Breast augmentation: which is better — comparing silicone implants and fat grafting by complication rates

Many people are torn between 'implants or fat,' but the two differ in how much volume can be added, what complications may arise, and how they look 10 years later. Rather than choosing based on aesthetic preference, it becomes easier to decide when you recognize these as two different options with different risk profiles.

First, the big picture. Silicone implants allow you to reliably add a fixed volume, but in exchange you must manage complications arising from having a foreign object in your body for life — capsular contracture, rupture, and rare immune-related conditions. Fat grafting uses your own tissue, so you avoid foreign-body-derived risks, but a portion of the injected fat is always reabsorbed, limiting the volume that can be added and making graft survival harder to predict.

What silicone implants require you to manage

The greatest complication from implants is capsular contracture. This is a phenomenon in which the fibrous membrane encapsulating the foreign object shrinks and hardens — Aesthetic Plastic Surgery journal reviews identify it as 'the most frequent complication'[6]However, the incidence varies greatly depending on the technique. Adams et al. reported in over 42,000 cases.14-stepbacterial contamination minimization protocol (also known as the Adams 14-point plan) compliance group showed an average capsular contracture rate of2.2%has decreased to[1]. The idea is that suppressing infection and biofilm formation directly leads to contracture prevention.

Often overlooked is compatibility with radiation therapy. According to the guidelines of the Japanese Society of Plastic Surgeons, the incidence of complications such as infection, exposure, and severe capsular contracture is8–11%in the non-irradiated group, compared to24–42%is shown to increase significantly[4]. If there is a history of radiation exposure, such as in reconstruction after breast cancer treatment, the decision regarding implant (prosthesis) alone becomes cautious. As a rare condition, BIA-ALCL associated with textured (surface-modified) implant (prosthesis)s has been reported, and in the meta-analysis by Elameen et al., the risk is0-1 cases per 1000, which is approximately 28.9 times higher compared to the general population[5]. Although the frequency is low, including the long-term cohort of 3546 cases by Cordeiro et al.[8], it serves as a basis for regular follow-up monitoring.

Management on the fat injection side

Fat injection carries no risk of artificial materials. Instead, what we must contend with is absorption. Not all of the injected fat remains, and in a systematic review by Seth et al. (820 breasts), the average293ccwas injected and the remaining amount after one year averaged58.6%[7]. In other words, it is difficult to increase volume significantly in one session, and a change of approximately one cup size is a realistic range. Techniques to enhance retention are covered in detail in the next chapter (Episode 5), but choosing between the two breast augmentation approaches comes down to understanding it as a choice between two different options: "taking on the certain volume increase and artificial material risk" versus "accepting the natural appearance of your own tissue and the absorption risk." Detailed indications will be explained during your consultation.
