Medium- and Long-Term Outcomes of Autologous Fat Grafting to Hands and Feet for Patients With Raynaud Phenomenon.

BACKGROUND: Autologous fat grafting (AFG) has emerged as a promising treatment option for Raynaud phenomenon. However, existing studies are limited by short follow-up, and there is little evidence regarding predictive factors for successful outcomes. METHODS: A retrospective chart review and standardized phone interviews were performed for all patients (n = 17, 65% response rate) treated with AFG to the hands or feet at our institution for primary or secondary Raynaud from 2010 to 2021. Each occurrence of AFG was defined as a separate surgery (n = 23), with an average follow-up of 3.7 years. RESULTS: At follow-up, patients reported a 31% reduction in cold attack frequency, a 45% reduction in the intensity of individual attacks, a 29% reduction in the duration of attacks, and a 40% improvement in overall Raynaud Condition Score (P < 0.01). Although initial AFG to an extremity significantly improved symptoms, subsequent attempts were not shown to statistically improve outcomes. Digital ulcers were present in 65% of cases, and AFG resulted in ulcer healing in 87% of those cases. Median duration of maximum symptom relief was 1 year postoperatively, with 74% of patients reporting diminishing symptom relief by 4 years postoperatively. Those with a BMI ≥25, with primary Raynaud phenomenon or without preoperative ulcers experienced significantly longer symptom relief (P < 0.05). Average patient satisfaction was 7.7 of 10, and 91% would recommend the procedure to others. CONCLUSIONS: Autologous fat grafting is an effective, albeit sometimes temporary, treatment for Raynaud and digital ulcers. Certain patients may be more likely to experience lasting symptom relief beyond 1 year.

Beyond the Breast: Body Contouring in the Context of Abdominally Based Microsurgical Breast Reconstruction.

With continued advances in abdominally based microsurgical breast reconstruction, the operative goal is no longer the creation of a simple breast mound but rather the formation of an aesthetically pleasing breast. While a substantial body of work has been dedicated to accomplishing this result, a similar progression has yet to be reflected in the literature with regard to the contour and shape of the abdominal donor site. Operative advances including muscle, fascial, and nerve preservation have been effective in minimizing the physiologic donor site morbidity of this procedure but have focused less on its cosmesis. Additionally, the published techniques aimed at the aesthetics of the abdomen have focused on the initial procedure and have not utilized the multistage process of breast reconstruction. In this paper, we will describe our approach to optimize the aesthetic result of the abdomen in abdominally based microsurgical breast reconstruction.

Branding a Plastic Surgery Group Practice: A Case Study.

BACKGROUND: You only get one opportunity to make a first impression. In today's era, that first impression is frequently a digital one. The authors' old digital brand "face" was stale and not a true representation of how they view themselves as a practice. In an evolving arena of competition and surgical scope, the authors felt compelled to engage in rebranding their practice. METHODS: This article details the steps the authors took to launch a new website, generate collateral branded material, and execute a social media marketing plan. The authors attempt to keep the outline general enough to be applicable to the range of practice types of the Journal 's readership, and present relevant results of the process. RESULTS: Samples of "creative" products are shown. Quantifiable outcomes were direct website traffic (91% increase), website sessions (82% increase), unique users (55% increase), page views (118% increase), and time spent browsing (100% increase). The authors experienced a 21% increase in new patient volume and a similar increase in total cases performed. CONCLUSIONS: This article outlines steps the authors took to rebrand their practice in the face of current challenges in the plastic surgery landscape and how prospective patients seek surgeons. Benchmarking the steps of a successful branding process is crucial and informative to developing and executing a plan. Although there are many potential contributors to the growth of a practice, the impact of our branding appears to be a significant factor.

Post-Breast Surgery Pain Syndrome: Shifting a Surgical Paradigm.

Post-mastectomy pain syndrome and the less well-described post-breast surgery pain syndrome are long-term neuropathic pain conditions that may affect more than 50% of patients after mastectomy and breast surgery. While the etiology, risk factors, and management have been reviewed in our literature, we offer here a focused outline that will gear the plastic surgeon with tools to lead a multidisciplinary, algorithmic approach to the care of patients with post-mastectomy pain syndrome/post-breast surgery pain syndrome. After reading this article, we hope the reader will have improved awareness of post-mastectomy pain syndrome/post-breast surgery pain syndrome, and thus be able to incorporate appropriate treatments and preventative steps into their primary surgical routine.

Incidence, Impact, and Management of Incidentalomas on Preoperative Computed Tomographic Angiograms for Breast Cancer Patients with and without Genetic Mutations.

BACKGROUND: Preoperative abdominal computed tomographic angiograms for free flap breast reconstruction improve operative safety and efficiency, but incidental findings are common and potentially affect management. In addition, the authors hypothesized that patients with genetic mutations might have a higher rate of significant findings. The authors present the largest series of computed tomographic angiogram "incidentalomas" in these two populations and an evidence-based algorithm for managing common findings. METHODS: All patients undergoing free flap breast reconstruction at Northwell Health between 2009 and 2017 were eligible. Medical history, perioperative details, and radiology reports were examined with abnormal findings recorded. Published literature was reviewed with radiologists to develop standardized guidelines for incidentaloma management. RESULTS: Of 805 patients included, 733 patients had abdominal imaging. One hundred ninety-five (27 percent) had a completely negative examination. In the remaining 538 patients, benign hepatic (22 percent) and renal (17 percent) findings were most common. Sixteen patients (2.2 percent) required additional imaging (n = 15) or procedures (n = 5). One finding was concerning for malignancy-renal cell carcinoma-which interventional radiology ablated postoperatively. Seventy-nine patients (10.8 percent) had a genetic mutation but were not found to have a statistically significant higher rate of incidentalomas. CONCLUSIONS: The authors' rate of computed tomographic angiography incidental findings (73 percent) is consistent with previous studies, but the rate requiring further intervention (2.2 percent) is lower. Incidental findings were no more common or pathologic among genetic mutation carriers. The authors also introduce an evidence-based algorithm for the management of common incidentalomas. Using these guidelines, plastic surgeons can reassure patients, regardless of mutation status, that incidentalomas are most commonly benign and have minimal impact on their surgical plan.

Umbilical Ablation During Deep Inferior Epigastric Perforator Flap Harvest Decreases Donor Site Complications.

BACKGROUND: Donor site complications are a significant source of morbidity for patients undergoing abdominal-based free flap breast reconstruction, but there is a paucity of data regarding minimizing these postoperative complications. We hypothesize that selective ablation of the umbilicus at the time of deep inferior epigastric perforator (DIEP) harvest decreases the incidence of umbilical and abdominal wall complications in high-risk patients. METHODS: A retrospective review was performed of all patients (n = 117) who underwent DIEP harvest with concomitant umbilical ablation from 2010 to 2015. This cohort was paired with 117 patients who underwent DIEP harvest without umbilical ablation. Preoperative risk factors, intraoperative factors, and postoperative complications were compared. RESULTS: The umbilical ablation group had significantly higher body mass index (30.9 vs 27.4 kg/m, P < 0.001), presence of umbilical scar (20.9% vs 5.3%, P < 0.001), umbilical hernia (82.9% vs 8.5% P < 0.001), ventral hernia (23.9% vs 1.7%, P < 0.001), and rectus diastasis (10.3% vs 2.6%, P = 0.016). There were no significant differences of smoking, diabetes mellitus, hypertension, prior abdominal surgery, or midline abdominal scar. The umbilical ablation group had a significantly lower rate of postoperative abdominal wound dehiscence and skin loss (11.1% vs 22.2%, P = 0.023) and overall donor site complications (24.8% vs 39.3%, P = 0.017). There was no significant difference in incidence of cellulitis, seroma, or abscess. Mean follow-up time was 1.8 years. CONCLUSIONS: Selective umbilical ablation in high-risk patients at the time of abdominal flap harvest can result in significantly fewer donor site wound complications, even in the setting of increased risk factors for poor wound healing. This is likely due to avoidance of umbilical incisions and decreased upper abdominal skin undermining. We conclude that umbilical ablation is a viable option to minimize donor site complications, especially in high-risk patients.

Gene expression analysis and microdialysis suggest hypothalamic triiodothyronine (T3) gates daily torpor in Djungarian hamsters (Phodopus sungorus).

Thyroid hormones play an important role in regulating seasonal adaptations of mammals. Several studies suggested that reduced availability of 3,3',5-triiodothyronine (T3) in the hypothalamus is required for the physiological adaptation to winter in Djungarian hamsters. We have previously shown that T3 is involved in the regulation of daily torpor, but it remains unclear, whether T3 affects torpor by central or peripheral mechanisms. To determine the effect of T3 concentrations within the hypothalamus in regulating daily torpor, we tested the hypothesis that low hypothalamic T3 metabolism would favour torpor and high T3 concentrations would not. In experiment 1 gene expression in torpid hamsters was assessed for transporters carrying thyroid hormones between cerebrospinal fluid and hypothalamic cells and for deiodinases enzymes, activating or inactivating T3 within hypothalamic cells. Gene expression analysis suggests reduced T3 in hypothalamic cells during torpor. In experiment 2, hypothalamic T3 concentrations were altered via microdialysis and torpor behaviour was continuously monitored by implanted body temperature transmitters. Increased T3 concentrations in the hypothalamus reduced expression of torpor as well as torpor bout duration and depth. Subsequent analysis of gene expression in the ependymal layer of the third ventricle showed clear up-regulation of T3 inactivating deiodinase 3 but no changes in several other genes related to photoperiodic adaptations in hamsters. Finally, serum analysis revealed that increased total T3 serum concentrations were not necessary to inhibit torpor expression. Taken together, our results are consistent with the hypothesis that T3 availability within the hypothalamus significantly contributes to the regulation of daily torpor via a central pathway.

Distant blunt forceps dissection in tissue expander insertion: A novel technique.

Tissue expansion using implantable expanders is a useful means of generating surplus tissue for reconstruction of defects such as scarring following burns. The authors describe their technique of incisions distant to the desired location of expander placement, and remote dissection of the expander pocket with hydrodissection and blunt forceps. A total of 81 expanders were placed in 30 consecutive patients, 81% of whom had burn scars due for reconstruction. During preparation, no complications, such as bleeding, were encountered, except one case with severe subdermal fibrosis, in which bleeding was stopped through brief application of pressure. Postoperatively, no complications were encountered in 76% of patients; however, 16.6% exhibited surgical site infection, which was managed conservatively and was correlated with a high number of expanders implanted at once. One patient experienced hematoma formation that resolved spontaneously, and one instance of expander extrusion and subsequent removal occurred. Receiving ≥2 expanders at the same time was statistically associated with higher risk for complication(s). The authors' complication rates were moderate and comparable with open or endoscopic approaches. Time of expansion is reduced compared with the open approach due to distant incision placement and immediate usability. Cost effectiveness appeared to be better using only inexpensive forceps, rather than elaborate and costly endoscopic equipment.

L'expansion tissulaire à l'aide d'implants produit un excédent de tissus utile pour reconstruire des lésions telles que des cicatrices consécutives à des brûlures. Les auteurs décrivent leur technique d'incisions éloignées du foyer de l'expanseur et leur méthode d'hydrodissection par pinces mousse à distance de la poche d'expanseur. Au total, ils ont inséré 81 expanseurs chez 30 patients consécutifs, dont 81 % pour reconstruire des cicatrices consécutives à des brûlures. Pendant la préparation, les chercheurs n'ont relevé aucune complication, telle qu'une hémorragie, à part un cas d'importante fibrose sous-cutanée dont l'hémorragie a été interrompue par une brève pression. Après l'opération, ils n'ont observé aucune complication chez 76 % des patients, mais 16,6 % ont présenté une infection au site chirurgical, liée à l'implantation de plusieurs expanseurs en une même intervention et traitée avec prudence. Un patient a présenté un hématome qui s'est résolu spontanément, et un autre, une extrusion de l'expanseur qu'il a fallu retirer. L'implantation simultanée d'au moins deux expanseurs s'associait statistiquement à un risque plus marqué de complication(s). Le taux de complications des auteurs était modéré et comparable à celui des chirurgies ouvertes ou des endoscopies. L'expansion était de plus courte durée que par chirurgie ouverte, grâce à l'incision à distance et à l'utilisabilité immédiate. Le rapport coût-efficacité semblait supérieur au moyen de pinces bon marché que de matériel endoscopique élaboré et coûteux.

The Chemistry of Cold: Mechanisms of Torpor Regulation in the Siberian Hamster.

Siberian hamsters use spontaneous daily torpor, a state of hypometabolism and hypothermia, to save energy during winter. Multiple neuroendocrine signals set the scene for spontaneous torpor to occur, and several brain areas have been identified as potential sites for torpor regulation. Here, we summarize the known mechanisms of a fascinating physiological state in the Siberian hamster.

Superficial Inferior Epigastric Artery: Learning Curve versus Reality.

BACKGROUND: Breast reconstruction with the superficial inferior epigastric artery (SIEA) free flap continues to gain popularity among reconstructive surgeons. The low risk for abdominal wall morbidity must be weighed against the higher concern for thrombotic events. The aim of this study was to review the authors' recent experience with the SIEA flap and investigate whether their previously published incidences of vessel thrombosis and flap loss were related to their own "learning curve" or whether these adverse events are attributable to inherent qualities of the SIEA flap. METHODS: The authors performed a retrospective chart review of all patients undergoing SIEA flap surgery between January 1, 2008, and July 1, 2014, at their institution. All included operations were performed by the senior author (J.M.S.). The main outcomes of interest included vessel thrombosis and partial/full flap loss. RESULTS: Forty-seven SIEA flaps were performed on 39 patients. Sixty-four percent (n = 30) were immediate reconstructions and 79 percent (n = 37) were bilateral. There were five intraoperative arterial thromboses (10.6 percent) and one intraoperative venous thrombosis (2.1 percent), with eight total thrombotic events (17.0 percent). One total flap loss (2.1 percent) and two partial flap losses (4.3 percent) were experienced. CONCLUSIONS: The authors' recent experience with SIEA-based breast reconstruction shows a similar incidence of thrombotic events and flap loss compared with the authors' early experience. These incidences remain greater than what is seen with other abdominally based autologous breast reconstruction techniques and do not appear to be attributable to an operator learning curve. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Torpor expression in juvenile and adult Djungarian hamsters (Phodopus sungorus) differs in frequency, duration and onset in response to a daily cycle in ambient temperature.

In addition to morphological and physiological traits of short-day acclimatisation, Djungarian hamsters (Phodopus sungorus) from Central Asia exhibit spontaneous daily torpor to decrease energy demands during winter. Environmental factors such as food scarcity and low temperatures have been shown to facilitate the use of this temporal reduction in metabolism and body temperature. We investigated the effect of a daily cycle in ambient temperature on short-day acclimation and torpor expression in juvenile and adult Djungarian hamsters. The animals were exposed to a cold dark phase (6°C) and a warmer light phase (18°C) and were compared with control hamsters kept at a constant ambient temperature of 18°C. Under constant conditions, torpor expression did not differ between adult and juvenile hamsters. Although the daily temperature cycle evoked an increased metabolic rate in adult and juvenile hamsters during the dark phase and strengthened the synchronization between torpor entrance and the beginning of the light phase, it did not induce the expected torpor facilitation. In adult hamsters, torpor expression profiles did not differ from those under constant conditions at all. In contrast, juvenile hamsters showed a delayed onset of torpor season, a decreased torpor frequency, depth and duration, as well as an increased number of early torpor terminations coinciding with the rise in ambient temperature after the beginning of the light phase. While the temperature challenge appeared to be of minor importance for energy balance and torpor expression in adult hamsters, it profoundly influenced the overall energy saving strategy of juvenile hamsters, promoting torpor-alleviating active foragers over torpor-prone energy-savers. In addition, our data suggest a more efficient acclimation in juvenile hamsters under additional energy challenges, which reduces the need for torpor expression.

Thyroid hormone status affects expression of daily torpor and gene transcription in Djungarian hamsters (Phodopus sungorus).

Thyroid hormones (TH) play a key role in regulation of seasonal as well as acute changes in metabolism. Djungarian hamsters (Phodopus sungorus) adapt to winter by multiple changes in behaviour and physiology including spontaneous daily torpor, a state of hypometabolism and hypothermia. We investigated effects of systemic TH administration and ablation on the torpor behaviour in Djungarian hamsters adapted to short photoperiod. Hyperthyroidism was induced by giving T4 or T3 and hypothyroidism by giving methimazole (MMI) and sodium perchlorate via drinking water. T3 treatment increased water, food intake and body mass, whereas MMI had the opposite effect. Continuous recording of body temperature revealed that low T3 serum concentrations increased torpor incidence, lowered Tb and duration, whereas high T3 serum concentrations inhibited torpor expression. Gene expression of deiodinases (dio) and uncoupling proteins (ucp) were analysed by qPCR in hypothalamus, brown adipose tissue (BAT) and skeletal muscle. Expression of dio2, the enzyme generating T3 by deiodination of T4, and ucps, involved in thermoregulation, indicated a tissue specific response to treatment. Torpor per se decreased dio2 expression irrespective of treatment or tissue, suggesting low intracellular T3 concentrations during torpor. Down regulation of ucp1 and ucp3 during torpor might be a factor for the inhibition of BAT thermogenesis. Hypothalamic gene expression of neuropeptide Y, propopiomelanocortin and somatostatin, involved in feeding behaviour and energy balance, were not affected by treatment. Taken together our data indicate a strong effect of thyroid hormones on torpor, suggesting that lowered intracellular T3 concentrations in peripheral tissues promote torpor.

Modification of the Labbé Procedure: Integration of the Deep Temporalis Fascia Turnover Flap.

Modification of the lengthening temporalis myoplasty for reanimation of facial paralysis is presented. A patient experienced traumatic laceration of the left facial nerve resulting in left hemifacial paralysis. Multiple attempts at nerve repair were unsuccessful. For smile restoration, a Labbé procedure was performed. Because of inadequate length, the temporalis tendon could not be directly secured to the modiolus. Therefore, an inferiorly based temporalis fascia flap was recruited from the deep temporal fascia and reflected inferiorly to provide additional length by which the tendon could be secured to the modiolus. This technique provided immediate smile restoration and required no additional donor site.

Use of thoracodorsal artery perforator flaps to enhance outcomes in alloplastic breast reconstruction.

BACKGROUND: Use of the thoracodorsal artery perforator (TDAP) flap in combination with alloplastic devices has been proven to be a safe method of breast reconstruction. However, preoperative irradiation increases the complication rate and thus some consider preoperative radiotherapy a relative contraindication to alloplastic alone reconstruction. We evaluated the long-term outcomes of patients with preoperative radiotherapy who had delayed alloplastic reconstruction with a TDAP flap. METHODS: A retrospective analysis of a prospectively maintained database was performed to identify patients who had received a Latissimus Dorsi (LD), a Muscle Sparing Latissimus Dorsi (MSLD), or a TDAP flap plus a tissue expander or implant between 2005 and 2012. Information regarding patients' primary diagnosis, radiation history, prior breast reconstructions, and complications was collected and analyzed. RESULTS: Sixteen patients who had a total of 16 breast reconstructions with an LD (6) or TDAP/MSLD1 flap (10). Demographic data, device type, co-morbidities and complications were analyzed. The rate of capsular contracture and size asymmetry were higher in the LD group, but there was no difference noted for major complications. Minor complications were also similar between the 2 groups. CONCLUSIONS: Patients who underwent irradiation before TDAP flap did not have a higher complication rate when compared with patients who had a full LD flap following radiation. By integrating well-vascularized, nonradiated tissue of a TDAP flap in reconstruction, overall complication rate may be minimized and the results are comparable to the generally accepted method of utilizing the entire latissimus dorsi muscle.

Prelaminated fascia lata free flap for large nasal septal defect reconstruction.

Nasal septal defects can be challenging to repair, given their location, size, and the unique, tri-layered structure of the septum, which includes a thin piece of cartilage positioned between mucosal layers. The report herein presents a case of a 47 year-old woman with a large symptomatic nasal septal perforation, despite saline irrigations and ointment. Placement of a septal button or a traditional surgical approach was not considered because of the extremely large nature of the perforation. We describe the use of a tri-layered fascia lata flap prelaminated with buccal mucosa grafts to successfully repair this complicated defect. Subsequent follow-up visits showed complete repair of the defect and patent nasal passages, without the need for any debulking procedures. Based on these results, we conclude that a prelaminated fascia lata flap is a good reconstructive option for large, complex nasal septal defects, bringing thin, healthy mucosalized tissue to the defect and minimizing future surgical procedures.
