Quantitative assessment of the longevity of poly-L-lactic acid as a volumizing filler using 3-dimensional photography.

OBJECTIVE: To demonstrate the efficacy and longevity of injectable poly-L-lactic acid as a volumizing injectable in the midface region quantitatively using 3-dimensional (3-D) imaging. DESIGN, SETTING, AND PARTICIPANTS: Prospective study assessing changes in midfacial volume in 15 women aged between 40 and 60 years using a 3-D imaging system at 12, 24, 36, and 48 weeks after 3 treatments with poly-L-lactic acid. Three-dimensional imaging was acquired using the 3-D camera and software. INTERVENTION: Patients were treated with poly-L-lactic acid. The first 2 treatments were 6 weeks apart. The third treatment was performed 12 weeks after the second treatment. MAIN OUTCOMES AND MEASURES: Changes in midfacial volume following 3 treatments of poly-L-lactic acid were measured quantitatively using the 3-D imaging system. A paired t test was used to analyze the difference between pretreatment and posttreatment values at each study time point. RESULTS: Of the 15 patients, 1 only received 2 treatments and was therefore excluded from the statistical analysis. There was a statistically significant increase in mean midfacial volume at all study time points, 12 weeks (mean [range], 7.2 [1.6-20.7] mL; P < .001), 24 weeks (mean [range], 7.2 [1.9-19.4] mL; P < .001), 36 weeks (mean [range], 4.6 [1.1-9.2] mL; P = .002), and 48 weeks (mean [range], 4.1 [0.8-6.4] mL; P < .001), compared with pretreatment volume. There was no significant change in volume between each of the follow-up time points. CONCLUSIONS AND RELEVANCE: Our prospective investigation quantitatively demonstrates the efficacy of poly-L-lactic acid as a long-acting volumizing agent, with an increase in midfacial volume from baseline sustained at least 1 year after treatment. LEVEL OF EVIDENCE: 2. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01307865.

Multiple revenue streams from your existing and new practice opportunities: focusing on core values versus distractions.

The addition of profit centers to an existing or new plastic surgery practice has the potential to produce countless tangible and intangible rewards. It is important however, not to become engrossed in ventures that could distract from one's core business (i.e. aesthetic facial plastic surgery). This article relates some of the strategies taken from the popular business development literature to the setting of plastic surgery practice development.

Thread-lift for facial rejuvenation: assessment of long-term results.

OBJECTIVE: To evaluate the long-term success of the thread-lift procedure for facial rejuvenation. METHODS: Thirty-three patients underwent a thread-lift procedure alone or in combination with other facial rejuvenation procedures to the brow, midface, jowl, and neck. Ten patients underwent thread-lifts only, and 23 had thread-lifts with other procedures. Ten additional patients having had non-thread-lift rejuvenation procedures, including lipotransfer, chemical peels, and rhytidectomies, were randomly designated as controls. The mean follow-up period was 21 months (range, 12-31 months). Photodocumentation was obtained at each visit. Long-term aesthetic results were evaluated by 4 independent, blinded, and board-certified facial plastic surgeons. Each result was graded on a scale of 0 to 3, with 0 indicating no change; 1, minimal improvement; 2, moderate improvement; and 3, considerable improvement. The population was divided into 3 groups for comparison. Two-tailed t test (P = .05) was used for statistical analysis of aesthetic outcomes. RESULTS: Although aesthetic improvement was noted in all groups at 1 month, measurable results persisted to the end of the study for all but the group that underwent the thread-lift procedure only. Aesthetic improvement scores of the non-thread-lift control group were better than the group that underwent thread-lift only. Similarly, when the thread-lift was combined with other procedures, scores were better than when thread-lift was used alone. Statistical significance was demonstrated in both of these comparisons (P < .01). CONCLUSIONS: The thread-lift provides only limited short-term improvement that may be largely attributed to postprocedural edema and inflammation. Our results objectively demonstrate the poor long-term sustainability of the thread-lift procedure. Given these findings, as well as the measurable risk of adverse events and patient discomfort, we cannot justify further use of this procedure for facial rejuvenation.

The delivery of aesthetic medicine: illegal or not?

The field of aesthetic facial surgery is dynamic and may be driven by new technology and market trends. It is important that we respond to these pressures as small business persons, but only in the context of our obligations to our state regulatory boards, the Hippocratic Oath, and our patients' best interests. Regulations with regard to the scope of practice of aesthetic medicine and the corporate practice of medicine have the greatest potential to affect facial plastic surgeons. This article provides basic information regarding these medicolegal issues and resources to examine physician compliance. There may be an opportunity for the American Academy of Facial Plastic and Reconstructive Surgery to provide its membership with basic guidelines for scope of practice and corporate practice of medicine in an effort to optimize patient care.
