OBJECTIVE: To introduce a novel digital surgery technique based on partial reconstruction of skull and its application in tumor resection and on-sport reconstruction surgery.METHODS: The partial 3d reconstruction according to CT scanning data was obtained to get 3d model of both tumor and normal skull, then to define the resection area on tumor data through people-computer interaction process, do reconstruction the simulation on the remained model, pre-fabricate the cutting template and custom the implant. The resection template to confirm the message in surgery simulation can be transferred to real surgery accurately.RESULTS: All the four cases by using this method showed great consistency of the real and simulated surgery and got a good appearance of reconstruction.CONCLUSIONS: The surgery simulation technique based on partial 3d reconstruction has great assistance to tumor resection and one-stage reconstruction surgery.
