New Abdominal Flap Design for Breast Reconstruction in Association with the Thoracoabdominal Flap:

Nipple reconstruction using rib cartilage strut in microsurgical reconstructed breast

Nipple areolar reconstruction is the very last step of breast reconstruction. It is of outmost importance because it gives final appearance of breast, which is then better integreated by the patient in her body image. A lot of techniques are described to recreate nipple projection, from trompe l'œil tattoo to local flap, nipple sharing or autologous tissue graft. Common drawback of these techniques is nipple flattening with time, due to tissue atrophy. We present here a technique to use rib cartilage graft as structural framework for nipple reconstruction. Rib cartilage is stored in a pocked created in the groin during first step of breast microsurgical reconstruction. During nipple-areolar reconstruction, graft is cut at appropriate size and used inside a C-V flap to enhance nipple projection. Results show excellent symmetry and projection and is stable over time. Patients are very satisfied and can better integrate their new breast.

Maximizing the Volume of Latissimus Dorsi Flap in Autologous Breast Reconstruction with Simultaneous Multisite Fat Grafting

BACKGROUND

The pedicled latissimus dorsi (LD) flap serves an important function in breast reconstruction, but its utility is limited by its inability to provide sufficient breast volume.

OBJECTIVES

The purpose of this preliminary report was to review the techniques and outcomes of utilizing fat-grafted, volume-enhanced LD flap transfer with fat grafting recipient sites in autologous breast reconstruction.

METHODS

A retrospective study was performed of 10 patients (14 breasts) who underwent autologous breast reconstruction utilizing the LD flap transfer technique and simultaneous fat grafting between August 2012 and September 2014. Multilayer, multisite fat grafting was performed to the LD muscle, LD skin paddle, mastectomy skin flaps, and the pectoralis major and serratus muscles simultaneously with the LD flap transfer.

RESULTS

Three patients underwent an immediate breast reconstruction, four underwent a delayed breast reconstruction, and four underwent a tertiary breast reconstruction following previously failed breast reconstructions (one patient underwent each of the first two procedures, one on each breast). The average age of the patients was 55 years (range, 39-76 years), the average body mass index of the patients was 29.3 (range, 19.6-39.9), and the average fat grafting volume for the patients was 176 mL (range, 50-300 mL). There was 100% flap survival and complete wound healing. No seroma or fat grafting-related complications were clinically detected. Three patients required additional fat grafting.

CONCLUSIONS

The fat-grafted, volume-enhanced LD flap procedure with fat grafting recipient sites offers a simple and safe technique for autologous breast reconstruction, with low morbidity and fast recovery. It can be a useful alternative to utilizing abdomen-based flaps in autologous breast reconstruction or could be performed to salvage both implant-based and free-flap breast reconstructions.
