Long-Term Outcomes after Primary Breast Reconstruction Using a Vertical Skin Pattern for Skin-Sparing Mastectomy:

Wise Versus Vertical Mastopexy Pattern Skin-reducing Mastectomy With Immediate Breast Reconstruction: Systematic Review and Meta-analysis

Background

This study compares postoperative outcomes of Wise and vertical mastopexy pattern skin-reducing/skin-sparing masctomy, hypothesizing that incision choice affects cosmetic outcomes and complication rates.

Methods

A systematic review and meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searching PubMed, MEDLINE, Embase, Web of Science, and StarPlus Library. Included studies documented skin-sparing mastectomy using Wise or vertical mastopexy patterns with immediate reconstruction. The primary outcome is total mastectomy flap necrosis. The secondary outcomes are major/minor necrosis, infection, hematoma, seroma, and wound complications. Bayesian and frequentist generalized linear mixed models were used for the meta-analysis, including studies with 0 events.

Results

Sixty-six studies were identified, with 39 included in the meta-analysis, comprising 1954 patients and 2311 breast reconstruction cases. The Wise group had a higher rate of mastectomy flap necrosis (14.2%; 95% confidence interval: 10%-20%; I² = 83%) compared with the vertical group (7.8%; 95% confidence interval: 5%-12%; I² = 0%) (P < 0.05). No significant differences were found in other domains. Subgroup analysis favored vertical mastopexy for wound-related complications (P = 0.04).

Conclusions

The Wise pattern shows significantly higher mastectomy flap necrosis than the vertical pattern. However, there were no significant differences in major necrosis, minor necrosis, infection, hematoma, or seroma. Future studies should focus on larger, high-quality randomized controlled trials to better understand the impact of incision techniques on postoperative outcomes.

Head-to-Head Analysis of Vertical vs Horizontal Incision Patterns in Breast Reconstruction: Surgical Outcomes and Aesthetic Implications

BACKGROUND

Modern aesthetically optimized breast reconstruction requires collaboration between the patient, breast surgeon, and plastic surgeon. To optimize both surgical outcome and aesthetic results, incision patterns must be carefully planned.

OBJECTIVES

We aimed to determine whether vertical or horizontal orientation of mastectomy incision was preferred in the general population and to analyze corresponding complication profiles.

METHODS

A retrospective review was performed of all patients undergoing bilateral mastectomy followed by autologous breast reconstruction utilizing either vertical or horizontal incision from January 2011 to November 2022. Postoperative complications of the 2 incision patterns were analyzed. Additionally, crowdsourcing was utilized to assess aesthetic implications of horizontal and vertical incision patterns on postoperative pictures of completed breast reconstruction. Survey rater demographics were also analyzed to assess differences in scoring based on voter characteristics.

RESULTS

There were no significant differences in postoperative breast complications between patients with horizontal or vertical incisions when considering wound, infection, seroma, hematoma, fat necrosis, or overall complications (P > .05). Crowdsourcing showed that, regardless of voter demographics, vertical incisions were preferred over horizontal incisions (P < .001). Additionally, voters who knew someone who had undergone breast reconstruction were more likely to rate all incision patterns higher than other voters (P < .001).

CONCLUSIONS

Although there are no significant differences in complication profiles between vertical and horizontal incisions in autologous breast reconstruction patients, vertical incision patterns are preferred aesthetically by the general population.

Abdominal-Based Microsurgical Breast Reconstruction: How to Inset the Flap to Maximize the Aesthetic Result-A Systematic Review

Nowadays, the ultimate goal of microsurgical breast reconstruction is not merely the effective transfer of vascularized tissue but the achievement of a natural, symmetric appearance. The aim of this present study was to systematically summarize the published evidence on abdominal-based free flap inset for breast reconstruction in order to provide principles and classification that could guide the surgeon in choosing the most appropriate inset technique based on patient and flap characteristics. A comprehensive review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, looking for articles on the insetting technique for free flap breast reconstruction. After screening 306 publications, 24 papers (published from 1994 to 2020) were included in the study. We identified four main breast anatomical features on which the papers reviewed focused when describing their insetting technique: breast width, breast ptosis, breast projection, and upper pole fullness. Patient body type, type of mastectomy, and reported complications are also discussed. Flap shaping and inset during breast reconstruction are fundamental steps in any reconstructive procedure. Despite the low evidence in the current literature, this systematic review provides a framework to guide the surgeon's decision-making and optimize the aesthetic outcomes of abdominal-based free flap breast reconstruction.

The Impact of Diabetes Mellitus on Breast Reconstruction Outcomes and Complications: A Systematic Literature Review and Meta-analysis

INTRODUCTION

As the incidence of breast cancer and diabetes rises, so does the number of patients with diabetes undergoing breast reconstruction (BR). Patients with diabetes are at a higher risk for post-operative complications. The current study examined the effects of diabetes on BR wound outcomes and overall complications post-operatively.

METHODS

This study followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. We conducted a systematic search and meta-analysis for published articles on the effects of DM on BR in January 2022 using the PubMed, MEDLINE, and Cochrane databases. Diabetes, breast reconstruction, and complications were used as keywords.

RESULTS

Forty-three studies were included in the qualitative synthesis, and five provided data to be included in the meta-analysis published between 2006 and 2020. A total of 19,731 patients (9.07%) had diabetes, whereas 197,812 patients had no diabetes. The results of the pooled outcomes revealed no differences in the risk of total flap loss (p = 0.892) and wound infection (p = 0.579,). Nevertheless, the risk of wound dehiscence was significantly higher among patients with diabetes than their non-diabetic counterparts (p < 0.0001).

CONCLUSION

Diabetic patients undergoing BR have a significantly higher risk of wound dehiscence. As a result of the adverse effects of diabetes status on BR outcomes, patients need to be counseled about optimizing their diabetes management before surgery. Because of the heterogeneity in our results, prospective randomized studies are needed to shed light on the consequences of diabetes mellitus in BR surgeries.

Breast cancer recurrence after immediate and delayed postmastectomy breast reconstruction-A systematic review and meta-analysis

BACKGROUND

Oncological safety of different types and timings of PMBR after breast cancer remains controversial. Lack of stratified risk assessment in literature makes current clinical and shared decision-making complex. This is the first systematic review and meta-analysis to evaluate differences in oncological outcomes after immediate versus delayed postmastectomy breast reconstruction (PMBR) for autologous and implant-based PMBR separately.

METHODS

A systematic literature search was performed in MEDLINE, Cochrane Library, and Embase. The Cochrane Collaboration Handbook and Meta-analysis Of Observational Studies in Epidemiology checklist were followed for data abstraction. Variability in point estimates attributable to heterogeneity was assessed using I2 -statistic. (Loco)regional breast cancer recurrence rates, distant metastasis rates, and overall breast cancer recurrence rates were pooled in generalized linear mixed models using random effects.

RESULTS

Fifty-five studies, evaluating 14,217 patients, were included. When comparing immediate versus delayed autologous PMBR, weighted average proportions were: 0.03 (95% confidence interval [CI], 0.02-0.03) versus 0.02 (95% CI, 0.01-0.04), respectively, for local recurrences, 0.02 (95% CI, 0.01-0.03) versus 0.02 (95% CI, 0.01-0.03) for regional recurrences, and 0.04 (95% CI, 0.03-0.06) versus 0.01 (95% CI, 0.00-0.03) for locoregional recurrences. No statistically significant differences in weighted average proportions for local, regional and locoregional recurrence rates were observed between immediate and delayed autologous PMBR. Data did not allow comparing weighted average proportions of distant metastases and total breast cancer recurrences after autologous PMBR, and of all outcome measures after implant-based PMBR.

CONCLUSIONS

Delayed autologous PMBR leads to similar (loco)regional breast cancer recurrence rates compared to immediate autologous PMBR. This study highlights the paucity of strong evidence on breast cancer recurrence after specific types and timings of PMBR.

LAY SUMMERY

Oncologic safety of different types and timings of postmastectomy breast reconstruction (PMBR) remains controversial. Lack of stratified risk assessment in literature makes clinical and shared decision-making complex. This meta-analysis showed that delayed autologous PMBR leads to similar (loco)regional recurrence rates as immediate autologous PMBR. Data did not allow comparing weighted average proportions of distant metastases and total breast cancer recurrence after autologous PMBR, and of all outcome measures after implant-based PMBR. Based on current evidence, oncological concerns do not seem a valid reason to withhold patients from certain reconstructive timings or techniques, and patients should equally be offered all reconstructive options they technically qualify for.

Immediate Reconstruction of Large Ptotic Breasts following Vertical Reduction Pattern Nipple-Sparing Mastectomy

Purpose

Women with large and/or ptotic breasts are generally not considered candidates for nipple-sparing mastectomy because of concerns regarding the high incidence of postoperative complications including ischemic complications. Therefore, we adopted a vertical skin resection technique for nipple-sparing mastectomy, and obtained satisfactory results following immediate autologous breast reconstruction. In this study, we aimed to describe our operative technique and review its outcomes.

Methods

Between January 2010 and March 2017, immediate autologous breast reconstructions were performed in 28 patients with moderate or large ptotic breasts after nipple-sparing mastectomy using the vertical reduction pattern. Grade II ptosis was observed in 12 patients, and 16 patients were classified as having grade III ptosis.

Results

Of the 28 patients, 21 received abdominal free flap reconstruction. In the remaining 7 patients, extended latissimus dorsi flaps were used in conjunction with anatomic implants. The mean weight of the excised breast tissue in the 2 groups was 575 g and 482 g, respectively. Satisfactory esthetic outcomes without major complications were achieved in all patients. Similar vertical reductions or mastopexies in the contralateral breast allowed better postoperative adjustment for symmetry. There was only 1 case of complete nipple necrosis; however, the problem was solved with “skin banking.” No local recurrences or distant metastases were detected at follow-up (mean 18 months, range 4 months to 6 years).

Conclusion

To enhance cosmetic outcomes in patients with large and/or ptotic breasts, the vertical skin resection pattern for nipple-sparing mastectomy can be used to achieve better breast shape while preserving the nipple-areola complex. Moreover, it can improve the esthetic outcome without compromising oncologic safety.

Mastectomy Incision Design to Optimize Aesthetic Outcomes in Breast Reconstruction

Background:

Choosing the optimal mastectomy incision must account for oncologic, reconstructive, and aesthetic considerations, including nipple preservation, mastectomy skin margins and potential for skin involvement, mastectomy skin perfusion and viability, mastectomy skin excess, previous breast scars, the reconstructive plan, and inconspicuous new scar placement. In the present study, we aimed to assess breast reconstruction aesthetics, as they are influenced by mastectomy incision design.

Methods:

Nine commonly utilized mastectomy incision patterns were grouped into 3 categories: hidden scar, vertical scar, and transverse scar. Twenty plastic surgeons were asked to blindly grade before and after photographs of reconstructed breasts with regard to scar visibility and position and according to their influence on breast aesthetics.

Results:

Statistically significant differences were observed between the study groups. Mastectomies and reconstructions performed through hidden incisions yield the most aesthetic results. Vertical scars are favorable to transverse scars. In the case of bilateral reconstructions, symmetric scar placement is paramount to optimizing aesthetic outcomes.

Conclusions:

The mastectomy incision pattern significantly affects the aesthetic outcomes in breast reconstruction. Patterns borrowed from cosmetic breast surgery consistently yield highly aesthetic outcomes. Surgeons must consider oncologic factors and patient characteristics in choosing an ideal incision for each patient.

Analysis of the vertical mammaplasty design in skin-sparing mastectomy and immediate autologous reconstruction

BACKGROUND

Skin-sparing mastectomy designs for immediate autologous breast reconstruction include racquet, Wise, and vertical mammaplasty incisions. The vertical design addresses ptosis while maintaining viable skin flaps. This study compares the racquet to the vertical incision.

METHODS

Immediate skin-sparing autologous breast reconstructions by a single surgeon using either vertical or racquet incisions from August 2006 to September 2011 were analyzed. Aesthetic scoring was based on a Likert-scale assessment of scar appearance, shape, preoperative versus postoperative aesthetic comparison, and overall aesthetic outcome. Responses were analyzed using the Mann-Whitney test.

RESULTS

Seventy-seven patients (48 racquets and 29 vertical) were included. Patient demographics and complications did not differ. Vertical design reconstructions were used for patients with higher-grade ptosis (p < 0.001). Significantly better-appearing scars (3.8 vs. 3.5; p = 0.04) were observed in the vertical group. Vertical reconstructions showed a trend toward significance in cosmetic improvement compared with preoperative appearance (3.2 vs. 3.0; p = 0.06). There was no difference in shape (vertical 3.6, racquet 3.6; p = 0.86) or in postoperative aesthetic result (vertical 3.6, racquet 3.4; p = 0.41).

CONCLUSIONS

Shape and overall postoperative aesthetic appearance did not significantly differ despite greater ptosis preoperatively in the vertical group, demonstrating the efficacy of the vertical design in reconstruction. Vertical design reconstructions were rated aesthetically superior to their pre-mastectomy appearance. Significantly better scar scores in the vertical group reflect the camouflaged nature of vertical incisions. These results demonstrate that the aesthetic outcome of the vertical design reconstruction in ptotic breasts is as good as and potentially superior to the racquet design reconstruction in non-ptotic breasts.

Management of the ptotic or hypertrophic breast in immediate autologous breast reconstruction: a comparison between the wise and vertical reduction patterns for mastectomy

BACKGROUND

The Wise pattern can be used in mastectomies to address the excess skin in the ptotic or hypertrophic breast; however, limitations include mastectomy flap necrosis (MFN) and poor shape. The vertical pattern can potentially reduce the amount of MFN with improved aesthetic results. This study compares the Wise and vertical mastectomy patterns in immediate, autologous breast reconstruction.

METHODS

Thirty-three patients with grade 2 or 3 ptosis who elected to undergo immediate, autologous breast reconstruction were prospectively recruited into 2 nonrandomized cohorts. Of total, 17 patients (26 reconstructions) had Wise pattern and 16 (28 reconstructions) had vertical pattern. All patients were followed for MFN, time for wound healing, and postoperative complications. Patient and surgeon surveys rated the aesthetics of the reconstructions.

RESULTS

The 2 groups did not differ in age, body mass index, smoking, or breast measurements. The Wise group had significantly larger areas of MFN, higher number of postoperative visits, and longer wound-healing periods, compared with the vertical group (P < 0.05). There was no difference in time to adjuvant therapy or additional procedures. Patient surveys rated both incisions with equal satisfaction, except for symmetry that rated better in the Wise group. Surgeon surveys showed better scores for the vertical incision.

CONCLUSIONS

The Wise pattern is associated with significantly more MFN and prolonged wound care. Despite this complication, patients rate their breast reconstructions favorably, regardless of the type of incision. Both the Wise and vertical patterns can be safely used in skin-sparing mastectomies with immediate, autologous breast reconstruction with good aesthetic outcomes. The authors recommend the vertical pattern because of less MFN and surgeon-preferred aesthetics.

Nipple reconstruction with banked costal cartilage after vertical-type skin-sparing mastectomy and deep inferior epigastric artery perforator flap

We recently used skin-sparing mastectomy (SSM), the deep inferior epigastric artery perforator (DIEP) flap, and delayed nipple reconstruction with banked costal cartilage. Eight patients who underwent these reconstructions between 2008 and 2010 were reviewed. SSM was performed by vertical-type incision. We transferred the DIEP flap using an internal thoracic vessel and banked costal cartilage into an abdominal wound. Three to 6 months later, we removed the cartilage and cut it into a cylindrical shape. We fixed the cartilage on the dermal base of a modified C-V flap. No flap necrosis or exposure of cartilage was seen and the scar was acceptable in all cases. At a mean follow-up of 12.6 months, 59% of the nipple projection was maintained in comparison to immediately postoperatively. Our new concept is the combination of SSM, DIEP, and banked cartilage, and furthermore putting the cartilage on a dermal base. With support from the dermis, a large, complicated cartilage form is unnecessary.

Staged wise-pattern skin excision for reconstruction of the large and ptotic breast

BACKGROUND

The postmastectomy reconstruction of large and/or ptotic breasts poses a more difficult aesthetic challenge than the reconstruction of small or moderately sized breasts because of an excessively large skin envelope in both horizontal and vertical dimensions. The Wise-pattern skin excision best addresses this excess skin but is associated with a high incidence of tissue necrosis with subsequent wound breakdown, primarily at the T point. To optimize the aesthetic potential and minimize complications in the setting of these large skin envelopes, the authors have deconstructed the single-stage Wise-pattern skin excision into a two-stage procedure, eliminating the need for a primary simultaneous T-point closure.

METHODS

In the first stage, the mastectomy and reconstruction are performed using a vertical excision, which tightens the breast skin envelope horizontally. In the second stage, the redundant skin at the inframammary fold is excised horizontally, tightening the breast skin envelope vertically. The summation of the two staged excisions recreates the Wise pattern, breaking up the T point into two straightforward primary closures.

RESULTS

Twelve patients (21 breasts) underwent successful reconstruction using the staged Wise-pattern skin excision. The breast size, shape, and projection of the patients were greatly improved without any wound complications.

CONCLUSIONS

The staged Wise-pattern skin excision for breast reconstruction is a simple technique that delivers superior results for the challenging reconstruction of large and/or ptotic breasts. This method offers an aesthetically pleasing breast shape, allows for the correction of ptosis, eliminates wound complications, and results in a standard Wise-pattern scar.

Recent advances in the surgical care of breast cancer patients

A tremendous improvement in every aspect of breast cancer management has occurred in the last two decades. Surgeons, once solely interested in the extipartion of the primary tumor, are now faced with the need to incorporate a great deal of information, and to manage increasingly complex tasks.

As a comprehensive assessment of all aspects of breast cancer care is beyond the scope of the present paper, the current review will point out some of these innovations, evidence some controversies, and stress the need for the surgeon to specialize in the various aspects of treatment and to be integrated into the multisciplinary breast unit team.
