Abstract:
Facial contouring surgeries (reduction malaroplasty, mandibularoplasty and osseous Genioplasty) are common procedures in East Asians. Unsatisfied results (over-correction, under-correction and asymmetry) may happen due to limited visual field through intra-oral incision. Conventional surgical planning was performed with Cephalometry and panorax imaging and three-dimensional evaluation with computed tomography became more popular. The advent of virtual surgical planning (VSP) in maxillofacial surgery has aided surgeons and patients by processing pre-surgical planning precisely and improving accuracy of surgery.
In this article, the author would focus on the use of computed-assisted simulation system in planning of malaroplasty and mandibularoplasty. The choice of procedure, sequence of planning, design of osteotomy, and execution of virtual planning in theater would be illustrated. The accuracy of surgical results would be assessed by superimposing the postoperative CT imaging to with the simulation imaging.
Conclusion:
Our finding suggests that application of virtual surgical planning in facial contouring surgery could reduce operation time and increase the accuracy of the surgery.
