evaluation of 3d virtual analysis and free flaps in reconstruction of mandibular defects
Reconstruction of maxillo-facial defects creates a challenge for oral and maxillo-facial surgeons. It requires basic knowledge of anatomy and thorough skills for harvesting osseous and soft tissue to reconstruct the defective area. This work is a multi displinary which is done simultaneously for both resection and reconstruction.
To select and compare between different approaches for mandibular reconstruction with the aid of 3D virtual analysis.
A total number of thirty patients of different age groups complaining of different mandibular lesions were selected for resection and reconstruction of their defects either simultaneously or delayed after thorough investigations. The reconstruction will depend on many factors which include size, site of the defect, age and medical status of the patient, nature of the donor and recipient site.
Findings and Conclusion:
Immediate reconstruction is preferred than delayed one if it is feasible. In children preservation of the periostium is mandatory for self bone regeneration without harvesting bone graft. Micro-vascular bone grafting is the golden standard for reconstructing large bone defects while non vascularized iliac crest bone grafting is suitable for mild to moderate bone defects. Proper and accurate results require preoperative designing and planning through 3D virtual analysis and preparation of patient specific implant (PSI).
Rehabilitation of the reconstructed patient is mandatory as soon as possible for preserving bone, contour and facial symmetry by inserting dental implants with bridges or over dentures.
