Mounier-Kuhn syndrome



Other Names:
Congenital tracheobronchomegaly; Mounier Kuhn syndrome
Categories:

Mounier-Kuhn syndrome is a lung disorder that causes the respiratory tract to dilate or enlarge. People with this condition develop frequent respiratory tract infections and recurrent cough. The condition can be diagnosed by lung function testsbronchoscopy, and a chest CT scan.[1] The cause of Mounier-Kuhn syndrome is unknown, although cigarette smoke and air pollutants may act as irritating factors. Some cases are associated with connective tissue diseases such as Ehlers-Danlos syndrome, Marfan syndrome, and cutis laxa and may be inherited.[2] Treatment typically involves chest physical therapy and antibiotics to treat infections.[1][2]

Management Guidelines

  • Project OrphanAnesthesia is a project whose aim is to create peer-reviewed, readily accessible guidelines for patients with rare diseases and for the anesthesiologists caring for them. The project is a collaborative effort of the German Society of Anesthesiology and Intensive Care, Orphanet, the European Society of Pediatric Anesthesia, anesthetists and rare disease experts with the aim to contribute to patient safety.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.
