Polymethylmethacrylate microspheres/collagen as a tissue augmenting agent: personal experience over 5 years.

BACKGROUND: Polymethylmethacrylate microspheres/collagen has been used in Canada since 1998. A closely related product will probably be approved in the United States shortly. Concerns have been expressed about the use of permanent fillers such as this. OBJECTIVE: This retrospective study of the authors' clinical practice is designed to reflect their experience with this agent. In particular, the authors describe some of the problems they have seen. RESULTS: Polymethylmethacrylate microspheres/collagen has behaved as a satisfactory long-term tissue augmenting agent in the authors' practice. They have had the opportunity of managing any number of patients with Artecoll granulomas and describe these patients. CONCLUSION: When polymethylmethacrylate microspheres/collagen is introduced to the United States, practitioners will need to learn how to use this exacting agent and will obtain excellent results with careful use.

Facial sculpting and tissue augmentation.

BACKGROUND: Until recently, deep facial sculpting was exclusively the domain of surgical interventions. Recent advances in the available array of dermal and subdermal fillers combined with an esthetic appreciation by both surgeons and nonsurgeons alike of the positive effect of filling the volume-depleted face have led to an expansion in the indications for the use of soft tissue augmenting agents. METHOD: Subdermal support of the lateral two-thirds of the brow, the nasojugal fold, the malar and buccal fat pads, the lateral lip commissures, and the perioral region, including the pre-jowl sulcus, all restore youthful facial contour and harmony. An important advance in technique is the subdermal rather than the intradermal injection plane. RESULTS: "Instant" facial sculpting giving a brow-lift, cheek-lift, lip expansion, and perioral augmentation is possible using modern soft tissue augmenting agents. The softer, more relaxed appearance contrasts to the somewhat "pulled" appearance of subjects who have had surgical overcorrections. Treatments can be combined with botulinum toxin and other procedures if required. CONCLUSION: Newer advances in the use of fillers include the use of fillers injected in the subdermal plane for "lunchtime" facial sculpting. Using the modern esthetic filler compounds, which are biodegradable but longer lasting, subjects can have a "rehearsal" treatment or make it ongoing. Some individuals, such as those with human immunodeficiency virus (HIV)-related lipoatrophy or those who desire to obtain a longer-lasting effect, may elect to use a nonbiodegradable filling agent.
