Les pertes de substance sont une pathologie fréquente en chirurgie plastique, principalement après l'exérèse de cancer de la peau. Les résultats de la reconstruction nasale doivent répondre à des exigences esthétiques et fonctionnelles élevées. Une analyse minutieuse de la perte de substance est impérative pour évaluer les déficits anatomiques et esthétiques. Toute perte osseuse, cartilagineuse ou de la muqueuse doit être restaurée. Les lambeaux locaux permettent de couvrir les pertes de substances limitées. Le lambeau frontal est le lambeau de référence pour les plaies complexes. [less ▲]

Une chéloïde est une formation saillante, fibreuse hypertrophique du derme. Elle est très ferme au toucher. Il en existe deux types cliniques qui correspondent, d’une part, à une évolution particulière d’une cicatrice et, d’autre part, à une apparition présumée spontanée. Cette lésion est caractérisée par des dépôts massifs de faisceaux de collagène. Cet aspect la distingue de la cicatrice hypertrophique qui représente, de manière primordiale, une accumulation de fibroblastes et de petits vaisseaux. [less ▲]

Breast surgery currently remains very subjective and each intervention depends on the ability and experience of the operator. To date, no objective measurement of this anatomical region can codify surgery. In this light, we wanted to compare and validate a new technique for 3D scanning (LifeViz 3D) and its clinical application. Materials and methods. - We tested the use of the 3D LifeViz system (Quantificare) to perform volumetric calculations in various settings ("in situ" in cadaveric dissection, of control prostheses and in clinical patients) and we compared this system to other techniques (CT scanning and Archimedes' principle) under the same conditions. Results. - We were able to identify the benefits (feasibility, safety, portability, low patient stress) and limitations (underestimation of the “in situ” volume, subjectivity of contouring, and patient selection) of the LifeViz 3D system, concluding that the results are comparable with other measurement techniques. Conclusion. - The prospects of this technology seem promising in numerous applications in clinical practice to limit the subjectivity of breast surgery. [less ▲]

Autologous fat grafting for breast is increasing dramatically. This fat injection needs accurate technical conditions, and shows very good and long-lasting clinical results. Nevertheless, in breast conservative treatment sequellae, fat injection could lead to difficulties in breast imaging, but also there is some concerns about the potential oncologic risks of these procedures.

Oncoplastic surgery combines large lumpectomy and defect remodeling by different plastic surgery methods. These procedures improve the cosmetic result after partial mastectomy and widens the possibilities for conservative treatment. Different techniques are used from simple glandular remodeling to more difficult techniques for breast plasties with or without simultaneous controlateral symetrisation procedure. The surgical option depends especially on the ratio between the volume of the tumor and the volume of the breast and the position of the tumor. This more effective conservative treatment facilitates also postoperative radiotherapy, reduces the sequellae and the psychological impact of breast cancer treatment. [less ▲]

La reconstruction mammaire est actuellement partie intégrante de la prise en charge du cancer du sein. Lorsqu’elle est proposée en immédiat, plusieurs contraintes se présentent au chirurgien plasticien. La prise en charge des patientes devant bénéficier d’une mastectomie se complique par les traitements complémentaires de radiothérapie. Nous proposons, dans ce travail, une prise en charge multidisciplinaire des patientes en les adressant à des sous-groupes spécifiques. Une reconstruction immédiate sera proposée à certaines patientes compte tenu des traitements complémentaires par radiothérapie. Les choix d’orientation sont complexes et une littérature pauvre à ce sujet ne nous permet pas d’orienter de façon systématique toutes les patientes. De nouvelles études, notamment prospectives, sont nécessaires pour orienter les patientes désirant une reconstruction immédiate associée à une radiothérapie post-mastectomie. [less ▲]

Breast reconstruction is now an integral part of breast cancer treatment. There are several different procedures that make use of flaps or prostheses, or a combination of the two. Which of these procedures is indicated depends on the sequelae of the initial treatment and the patient's wishes and morphology. However, the constraints caused by the prosthetic material and the now regular use of microsurgical techniques have greatly favoured the purely autologous options. The different surgical techniques and their respective advantages and disadvantages will be described, before considering the timing of the various stages of the procedure. We will also give a summary of our experience with free flaps. [less ▲]

Benign symmetric lipomatosis is a rare form of typical fat distribution in the shoulders, the arms, and the neck that can compromise the respiratory, nutritional, and psychological status of the patient. Alcoholism, malignant tumors of the upper airways, endocrine tumors, hypothyroidism, diabetes, and hypertriglyceridemia are often associated with its occurrence. Surgical removal via lipectomy or liposuction can give good cosmetic results, although recurrences often occur. Liposuction has become the first choice to treat this disorder in patients with smaller masses. We have operated on four such cases in which liposuction failed and surgical excision had to be performed. We present a summary of the clinical characteristics of all four patients and discuss the different treatment options. [less ▲]

The body posture and gravitational forces govern in part the intrinsic skin tensile strength because they influence the orientation of the dermal fibre networks. Our objective was to assess changes in shear wave propagation in the skin according to the body posture and orientation of the gravitational forces. The study was performed in 30 middle-aged women with a normal body mass index. The Reviscometer was used to assess the mechanical wave propagation on the volar forearm in extension or flexion. Similar measurements were made on the supra-areolar region of the breast when the trunk was in the horizontal or vertical position. Four measurements were made in each of 4 directions at given angles with regard to the body axis. The device gave reproducible data. Shear wave propagation was influenced by the body posture. The intra-individual variability in shear wave velocity according to the directions of measurements increased when the tissues were in a relaxed position. Skin tensile anisotropy increased in a relaxed body posture. Shear wave propagation may be a convenient non-invasive tool to better identify the natural skin tension lines in the skin, thus refining the orientation of incision during cutaneous surgery.
