RESUMEN

BACKGROUND: An increasing number of aesthetic surgery procedures are being performed in an ambulatory fashion in office-based settings. Postoperative monitoring of these patients has historically required paid private-duty nurses measuring vital signs, encouraging ambulation, and monitoring overall comfort level. Recently, advancements in nanotechnology have permitted high-acuity data acquisition of multiple clinical parameters that can be transmitted to the surgeon's mobile device in a continuous fashion. OBJECTIVE: The aim of this study was to describe the authors' early experience with this emerging artificial intelligence technology in the postoperative setting. METHODS: Twenty-three consecutive patients underwent radiofrequency-assisted liposuction and Brazilian butt lift surgery, and were placed in a monitoring garment, SimpleSense (Nanowear Technologies, Brooklyn, NY) postoperatively. The primary outcome was device usability, reflected by compliance with wearing the device and completeness of data collection. RESULTS: During the first 48 hours, 91% of patients wore the device for more than 12 hours per day. Only 39% were compliant with postoperative positioning. No postoperative events were detected. CONCLUSIONS: The quality of data collected enables detection of clinical derangements and can alert the surgeon in real time, prompting interventions such as drug administration, position changes, or presentation to the emergency room.

RESUMEN

INTRODUCTION: The COVID-19 pandemic requires us all to re-evaluate aesthetic practices to ensure optimal patient safety during elective procedures. Specifically, energy-based devices and lasers require special consideration, as they may emit plume which has been shown to contain tissue debris and aerosolized biological materials. Prior studies have shown transmission of viruses and bacteria via plume (i.e., HIV and papillomavirus). The purpose of this study was to evaluate plume characteristics of the Er:YAG resurfacing laser (Sciton; Palo Alto, CA) and compare it to the Morpheus8 fractional radiofrequency device (InMode; Lake Forest, CA). METHODS: Five patients who underwent aesthetic resurfacing and/or skin tightening of the face and neck were treated with the Er:YAG (Sciton Joule, Palo Alto, CA) and/or fractional radiofrequency (Morpheus8, Lake Forest, CA) between April 1 and May 11, 2020. Data collected included patient demographics, past medical history, treatment parameters, adverse events, particle counter data, as well as high magnification video equiptment. Patients were evaluated during treatment with a calibrated particle meter (PCE; Jupiter, FL). The particle meter was used at a consistent focal distance (6-12 inches) to sample the surrounding environment during treatment at 2.83 L/min to a counting efficiency of 50% at 0.3 µm and 100% at >0.45 µm. Recordings were obtained with and without a smoke evacuator. RESULTS: Of our cohort (n = 5), average age was 58 years old (STD ±7.2). Average Fitzpatrick type was between 2 and 3. Two patients received Er:YAG fractional resurfacing in addition to fractional radiofrequency during the same treatment session. Two patients had fractional radiofrequency only, and one patient had laser treatment with the Er:YAG only. There were no adverse events recorded. The particle counter demonstrated ambient baseline particles/second (pps) at 8 (STD ±6). During fractional radiofrequency treatment at 1-mm depth, the mean recording was 8 pps (STD ±8). At the more superficial depth of 0.5 mm, recordings showed 10 pps (STD ±6). The Er:YAG laser resurfacing laser had mean readings of 44 pps (STD ±11). When the particle sizes were broken down by size, the fractional radiofrequency device had overall smaller particle sizes with a count of 251 for 0.3 µm (STD ±147) compared with Er:YAG laser with a count of 112 for 0.3 µm (STD ±84). The fractional radiofrequency did not appear to emit particles >5 µm throughout the treatment, however, the Er:YAG laser consistently recorded majority of particles in the range of 5-10 µm. The addition of the smoke evacuator demonstrated a 50% reduction in both particles per second recorded as well as all particle sizes. CONCLUSION: Re-evaluation of the plume effect from aesthetic devices has become important during the COVID-19 pandemic. Further studies are required to characterize viability of COVID-19 viability and transmissibility in plume specimens. Based on this pilot study, we recommend that devices that generate little to no plume such as fractional radiofrequency devices be used in Phase I reopening of practice while devices that generate a visible plume such as Er:YAG laser resurfacing devices be avoided and only used with appropriate personal protective equipment in addition to a smoke evacuator in Phase IV reopening.

RESUMEN

Increasingly, patients are seeking minimally invasive methods to tighten skin and remodel adipose tissue. A large treatment gap exists among 3 types of patients: (1) the younger demographic, who increasingly desire soft tissue tightening without traditional operations, scars, and downtime; (2) patients with soft tissue laxity who are not "severe enough" to justify an excisional procedure, but not "mild enough" to rely on liposuction with soft tissue contraction alone; and (3) those with recurrent laxity who already underwent traditional excisional procedures. In these populations, plastic surgeons risk under- or overtreating with traditional methods. The purpose of this supplement is to describe the utility of radiofrequency (RF) microneedling (Fractora modified to Morpheus8 InMode Aesthetic Solutions, Lake Forest, CA) in combination with bipolar RF (FaceTite/BodyTite, InMode Aesthetic Solutions). By combining these procedures, the aforementioned treatment gap can be addressed. The RF microneedling allows for subdermal adipose remodeling and skin tightening. Addition of bipolar RF also tightens the skin by contraction of the underlaying fibroseptal network in addition to induction of neocollagenesis, elastogenesis, and angiogenesis at skin surface temperatures of 40° to 50°C. In our experience, these technologies have been effective and safe in these patient populations. Level of Evidence: 4.

RESUMEN

Hallmark deformities of systemic scleroderma are early onset and progressively disabling flexion contractures of the proximal interphalangeal (PIP) joints often in conjunction with extension or, less frequently, flexion contractures of the metacarpophalangeal (MCP) joints. Although surgical correction is generally recommended, a prevailing reluctance for operative treatment exists owing to the inherent ischemia of the disease with its potentially compromised healing capacity. Nonetheless, with recognition and preservation of the tenuous but well-defined and constant periarticular vascular networks of the PIP and MCP joints, articular reconstruction with uncomplicated wound healing can prove consistently successful for patients with scleroderma. This article describes the authors' preferred methods of PIP arthrodesis vascularized by the dorsal cutaneous arterial network and MCP silicone implant arthroplasty perfused by the dorsal metacarpal arterial plexus.

RESUMEN

BACKGROUND: Free flaps have a well-established role in breast reconstruction after mastectomy; however, their role in partial breast reconstruction remains poorly defined. We reviewed our experience with partial breast reconstruction to better understand indications for free tissue transfer. METHODS: A retrospective review was performed of all patients undergoing partial breast reconstruction at our center between February 2009 and October 2015. We evaluated the characteristics of patients who underwent volume displacement procedures versus volume replacement procedures and free versus pedicled flap reconstruction. RESULTS: There were 78 partial breast reconstructions, with 52 reductions/tissue rearrangements (displacement group) and 26 flaps (replacement group). Bra cup size and body mass index (BMI) were significantly smaller in the replacement group. Fifteen pedicled and 11 free flaps were performed. Most pedicled flaps (80.0%) were used for lateral or upper pole defects. Most free flaps (72.7%) were used for medial and inferior defects or when there was inadequate donor tissue for a pedicled flap. Complications included hematoma, cellulitis, and one aborted pedicled flap. CONCLUSION: Free and pedicled flaps are useful for partial breast reconstruction, particularly in breast cancer patients with small breasts undergoing breast-conserving treatment (BCT). Flap selection depends on defect size, location, and donor tissue availability. Medial defects are difficult to reconstruct using pedicled flaps due to arc of rotation and intervening breast tissue. Free tissue transfer can overcome these obstacles. Confirming negative margins before flap reconstruction ensures harvest of adequate volume and avoids later re-operation. Judicious use of free flaps for oncoplastic reconstruction expands the possibility for breast conservation.

RESUMEN

BACKGROUND: The use of heterotopic vascularized lymph node transfer (HVLNT) for the treatment of lower extremity lymphedema is still evolving. Current techniques, either place the lymph nodes in the thigh without a skin paddle or at the ankle requiring an unsightly and often bulky skin paddle for closure. We explored the feasibility of doing a below-knee transfer without a skin paddle using the medial sural vessels as recipient vessels and report our experience in 21 patients. METHODS: A retrospective review of all patients who underwent HVLNT to the medial calf was performed. Postoperative magnetic resonance angiography (MRA) and lymphoscintigraphy (LS) were analyzed to assess lymph node viability and function after transfer. RESULTS: Twenty-one patients underwent HVLNT to the medial calf. Postoperative imaging was performed at an average of 11 months after surgery. Thirteen patients had postoperative MRA, of whom 12 demonstrated viable lymph nodes. Seven patients underwent postoperative LS, of whom three demonstrated uptake in the transferred nodes. In the other four patients, the injectate failed to reach the level of the proximal calf. CONCLUSION: We provide proof of concept that HVLNT to the lower leg using the medial sural vessels without a skin paddle can result in viable and functional lymph nodes in the setting of lower extremity lymphedema.

RESUMEN

Background The medial sural vessels have been used extensively as donor vessels in free tissue transfer; however, there is sparse literature detailing their use as recipient vessels. The few existing reports involve small numbers of patients and describe operative approaches that are unnecessarily cumbersome. We explored our experience in free tissue transfer to the medial sural vessels and share a simplified operative approach to this recipient site. Methods A retrospective review was performed of all patients who underwent free tissue transfers to the medial sural vessels between December 2012 and December 2015 at a single institution. Preoperative imaging, operative approach, and technique for microvascular free tissue transfer to the medial sural vessels were reviewed. Postoperative results and complications were also analyzed. Results Using preoperative magnetic resonance angiography (MRA) to image the medial sural vessels and a retrograde perforator dissection technique, we successfully performed free tissue transfer to the distal medial sural vessels in 20 of 21 patients, representing the largest series reported. Postoperatively, 13 of 21 patients underwent MRA with a patent vascular pedicle demonstrated in all. There were no postoperative complications or resultant morbidities. Conclusion Surgeons should be aware of the medial sural vessels as a valuable recipient option for free tissue transfer to the lower extremity.

RESUMEN

Advances in microsurgical techniques have improved autologous reconstructions by providing new donor site options while decreasing donor site morbidity. Various preoperative imaging modalities have been studied to assess the relevant vascular anatomic structures, with magnetic resonance (MR) angiography traditionally lagging behind computed tomography (CT) with respect to spatial resolution. Blood pool MR angiography with gadofosveset trisodium, a gadolinium-based contrast agent with extended intravascular retention, has allowed longer multiplanar acquisitions with resultant voxel sizes similar to or smaller than those of CT and with improved signal-to-noise ratio and soft-tissue contrast while maintaining the ability to depict flow with time-resolved imaging. The resultant vascular detail enables precise evaluation of the relevant vascular anatomic structures, including the vessel course, size, and branching pattern, as well as the venous arborization pattern. In addition, any architectural distortion, vessel alteration, or injury from prior surgery can be depicted. The reporting radiologist should be aware of pertinent and incidental findings relevant to the planned surgery and the patient's disease so that he or she can assist the microsurgeon in flap design as a member of the multidisciplinary team. Given the lack of ionizing radiation exposure in patients who often have an elevated body mass index, high-spatial-resolution blood pool MR angiography has become the imaging reference standard for the preoperative assessment of perforator flap vascular and soft-tissue morphology in our practice.

RESUMEN

Reconstruction of bony craniofacial defects requires precise understanding of the anatomic relationships. The ideal reconstructive technique should be fast as well as economical, with minimal donor-site morbidity, and provide a lasting and aesthetically pleasing result. There are some circumstances in which a patient's own tissue is not sufficient to reconstruct defects. The development of sophisticated software has facilitated the manufacturing of patient-specific implants (PSIs). The aim of this study was to analyze the utility of polyether ether ketone (PEEK) PSIs for craniofacial reconstruction. We performed a retrospective chart review from July 2009 to July 2013 in patients who underwent craniofacial reconstruction using PEEK-PSIs using a virtual process based on computer-aided design and computer-aided manufacturing. A total of 6 patients were identified. The mean age was 46 years (16-68 y). Operative indications included cancer (n = 4), congenital deformities (n = 1), and infection (n = 1). The mean surgical time was 3.7 hours and the mean hospital stay was 1.5 days. The mean surface area of the defect was 93.4 ± 43.26 cm(2), the mean implant cost was $8493 ± $837.95, and the mean time required to manufacture the implants was 2 weeks. No major or minor complications were seen during the 4-year follow-up. We found PEEK implants to be useful in the reconstruction of complex calvarial defects, demonstrating a low complication rate, good outcomes, and high patient satisfaction in this small series of patients. Polyether ether ketone implants show promising potential and warrant further study to better establish the role of this technology in cranial reconstruction.

RESUMEN

Vascularized groin lymph node transfer (VGLNT) has been successfully used to treat lymphedema. However, lack of familiarity with the inguinal node anatomy and concerns regarding donor site morbidity have limited its widespread use. The purpose of this study was to use magnetic resonance angiography (MRA) to clarify the inguinal anatomy and provide a reliable method for identifying the location of the superficial transverse inguinal lymph nodes. In this study MRA was used to evaluate the superficial inguinal lymph nodes in 117 patients. Coordinates of lymph nodes were plotted relative to an axis from the anterior superior iliac spine (ASIS) to the pubic tubercle (PT). The nodes were also plotted relative to the superficial circumflex iliac vein (SCIV) and superficial inferior epigastric vein (SIEV). A total of 1,938 lymph nodes were identified. These lymph nodes were concentrated on one-third the distance from the PT toward the ASIS and 3 cm perpendicularly below this line. About 67% of the superficial inguinal nodes were located within the bifurcation of the SIEV and SCIV. The results from this study provide useful guidelines for locating lymph nodes targeted for VGLNT.

RESUMEN

INTRODUCTION: Patients with node positive or locally advanced breast cancer desiring deep inferior epigastric perforator (DIEP) flap reconstruction frequently require postmastectomy radiation therapy (PMRT). To avoid the deleterious effects of PMRT, surgeons will often delay reconstruction until after PMRT is complete. Drawbacks to this approach include additional surgery, recuperation, cost, and an extended reconstructive process. Even if a tissue expander is used to preserve the skin envelope during irradiation, the post-PMRT breast pocket is often distorted or constricted necessitating some skin replacement, resulting in a compromised aesthetic outcome. Therefore, a systematic approach to mitigate the deleterious effects of PMRT was developed, and primary DIEP flap reconstruction was offered to patients requiring PMRT. This study evaluates the outcome of this approach in a cohort of patients undergoing immediate bilateral DIEP flap reconstruction with unilateral PMRT, allowing comparison between irradiated and nonirradiated flaps. METHODS: One hundred twenty-five patients who underwent immediate DIEP reconstruction between 2009 and 2011 were identified. Eleven consecutive patients had bilateral DIEP reconstructions by a single surgeon and received unilateral PMRT. Preoperative, intraoperative, and postoperative steps were taken in all patients to ensure flap vascularity, prevent uncontrolled contracture, and limit radiation damage to the breast mound. Results were documented photographically and the irradiated and nonirradiated breasts were compared. The complication rates, incidence of clinically significant fat necrosis, and need for reoperation were examined. RESULTS: Median follow-up was 18 months (range, 8-21 months). Complications were minor and did not require readmission to the hospital or reoperation. There was no incidence of clinically significant fat necrosis in either the irradiated or nonirradiated DIEP flaps. Four operative revisions for breast symmetry were required in 3 of 11 patients. Aesthetic outcomes were deemed satisfactory in all patients. CONCLUSIONS: Primary reconstruction with DIEP flaps can be performed successfully in patients who require PMRT if steps are taken to ensure flap vascularity, minimize fibrosis, optimize contour, and modulate radiation dosing.

RESUMEN

Background: Hyaluronic acid (HA) filler injections for facial augmentation are commonly administered but can lead to post-hyaluronic acid recurrent eyelid edema (PHAREE). The pathophysiology of this condition has not been fully understood. Objectives: To report the successful treatment of PHAREE using serial hyaluronidase and fractionated radiofrequency microneedling, with additional carbon dioxide laser skin resurfacing in selected patients. Methods: Five patients with PHAREE were treated with serial hyaluronidase injections and fractionated radiofrequency microneedling, with 2 patients receiving carbon dioxide laser treatment. The patients were followed up for a minimum of 24 months. Results: All patients reported a resolution of PHAREE signs/symptoms with no adverse effects or recurrence. One patient demonstrated complete resolution after a single treatment; 4 required a series of treatments. Conclusions: The proposed treatment protocol may provide advantages over hyaluronidase alone for PHAREE. The impermeable malar septum, vulnerable eyelid lymphatics, and potential immunogenicity of HA fragments likely contribute to PHAREE pathophysiology. Further research on pathophysiologic mechanisms is warranted.

RESUMEN

Radiofrequency is an effective and safe method for both pelvic floor restoration and nonsurgical labiaplasty. Bipolar radiofrequency with temperature control is more effective than monopolar radiofrequency for volumetric heating of vulvovaginal tissue. Combination of electrical muscle stimulation and radiofrequency can provide combined nonsurgical restoration of the vulvovaginal tissues.

RESUMEN

Background: The use of radiofrequency in aesthetic surgery has evolved significantly since it was first introduced in the early 2000s. Nonexcisional correction of the lower one-third of the face and neck has long been a challenging problem. The purpose of this prospective study was to assess the safety and efficacy of the first handsfree thermoregulated bipolar radiofrequency device for face and neck contouring. Methods: This prospective multicenter (New York, Nevada) IRB-approved study evaluated healthy candidates who desired noninvasive correction of their lower face and neck laxity. The primary objective of this study was to evaluate safety and soft tissue remodeling pretreatment and at 1-, 3-, and 6-months post last treatment. Assessment was made using blinded evaluators, 3D photographic analysis (Quantificare, France), and volumetric measurements. Investigator and subject assessments were obtained using a 0-4 point Likert scale. Results: A total of 34 patients completed both the cheek and chin applicator treatment series. Average age of patients was 38 (STD 3.4), BMI 27 (STD 2.2), average Baker Face & Neck classification 2.6 (STD 1.1), and average Fitzpatrick type 2.4 (STD 1.2). Mean treatment time was 41 min (STD 3.5) with a temperature of 42°C-43°C. Patient discomfort data were statistically very low based on t-test analysis. Satisfaction metrics measured at 1- and 3-month follow-up demonstrated a significant change in subject skin appearance, subject overall satisfaction, and investigator improvement perception. More patients were satisfied at the 3-month follow-up compared with the 1-month follow-up for all three measures. Volumetric data demonstrated an average change of -3.2 cm3 (STD ±1.2 cm3) per side for the cheek applicator and -4.1 (STD ±2.3) for the submental applicator. Of note there were cases where volume increases were noted that were believed to be related to soft tissue contraction. Conclusions: This is the first prospective study to evaluate a handsfree thermoregulated bipolar radiofrequency device for face and neck contouring. This device demonstrates a significant advance in the control and delivery of radiofrequency for aesthetic purposes. With a favorable safety and comfort profile, this device is able to concentrate thermal energy consistently at a depth that allows for fibroseptal network tightening to improve lower third of face and submental soft tissue contraction.

RESUMEN

INTRODUCTION: Patients desiring noninvasive body contouring increasing require a more comprehensive approach to soft tissue laxity, muscle, and adipose hypertrophy. Previous devices have typically focused on only adipose reduction, without impact on muscle or skin laxity. This study describes the first use of noninvasive bipolar radiofrequency in combination with electromagnetic muscle stimulation. METHODS: This study was an IRB-approved study conducted at four sites (TN, TX, PA, NC). In all, 38 patients completed the three-treatment regimen of combined non-invasive bipolar RF and EMS. Efficacy of the Transform (InMode, Lake Forest, CA) treatment was assessed by numerous outcomes including sequential caliper measurements, circumference measurements, comfort during treatment, subject satisfaction, ultrasound measurements, blinded pictures evaluation, and histology. RESULTS: The combination of non-invasive bipolar RF with EMS was found to be safe and efficacious. The three-treatment regimen was statistically efficacious as it related to (1) subject satisfaction, (2) 1 mm ultrasound, (3) 2 mm ultrasound, (4) average of 1 and 2 mm ultrasound, (5) caliper 1 measurements, (6) caliper 2 measurements, (7) average of caliper 1 and 2 measurements, (8) subject comfort, (9) widest circumference measure, (10) 2-inches above circumference measure, (11) 2-inches below circumference measure, (12) average circumference measure, and finally, (13) blinded evaluator photograph agreement. CONCLUSION: The combination of noninvasive bipolar radiofrequency and electrical muscle stimulation is a safe and effective method for treatment of skin laxity, adipose hypertrophy, and muscle.

RESUMEN

Labiaplasty has rapidly increased in popularity over the past 5 years.Traditional labiaplasty is associated with potential complications, such as dehiscence, hematoma, flap necrosis, narrowed introitus, pain, and asymmetry. Minimally invasive techniques such as radiofrequency (RF) have emerged as viable alternatives to traditional labiaplasty through a temperature-controlled bipolar mechanism to heat tissues to target temperatures of 40°C-45°C. This controlled energy delivery leads to an inflammatory cascade initiating neocollagenesis, angiogenesis, and elastogenesis over the coming 3-4 months. A single surgeon series of labia minora and majora treatment by RF (InMode, Lake Forrest, Calif.) was reviewed between April 2018-October 2018. Demographic data were collected as well grade of hypertrophy (pre/posttreatment), number of vaginal deliveries, and reason for treatment. Procedural parameters were recorded, including internal/external temperatures, total energy used, and time of treatment. All adverse events were recorded. Objective and subjective data points were obtained in the form of patient surveys and photographic evaluation by lay persons as well as plastic surgeons objective to the treatment. Ten consecutive patients were treated with bipolar RF (InMode, Lake Forrest, Calif.) between April 2018-October 2018. Mean age was 44 (29-54). Average number of pregnancies was 2 (STD 1.1). Three patients were treated for aesthetic concerns, 3 for functional complaints, and 4 desired improvement in both. Overall graded improvement in labia size/contour was +50% (STD ±15.3). Patient satisfaction scale data demonstrated 9.5/10 (±1.7). All patients (10/10) stated that they would undergo treatment again. In all cases, the surgeon observed tightening of the clitoral hood, introitus, forchett, as well as improved distribution of dark pigmentation of the labia minora. There were no significant complications and no need for additional procedures. Average recovery time was 14 days (STD 2.2). Treatment of labia hyperplasia and laxity with bipolar RF may potentially fill a treatment gap of women seeking aesthetic and functional improvements without surgical labiaplasty. A powered prospective randomized double-blinded study is needed to further elucidate the role of this technology.
