SAMCEP Society consensus on the treatment of upper facial lines with botulinum neurotoxin type A: A tailored approach.

BACKGROUND: The safety and efficacy of botulinum neurotoxin type A (BoNTA) treatments are well established, but injection techniques, target muscles, and toxin doses continue to evolve, with each refinement producing improvements in treatment outcomes. The recommendations in this consensus move away from standard templates and illustrate how to tailor treatments to individual patterns and strengths of muscle activity, and patient preferences. METHODS: Seventeen experts in the fields of plastic surgery, dermatology, ophthalmology, otorhinolaryngology, and neurology convened in 2022 to develop consensus-based recommendations for the use of botulinum toxin A for the treatment of horizontal forehead lines, glabellar frown lines, and crow's feet lines that reflect current clinical practice. The focus was on how to tailor injections to individual patients to optimize treatment outcomes. RESULTS: For each upper face indication, consensus members describe how to perform a dynamic assessment to optimize the dose and injection technique for each patient. A tailored treatment protocol is presented for commonly observed patterns of dynamic lines. Units of Inco are defined and the precise location of injection points, illustrated with the use of anatomical images. CONCLUSION: This consensus provides up-to-date recommendations on the tailored treatment of upper facial lines based on the latest research and collective clinical experience of the expert injectors. Optimal outcomes require thorough patient evaluation, both at rest and during animation, using both visual and tactile cues; detailed understanding of facial muscular anatomy and how opposing muscles interact; and use of a BoNTA with high precision to target identified zones of excess muscle activity.

[Breast reconstruction with profunda artery perforator flap: A prospective study of 30 consecutive cases]. / Reconstruction mammaire par profunda artery perforator flap : étude prospective des 30 premiers cas consécutifs.

INTRODUCTION: Many flaps have been described in autologous breast reconstruction, the most common being the deep inferior epigastric perforator (DIEP) flap. This flap cannot be harvested in a certain range of patients. The profunda artery perforator (PAP) flap, based on perforators from profunda femoral artery, is therefore a good option. OBJECTIVE: The goal was to highlight technical tips, particularities, and complications of our series of the 30 first PAP flaps for breast reconstruction in our department. PATIENTS AND METHOD: We did a prospective study of all PAP flaps for breast reconstruction between November 2014 and October 2015. Thirty patients were included. We used 2 different types of skin design: classical or with vertical extension. The following parameters were recorded: pedicle length, flap weight, surgery duration, complications on donor or recipient site and type of recipient vessels. RESULTS: Seventy-seven percent of the cases were delayed breast reconstruction, 23% were immediate. Twenty-five flaps were with classical skin design, and 5 with vertical extension. Mean flap weight was 301g (195-700g). Mean pedicle length was 9.88cm (8.2-12.5cm). Internal mammary vessels were the recipient vessels for 90% of the patients, versus 10% for circumflex scapular vessels. Mean surgery duration was 328min (195-610min). We had two total flap failures. The complications on the donor-site were 2 seroma, and 4 late healing scars. No lymphoedema occurred. CONCLUSION: PAP flap is a good option when abdominal flap harvesting is not possible. The donor-site is well tolerated, with low morbidity. The indication is for patients with small to medium breast volume.

[Breast reconstruction with Profunda Artery Perforator flap in lithotomy position. Surgical technique]. / Reconstruction mammaire par Profunda Artery Perforator flap prélevé en position gynécologique. Technique chirurgicale.

Autologous breast reconstruction provides great cosmetic, functional and sustainable incomes. Various flaps have been described in autologous breast reconstruction, Deep Inferior Epigastric Perforator flap (DIEP) being the most frequent. For patients with a non-sufficient abdomen for a DIEP based breast reconstruction, the Profunda Artery Perforator Flap (PAP), based on profunda arteris perforators, is a current trend, but few publications detailed the flap harvest. Comparing with a TUG flap, the morbidity linked to the muscle harvest is decreased. Usually the dissection is done in prone or in "frog leg" position. The aim is to describe a technical option: we propose a different position, with a harvest of the PAP in lithotomy position. It offers additional comfort and security for the surgeon and decreases the operative time. The pedicle had an average of 7cm in length; the artery diameter was 2.2mm and the vein 2.5mm. The cosmetic incomes are very good six months postoperative.

[Morphological evaluation of genioplasty associated with orthognathic surgery]. / Évaluation morphologique des génioplasties associées à la chirurgie orthognathique.

INTRODUCTION: The maxillo-mandibulary dysphormias are frequently associated with morphological abnormalities of the chin. Their correction in the sagittal and transverse planes can benefit both morphologically and functionally. The purpose of this study was to evaluate the morphological benefit of the osseous genioplasty associated with orthognathic surgery depending on the type of technique used, as well as complications occurred. PATIENTS AND METHODS: We identified patients who underwent osseous genioplasty associated with orthognathic surgery in our department between 2004 and 2010. For each patient Angle class, type of osteotomy, genioplasty and postoperative complications were recorded. The morphological results were evaluated by a group of surgeons and a group of observers using standardized photographs. RESULTS: Of the 203 facial osteotomies performed during this period, 101 osseous genioplasties were made. In most cases, there was a height reduction associated with advancement of the chin. The morphological results were considered as satisfactory all evaluators alike (3.92). The best results were obtained in height reductions with advancement techniques as sliding genioplasty (4.03) and jumping divided genioplasty (4.19). Five patients (5.9%) had a postoperative complication. This was especially one mental nerve injury and two dental mortifications. No default of consolidation or necrosis or hematoma of mouth floor have been reported. CONCLUSION: Osseous genioplasty is a safe, reliable procedure with morphological satisfactory outcome, in combination with orthognathic surgery. The best results were obtained with cases of height reduction with advancement of the chin, especially the original technique of the jumping divided genioplasty.
