“…Osteotomy of DCIA flap, introduced by Taylor and Watson [ 11 ] in 1978, requires a long operative time to obtain the desired curvature of neomandible and increases the risk of injury to the vascular pedicle, especially for surgeons without much experience. Mandibular reconstruction using virtual surgery planning and stereolithographic surgical guides is a recent introduction, especially in fibula free flaps [ 7 – 9 , 12 ], but, there are few reports with DCIA flap. However, current literature still relies on the surgeon’s experience to prevent errors.…”

“…However, current literature still relies on the surgeon’s experience to prevent errors. For example, although a virtual surgery planning is successfully implemented and a pre-bent reconstruction plate is prepared for the neomandible, to make the 3D shape of the neomandible using fibular or iliac bone flap is dependent on the surgeon’s experience [ 12 , 13 ] or the mirror image of the opposite side of the mandible [ 14 ] without surgical guides, not considering individual characteristics. Otherwise the reconstruction plate is pre-bent following the native mandible, rather than the neomandible, so it is difficult to achieve close contact between the reconstruction plate and bone flap.…”

Purpose:The reconstruction of mandibular defects poses many difficulties due to the unique, complex shape of the mandible and the temporomandibular joints. With development of microvascular anastomosis, free tissue transplantation techniques, such as deep circumflex iliac artery (DCIA) flap and fibular free flap (FFF), were developed. The DCIA offers good quality and quantity of bone tissue for mandibular segmental defect and implant for dental rehabilitation. Virtual surgical planning (VSP) and stereolithography-guided osteotomy are currently successfully applied in three-dimensional mandibular reconstruction, but most use FFF. There are only a few articles on reconstruction with the DCIA that assess the postoperative results.Methods:Three patients admitted during a five month period (April of 2013 to August of 2013) underwent resection of mandible and DCIA musculo-osseous reconstruction using a VSP and stereolithographic modeling and assessment of outcomes included technical accuracy, esthetic contour, and functional outcomes.Results:This technique yielded iliac bone segment with excellent apposition and duplication of the preoperative plan. Flap survival was 100 percent and all patients maintained preoperative occlusion and contour.Conclusion:Based on our experience, we offer considerations and logically consistent protocols by classification of mandibular defects, and demonstrate the benefits in VSP and stereolithographic modeling of mandibular reconstructive surgery with DCIA flap.

“…[24] However, the clinical implications and economic benefits have yet to be formally analyzed with the added cost of VSP-CAD/CAM in the context of various expanding clinical applications including trauma, temporomandibular joint reconstruction, cancer, and skull base surgery. [6,28,35,38] In head and neck cancer reconstruction, patient lifespan, risk for tumor recurrence and disease progression, and quality of life are additional factors that add complexity to the costbenefit evaluation of the technology in an oncologic setting.…”

“…The cutting planning may be useless if the discrepancy between the true cut and the prediction is large. Some researchers provided mechanisms (Strackee, 2004) or paper models (Wang, 2009) to record dimensions of the defect section to assist the osteotomy. However, those approaches require assistantship from technicians.…”

Using fibula flap for mandible reconstruction becomes a common method. Pre-surgical planning always assumes a known removal portion of mandible to plan the cutting of fibula. Researchers have developed jig or mechanism to assist doctors in measuring and guiding cutting locations of the mandible. However, the true locations of mandible removal are never known. To ease the problem, standard mandible parameters is required to locate the removal area. This paper aims to construct a reference line for parameterizing the mandible. The reference line can be divided into four portions that are coincident with the anatomical features areas of the mandible: Symphysis, Body, Angle, and Ramus. Each portion is then re-sampled into 10-15 sections, and these sections faithfully represent the mandible shape. Thus, all mandibles are redefined by these 101 sections. Using these mandible parameters, the removal area is recorded by numerical addressable locations to compute the fibula cut, and the mandible and fibula can be aligned according to the parameters for planning the reconstruction.
