"Plastic Disasters" concludes with a caution that reads: "Over 9,000,000 cosmetic surgeries are performed each year in the United States. The total number of complications is not a matter of public record." But according to the American Society of Plastic Surgeons, an association of about 5,000 board-certified doctors, Americans had about 1.8 million cosmetic surgical procedures last year. And while it is true that no single national agency collects statistics on every problem caused by plastic surgery, researchers do publish data on complications. The filmmakers could easily have found a provocative number, for example, in a recent article in "Clinics of Plastic Surgery," which put the death rate from liposuction at one in 5,000 procedures. Still, the documentary is as gripping as any horror movie, and it offers a powerful counter to the sensational reality-television world of augmented physiques. "Plastic Disasters" makes clear that cosmetic surgery can change lives. But not always in the way that viewers of "The Swan" might expect.
