From the SAFE to the SAFEST Liposuction: Combining PAL and RFAL Technology in Body Contouring Procedures.

BACKGROUND: The SAFE liposuction technique is a worldwide extended method used to achieve great and reproducible results after the surgical aspiration of fat. We propose an evolution of the technique to address one of the major limitations of liposuction, loose skin. The SAFEST liposuction technique combines PAL and RFAL to achieve skin tightening and fat reduction with minimal added morbidity. METHODS: Patients treated with the SAFEST liposuction technique between December 2019 and February 2022 were included in the study. Demographic and surgical data were collected retrospectively. Photographs and satisfaction interviews were conducted preoperatively and 12 months postoperatively in every case. RESULTS: Sixty-five patients (58 female and 7 male) were included in the cohort, and a total of 169 anatomical areas were treated with the SAFEST liposuction technique (abdomen, arms, back, flanks and thighs). Globally, satisfaction at 12 months follow-up was of 94.1% and complications only presented in 4.7% of the treated areas. 6 of the 38 treated abdomens (18.4%) presented a complication (4 seromas and 2 access point infections) and 2 of the 38 treated flanks (5.3%) presented one (2 seromas). The rest of the treated anatomical areas (arms, back and thighs) showed no complications and high satisfaction rates. CONCLUSIONS: The SAFEST liposuction technique achieves outstanding and satisfying results with minimal complications by safely combining the advantages of two different technologies, PAL and RFAL. The main advantages of the presented technique are the skin tightening, the body ligament contraction, the coagulation and the reduction of the operative time.

The MICRO-Lift: A Ligaments-Based Anatomic Technique for Lower Face and Neck Rejuvenation Using Bipolar Radiofrequency.

BACKGROUND: The aim of this paper is to present the results of a new technique for lower face and neck rejuvenation named the MICRO-lift (Minimally Invasive, Combined Radiofrequency, Outpatient lift). This technique is based on a bipolar radiofrequency treatment applied to specific ligamentous areas. METHODS: Inclusion criteria were patients with skin laxity of the neck and jowls, with or without fat accumulation. Patients who presented platysma sag and alteration of subplatysmal structures were excluded from the study. The distribution of the energy was adapted to the ligament anatomy, differentiating three areas based on the energy concentration. In all patients, sex, age at surgery, type of anesthesia, radiofrequency parameters and complications were registered. In all cases, standard photographs and satisfaction interviews were conducted preoperatively and postoperatively. Satisfaction evaluation was also assessed. RESULTS: Sixty-five patients underwent MICRO-lift technique for the lower face and neck. All patients in our series were female. There were no major complications. Minor complications included transient paralysis of the marginal mandibular (4,6%), infection of the submental incision that required incisional drainage (3,1%), and deep skin burn in the neck (1,5%). Fifty-nine patients were satisfied a year after the treatment (90,8%). CONCLUSIONS: The MICRO-lift can produce outstanding and satisfying improvements in cervicofacial appearance. This new approach offers a predictable strategy to achieve the desired aesthetic results, making this procedure more reliable and reproducible for both novel and experienced surgeons with bipolar radiofrequency.

Maximizing the Smile Symmetry in Facial Paralysis Reconstruction: An Algorithm Based on Twenty Years' Experience.

Over the last two decades, the senior author (B.H.) has had an extensive experience with facial paralysis reconstruction. During this period, the techniques have evolved substantially based on the experience and after observing and analyzing the surgical outcomes. The purpose of this article is to relay the lessons learned from the 20 years' experience and suggest an algorithm. In this retrospective study, we have included 343 cases of facial paralysis cases. Complete facial paralysis cases were 285 and 58 were incomplete facial paralyses, both requiring surgical procedures. Complete facial paralyses were divided in to short term (n = 83) and long term (n = 202). In total, 58% of the patients were women and 42% were men. The age range was 6 to 82 years. The techniques employed were direct suture, nerve grafts, cross-facial nerve grafts (CFNGs), masseteric-to-facial nerve transference, hypoglossal-to-facial nerve transference, free muscle transplants, and lengthening temporal myoplasty to achieve the best symmetry after reanimation of unilateral, bilateral, complete, and incomplete facial paralysis. The type of paralysis, objective measurements, the personal patient's smile, and the gender are key concepts to be considered before scheduling a dynamic facial paralysis reconstruction. For unilateral facial paralysis, the time of onset, the type of paralysis, the patient's comorbidities, and the healthy side status are some of the determining factors when selecting the correct technique. The preferred techniques for unilateral facial paralysis are direct repair, CFNG, masseteric-to-facial transposition, and free gracilis transfer. For incomplete facial paralysis, the masseteric-to-facial nerve transference is preferred. In bilateral facial paralysis, bilateral free gracilis transfer is performed in two stages using the nerve of the masseter muscle as the source of innervation. The authors provide an algorithm which simplifies facial paralysis reconstruction to achieve the greatest facial symmetry while thinking about the potential comorbidities and developing spontaneity smile according to the gender of the patient.

A Pinch Test to Correct an Unfolded Helix: An Innovative and Predictable Technique.

The unfolded helix is an ear deformity more frequent than expected. It might be presented alone or combined with other scapha or concha anomalies, giving the appearance of big and prominent ears. Currently, there are few reports published about its restoration and few modifications have been made to its original surgical approaches since the 1970s. The technique herein described aims to facilitate the helix rim restoration procedure by considering the following preoperative and surgical advices. The preoperative use of the pinch test allows to better understand the patients' expectations, helps to explain the future outcomes to them and simplifies the marking of the tissue to be removed. The additional bilateral only-cartilage resections and the maintenance of the skin excess permit to optimize the cosmetic outcomes. This innovative surgical approach for the helix rim restoration is reliable, has little morbidity associated and presents consistent effective results.

Inverted Nipple Correction Techniques: An Algorithm Based on Scientific Evidence, Patients' Expectations and Potential Complications.

BACKGROUND: Inverted nipple is a problem that affects a large number of women, with an aesthetic and functional repercussion. The literature is abundant in terms of techniques described, from the most conservative to the most aggressive. Although different techniques have been described to correct inverted nipples, there are no established algorithms to guide the surgeon in choosing the correct technique for each patient. Therefore, the objective of this paper is to present the first algorithm to simplify the inverted-nipple approach, based on the most recent scientific evidence and the patient's wishes. METHODS: A bibliographic review on this pathology and available treatments was carried out to build an algorithm. Then, 47 patients consulting about inverted nipple concerns were included in this study. First, the patient's breastfeeding concerns were discussed. Once breastfeeding concerns were known, exploration of inverted nipple and assessment based on the degree of severity was done. Different techniques were proposed according to the degree of inverted nipple. Our technique was indicated in the most severe cases of retraction. RESULTS: Forty-seven surgical and non-surgical procedures were carried out, resulting in excellent outcomes and high satisfaction rates. No complications or recurrence were observed after 1-year follow-up. CONCLUSIONS: This is the first time an algorithm to simplify the approach of the inverted nipple has been proposed based on the degree of severity and lactation wishes. Choosing the right procedure for each patient will help the plastic surgeon in achieving great satisfaction and an excellent aesthetic result.

Improving Cost-efficiency in Bilateral Direct-to-Implant Reconstructions with Acellular Dermal Matrix.

The use of acellular dermal matrix (ADM) for bilateral breast reconstruction has increased in recent years. Detection of BCRA mutation and therefore bilateral risk-reduction mastectomy is one of the main reasons for this increase. High cost of ADM is considered a major drawback for its use. The authors present a new technique which allows the use of only one unit of ADM for both breasts. After assessing the viability of the skin of mastectomy flaps, a musculofascial pocket formed superiorly by pectoralis major, laterally by serratus fascia and inferiorly by rectus fascia, is performed. Then, the ADM is divided in two halves. We propose two different ways to divide the matrix, cutting it vertically or diagonally in two. The way in which the matrix should be cut depends on the distensibility of the pocket. Afterwards, the implant is inserted and the exposed area of the implant is covered by the ADM sutured to the edges of the musculofascial pocket. Using only one ADM unit for bilateral reconstruction, the procedure becomes not only more cost-effective but also can reduce complications such as seroma, rippling, wrinkling, and visibility by means of a better coverage with lesser foreign body load. Furthermore, the lesser the matrix used, the faster the integration is achieved.
