ABSTRACT
<p><b>OBJECTIVE</b>To study the sternocleidomastoid-clavicle myocutaneous flap (SCMCP) for repairing the compound operative defect after oral carcinoma resection, to observe its clinical effect, prognosis and advantages of SCMCP, and to develop a new operative method that implantation of dental implant can be performed simultaneously.</p><p><b>METHODS</b>Sixteen patients underwent reconstruction with SCMCP after oral carcinoma resection and neck dissection during 2007 to 2009. Four of them (25.00%) underwent simultaneously implantation of dental implants in the clavicular flaps.</p><p><b>RESULTS</b>None of these patients died postoperatively during the follow-up until now. One patient (6.25%) with buccal cancer encountered local recurrence resulting in reoperation, and the flap grows well up to now. A part of the skin paddle underwent necrosis in two patients (12.50%), local fluidity was found in 2 patients (12.50%), fracture of clavicle occurred during the operation in one patient (6.25%). All the patients had good pronunciation and oral diet with no difficulty.</p><p><b>CONCLUSION</b>SCMCP is easy to survive, simple to perform, the clavicular figure and function won't be destroyed significantly. SCMCP is a good operative method to repair the compound operative defect after oral carcinoma resection.</p>

Objective To apply the techniques of CAD/CAM in the repair of defects and correction of deformity on the jaw bones so as to improve the accuracy and controllability of operations.Methods With CAD techniques,3D bone model was reconstructed based on CT images.Then,a repairing model was created with mirror operation on original model.The physical models of original model and repairing model were fabricated through rapid prototyping.Based on physical models,operation plan and model surgery with pre-forming plate could be designed.Results The designed operation plan and pre-forming plate techniques of CAD/CAM were successfully applied in eight patients,with satisfactory results.Conclusions With techniques of CAD/CAM,reconstructing and fabricating the original bone model and mirror repair model are very helpful for designing operation plan for maxillofacial surgery.It also can improve the surgery accuracy and save operation time obviously.
