Parry-Romberg reconstruction: beneficial results despite poorer fat take.

OBJECTIVE: For the treatment of Parry-Romberg syndrome or progressive hemifacial atrophy, we studied the volume retention and skin changes after autologous fat grafts within diseased regions.

SUMMARY BACKGROUND DATA: The long-term survival and volume retention of fat grafts used in soft tissue reconstruction of Parry-Romberg syndrome is still unknown, as are skin changes after fat grafting.

METHODS: Sex, age, severity of deformity, number of procedures, operative times, and augmentation volumes were recorded. Preoperative/postoperative 3-dimensional computed tomographic scans were also reviewed. A digital 3-dimensional photogrammetry system was used to determine "final fat take" and symmetry. Romberg fat grafting volumes were compared to nonaffected, cosmetic fat-grafted patients. For skin changes, a spectrophotometer was used to quantify percent improvement in melanin index. Physician and patient satisfaction surveys (5-point scale) were elicited, including overall outcome and skin color/texture.

RESULTS: The mean number of procedures correlated to the severity of deformity: mild, 1.8 procedures; moderate, 3.4; and severe, 5.2. With Romberg patients, fat grafting injected: per case, 48 mL; total, 188 mL; and final measured volume, 101 mL. Romberg patients had less "fat take" than nonaffected grafted patients (final take, 41% vs 81%). Skin color/texture showed 3-fold improvement after fat grafting procedures. The mean melanin index improvement seen in the diseased regions of Romberg patients after fat grafting was 42% (+3%). Skin color and texture improvement was also shown in patient surveys (preoperative = 2.4 + 0.06 to follow-up = 3.4 + 0.09) and physician (preoperatively = 2.1 + 0.1 to follow-up = 3.6 + 0.1).

CONCLUSIONS: Despite poorer fat graft take within the disease region of Romberg patients, fat grafting resulted in long-term improvement in hypoplasia and skin hyperpigmentation.
