ABSTRACT:  Liquid injectable silicone is a unique soft tissue augmenting agent that may be effectively utilized for the correction of specific cutaneous and subcutaneous atrophies. Although historical complications have occurred, resulting likely from the presence of adulterants and impurities, modern purified silicone products approved by the Food and Drug Administration for injection into the human body may be employed with minimal complications when strict protocol is followed. In this article the present authors review the history and controversy regarding silicone as well as describe the appropriate indications, patient selection, instrumentation, treatment protocol, and anticipated complications involved with the use of liquid injectable silicone for soft tissue augmentation. Although its use is controversial, the present authors maintain that liquid injectable silicone is an important and effective augmenting agent for the long-term correction of scars and facial contour defects such as HIV facial lipoatrophy. Furthermore, it is a treatment modality deserving of continued investigation.
