[Mastectomy and immediate reconstruction: Indications, techniques and decision algorithm]

Immediate breast reconstruction indications extend to infiltrating carcinomas, due to new matrix implant coverage techniques and the development of perforator flaps. These techniques allow adjuvant treatments. However, the decision of immediate reconstruction must be discussed with the oncological multidisciplinary team and the benefits/risks must also be evaluated in relation to the morphology of the patients and their co-morbidities. The chosen type of mastectomy: conventional or skin sparing and/or nipple sparing depends on the shape and volume of the breast, the localization of the tumor in the breast and the distance from the nipple areola complex (NAC). We describe an algorithm to allow, in the case of therapeutic mastectomy with or without adjuvant radiotherapy, an immediate reconstruction with implants or free or pedicled flaps.

[Decision algorithm in immediate breast reconstruction]

Immediate breast reconstruction showed many advantages in terms of aesthetic and functional results and improvement of quality of life when compared to delayed breast reconstruction. Previous radiotherapy or the use of adjuvant treatments such as radiation therapy, or chemotherapy are no longer a contraindication for immediate breast reconstruction. However, it is important to respect certain rules in order to decrease the risk of complications: the choice of reconstruction technique, the management of the skin envelope according to the breast shape you want to create, the time delay between the first and the second stage of reconstruction depending on a possible adjuvant treatment.

[The sural medial perforator flap: Anatomical bases, surgical technique and indications in head and neck reconstruction]

INTRODUCTION

The medial sural artery perforator (MSAP) flap is defined as a thin cutaneo-adipose perforator flap harvested on the medial aspect of the leg. The aims of this study were to describe the anatomical basis as well as the surgical technique and discuss the indications in head and neck reconstructive surgery.

MATERIAL AND METHODS

We harvested 10 MSAP flap on 5 fresh cadavers. For each case, the number and the location of the perforators were recorded. For each flap, the length of pedicle, the diameter of source vessels and the thickness of the flap were studied. Finally, we performed a clinical application of a MSAP flap.

RESULTS

A total of 23 perforators with a diameter superior than 1mm were dissected on 10 legs. The medial sural artery provided between 1 and 4 musculocutaneous perforators. Perforators were located in average at 10.3cm±2cm from the popliteal fossa and at 3.6cm±1cm from the median line of the calf. The mean pedicle length was 12.1cm±2.5cm. At its origin, the source artery diameter was 1.8mm±0.25mm and source veins diameters were 2.45mm±0.9mm in average. There was no complication in our clinical application.

DISCUSSION

This study confirms the reliability of previous anatomical descriptions of the medial sural artery perforator flap. This flap was reported as thin and particularly adapted for oral cavity reconstruction and for facial or limb resurfacing. Sequelae might be reduced as compared to those of the radial forearm flap with comparable results.

Full-thickness skin grafts for lower leg defects coverage: Interest of postoperative immobilization

INTRODUCTION

Full-thickness skin graft is an effective reconstruction method after excision of skin lesions on the lower limb that are not amenable to primary closure. The randomness of graft take is the major drawback of this procedure.

OBJECTIVE

The objective of the study was to evaluate the outcome of full-thickness skin grafts (FTSG), used to repair lower leg defects after excision of skin lesions, after a 5-day immobilization period.

MATERIAL AND METHODS

All consecutive patients who underwent FTSG to cover defects below the knee between November 2011 and January 2016 were retrospective reviewed. Graft take was assessed and defined as good (>90% graft take), moderate (between 50% and 90% graft take), or poor (<50% graft take).

RESULTS

Seventy patients were included. Median age was 70 years (range, 18-92 years). The median area of the defect was 12cm². Graft take was good in 64 patients (91.4%), moderate in 3 patients (4.3%), and poor in 3 patients (4.3%) at Day 5. Complications included hematoma (11%), infection (14%) and venous thrombosis (3%).

CONCLUSION

Full-thickness skin graft is a reliable method to repair defects on the lower leg after removal of skin lesions. A 5-day immobilization period can improve the graft take. The authors have indicated no significant interest with commercial supporters.
