The lateral thoracic region flap.

The lateral thoracic region flap is based at the level of the 3rd rib on multiple direct cutaneous perforators. It has an excellent vascularity with a dependable length/width ratio of 3:1. The donor area, which lies in a concealed region, can often be closed primarily. The flap is hairless and can be used anteriorly to cover raw areas over breast and axilla and posteriorly over scapula and chest wall. As a distant flap it can be used to resurface raw areas on the ipsilateral upper arm and forearm and contralateral hand. The successful use of the flap in 40 cases in this series confirms its reliability, versatility and convenience.
