Cohesive breast implants or silicone gel-filled implants are the popular choice among breast augmentation and reconstructive patients due to their natural results and feel, says leading Inland Empire plastic surgeon Dr. Tarick Smiley.
Saline implants, meanwhile, have no tinge of cohesiveness since they are only filled with saline—i.e., sterile saltwater.
In a recent Snapchat video, Dr. Smiley has explained the three levels of cohesiveness of round silicone implants manufactured by Allergan, a US-based company known for its FDA-approved, high-quality products.
- Least cohesive silicone implants (Natrelle INSPIRA Responsive)
According to company brochure, they result in 84 percent upper pole retention once placed inside the breast pocket. Despite being the least cohesive type in the line of silicone breast implants, they nonetheless provide more natural results than saline implants.
Regardless of the level of cohesiveness, it is important to choose implants that reflect the patient’s chest and breast dimension to achieve natural results and to avoid a wide range of surgical stigmata.
- Moderately cohesive silicone implants (Natrelle INSPIRA SoftTouch)
While they provide 91 percent upper pole retention, they nonetheless remain soft to the touch thanks to their cohesive silicone gel filling. Of course, they are slightly firmer than Natrelle INSPIRA Responsive.
- Most cohesive or “gummiest” version (Natrelle INSPIRA Cohesive)
They retain 97 percent of their upper pole, resulting in additional fullness in the upper cleavage; hence, they suit patients who want the “push-up bra effect.” Also, women with low body fat percentage or lack breast tissue, anatomy that predisposes them to higher risk of implant rippling, are good candidates for this gummiest version of silicone implants.
One caveat of this gummiest version is the firmer breast, although most patients who are at risk of implant rippling do find this tradeoff acceptable.
The most cohesive type also suits women seeking a revision breast augmentation to correct implant rippling, which commonly occurs around the upper breast pole where the tissue is the thinnest.
