Abstract: Introduction: To avoid injury of the descending palatine artery during Le Fort I osteotomy, I believe that it is important to measure the right distance between the piriform rim and the most anterior point of the descending palatine canal on the CT images and to insert the chisel to the correct distance. To achieve this maneuver easily, a novel chisel with depth markings is developed. Material and methods The osteotome is based on a general thin osteotome of 6 mm width. Laser-striped markings are made for easy identification of 25, 27, 30, 33, 35, 37, and 40 mm from the top, with unique color-coded stripe. It enables easy bone-cut without anxiety in a short time. It is also a useful instrument for bone-cut where the length and depth are critical. Conclusion This length-marked osteotome is a reliable instrument for secure osteotomy without injuries.
