Description

We have reported a case of using rib-latissimus dorsi osteomusculocutaneus flap in reconstruction of chest wall defects caused by osteonecrosis due to radiation.<br>The patient was a 68-year-old female who was admitted with myasthenia gravis. Twenty-seven years ago she was treated by cobalt irradiation. After the initial irradiation, radionecrosis developed in her sternum and the overlying soft tissues. Several sequestrectomies were required, therefore, she was referred to our department for reconstruction of the chest wall. CT examination revealed the extent of radionecrosis in her sternum. There was extensive loss of soft tissues. A latissimus dorsi compound myocutaneus flap, containing rib was then marked out. After the opertion, minor wound complication occured, but other postoperative complications including respiratory insufficiency was not seen with rib-latissimus dorsi osteomusculocutaneus flap.<br>In conclusion rib-latissimus dorsi osteomusculocutaneus flap seems to be a dependable method for chest wall reconstruction.
