Background Most skin flaps are designed to repair circular surgical defects after skin tumor excisions, but few flaps have been described to reconstruct triangular defects. Objective The aim of this study was to describe new skin flaps for triangular surgical defects using an innovative experimental model. Methods We tested new flap designs in an experimental pig skin model using a tension sensor to measure maximum tension and tension augmentation when the flap is performed in an area of increased basal tension. The results were compared with those from classic flaps. Finally, the new flaps were performed on a series of patients with triangular surgical defects. Results Six new flaps with adequate levels of tension were obtained and named after their morphology: spider crab, mantis, toy windmill, nautilus, origami bird, and clover. These new flaps were successfully performed on a series of 40 patients; among them, spider crab and mantis flaps showed a better response to basal tension augmentation. Conclusions Six new flaps for triangular surgical defects were proposed and successfully performed in a series of 40 patients, using an experimental pig skin model and a tensiometer.
