Welcome to our information site about conditions and treatment of chest wall deformities

This site has been designed primarily to provide those with a chest wall deformity (pectus excavatum or sunken/funnel chest and pectus carinatum or pigeon chest) with informations about conditions and treatment options.

The senior pediatric surgeons

Sergio B. Sesia and

Frank-Mart Hä

are designated experts for chest wall deformities and members of the „Chest Wall International Group“ (CWIG). Frank-Martin Häcker is also member of the Executive Committee of CWIG.

CWIG was founded during The Second International Nuss Procedure Workshop held in Istanbul in June 2009 and consists of the most experienced surgeons who are studying, developing and innovating methods to treat chest wall diseases, such as: Horacio Abramson (Inventor of the minimal invasive surgical technique of pectus carinatum, Buenos Aires, Argentina); Hyung Joo Park (Seoul St. Mary’s Hospital, Seoul, South Korea); Marcelo Martinez-Ferro (Inventor of the Dynamic Compression System, Buenos Aires, Argentina); Donald Nuss (Inventor of the minimal invasive surgical technique of pectus excavatum, Norfolk, U.S.A.).

This site will also provide informations about the conservative treatment of

  • pectus excavatum with the Vacuum Bell developed by Eckart Klobe
