An evidence-based approach to augmentation mammaplasty

Practice Patterns in Primary Breast Augmentation: A 16-Year Review of Continuous Certification Tracer Data from the American Board of Plastic Surgery

BACKGROUND

As part of the continuous certification process, the American Board of Plastic Surgery collects case data for specific tracer procedures in aesthetic surgery to assess practice improvement by the diplomates. These case-based data provide valuable information on national trends in clinical practice. The current study was performed to analyze practice patterns in aesthetic primary breast augmentation.

METHODS

Breast augmentation tracer data were reviewed from 2005 to 2021 and grouped into an early cohort (EC), from 2005 through 2014, and a recent cohort (RC), from 2015 through 2021. Fisher exact tests and two-sample t tests compared demographic characteristics of the patients, surgical techniques, and complication rates.

RESULTS

Patients in the RC were slightly older (34 versus 35 years; P < 0.001), more likely to have ptosis greater than 22 cm (20% versus 23%; P < 0.0001), less likely to smoke (12% versus 8%; P < 0.0001), and less likely to undergo a preoperative mammogram (29% versus 24%; P < 0.0001). From a technical standpoint, inframammary incisions have become more common (68% versus 80%; P < 0.0001), whereas periareolar incision use has decreased (24% versus 14%; P < 0.0001). Submuscular plane placement has increased (22% versus 56%; P < 0.0001), while subglandular placement has decreased (19% versus 7%; P < 0.0001). Silicone implants are most popular (58% versus 82%; P < 0.0001). Textured implant use increased from 2011 (2%) to 2016 (16%), followed by a sharp decline to 0% by 2021. Trends follow U.S. Food and Drug Administration approvals and warnings.

CONCLUSIONS

This study highlights evolving trends in aesthetic breast augmentation over the past 16 years. The most common technique remains a smooth silicone prosthesis placed in the subpectoral plane through an inframammary incision.

Feasibility of Imaging Modalities Combined with a Silicone Gel-Filled Breast Implant in Korean Women

With the occurrence of breast implant crises in Korea, it has become increasingly important to detect complications earlier in patients receiving a device. We have therefore combined imaging modalities with an implant-based augmentation mammaplasty. In this study, we assessed the short-term treatment outcomes and safety of the Motiva Ergonomix™ RoundSilkSurface (Establishment Labs Holdings Inc., Alajuela, Costa Rica) in Korean women. A total of 87 women (n = 87) were included in the current study. We compared preoperative anthropometric measurements between the right side and the left side of the breast. Moreover, we also compared the thickness of the skin, subcutaneous tissue and the pectoralis major measured on a breast ultrasound preoperatively and 3 months postoperatively. Furthermore, we analyzed the incidences of postoperative complications and the cumulative complication-free survival. Preoperatively, there was a significant difference in the distance from the nipple to the midline between the left and right side of the breast (p = 0.000). Both sides of the breast showed significant differences in the thickness of the pectoralis major preoperatively and 3 months postoperatively (p = 0.000). A total of 11 cases (12.6%) of postoperative complications occurred; these included five cases (5.7%) of early seroma, two cases (2.3%) of infection, two cases (2.3%) of rippling, one case (1.1%) of hematoma and one case (1.1%) of capsular contracture. Time-to-events were estimated at 386.68 ± 27.79 days (95% CI 334.11–439.27). Here, we describe our experience with imaging modalities in combination with the Motiva ErgonomixTM Round SilkSurface in Korean women.

Four-Year Interim Results of the Safety of Augmentation Mammaplasty Using the Motiva Ergonomix™ Round SilkSurface: A Multicenter, Retrospective Study

BACKGROUND

The Motiva Ergonomix™ Round SilkSurface (Establishment Labs Holdings Inc., Alajuela, Costa Rica) is the fifth generation of a silicone gel-filled breast implant that is commercially available in Korea.

OBJECTIVES

In this study, we describe 4-year interim results of the safety of augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface in Korean women.

METHODS

In the current multicenter, retrospective study, we performed a retrospective review of medical records of a total of 1314 patients who received augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface at our hospitals between September 1, 2016, and August 31, 2020. For safety assessment, we analyzed incidences of postoperative complications and Kaplan-Meier complication-free survival of the patients.

RESULTS

We included a total of 873 patients (1746 breasts, mean age = 32.18 ± 6.88 years) in the current study. There were a total of 111 cases (12.70%) of postoperative complications; these include 24 cases (2.70%) of early seroma, 18 cases (2.10%) of hematoma, 18 cases (2.10%) of capsular contracture, 17 cases (1.95%) of dissatisfaction with shape, 16 cases (1.83%) of dissatisfaction with size, 9 cases (1.03%) of asymmetry, 6 cases (0.70%) of infection and 3 cases (0.34%) of rippling. Moreover, time-to-events were estimated at 918.34 ± 36.22 days (95% CI 845.44-988.52).

CONCLUSIONS

Here, we describe 4-year interim results of the safety of augmentation mammaplasty using the Motiva Ergonomix™ Round SilkSurface in Korean women in a non-manufacturer-sponsored study. But further large-scale, prospective, multicenter studies with a long period of follow-up are warranted to establish our results.

Short-term Safety of Augmentation Mammaplasty Using the BellaGel Implants in Korean Women

Supplemental Digital Content is available in the text.

Asian women are stereotypically characterized by a slim body, smaller breasts and areolae, and larger nipples when compared with White women. They would therefore be vulnerable to displacement of a breast implant if they receive larger implants. They are also prone to hypertrophic and prolonged hyperemic scars. Surgeons should therefore be aware of Asian women’s breast anatomy, healing tendency, and preferences. We conducted this multicenter, retrospective study to assess the short-term safety of the BellaGel implants in Korean women.

[Optimization of primary aesthetic breast augmentation using implants: an evidence-based level approach]

The primary aesthetic breast augmentation has been the most performed cosmetic surgery procedure in the world for over 40 years. The current literature focuses on the new concept of "process of breast augmentation" and the importance of non-surgical part (patient selection, preoperative planning and personalized management of postoperative care) in potentiating the cosmetic results and reducing the rate of complications and reoperations. This review of literature discusses, through an analysis of scientific evidence levels, every step of the whole process of breast augmentation in order to determine the current best practices tailored to each patient to optimize satisfactory and durable cosmetic outcomes.

Risk of breast implant bacterial contamination from endogenous breast flora, prevention with nipple shields, and implications for biofilm formation

BACKGROUND

Capsular contracture (CC) is a common complication of breast augmentation that is thought to arise from bacterial contamination and subsequent biofilm formation on the implant. Endogenous breast flora expressed through the nipple may contaminate the sterile field during breast augmentation, acting as a possible source for initiation of biofilm formation.

OBJECTIVES

The authors investigate the incidence of nipple bacterial contamination with endogenous breast flora after standard chest wall sterilization during breast augmentation.

METHODS

Bacterial contamination of nipples and nipple shields was assessed in a series of 32 consecutive patients presenting for breast augmentation (63 breasts: 31 bilateral procedures and 1 unilateral procedure). After standard sterilization of the chest wall, occlusive nipple shields were applied and breast augmentation was performed. At the conclusion of breast augmentation, the nipple shields were removed and, using the same swab, both the nipple/areolar area and occlusive dressings were cultured.

RESULTS

Data from 63 cultured nipples and nipple shields revealed that 22 nipples/nipple shields (34.9%) were positive for bacterial contamination. Three patients, all of whom had negative cultures, developed CC after augmentation.

CONCLUSIONS

The exposed nipple is a potential source of implant contamination during breast augmentation. An improved understanding of biofilms and related risk factors for CC can provide surgeons with insights for addressing this common complication. Meticulous hemostasis, use of nipple shields, and submuscular device placement may contribute to a lower incidence of CC.
