Titanium plates salvage in irradiated facial areas with the lipomodeling technique

Abstract

Major defects of the facial structures cause severe functional and aesthetic impairment. For composite defects with bone loss, the use of a titanium plate bridging the bony defect, associated or not to a soft tissue pedicled flap is to be considered in complex cases, or for patients with high comorbidities. The principal limit of this technique is the risk of plate exposure, especially for patients who had adjuvant radiation therapy. We present two clinical cases of patients who had a facial reconstruction using a titanium plate associated with a locoregional soft tissue flap, and who presented a near-exposed plate a few years after the first surgery and adjuvant radiation therapy. In order to prevent plate exposure, we performed several lipomodeling sessions between skin and plate. Our results are very encouraging, with no plate exposure and thickening of the soft tissues which cover the plate at 10-years follow-up. The knowledge of the possibility to use fat grafting transfer could therefore lead to a strong return to the use of titanium plates in facial reconstruction.
