Treating Parry-Romberg Syndrome Using Three-Dimensional Scanning and Printing and the Anterolateral Thigh Dermal Adipofascial Flap.

BACKGROUND

As three-dimensional technology becomes more ubiquitous, many plastic surgical applications have emerged. The authors investigate a three-dimensional scanning and printing system for facial soft tissue reconstruction in conjunction with an anterolateral thigh dermal adipofascial flap for the treatment of Parry-Romberg syndrome.

METHODS

Seven patients with facial atrophy of the zygomatic, buccal, and mandibular areas were included. Three-dimensional scanning of each patient's face in conjunction was analyzed with computer-aided design (CAD) to quantify areas of facial asymmetry. Models were then created using three-dimensional printing to map areas of soft tissue deficiency. Free anterolateral thigh (ALT) dermal adipofascial flaps were designed based on the three-dimensional models of soft tissue deficiency.

RESULTS

All flaps survived. One case had a postoperative hematoma. Six patients had restored facial symmetry. One patient required fat injections to obtain symmetry. No patients required revision surgery of their healed flaps for contouring.

CONCLUSIONS

Three-dimensional laser scanning and three-dimensional printing in combination with a free ALT dermal adipofascial flap offer surgeons a precise means to reconstruct facial contour deformities.
