Objective:
To evaluate the therapeutic effect of dermis-fat graft combined with Medpor implant shaped by reverse engineering technique in the correction of the progressive hemifacial atrophy.
Methods:
A skull model was made by rapid prototyping and the bony deficiency model was acquired with reverse engineering technique. The Medpor implant was shaped precisely based on the deficiency model and implanted with dermis-fat graft at the same stage.
Results:
11 cases were treated successfully without infection, necrosis and rejection. The patients were followed up for six months to one year with satisfactory cosmetic improvement. The dermis-fat graft survived without obvious absorption.
Conclusion:
The technique can correct both the bony and soft tissue deficiency for progressive hemifacial atrophy. It is very practical and easily performed with reliant results and less morbidity.
