以下這篇文章其實不是特別討論這個問題,而是在比較法國廠的Poly Implant 與美國廠的 Mentor 義乳,在四年內破掉的比率有多少?

Title A Comparison of 500 Prefilled Textured Saline Breast Implants versus 500 Standard Textured Saline Breast Implants: Is There a Difference in Deflation Rates?

Source Plastic & Reconstructive Surgery. 117(7):2175-2178, June 2006.

Abstract
Background: This study provides the first large-volume (1000 implant) comparison of the deflation rates of Poly Implant Prosthesis prefilled textured saline breast implants versus a control group of Mentor Siltex textured saline implants.

Methods: A consecutive series of 500 Poly Implant Prosthesis prefilled textured saline breast implants was compared with a consecutive series of 500 Mentor Siltex breast implants. Each breast implant was evaluated for a 4-year period, and the annual deflation rate (number of deflations during a given year divided by the total number of implants) and cumulative deflation rate (cumulative total of deflations through a given year divided by the total number of implants) were recorded. Statistical significance was calculated using the Fisher's exact test at year 1 and the chi-square analysis at years 2 through 4.

Results: The cumulative deflation rates of the Poly Implant Prosthesis implants was as follows: year 1, 1.2 percent; year 2, 5.6 percent; year 3, 11.4 percent; and year 4, 15.4 percent. The cumulative deflation rates of the Mentor implants was: year 1, 0.2 percent; year 2, 0.6 percent; year 3, 1.6 percent; and year 4, 4.4 percent. At year 1, the difference between deflation rates was not statistically significant (Fisher's exact test, p > 0.05). However, at year 2 (chi-square, 13.29; p < 0.001), year 3 (chi-square, 37.91; p < 0.001), and year 4 (chi-square, 32.69; p < 0.001), the difference was statistically significant.

Conclusions: There was a statistically significant difference between the overall deflation rates of Poly Implant Prosthesis prefilled textured saline breast implants and Mentor Siltex breast implants at year 2, year 3, and year 4. After 4 years, the 15.56 percent cumulative deflation rate of Poly Implant Prosthesis implants was over 3.5 times higher than the 4.31 percent deflation rate of the Mentor Siltex implants. There may be several factors contributing to the higher deflation rate seen in Poly Implant Prosthesis implants, including possible in vitro deflation before implantation and silicone shell curing technique. Nevertheless, this statistically significant deflation difference must be taken into account when balancing the risks and benefits of Poly Implant Prosthesis breast implants.

結果是美國廠 Mentor 勝出。
我們做個簡表,來總括本文
---------------------------------------------------------------------------
.................. 1年內破掉.......2年內破掉.......3年內破掉........ 4年內破掉
法國Poly.........1.2%.............5.6%..............11.4%............15.4%

美國Mentor......0.2%............0.6%................1.6%............4.4%

----------------------------------------------------------------------------

相信自己有隆乳的人一定很擔心,自己是用那家的產品呢?
若是你在台灣做的,大概可以放心,國內似乎沒有引進法國 Poly 品牌;
而台灣使用Mentor 者大約有3~4成左右。另外約有3~4成是使用McGhan(或稱 Inamed 也是美國公司),有2成左右使用Nagor。(以上是筆者自行估計)

不過,即使你使用的是Mentor或McGuan這種名牌義乳,四年內破掉的機會還是有4%左右,這點風險要謹記。
