Pioneering technique using Acellular Dermal Matrix in the rescue of a radiation ulcer

BACKGROUND

Radiotherapy as an adjuvant to mastectomy is integral to the treatment of breast cancer, but can result in skin ulceration. Skin ulceration following radiotherapy is traditionally managed by removing the implant and allowing the skin to heal by secondary intention.

CASE REPORT

A 42-year-old woman underwent radiotherapy following a breast reconstruction. She developed a 2 x 3cm radiation ulcer. The ulcer was managed by removing the implant and performing capsulectomy. A Beckers 50 expander was placed and reinforced with acellular dermal matrix inferolaterally. At follow-up the patient had a good cosmetic outcome.

CONCLUSION

Post-radiation skin ulcers present a challenge to treat with no current standardised management. The use of acellular dermal matrix may present a new technique to promote healing in these testing cases.

The Laminated Nature of the Pectoralis Major Muscle and the Redefinition of the Inframammary Fold: Clinical Implications in Aesthetic and Reconstructive Breast Surgery

The breast is appreciated aesthetically and clinically for its shape, projection, and volume. Surgical techniques have evolved to manipulate the breast skin envelope, soft tissues, and chest wall anatomy, with and without prosthetic devices. The pectoralis major specifically is altered for pocket dissection and implant coverage. Both the aesthetic and reconstructive surgeons are aware of its relationship to the chest wall and the breast soft tissues. Both are able to achieve outstanding outcomes; however, the authors present an alternative appreciation of the pectoralis and its relationship to the breast.

Preoperative Saline Implant Deflation in Revisional Aesthetic Breast Surgery

BACKGROUND

Preoperative saline deflation is a clinically useful intervention in revisional breast surgery. It allows suspensory ligament recovery, reveals true glandular volume, and simplifies mastopexy markings. Presently unknown are the volumetric changes that occur after deflation.

OBJECTIVES

The authors report the three-dimensional (3D) changes that occur with preoperative deflation prior to revisional breast surgery.

METHODS

We reviewed available charts of revisional breast surgery patients who underwent preliminary saline implant deflation. Our protocol is deflation 4 weeks prior to revision. Three weeks following deflation, the patient is evaluated to finalize the operative plan, including the need for implants, mastopexy, and adjunctive procedures. A subset underwent 3D imaging to quantify the volumetric changes over the 3-week deflation period.

RESULTS

Between 2002 and 2014, 55 patients underwent saline implant deflation prior to 57 revisional surgeries. Seventeen were revised without implants and 40 with implants. The 3D subset of 10 patients showed a mean 15.2% volume increase and 0.18 cm notch-to-nipple distance decrease over the 3 weeks following deflation and prior to definitive surgical correction.

CONCLUSIONS

Breast volume increases and the notch-to-nipple distance decreases during the 3-week interval prior to reoperation. This "elastic breast recoil" occurs after the mass effect of the implant is removed, resulting in recovery of stretched suspensory ligaments and gland reexpansion. We believe 4 weeks is optimal for gland normalization. Ideal candidates include patients requiring secondary mastopexy without implants, implant downsizing in the same pocket, and secondary augmentation mastopexy. Preoperative saline deflation and 3D analyses are useful for preoperative planning in reoperative breast surgery.

Augmentation Mammaplasty After Breast Enhancement With Hyaluronic Acid

BACKGROUND

Macrolane is a stabilized, hyaluronic acid-based gel that has been available since 2007 as a minimally invasive, nonpermanent option for breast enhancement. However, numerous controversies pertaining to its side effects have highlighted the need for studies involving larger groups of patients.

OBJECTIVES

The authors sought to determine complications of Macrolane injections for breast enhancement and performed surgical evacuation of cysts comprising collections of hyaluronic acid in patients who previously received Macrolane treatment and presented for augmentation mammaplasty.

METHODS

The authors reviewed a case series of 20 patients who were treated elsewhere with intramammary injection of Macrolane for cosmetic purposes and who presented at the authors' medical studio with multiple intramammary and intramuscular cysts. All patients underwent surgical evacuation of the hyaluronic acid-based cysts in association with augmentation mammaplasty.

RESULTS

Good aesthetic results were achieved in all patients. Three months after surgery, 15 of 20 (75%) patients rated themselves as very much improved; 4 patients (20%) rated themselves as moderately improved, and 1 patient (5%) rated herself as somewhat improved.

CONCLUSIONS

The authors suggest that Macrolane cannot be considered a valid alternative for breast augmentation at this time.

Shaping of the Unaffected Breast with Brava-Assisted Autologous Fat Grafting to Obtain Symmetry after Breast Reconstruction

BACKGROUND

In breast reconstruction, symmetry is a vital issue. However, when the original breast is unusually shaped or the patient desires augmentation at the time of reconstruction, obtaining symmetrical breasts becomes difficult.

OBJECTIVES

The authors performed shaping of unaffected breasts by Brava-assisted autologous fat grafting to enhance breast symmetry, and evaluated the clinical results to validate this new approach.

METHODS

Brava-assisted autologous fat grafting was performed to the unaffected breasts of 12 patients who had undergone unilateral breast reconstruction. The procedure was used for augmentation in six patients and to correct ptosis, volume, and tuberous breast deformity in three, two, and one patient, respectively. Clinical outcomes were assessed in all 12 patients.

RESULTS

All patients could complete fat grafting within two sessions (one session in nine patients and two sessions in three patients). The mean volume of grafted fat per session was 211 cc in all patients. The mean retention rate of grafted fat was 58.9% in the 10 patients for whom the retention rate could be calculated using preoperative and postoperative magnetic resonance imaging (MRI). Postoperative MRI revealed small benign foci in two patients (16.7%), which were not palpable and did not become a clinical problem. A postoperative mammography revealed a small agglutinate calcification in one patient, which was determined to be benign through biopsy.

CONCLUSIONS

Shaping the unaffected breast by autologous fat grafting combined with Brava is predictable, effective, and feasible as an aesthetic adjunct to unilateral breast reconstruction to achieve breast symmetry.

Sientra primary and revision augmentation rupture trending and analysis with magnetic resonance imaging

BACKGROUND

Rupture of silicone gel breast implants is a rare occurrence but remains one of the key surgical concerns. The objective of this article was to provide visibility and information on trends for the impact that patient and surgical characteristics play in the occurrence of rupture.

OBJECTIVES

Examine trends in surgical techniques to better understand the etiology of implant rupture.

METHODS

Analysis was based on Sientra's prospective, open-label, U.S.-based clinical study of High-Strength Cohesive silicone breast implants. Patient and surgical characteristics were compared between ruptured and intact implants.

RESULTS

The subset of data used for this analysis included 1792 implants in 935 primary and revision augmentation patients implanted by 31 plastic surgeons, with an average follow-up of 6.6 years. The results confirm that rupture remains a rare adverse event. Overall, the rupture prevalence for this study was 2.4%. Rupture prevalence was lower among textured devices (0.8%) compared to smooth devices (3.8%). The prevalence of rupture was 7.8% among devices placed with a transaxillary incision site compared to 1.6% and 3.0% when placed with an inframammary or periareolar incision site, respectively. Rupture was reported in 5.5% of the devices that received steroid pocket irrigation, compared to 1.8% of the devices that did not.

CONCLUSIONS

Although ruptures in the Sientra study with the High-Strength Cohesive silicone gel implants were an uncommon occurrence, the authors were able to identify strong trends for the association of certain surgical factors and characteristics. The results show among other factors that an inframammary approach and a textured device were found to be protective against rupture.

Eight-year follow-up data from the U.S. clinical trial for Sientra's FDA-approved round and shaped implants with high-strength cohesive silicone gel

BACKGROUND

On March 9, 2012, the Food and Drug Administration (FDA) approved Sientra's premarket approval application for its portfolio of silicone gel breast implants based on their review of Sientra's 3-year study data from the largest pivotal silicone gel breast implant study to date. This included the first approval of shaped breast implants in the United States.

OBJECTIVES

The authors provide an update to the 8-year safety and effectiveness of the Sientra High-Strength silicone gel breast implants.

METHODS

The Sientra Core study is an ongoing 10 year open-label, prospective, multi-center clinical study, which includes 1788 patients implanted with 3506 Sientra implants across four indications (Primary Augmentation, Revision Augmentation, Primary Reconstruction, and Revision Reconstruction). For the safety analysis, the incidence of post-operative complications, including all breast implant-related adverse effects (eg, infection, asymmetry), was estimated based on Kaplan-Meier risk rates. The effectiveness analyses include surgeon and patient satisfaction and changes in bra/cup size.

RESULTS

Through 8 years, the overall risk of rupture was 4.6%, the risk of capsular contracture was 11.8% (rates were lower when using True Texture™), and the risk of reoperation was 28.3%. Out of the 580 reoperations in 456 patients, over half of all reoperations were due to cosmetic reasons (n = 299). The most common reasons for reoperation were capsular contracture (19.0%), style and/or size change (18.4%), and asymmetry (8.8%). Patient satisfaction remains high through 8 years, with 87% indicating that their breast implants make them feel more feminine than prior to enrollment.

CONCLUSIONS

Safety data from the FDA Core study continues to support a comprehensive safety and effectiveness profile of Sientra's portfolio of round and shaped implants through 8 years.

Does immediate tissue expander placement increase immediate postoperative complications in patients with breast cancer?

The objectives of this study were to evaluate 1) the rate of immediate breast reconstruction; 2) the frequency of immediate tissue expander placement; and 3) to compare perioperative outcomes in patients who underwent breast reconstruction after mastectomy for breast cancer with immediate tissue expander placement (TE) with those with no reconstruction (NR). Using the Nationwide Inpatient Sample database, we examined the clinical data of patients with breast cancer who underwent mastectomy with or without immediate TE from 2006 to 2010 in the United States. A total of 344,253 patients with breast cancer underwent mastectomy in this period in the United States. Of these patients, 31 per cent had immediate breast reconstruction. We only included patients with mastectomy and no reconstruction (NR: 237,825 patients) and patients who underwent only TE placement with no other reconstruction combination (TE: 61,178 patients) to this study. Patients in the TE group had a lower overall postoperative complication rate (2.6 vs 5.5%; P < 0.01) and lower in-hospital mortality rate (0.01 vs 0.09%; P < 0.01) compared with the NR group. Fifty-three per cent of patients in the NR group were discharged the day of surgery compared with 36 per cent of patients in the TE group. Using multivariate regression analyses and adjusting patient characteristics and comorbidities, patients in the TE group had a significantly lower overall complication rate (adjusted odds ratio [AOR], 0.6) and lower in-hospital mortality (AOR, 0.2) compared with the NR group. The rate of immediate reconstruction is 31 per cent. TE alone is the most common type of immediate reconstruction (57%). There is a lower complication rate for the patients who underwent immediate TE versus the no-reconstruction cohort.

[Management of breast cancer in a woman with breast implants]

The incidence of breast cancer, currently one woman on eight, also concerns patients who underwent augmentation surgery. Breast implants have already been the subject of numerous publications concerning the risk of inducing breast cancer or of delaying its diagnosis; however, no significant causal relationship has been established. The purpose of this article is to assess the diagnostic and therapeutic consequences when breast cancer is identified in a patient with breast implants.

['Which breast implant do I have?'; the importance of the Dutch Breast Implant Registry]

About 1 in 300 women in the Netherlands has a breast implant but many patients do not know what type of implant was inserted. The quality of breast implants is currently monitored by the implant manufacturers. Sufficient incidents have occurred to show that an independent registry is required to measure the quality of breast implants and to facilitate a national recall, if necessary. Good national and international collaboration with the government, the manufacturers and other specialist associations is crucial for setting up an implant registry. Since April 2015, data about patients and their implants have been collected, independently and prospectively, in the Dutch Breast Implant Registry to increase patient safety in cases of breast implant surgery in the Netherlands.

Anatomy of the sternal origin of the pectoralis major: implications for subpectoral augmentation

BACKGROUND

The pectoralis major typically is manipulated for implant coverage and pocket design in subpectoral breast augmentation. An understanding of its anatomy can guide successful creation of the implant pocket.

OBJECTIVES

The authors evaluated the anatomy of the sternal origin of the pectoralis major to inform surgical planning, help establish a technique for subpectoral augmentation mammaplasty, and identify the most common locations of perforators.

METHODS

The sternal origins of 24 pectoralis major muscles were dissected and examined in 15 female cadavers to determine the structure and width of the pectoralis major sternal origin and its relationship to the locations of internal mammary perforators.

RESULTS

The average width of the sternal origin of the pectoralis major was 7.1 mm (range, 3 mm-1.8 cm). This width decreased slightly from the second rib to the second intercostal space and then increased progressively in the caudal direction toward the fifth rib. The sternal origin terminated an average of 5.4 mm (range, 1-16 mm) from the midline, with the greatest distance at the fifth rib and large variability throughout. A row of perforators from the internal mammary artery traversed the subpectoral space an average of 2.7 cm from the midline (range, 1-3.7 cm).

CONCLUSIONS

The sternal origin of the pectoralis major was thin and highly variable, suggesting that its partial release for implant medialization during subpectoral augmentation is unsafe.

Prevalence of Body Dysmorphic Disorder Among Patients Seeking Breast Reconstruction

BACKGROUND

Body dysmorphic disorder (BDD) is characterized by a preoccupation with a slight or imagined defect in physical appearance. It has significant implications for patients who desire breast reconstruction, because patient satisfaction with the aesthetic outcome is a substantial contributor to the success of the procedure.

OBJECTIVES

The authors estimated the prevalence of BDD among women seeking breast reconstruction by surveying patients with the previously validated Dysmorphic Concerns Questionnaire (DCQ).

METHODS

One hundred eighty-eight women who presented for immediate or delayed breast reconstruction completed the DCQ anonymously, during initial consultation with a plastic surgeon. Two groups of respondents were identified: those who desired immediate reconstruction and those who planned to undergo delayed reconstruction. The prevalence of BDD among breast reconstruction patients was compared between the 2 groups, and the overall prevalence was compared with published rates for the general public.

RESULTS

Body dysmorphic disorder was significantly more prevalent in breast reconstruction patients than in the general population (17% vs 2%; P < .001). It also was much more common among patients who planned to undergo delayed (vs immediate) reconstruction (34% vs 13%; P = .004).

CONCLUSIONS

Relative to the general public, significantly more women who sought breast reconstruction were diagnosed as having BDD. Awareness of the potential for BDD will enable clinicians to better understand their patients' perspectives and discuss realistic expectations at the initial consultation. Future studies are warranted to examine the implications of BDD on patient satisfaction with reconstructive surgery.

Capsular grafts and flaps in immediate prosthetic breast reconstruction

BACKGROUND

Patients with previously augmented breasts and a diagnosis of breast cancer who are candidates for immediate prosthetic reconstruction can benefit from capsular tissues used for splinting the position of the pectoralis major muscle.

METHODS

A retrospective clinical review of patients with previously augmented breasts who are undergoing mastectomy and immediate prosthetic reconstruction with capsular tissues was undertaken. The bottom of the periprosthetic capsule was tailored in a novel and versatile fashion as grafts or flaps and used as a sling between the pectoralis major and the inframammary fold.

RESULTS

Of the 21 patients in this study, 19 had unilateral reconstruction, whereas 2 had bilateral reconstructions. Capsular tissues were harvested as free capsular grafts in 15 cases and raised as a capsular flap in the remaining 8 cases. During the follow-up period, complications were detected in 7 patients (1 seroma, 1 infection, 1 hematoma, 1 superficial epidermolysis, 2 cases of rippling, and 1 mild capsular contracture).

CONCLUSIONS

For eligible patients, the use of capsular tissues offers a readily available and cost-effective alternative to acellular dermal matrices with a negligible complication rate. Patient selection is key to ensuring a safe oncologic approach and must be carefully carried out in close collaboration with the breast surgeon.

Pure pectus carinatum (not associated with pectus excavatum) solved by MIRPC (minimally invasive repair of pectus carinatum) associated with bilateral mamarian hypoplasia solved by bilateral breast implants

We present the case of a young 24-year-old woman with an important but symmetrical pectus carinatum, not associated with pectus excavatum, without cardiorespiratory symptoms but with significant psychosocial implications for the patient, solved by the minimally invasive technique described by Abramson(reversed Nuss procedure) - MIRPC (Minimally invasive Repair of Pectus carinatum). The sternal malformation was associated with bilateral mammary hypoplasia, solved by bilateral breast implants 10 months later. The evolution was favorable and the aesthetic result was satisfactory for the patient.
