title: Allergan Style 410 Implants for Breast Reconstruction: A Prospective Study in Efficacy, Safety, and Symmetry.
abstract: BACKGROUND
  Implant-based breast reconstruction is performed with both saline and silicone. In 2001, a study was conducted in which a novel implant made of highly cohesive silicone gel in anatomical shape was used. It differs from others because it holds its anatomical shape and forces tissue to conform to the implant.
  
  
  METHODS
  Two hundred twelve consecutive patients who underwent reconstruction with Allergan 410 cohesive gel anatomical implants were enrolled prospectively over a 12-year period. Complications and satisfaction rates were recorded.
  
  
  RESULTS
  Average age of the patients was 48.5 years and average body mass index was 24.1 kg/m. Bilateral reconstruction was performed in 83 percent of patients. Long-term follow-up was achieved in all patients and averaged 3.3 years (range, 0.5 to 10.2 years). The overall complication rate was 19.8 percent; most were minor complications, such as rippling (9.4 percent) and asymmetry (4.2 percent). Major complications included infection (2.4 percent), malposition (1.4 percent), capsular contracture (0.9 percent), seroma (0.5 percent), extrusion (0.5 percent), and implant rupture (0.5 percent). The rate of implant-related reoperation, excluding cancer recurrence, was 9.0 percent, consisting of implant replacement (5.7 percent), implant removal (1.9 percent), and implant repositioning (1.4 percent). Patient satisfaction averaged 4.83 (range, 2 to 5) on a five-point scale. Surgeon satisfaction averaged 4.9 (range, 2 to 5).
  
  
  CONCLUSIONS
  Allergan 410 cohesive gel anatomical implants have a favorable risk profile in reconstruction, with excellent patient and surgeon satisfaction. This novel implant allows for a paradigm shift in implant-based breast reconstruction. Surgeons can now use an implant to help shape the final contour of the breast mound rather than rely on mastectomy flaps and suture techniques to create aesthetic contours needed to create an attractive breast reconstruction.
