|A rib resection is the surgical removal of a segment of rib or ribs. Resection may be necessary to treat fractures that are at risk for damaging lung tissue, to remove sections of rib damaged by diseases such as cancer, or to obtain bone for a bone graft. A rib resection may also be performed as part of the treatment for thoracic outlet syndrome. Thoracic outlet syndrome results from the compression of blood vessels or nerve fibers between the neck and the axilla.|
Resection is commonly a part of surgical procedures that require access to the chest (thoracic) cavity. It is also done in the course of correcting a chest wall deformity called sunken chest (pectus excavatum).
Rib resection is a rare procedure.
