Minimal invasive reconstruction of posttraumatic hemi facial atrophy by 3-D computer-assisted lipofilling

SummaryFacial hemi atrophy is seen after trauma, Parry-Romberg syndrome and on other rare occasions. Since the aesthetic deficit is very obvious and irritating, facial reconstruction is often requested by these patients. In most cases the only option for sufficient reconstruction is free flap reconstruction, which represents the standard treatment. Recently in plastic surgery, various new techniques have been developed with the potential for multiple applications. Lipofilling has been presented primarily for the correction of cosmetic lesions or the reconstruction of minor soft tissue defects, but even reconstruction of larger soft tissue deficits is possible. The concept of using 3-D technology in facial reconstruction has multiple advantages. Primarily, the ideal final aesthetic outcome can be simulated by virtual reconstruction. Mathematic calculations deliver exact numbers in volume deficits, enabling precise planning of soft tissue substitution especially in lipofilling, ideally avoiding unnecessary corrections. Since autologous soft tissue reconstruction represents a dynamic process with periods of swelling as well as atrophy, quality control is required for achieving optimal results. Use of 3-D scanning has the advantage of reliable visualisation in soft tissue reconstruction without the limitations of harmful side effects.We present the history of a female suffering from the posttraumatic consequences of head injuries related to a car accident and the successful correction of her hemi facial atrophy by autologous lipofilling. Technical details and the potential of 3-D scanning in plastic surgery are discussed.
