IMPORTANCE Burow's advancement flap is a frequently used and versatile flap in cutaneous surgery because it provides an excellent method for repair of large defects in proximity to free margins. Its execution typically requires excision of 2 standing cones, which increases scarring and flap size. We describe a modification of this flap achieved with a simple, reproducible suturing technique that eliminates one of the standing cones and both minimizes suture lines and optimizes cosmesis at a variety of surgical sites.
