An automatic reconstruction method of fibula for mandibular defect

Abstract

 Purpose: For patients who need to reconstruct the mandible with the fibula, this article gives an automated design scheme to save the doctor's time. Methods: First, perform the initial registration by analyzing the characteristic points of the fibula and jaw defect, cut the fibula and move it to the approximate location. Then optimize and adjust, and finally give a plan. Results The average operating time is about 10s for each reconstruction planning. Six surgeons at different levels were invited to rate the output of our method and manual operations by expert and novice, the evaluation of our method is even higher than that of the experts. Conclusions: The proposed method can automatically accomplish the task. At the same time, it is self-defining, allowing doctors to select the required feature points based on their own experience. This design has application value in the design of surgical plan.
