Pilonidal sinus disease (PSD) is an acquired chronic infection that commonly involves the natal cleft, is difficult to treat and has high recurrence after surgery. The parasacral perforator flap is a useful and effective flap for coverage after excision of disease. However, it requires technical expertise and specialised equipment. We have modified the technique by leaving the base of the flap, the perforator and surrounding tissue and fat intact, making the procedure easier for general or plastic surgeons to perform.
