Inframammary Fold Reconstruction in the Previously Reconstructed Breast: A Comprehensive Review

Clinical outcomes and aesthetic results of reverse sequence endoscopic versus traditional bilateral nipple-sparing mastectomy with immediate implant-based breast reconstruction-an analysis of initial 116 patients from single institution

Background

Endoscopic or robotic surgeries can minimize and hide the scars compared to conventional breast reconstruction but are considered unsuitable for bilateral procedures due to the extended operation time. This study explored a novel time-shortening endoscopic technique, namely reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with bilateral implant-based breast reconstruction (BIBR), and compared it with conventional open surgery in clinical and cosmetic outcomes.

Methods

We retrospectively analyzed patients who underwent BIBR in the West China Hospital from January 2017 to June 2022. Patient characteristics, operation time, postoperative complications, breast satisfaction, and Scar-Q scores were compared between endoscopic and conventional open groups.

Results

Among 116 patients, 76 underwent R-E-NSM with BIBRs (R-E-BIBR group), and 40 underwent conventional open BIBRs (C-O-BIBR group). The demographics and clinical data were similar primarily (P > 0.05). Compared with the C-O-BIBR group, the R-E-BIBR group had lower rates of total (32.5% versus 6.6%, P < 0.001), major (13.8% versus 2.0%, P < 0.001) and minor (23.8% versus 3.9%, P < 0.001) complications. The operation time between the two groups is not statistically significant (290.2 ± 95.2 mins versus 271.9 ± 95.3 mins, P = 0.327). The Harris scale scored breast satisfaction, and the excellent rate of the C-O-BIBR group was 32.5% while the R-E-BIBR group was 58.0% (P < 0.001). The mean Scar-Q scores were 35.17± 9.6 in the C-O-BIBR group and 81.32 ± 12.3 in the R-E-BIBR group, respectively (P < 0.001).

Conclusion

The innovative R-E-NSM with implant-based breast reconstruction makes up for the long operation time of previous endoscopic surgeries and has significant advantages in reducing complication rates and improving the cosmetic results of the postoperative breasts.

Secondary Revision after Breast Reconstruction with Free Abdominal Perforator Flap: Flap Liposuction and Inframammary Fold Reconstruction

Background

In breast reconstruction using the abdominal perforator flap, if the flap capacity is too large, secondary revision procedures can be performed to reduce flap volume and reconstruct the inframammary fold (IMF). We examined the various revision methods and cosmetic results.

Methods

This study included 28 patients who underwent secondary revision among 216 patients who had breast reconstruction using the abdominal perforator flap between April 2012 and March 2019. The revision method, removal ability, and the inferior breast point (IBP) were analyzed using medical records.

Results

Revision methods included incision resection in 4 cases, liposuction (LS) in 22 cases, LS and simultaneous IMF reconstruction in 2 cases, and post-LS IMF reconstruction in 1 case. The average LS amount was 317 mL (range, 100 --700 mL). In 22 patients who underwent LS, the difference in preoperative IBP was 1 cm or more in 19 (86.4%) cases and 1 cm or less in 3 (13.6%) cases. The difference in postoperative IBP was 1 cm or more in 12 (54.5%) cases and 1 cm or less in 10 (45.5%) cases. The receiver operating characteristic curve analysis revealed that the cutoff LS amount for a postoperative IBP difference of 1 cm or less was 375 mL.

Conclusions

The IBP was increased due to the decrease in flap volume. Revisions were completed with no difference in the LS-only IBP, especially when the LS amount was less than 375 mL. If the removal of 375 mL or more is necessary, removal or reformation of the IMF can be considered. These findings can potentially guide the planning of surgical procedures.

Defining the Inframammary Fold by Liposuction: An Essential Tool in Aesthetic Shaping of the Reconstructed Breast. Technique and Long-term Results in a Series of Patients

Background

A good inframammary fold (IMF) definition and position is essential to achieve a satisfactory and natural result in breast surgery. This structure can be damaged, especially during mastectomies. Multiple methods are reported in the literature to restore IMF or improve its definition. In this study, we present the results achieved in a series of patients treated with subdermal liposuction.

Methods

We report on all our patients who underwent IMF liposuction between January 2016 and June 2020. Subdermal liposuction was performed with a blunt 3 mm cannula along the new IMF to promote skin retraction and adherence between skin and fascia. Results were evaluated subjectively by the patients and objectively by 8 individuals not involved with the treatment.

Results

We performed IMF liposuction in 88 breasts (69 patients), aged 21–74 (mean 52) years for 82 implant-based reconstructions, 2 tuberous breasts, and 4 contralateral breast augmentations. Mean follow-up was 28 months (6–64). Subjective results: the overall result evaluated with the VAS scale reached 86.6/100. All the 22 patients interviewed judged as well defined the new inframammary fold. Objective results: in 83% of cases the definition of the inframammary fold was judged as good or excellent, while symmetry with contralateral IMF, natural appearance, and overall aesthetic outcome were judged as good.

Conclusion

Based on our long-term satisfactory results, we recommend the technique of subdermal liposuction to improve the definition of IMF in breast reconstruction after mastectomy and other breast procedures. It is effective, easy to perform, minimally invasive, and durable.

Latest Advancements in Autologous Breast Reconstruction

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Understand the available donor sites for autologous breast reconstruction. 2. Describe the advantages and limitations of each donor site. 3. Provide a rational, algorithmic preoperative evaluation and approach for patients seeking autologous breast reconstruction. 4. Develop an effective postoperative monitoring system to minimize complications and maximize salvage of microvascular thromboses.

SUMMARY

Breast reconstruction remains at the heart of the field of plastic and reconstructive surgery, and it is continuously evolving. Tremendous advances in breast implant technology and supplemental products, particularly acellular dermal matrices, have revolutionized breast reconstruction in the modern era. However, microvascular free flap breast reconstruction has also witnessed profound advancements with exceptionally high success rates, with the ability to provide the most durable and natural breast reconstruction. Although the pendulum oscillates between prosthesis-based reconstruction and autologous tissue, the present synopsis will focus on autologous free flap breast reconstruction from an historical perspective, recent advancements in microsurgery, and the future of autologous breast reconstruction.

A Simple and Scarless Method for Inframammary Fold Correction Using a Barbed Suture

Background:

In the typical procedure for secondary correction of the inframammary fold (IMF) following breast reconstruction, a large incision is often required, and this increases surgical invasiveness. The “drawstring method” is a simple procedure for recreating a smooth IMF. We modified the drawstring method and developed an essentially scarless method for IMF correction from small stab incisions.

Methods:

Patients at our hospital who presented with IMF ptosis or loss of definition after breast reconstruction and required IMF correction, as well as those who requested IMF recreation for the contralateral breast, during the period spanning May 2016 to June 2019 were considered for this study. We collected and analyzed demographic data, as well as complications and postoperative outcomes.

Results:

The new method was performed on 20 patients, with the following breakdown: IMF recreation after breast reconstruction with a deep inferior epigastric artery perforator flap (11 patients), IMF recreation after breast reconstruction with a breast implant (2 patients), IMF recreation after breast reconstruction with fat graft (5 patients), and IMF recreation for the contralateral breast (2 patients). Overcorrection of the IMF stabilized by 2–3 months postoperatively, resulting in a smooth and well-defined IMF. For non–breast implant cases, the implant volume increased at the lower pole. Slack in the suture was observed in only 2 patients of the deep inferior epigastric artery perforator group and in 1 patient of the breast implant group after 6 months postoperatively.

Conclusions:

Our new method allows for the recreation of an essentially scarless, smooth, and well-defined IMF. IMF definition can be adjusted by altering the depth of the barbed suture. Since this method can be performed under local anesthesia, it offers the benefits of reducing medical costs and physical burden on patients.
