Surgical techniques for temporary implantation of the electrical field-generating chin implant and percutaneous radiofrequency-induced tissue tightening have previously been described. The purpose of this study was to determine if a combination of the technologies to first, induce sustainable intramembranous bone remodeling, and second, treat neighboring tissue with liposuction and radiofrequency treatment is feasible, effective and safe. Six patients with mandibular hypoplasia, microgenia, submental and submandibular fat deposits, and excessive laxity of skin underwent surgical implantation of the battery-operated “chin-implant,” which generates negative polarity electrical pulses. After 12 months, satisfactory change of chin contours was induced and implants were removed. Cephalometric controls taken 3 to 6 months later showed an average increase of mandibular length 5.26 mm. Once sustainable bone remodeling was demonstrated, patients were subjected to the second stage of lower face contouring: Super wet syringe assisted liposuction and percutaneous radiofrequency treatment with generator inserted through existing liposuction stabincision. Subcutaneous tissue in the vicinity of the previous electrical field was liposuctioned in the same fashion as tissue not subjected to electrical field. No complications occurred in any of six patients. There were no cases of skin burns or seroma formation. Correction of the flaccid skin was striking in all cases with progressive tissue contraction and tightening that plateaued in two months. This study provides an encouraging option in contouring the lower face and neck, as it offers strengthening of bone lines, increased projection, change of soft tissue tone, and contour refinement with improved aesthetic line definition.
