ABSTRACT
Objective:
To evaluate the contour and functional restoration in segmental defects of mandibles with three-dimensional CT(3D-CT) reconstrction.Methods:
Twenty-four patients(16 males,8 females) underwent mandibular reconstruction by using nonvascularized bone grafts.In 24 patients,nonvascularized grafts from the iliac crests(n=11),the ribs(n=10),and the autogenous mandibular bones(AMB)(n=3)were used.`The length of segmental bone grafts ranged from 6 to 20 cm,with an average of 9.8 cm,for the defects with 5 to 20 cm.Both contour and functional effects with reconstructed mandible were determined and analysed via 3D-CT.Results:
All free bone grafts were successfully healed.Among them,17 patients showed better soft tissue contour.Only 14 patients were satisfied for skeletal contour.All patients could wear a conventional denture after reconstruction.Conclusion:
Facial contour can be achieved via mandibular reconstruction with iliac,rib and AMB.3D-CT can provide anatomy position for the surgical planning.It is an important mean to compensate inadequate of general X-ray and convention CT.Meanwhile it can be used for estimating the reconstruction effects while follow-up.
