Study of breast enlargement with Silicone Implants - DiagonGel® Implants with PU coating: High level of shape stability, natural results and low rates of complications

Dieburg, in November 2017. The results of the Study(1) on the use of DiagonGel® Implants with Polyurethane foam coating (PU) for breast augmentation were published in July 2017 on the online platform "Global Open" of the renowned PRS Journal.

DiagonGel® Implants are anatomically contoured and filled with two differing types of silicone gel: a soft gel on the rear side and a more firm gel on the front side. The more firm Shapar Gel in the front part of the Implant supports the tissue similarly to a Push-up-bra, which ensures an aesthetically natural result. Additionally the shape of the breast as well as the position of the nipple is thereby preserved for the long-term.

A further benefit is the special design of the Implant with spherical projection and stable caudal edges. The Implants also boast a coating of PU foam, which is characterised by extremely low rates of complications according to the latest studies(2),(3).

DiagonGel® Implants with PU coating are produced exclusively in Germany by the POLYTECH Health & Aesthetics GmbH, located in Dieburg (Hessen). Due to the proven high level of tolerability of this implant, risky and cost intensive reoperations as a result of capsular contracture or an implant dislocation, amongst others, can be largely avoided.

The results of the study: Low rates of complications and capsular contracture

The study which was carried out under the direction of Constantin Stan (and Thomas Biggs) and refers to around 1,800 PU coated DiagonGel® Implants and 894 patients, who underwent post operative examinations over a period of more than 5 years. The findings show that DiagonGel® Implants with PU coating markedly reduce the risk of a capsular contracture, and exhibit generally reduced complication rates. In fact no capsular contracture was encountered in the time period of the study (Baker-Grade III or IV). Furthermore no complications caused by implant rotation or dislocations were documented. Also the amount of late seromas, two cases after three years, lies well under the average.

Very high level of overall tolerability and stable aesthetic results

"I work almost exclusively with this type of implant, both in primary augmentation as well as in reoperations. For one thing I can completely avoid complications caused by the occurrence of implant rotation or dislocation. Another point is that capsular contracture is, in my experience, indeed lower than that seen with other types of implants," explains Dr. HansPeter Heckel, specialist for plastic and aesthetic surgery in Bayreuth.

"Furthermore the long term shape stability through the differing silicone gel consistency and the special anatomical shape is markedly better than that of other implant types,” continues Heckel.

  1. EasyFit GelTM — softer cohesive gel for smooth fit to rib cage
  2. Shapar GelTM — firmer cohesive gel for tis- sue push-up effect
  3. Prevention of delamination of gel or shell, high gel integrity
  4. Nipple position
  5. Maximum implant projection at 25%
  6. Firmer gel at the bottom eliminates gel roll
  7. Easy nipple positioning due to levelled dome- shaped projection

Implementation with "Pseudo ptosis" without additional lifting operation

"I have had very good experiences from PU coated DiagonGel® Implants with patients exhibiting slight ptosis i.e. grade 1 or 2. When the implants are combined with a so-called internal lifting during which the mammary gland is fixated and the implant is placed under the musculature, then an additional lifting operation can be dispensed with in most cases", finishes Heckel.

This "Multi level method“, which was developed by the study director Constantin Stan, means that additional scars, which would occur in the course of a lifting operation, can be avoided.
