PURPOSES: To evaluate whether polyurethane foam leads more intense foreign-body reaction than silicone foam. To compare the vascularization of the capsules surrounding the foam implants. To investigate if the capsule of polyurethane foam implanted has greater amount of collagen than that of silicone foam. METHODS: Sixty-four young male Wistar rats were allocated into two groups: polyurethane foam and silicone foam. Subcutaneous discs were implanted into the dorsum of the animals in both groups. The capsules were assessed 28 days, two months, three months and six months postoperatively. Microscopic analysis with H&E stain was performed to evaluate the acute and chronic inflammatory process, foreign-body reaction and neovascularization. The analysis with picrosirius red was performed using the ImageProPlus software, to measure the number of vessels and collagen types I and III. RESULTS: There were no statistical differences between the two groups regarding the acute and chronic inflammatory processes. All rats from the polyurethane group, in all times, exhibited moderate or intense foreign-body reaction, with statistic significant difference (p=0.046) when compared with the silicone group, in which the reaction was either mild or nonexistent at two months. Vascular proliferation was significantly different between the groups at 28 days (p=0.0002), with the polyurethane group displaying greater neovascularization with H&E stain. Similar results were obtained with picrosirius red, which revealed in the polyurethane group a much greater number of vessels than in the silicone group (p=0.001). The collagen area was larger in the polyurethane group, significantly at 28 days (p=0.001) and at two months (p=0.030). CONCLUSIONS: Polyurethane foam elicited more intense foreign-body reaction when compared with silicone foam. The number of vessels was higher in the capsules of the polyurethane foam implants 28 days after the operation. The capsule of the polyurethane foam implants showed a greater amount of collagen than that of the silicone foam implants.

“…Twenty-three manuscripts describing a central mound dissection were identified, 2–24 beginning with a publication by Bames in 1950. 5 No randomized trials or prospective studies have been published. Because of the heterogeneity of the data and lack of controlled or comparative studies, a meta-analysis was impossible.…”

Background: The central mound approach to breast reduction has been the subject of recent interest in the literature. However, quantitative evaluation using measurements is lacking. This review was undertaken to objectively evaluate changes in breast dimensions, and to compare the results to a popular alternative method, vertical mammaplasty. Methods: An electronic search was performed using PubMed to identify all publications endorsing the central mound technique. Published lateral photographs were matched for size and orientation, with computer assistance. Measurements included breast projection, upper pole projection, lower pole level, breast mound elevation, nipple level, and breast parenchymal ratio. Results were compared with published measurement data for the vertical technique. Results: Twenty-three manuscripts were identified. Ten included photographs suitable for analysis. On average, breast projection decreased 1.1 cm after central mound breast reduction ( P < 0.05). Upper pole projection dropped 0.4 cm (not significant). The lower pole level was raised 2.6 cm ( P < 0.05). The nipple level was over-elevated 0.6 cm, on average. The breast parenchymal ratio increased by 0.54. A central mound dissection decreased breast projection. In contrast, publications using a vertical breast reduction demonstrated maintenance of upper pole and breast projection and a modest (<1 cm) increase. Conclusions: For each measurement comparison, the vertical method outperforms the central mound. Because of its anatomy and geometry, measurements show that the vertical method for breast reduction is more favorable than a central mound dissection. This method can also be used safely for secondary breast reductions.

“…This skin closure technique was also used by Biesenberger 24 and was widely adopted. 25 – 27 Aufricht 26 removed breast tissue from the upper pole, transposed the nipple, and used an inverted-T skin closure, relying on the “skin brassiere” to provide form. Biesenberger 24 and Maliniac 25 believed that the parenchymal dissection was most important for shape, not the skin covering.…”
