Mandibular contour reconstruction with three-dimensional computer-assisted models.

Facial contours are thought to depend on the appropriate balance of hard and soft tissue. To obtain aesthetically good results in head and neck reconstruction, surgeons should know the exact three-dimensional shape and volume of both hard and soft tissue to be reconstructed. The authors used computer-assisted three-dimensional solid models of the mandible in 7 patients (4 women and 3 men) who underwent mandibular contour reconstruction. Scapular osteocutaneous flaps were used in all 7 patients. The follow-up periods ranged from 7 to 57 months (mean follow-up, 29 months). No flap was lost. One patient died of metastatic cancer. In 2 patients the aesthetic results were excellent and in 4 patients they were good. Computer-assisted three-dimensional models for mandibular contour reconstruction in head and neck reconstruction are quite useful.
