:
- Left Atrium Enlargement: Conditions such as mitral stenosis or regurgitation can cause the left atrium to enlarge, exerting pressure on the adjacent left recurrent laryngeal nerve.
- Aortic Aneurysm: An enlargement of the aorta can lead to nerve compression, resulting in the symptoms of Ortner syndrome.
- Pulmonary Hypertension: Elevated pressure in the pulmonary arteries can indirectly affect the left recurrent laryngeal nerve by altering the anatomy of the surrounding structures.
- Congenital Heart Defects: Certain congenital anomalies can predispose individuals to this syndrome by affecting cardiovascular structures in proximity to the laryngeal nerve.
- Other Rare Causes: Conditions such as mediastinal tumors or significant thoracic injuries may also lead to Ortner syndrome, although these are less common.
Recognizing Ortner Syndrome Symptoms
The hallmark symptom of Ortner syndrome is hoarseness or a change in voice. However, this condition may present with other symptoms that reflect its cardiovascular roots:
- Hoarseness: Resulting from paralysis of the vocal cords due to nerve impairment.
- Shortness of Breath: Associated with underlying cardiac or pulmonary issues.
- Cough: Often persistent and unexplained by other respiratory conditions.
- Dysphagia: Difficulty swallowing, which can occur due to nerve involvement affecting the esophagus.
It is crucial for healthcare providers to differentiate these symptoms from other causes of vocal cord paralysis to ensure an accurate diagnosis.
Diagnosing Ortner Syndrome
Clinical Evaluation
Diagnosis begins with a thorough clinical evaluation, including a detailed patient history and physical examination. Key aspects include:
- Medical History: Understanding any history of cardiovascular disease or symptoms that might correlate with nerve compression.
- Voice Assessment: Evaluating the degree of hoarseness and its impact on the patient's quality of life.
Imaging Studies
Imaging is essential to confirm the diagnosis and identify underlying cardiovascular conditions:
- Chest X-ray: May reveal cardiac enlargement or pulmonary abnormalities.
- Echocardiography: Provides detailed images of the heart's structure, helping to identify atrial enlargement or other cardiac issues.
- CT or MRI: Offers detailed visualization of the mediastinum and thoracic structures, which can pinpoint the exact cause of nerve compression.
Laryngoscopy
A laryngoscopy may be performed to directly visualize the vocal cords and assess their function. This helps confirm nerve paralysis and rule out other laryngeal pathologies.
Ortner Syndrome Treatments
Medical Management
The treatment of Ortner syndrome primarily focuses on addressing the underlying cardiovascular condition. Options may include:
- Medications: To manage heart conditions such as hypertension or heart failure, potentially reducing nerve compression.
- Lifestyle Modifications: Dietary changes, exercise, and smoking cessation can improve overall cardiovascular health.

In cases where medical management is insufficient, surgical options may be necessary:
- Cardiac Surgery: Procedures such as mitral valve repair or replacement can alleviate atrial enlargement.
- Aortic Repair: Surgical intervention may be required for aortic aneurysms to prevent further nerve compression.
- Voice Therapy and Laryngeal Surgery: In some cases, vocal cord function may improve with targeted therapy or surgical interventions to restore voice quality.
Long-term Management and Follow-up
Ongoing management of Ortner syndrome involves regular monitoring of cardiovascular health and vocal function. Patients should have routine follow-ups with both cardiology and otolaryngology specialists to manage symptoms and prevent complications effectively.
Complications of Ortner Syndrome
While Ortner syndrome itself is primarily a manifestation of underlying cardiovascular issues, it can lead to complications if not properly managed:
- Progression of Cardiovascular Disease: Without treatment, the cardiovascular condition causing Ortner syndrome may worsen, leading to more severe health issues.
- Permanent Vocal Cord Damage: Prolonged nerve compression can result in irreversible vocal cord paralysis.
- Quality of Life Impact: Persistent hoarseness and associated symptoms can significantly affect a patient's daily life and emotional well-being.
