Updates on Breast Reconstruction: Surgical Techniques, Challenges, and Future Directions

Figures

Figure 1.
Figure 1. Types of implants and anatomical planes of reconstruction. This figure shows a flowchart of implant types and anatomical planes. In terms of contents, silicone implants are preferred for their softness, while smooth implants are favored due to concerns about breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). For the anatomical plane, the prepectoral option is chosen when the mastectomy flap has sufficient thickness. The use of acellular dermal matrix (ADM) is required in the prepectoral plane.
Figure 2.
Figure 2. Subpectoral reconstruction. The tissue expander (TE) is inserted into the subpectoral plane. After several months of percutaneous saline infusion and gradual expansion, the TE will be replaced with the breast implant.
Figure 3.
Figure 3. Subpectoral reconstruction with acellular dermal matrix (ADM). The pectoralis major muscle is detached inferiorly, and then sutured to the ADM to create a single plane. This eliminates the need for expanding the pectoralis major muscle using a tissue expander (TE), allowing for the implant to be inserted in a single phase.
Figure 4.
Figure 4. Prepectoral reconstruction. The breast implant is entirely covered with acellular dermal matrix (ADM) and inserted at the anterior aspect of pectoralis major muscle. This method is less invasive and becoming more widely used.
Figure 5.
Figure 5. Representative examples of flaps used in autologous breast reconstruction. The LDMC flap is a pedicled myocutaneous flap, while the others are free perforator flaps that require vascular anastomoses. LDMC flap: latissimus dorsi myocutaneous flap; DIEP flap: deep inferior epigastric artery perforator flap; LAP flap: lumber artery perforator flap; PAP flap: profunda artery perforator flap; GAP flap: gluteal artery perforator flap.

Table 1. Patient Selection Criteria for Breast Reconstruction Methods
 
Breast reconstruction methodImplantsAutologous tissue
This table compares the selection criteria for breast reconstruction using implants versus autologous tissue. The decision on which reconstruction method to use is primarily based on the patient’s preference, with careful consideration of the respective benefits and drawbacks of each method. The implant option involves using synthetic materials, while autologous tissue reconstruction uses the patient’s own tissue. Both methods have distinct advantages and disadvantages that should be discussed with the patient to ensure an informed decision. PROs: patient-reported outcomes; BIA-ALCL: breast implant-associated anaplastic large cell lymphoma.
AdvantagesDo not require a donor siteMinimal maintenance
Less invasiveUndergoing similar age-related changes
Choice of donor based on breast size and body shape
Superior to implants in PROs [10-12]
DisadvantagesRupture [6]Require a donor site
Capsular contracture [6, 7]More invasive
BIA-ALCL [8]Risk of flap loss
Breast implant illness [9]
Inferior to autologous tissue in PROs [10-12]
