Background: The bilobed flap is a double transposition flap. Its geometric drawing allows a better distribution of tensile forces along its axis of rotation, avoiding distortions and dog ears generated by other flaps and primary closure. It can be harvested in an axial or random pattern depending on where the defect is located on the body. Methods: Retrospectively, this study reviewed 45 consecutive bilobed flaps searching for pathology, anatomical area, clinical evolution and complications. The technique utilized in drawing and harvesting the flap is described in detail. Sizes of the defects were classified as small, moderate and large, taking into account the anatomical sites. A variety of clinical cases is presented exploring the versatility of the flap and etiology of the defects. Results: The bilobed flap was employed in oncological surgery in 93% of the cases while the skin of the head was involved in 71%.The post operative period was free of complications in 85%. Infection rate was 4.4%, trapdoor scaring rate was 4.4% and partial flap loss rate was 11.1%. The overall complication rate was 15%. In spite of all complications there were no compromise in the functional and aesthetic results and the bilobed flaps proved to be resolute and reliable in different clinical presentations and body regions. Conclusions: The bilobed flap is extremely versatile, easily reproducible with wide application in plastic surgery.
