ABSTRACT
BACKGROUND:
Progressive hemifacial atrophy (PHA) is a rare disease characterized by progressive atrophy of skin, soft tissue, muscles, and underlying bone structures. For severe PHA patients with obvious bone deformities, skeletal framework reconstruction is needed in addition to soft-tissue augmentation. The authors propose a new combinatorial surgical method using rib cartilage graft and free adipofascial flap for restoring facial symmetry. To improve the surgical accuracy, preoperative three-dimensional planning and printing was used.METHODS:
Twelve patients with severe facial atrophy were included in the authors' study. Three-dimensional facial image analyses were performed preoperatively to quantify the facial asymmetry. Rib cartilages were harvested and sculptured to the appropriate shape created by three-dimensional planning and fixed to the atrophic bone. The circumflex scapular artery-based adipofascial flap was transplanted to repair soft-tissue deficiency. A residual small monitor flap was left with the adipofascial flap. A revision surgery was performed to perfect the repair if the contour was suboptimal 6 months postoperatively.RESULTS:
The adipofascial flaps survived in all 12 patients. All patients achieved good healing without complications. At 1 more year after surgery, the rib cartilage was still in position and rarely absorbed. The morphologic and volumetric difference between the affected side and the unaffected side was improved significantly postoperatively. All patients were satisfied with the results, and no more additional operations were required.CONCLUSION:
The combinatorial surgery of rib cartilage graft and free adipofascial flap in the setting of three-dimensional planning and printing can be a good choice in restoring facial symmetry in severe cases of PHA. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.
