LEARNING OBJECTIVES: After studying this article, the participant should: 1. Be familiar with the medical uses of silicone. 2. Have a working knowledge of the most important epidemiologic studies regarding silicone gel-filled breast implants. 3. Be aware of the issues about which patients desiring breast augmentation or reconstruction with implants must be counseled.

The use of tobacco is a significant contributor to preventable morbidity and mortality in the United States. A significant proportion of cardiovascular diseases, various oral and pulmonary neoplasms, nonmalignant respiratory diseases, and peripheral vascular disorders can be attributed to the use of cigarettes. Surgical outcomes can also be adversely affected as a result of cigarette smoking with intraoperative and postoperative pulmonary, cardiovascular, and cerebrovascular complications as well as increased wound healing complications. These are found across the entire spectrum of surgical specialties. Tissue ischemia and wound-healing impairment secondary to the influence of tobacco is particularly problematic for the plastic surgeon, especially during elective facial aesthetic procedures, cosmetic and reconstructive breast operations, abdominoplasty, free-tissue transfer, and replantation procedures. By educating and providing guidelines to those patients who smoke and by refusing to operate on individuals who fail to abstain, tobacco-associated surgical morbidity in the plastic and reconstructive surgery patient can be eliminated.

What rhinoplasty surgeon has not been frustrated by unmet expectations from unreliable graft materials? The quest for an ideal graft continues. Septal cartilage is not always adequate in amount or substance. Ear cartilage may cause unsightly irregularities over time. Cranial bone or rib harvest sites add to the complexity of the procedure and can be intimidating for many operators. This article describes the authors' successful experience with AlloDerm onlay grafts for the correction of nasal contour deformities in 58 primary and secondary rhinoplasty cases by means of the open and endonasal approaches. Forty-two patients received an open-approach procedure; the remaining 16 received grafting through an endonasal or closed approach. Thirty-seven of the patients were secondary rhinoplasty patients, and some underwent multiple nasal corrections. The indications, intraoperative surgical technique of graft placement, and representative results will be discussed. Long-term follow-up showed good results, though partial graft resorption occurred in some patients. Overall, this experience with AlloDerm for nasal augmentation was encouraging.

True body sculpting demands a three-dimensional artistic understanding of the anatomic and surgical adipose layers of the central trunk when performing circumferential liposuction. This is essential in preventing complications from both ultrasound-assisted and suction-assisted lipoplasty. The authors describe five zones of adherence that should be avoided to prevent contour deformities in the central trunk area when performing circumferential liposuction. The anatomy of the subcutaneous tissue of these five anatomic zones is reviewed and correlated radiographically with magnetic resonance imaging studies. Aesthetic and technical considerations required to properly liposculpt the central trunk are demonstrated by case analysis of primary and secon-dary liposuction patients. These cases also delineate how to prevent and/or minimize deformities after liposuction.
