Round Form-Stable Breast Implants: Diagnosis and Management of Complications

Reasons for Silicone Breast Implant Removal After Long-Term Implantation in Chinese Patients Without Complications: A Questionnaire-Based Study

BACKGROUND

There are few studies of Chinese patients who request silicone breast implant removal after at least 10 years of implantation without any complications. This study aimed to study the characteristics of these patients, explore their reasons for breast implant removal and associate factors that affect their choice, so as to provide valuable information on clinical decision making.

METHODS

A total of 55 eligible female patients (110 breasts) were enrolled from 2016 to 2022. A preoperative questionnaire survey before removal surgery and a telephone follow-up 1 year after removal surgery were conducted to collect data.

RESULTS

The mean age of the patients was 40.6±8.8 years with the average time from breast augmentation to implant removal or replacement ranged from 10 to 15 years. Concerns about the aging of silicone gel-filled breast implant and the adverse effects of its long-term placement on body health were the top two reasons for breast implant removal. 63% of patients refused implant replacement, who were nearly 10 years older than those accepted implant replacement (p<0.05). Older age at implant removal (OR=0.67; 95%CI: 0.44-0.89) and a history of basic diseases (OR=0.02; 95%CI: 0.00-0.39) were statistically associated with lower rate of implant replacement.

CONCLUSIONS

Concerns about the aging of silicone gel-filled breast implant were the main reason for uncomplicated patients to remove their breast implants. A comprehensive analysis based on patient's subjective choice and physical condition was suggested when an uncomplicated patient asks for implant removal.

Complication Rates in Therapeutic Versus Prophylactic Bilateral Mastectomies: Insights From a National Database

BACKGROUND

The "Jolie effect" and other media focus on prophylactic treatments have resulted in unilateral breast cancer patients increasingly undergoing contralateral prophylactic mastectomy. Little is known, however, regarding outcomes following therapeutic versus prophylactic mastectomy. In this study, we compared complication rates of unilateral breast cancer patients undergoing contralateral prophylactic mastectomy (BM-TP) to patients undergoing bilateral prophylactic mastectomy (BM-P).

METHODS

The BM-TP and BM-P patients from 2015 to 2019 were identified in Optum Clinformatics DataMart. Six-month outcomes were assessed and included wound complications, infection, hematoma/seroma, breast pain, fat necrosis, flap failure, implant failure/removal, other flap/implant complications, and other complications. Multivariable regression models adjusted for age, residence, insurance, race, and Charlson Comorbidity Index score.

RESULTS

Of 9319 women, 7114 (76.3%) underwent BM-TP, and 2205 (23.7%) underwent BM-P. In multivariable analysis, BM-TP had higher odds of overall complications (adjusted odds ratio [aOR], 1.35; P < 0.0001), but no difference was observed among patients who had autologous ( P = 0.1448) or no breast reconstruction ( P = 0.1530). Higher odds of overall complications persisted even after controlling for radiation therapy (aOR, 1.25; P = 0.0048) and chemotherapy (aOR, 1.28; P = 0.0047), but not after controlling for lymph node surgery ( P = 0.7765).

CONCLUSION

The BM-TP (vs BM-P) patients face higher odds of overall complications but without any difference in certain reconstructive modalities or after controlling for lymph node surgery.

Condensing of Low-Density Fat by Mechanical Process Improves Fat Retention and Reduces Oil Cyst Formation in Breast Reconstruction

BACKGROUND

Although autologous fat grafting is a useful adjunct for breast reconstruction, its indications remain limited as large-volume fat grafting results in high absorption and complication rates. Low-density fat includes small numbers of viable cells and considerable oil, resulting in nodules and oil cysts. This study evaluated the volumization effect and complications with combined fat grafting of condense low-density fat and high-density fat.

METHODS

This retrospective, single-center study included 25 patients who underwent combined grafting of condensed low-density fat and high-density fat (CLDF + HDF) and 20 patients who underwent conventional Coleman fat grafting for breast reconstruction from December 2017 to January 2022. Retention rates and complications were evaluated by magnetic resonance imaging and ultrasound rates. Patient satisfaction was evaluated using a typical Likert scale. Photographs were taken and imageological examinations were performed before and after treatment.

OUTCOMES

Graft retention rate was higher in patients who underwent CLDF + HDF than Coleman fat grafting for breast reconstruction (38.40 ± 4.41% vs. 31.43 ± 5.43%, p <0.05). One patient in the CLDF + HDF grafting group, compared with twelve in the Coleman fat grafting group, developed oil cysts exceeding 1 cm. Patient satisfaction rate was higher in the CLDF + HDF grafting group.

CONCLUSIONS

Mechanical processes can concentrate the cellular content of LDF and remove oil, condensing LDF to the level of HDF. Combined grafting of CLDF optimized by mechanical processing and HDF is effective for breast reconstruction, with a higher retention rate and a lower incidence of complications than conventional Coleman fat grafting.

Evaluating the Necessity of Capsulectomy in Cases of Textured Breast Implant Replacement

BACKGROUND

Capsulectomy has traditionally been recommended as a treatment for capsular contracture after breast augmentation. With the advent of breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL), and the Food and Drug Administration's decision to ban Biocell textured devices, this operation has taken on new importance. This review was undertaken to better inform clinical recommendations for women with textured devices.

METHODS

An electronic search was performed using PubMed to identify all the available literature on the subject of capsulectomy and open capsulotomy (the alternative treatment).

RESULTS

Fifty-seven articles on this topic were identified. Capsulectomy was widely recommended for treatment of capsular contracture, although many authors recommended leaving thin capsular tissue behind in the absence of symptoms. En bloc resection was recommended only for women with a diagnosis of BIA-ALCL. No information supported a prophylactic role for capsulectomy in asymptomatic women with textured breast implants who are concerned regarding their future risk of BIA-ALCL. Routine pathologic examination in asymptomatic patients was not supported.

DISCUSSION

Capsulectomy adds substantially to the surgical risk, discomfort, recovery time, and expense. Implant removal or replacement without a simultaneous capsulectomy is atraumatic and poses negligible risk.

CONCLUSIONS

Capsulectomy introduces additional morbidity and is not mandatory for asymptomatic patients. Implant removal or exchange for smooth implants without a capsulectomy may be an acceptable choice for many women who do not demonstrate capsular pathology. However, any symptoms or surgical findings suggesting pathology warrant a capsulectomy. En bloc resections are reserved for patients diagnosed with BIA-ALCL.

Prospective Study of Saline versus Silicone Gel Implants for Subpectoral Breast Augmentation

Background

Silicone gel implants are regarded as esthetically superior to saline implants, offering a more natural consistency. They are also considered less susceptible to rippling. However, objective measurements and patient-reported outcome studies are lacking. Similarly, minimal data are available quantitating animation deformity.

Methods

A 3-year prospective study was undertaken among 223 women undergoing primary subpectoral breast augmentation using either saline (n = 145) or silicone gel (n = 78) implants. Photographs obtained included frontal views with the patient flexing the pectoral muscles. Images were matched, and vertical differences in nipple position were measured. Breast implants were evaluated using high-resolution ultrasound to detect any ripples or folds at least 3 months after surgery. Outcome surveys were administered. Statistical analysis included the χ² test, point-biserial correlations, and a power analysis.

Results

Respondents reported visible rippling in 18% of women and palpable rippling in 32% of patients, with no significant difference between women treated with saline and silicone gel implants. Ripples were detected on ultrasound scans in 24% of women with saline implants and in 27% of women with silicone gel implants (difference not significant). Ripples were more common in women with lower body mass indices. Fifty percent of patients demonstrated nipple displacement <1 cm on animation. Nipple displacement occurred either up or down with equal frequency and a mean overall nipple displacement of zero.

Conclusions

Saline and silicone breast implants produce similar degrees of rippling, as determined on outcome surveys and ultrasound examination. Animation deformities tend to be minor and well-tolerated.

Inadvertent Rupture of a Silicone Breast Implant during Fat Grafting: Surgical and Radiological Findings

Autologous fat grafting is a common, relatively safe procedure for breast augmentation and reconstruction. The most commonly reported complications tend to be fat necrosis and oil cysts. The incidence of rare events, such as breast implant rupture, is likely underreported. Here we present the case of a patient who underwent fat grafting and sustained implant rupture with injection of fat within the silicone implant. She complained of her implant changing shape and magnetic resonance imaging (MRI) showed classic signs of implant rupture (linguini sign). At the time of surgery however, fat was surprisingly found to be within the implant itself. To our knowledge this finding has yet to be reported. Here we review the radiologic and surgical findings of implant rupture following fat grafting and present some suggestions to prevent this occurrence and ensure safe, aesthetically pleasing outcomes.
