Rotation flaps are a useful tool for reconstruction of skin defects in the scalp or limbs. Traditional methods of teaching rotation flaps in textbooks focus on the relationship of the circumference of rotation and the defect size. However, this neglects the importance of contour and arc of rotation, which can be a pitfall for trainees. Due to the extent of the incisions, a rotation flap that does not move as expected often results in the raising of a second flap. The method follows standard principles of design but utilizing fewer me, streamlining the teaching of these important flaps and producing predictable and reproducible outcomes. A detailed trigonometric proof is including, revealing this method of drawing rotation flaps achieves equivalent proportions to the standard rotation flap1. After triangulating the defect, this technique requires the marking of only 3 points initially using a point 1.5 times the length of a long side of the triangulated defect. This poster illustrates the step-by-step process of drawing rotation flaps using this method comprehensive trigonometric proof validating its equivalence to standard teaching of rotation flaps. This poster, aims to streamline the teaching of this valuable reconstructive technique in a clear and easily implementable approach, fostering enhanced precision and efficiency in rotation flap design for optimal aesthetic and functional outcomes in skin defect reconstruction. 1.
