Inferolateral AlloDerm hammock for implant coverage in breast reconstruction

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Biomaterials in Medicine

Background:

• Implant reconstruction is a common procedure for addressing mastectomy defects and breast hypoplasia.
• The inferolateral AlloDerm hammock serves as an inferior extension of the pectoralis major muscle.
• This technique creates a barrier between the implant and skin, aiding in implant positioning.

Purpose of the Study:

• To evaluate the efficacy of the inferolateral AlloDerm hammock in breast implant reconstruction.
• To assess its role in both immediate and revisional breast reconstruction procedures.

Main Methods:

• The AlloDerm hammock's inferior border was secured to the rectus abdominis and serratus anterior fascia.
• The AlloDerm was sutured to the pectoralis major muscle to fully enclose the implant.
• This method was applied in various reconstruction scenarios, including immediate and delayed expander-implant and silicone implant reconstructions, as well as revisional surgeries.

Main Results:

• The technique was utilized in 43 patients across 67 breasts.
• It ensured complete implant coverage and symmetric inframammary fold positioning.
• In delayed reconstructions, it reduced the need for further filling by recruiting inferior epigastric tissue.
• No instances of capsular contracture, hematoma, or seroma were reported within 6 months to 3 years of follow-up.

Conclusions:

• The inferolateral AlloDerm hammock technique simplifies implant positioning in immediate and revisional breast reconstruction.
• It is an easy-to-learn and safe option for expander-implant reconstruction.
• This method is a viable choice for patients undergoing breast reconstruction.
