Burow's advancement flap closure of adjacent defects.

When two surgical defects are closely approximated, primary closure may be difficult because of tension on the tissue between the defects. We outline a technique using a Burow's-triangle advancement flap in which the advanced Burow's triangle contains the second defect. The defects are easily closed with a single flap that utilized the second defect. This flap is useful when there are two closely approximated surgical defects of which primary closure is limited by tension on the tissue between the defects.
