A 1-Day-Old Girl With Infantile Hemangioma and Sternal Cleft.

CASE PRESENTATION: A newborn girl presented to the hospital on the first day of life because of respiratory failure. She was born at home at 37 weeks' gestation with minimal prenatal care and was found to be small for gestational age. The patient was found to have partial sternal agenesis and sternal cleft, cutis aplasia, left facial hemangioma, micrognathia, wide-spaced nipples, and low-set ears. The mother's and baby's urine toxicology screening were positive for amphetamines. Chest radiographs on admission showed bilateral hazy opacities. CT scan of the chest showed an absent sternum with midline chest wall concavity. The patient was monitored preoperatively in the cardiac ICU for risks of arrythmia, respiratory failure, altered cardiac output, and acute cardiopulmonary decompensation.

Keloid Intralesional Excision Reduces Recurrence: A Meta-analytic Study of the Available Literature on 608 Keloids.

Background: The objective of this meta-analysis was to examine the effectiveness of keloid intralesional excision (KILE) in preventing recurrence. Treatment of keloids using surgical excision alone leads to high rates of recurrence. To date, there are no widely accepted guidelines for keloid treatment, and a multitude of adjunctive therapies are used to reduce recurrence. Despite these efforts, recurrence remains high. In this study, we conducted a meta-analysis of the existing literature on KILE to determine its role in recurrence reduction. Methods: A literature review using PubMed, Scopus, and Web of Science databases was performed. Two authors independently evaluated studies for eligibility. Incidence of keloid recurrence was recorded, and a comprehensive meta-analysis was performed to assess the pooled keloid recurrence rate, as well as the effect of additional therapies. Results: Twenty-two studies evaluating intralesional excision of 608 keloids were included in the study. Average time to follow-up was 19.2 months (range 6-35 months). A meta-analysis of proportions was conducted, demonstrating a pooled recurrence rate of 13% (95% confidence interval, 9%-16%). There was no evidence that using therapies in addition to KILE had a significant effect on the overall pooled recurrence rate. Conclusions: A meta-analysis of 608 keloids shows that KILE is an effective technique in preventing keloid recurrence, with a pooled recurrence rate of 13% compared with previously reported rates of 45%-100% after complete excision. Although there are no standard guidelines for keloid treatment, our meta-analysis shows that KILE is promising in recurrence reduction.

Characterization of Auricular Growth within the Pediatric Population Using Computed Tomography Scan Measurements.

Background: In patients with microtia, auricular reconstruction is ideally performed promptly to prevent impaired socialization during formative childhood years. The earliest viable age for reconstruction is widely accepted from 7-10 years of age, as full auricular size is achieved around age 8, with some variability dependent on sex. This retrospective study aims to provide an auricular growth curve that accounts for age and sex, enhancing the individualized approach to ear reconstruction. Methods: A total of 319 images of unaffected patients who underwent computed tomography angiography of the head and neck were reviewed, with bilateral cartilage height and width measured according to a consensus-standardized image measurement protocol. Means and SDs of cartilage height and width were calculated for both sexes, and analysis of ear growth was performed through plotting the mean cartilage height, width, and width:height ratio over time. Results: Cartilage height and width differed significantly between male and female groups. Maximum cartilage height was reached at age 11 for female and at age 12 for male patients, whereas maximum cartilage width was reached at ages 10 and 8, respectively. On average, the width:height ratio for female group was 0.58. For male group, the average width:height ratio was 0.59. Conclusions: An auricular growth map was designed using computed tomography measurements demonstrating maximum auricular size at age 11 and 12 respectively for female and male patients, with both sexes having a width:height ratio maintained at approximately 0.6 throughout growth.

Surgical approach to penile reconstruction for shaft skin excision from circumcision.

PURPOSE: Circumcision is one of the most frequently performed surgical procedures. Complications are infrequent, including bleeding, though can be significant such as shaft skin excision. The aim of this study was to identify mechanism of injury and reconstructive techniques for skin excision using a full thickness skin graft (FTSG) or with the novel application of tissue expanders (TE). METHODS: Patients who underwent penile reconstruction following shaft skin excision from an overzealous circumcision were retrospectively reviewed. The penis was covered using a FTSG, harvested from the groin/hip, or using TE, with expanders placed in residual shaft skin. RESULTS: Twelve patients experienced significant skin loss (range 65-95%) including 2 with partial glans loss. Ten were reconstructed using a FTSG and 2 with TE. Injury was most frequently from a Mogen clamp (n = 9), or from a Gomco clamp, Plastibell device, and electrocautery burns. Six FTSG patients experienced complications with lymphedema (n = 3) most common. CONCLUSION: Shaft skin excision is a devastating complication with risk greatest from Mogen clamp use. TE is preferred as this avoids donor site morbidity which reassures parents but requires sufficient residual skin that can be expanded. Both techniques effectively provide soft tissue coverage with acceptable appearance and long-term function.

Sexual health outcomes after penile reconstruction in the exstrophy-epispadias complex.

INTRODUCTION: The penis in exstrophy-epispadias complex (EEC) males is diminutive and patients are often dissatisfied with appearance and length. Due to an increased risk of psychosexual dysfunction, patients desire penile reconstruction. Surgical options include penile lengthening with a full thickness skin graft (SG) or tissue expansion (TE) used for cutaneous coverage or neophalloplasty using a radial forearm free flap or pedicled antero-lateral thigh flap. OBJECTIVE: The aim of this study was to assess sexual health outcomes before and after SG or TE assisted lengthening and neophalloplasty. STUDY DESIGN: Patients aged 18 years or older, who underwent penile reconstruction were identified using an institutionally approved database of EEC patients. Patient perception of penile appearance, sexual function, their frequency of sexual intercourse and overall satisfaction with reconstruction were assessed using a survey consisting of validated and non-validated questions. RESULTS: Eighty-three patients underwent penile reconstruction, 57 met the inclusion criteria and 28 responded to the survey (49.1%). Fourteen were reconstructed using a SG, 6 with TE and 8 underwent neophalloplasty. Median time from reconstruction to survey completion was 4.4 years (range 1.2-13.2) Four patients had a diagnosis of epispadias, 1 cloacal exstrophy, 23 classic bladder exstrophy (CBE). Before reconstruction patients were dissatisfied with their penile appearance with a median penile perception score of 4.5 compared to 7.5 after surgery (p = 0.0034, Fig. 1). Twenty-three patients were dissatisfied with penile length, with 18 reporting an improvement following reconstruction (p = 0.0002). There was no correlation in time after reconstruction with PPS or satisfaction with penile length (p = 0.86 and p = 0.55, respectively). Overall, the median Sexual Health Inventory for Men (SHIM) score was 19, with no difference between the surgical groups (p = 0.33). Nine patients engaged in sexual intercourse before reconstruction which increased to 17 afterwards. CONCLUSION: All three surgical methods improved patient perception of penile appearance and length. Patients who previously never engaged in intercourse were able to and those who had were doing so more frequently, of which a greater proportion were in a relationship. The results are encouraging though must be interpreted with caution due to the small number of responders and possible risk of bias. These findings provide vital information for future patients and routine psychological assessment will help manage patient expectations to improve satisfaction.

Pindborg tumor in early childhood: a rare tumor in the youngest patient reported to date.

Pindborg tumor is a benign expansile and slow growing odontogenic tumor that occurs mainly in adulthood. Limited management data exist for its treatment in young patients. We report the case of a 5-year-old patient and provide recommendations for the care of pediatric patients diagnosed with this rare odontogenic tumor.

Sensate total clitoris reconstruction via microneurovascular dorsal foot web space flap with pudendal nerve coaptation.

Revision surgery after gender-affirming genitoplasty is becoming more and more common as more patients gain access to surgical treatment. The complexity of genitoplasty and extensive dissection of delicate tissues predisposes patients to necrosis of the flap(s) employed, which can leave patients with complications ranging from poor aesthetics to total lack of genital sensation. The purpose of this report is to detail the revision surgery of a 32-year-old transgender woman who underwent vaginoplasty at an outside institution and presented to our clinic for clitoral reconstruction following necrosis and near-total loss of the neoclitoris. Physical exam showed extensive necrosis, and 3-Tesla magnetic resonance (MRI) revealed significant scarring of the pudendal nerve branches at the level of the pubic symphysis. Healthy nerve was identified at the level of the right inferior pubic ramus, and total clitoral reconstruction with an innervated first dorsal web space free flap anastamosed to the deep inferior epigastric vessels was performed. Complications included donor site cellulitis with partial loss of the skin graft and formation of hypertrophic scar tissue. This was treated 6 months postoperatively with excision of scar tissue in the webspace and placement of an additional full-thickness skin graft. At follow-up, the patient reported tactile and erogenous sensation of the neoclitoris itself and subjective satisfaction with the aesthetic outcome. Our results provide evidence that this flap is a feasible option to create an aesthetic and sensate neoclitoris in the setting of previous neoclitoral necrosis. This case report also describes the novel use of 3-Tesla MRI in target selection for nerve coaptation.

Pedicled Anterolateral Thigh and Radial Forearm Free Flap Phalloplasty for Penile Reconstruction in Patients With Bladder Exstrophy.

PURPOSE: Male patients with exstrophy-epispadias complex have a congenitally short penis. Adolescent and adult patients often desire penile reconstruction to enable penetrative intercourse. When penile lengthening using local tissue and/or skin graft is unsuitable, phalloplasty is performed. We provide updated experiences using radial forearm free flap and pedicled anterolateral thigh flap phalloplasty techniques over a 6-year period in exstrophy-epispadias complex patients. MATERIALS AND METHODS: Consecutive patients who underwent radial forearm free flap or pedicled anterolateral thigh flap phalloplasty between 2013 and 2019 were reviewed. A total of 11 patients were identified, including 8 with classic bladder exstrophy and 3 with cloacal exstrophy. In each case, flap dimensions, donor and recipient vessels and nerves, complications, outcomes and subsequent surgical procedures are reported. RESULTS: A radial forearm free flap was performed in 6 patients and a pedicled anterolateral thigh flap in 5. Flap survival was observed in all cases and 5 patients subsequently received an inflatable penile prosthesis. Among patients undergoing a pedicled anterolateral thigh flap, there was 1 mortality from acute pulmonary embolism, and the other 4 required at least 1 debulking procedure. CONCLUSIONS: Phalloplasty is an important procedure in patients with exstrophy-epispadias complex with severe penile inadequacy. Both techniques have favorable long-term outcomes, although the pedicled anterolateral thigh flap frequently requires a later debulking procedure. The radial forearm free flap is preferred but if the radial forearm is overly thin and the risk of inflatable penile prosthesis extrusion is high, the pedicled anterolateral thigh flap is an acceptable alternative.

Human Spheroids from Adipose-Derived Stem Cells Induce Calvarial Bone Production in a Xenogeneic Rabbit Model.

ABSTRACT: Calvarial defects can result from several causes. Tissue engineering hold the potential to restore native form and protective function. We have recently shown that stemness and differentiation ability of spheroids from adipose-derived stem cells (S-ASCs) promotes osteoblasts growth within Integra in a small vertebral lesion. In our study, we aimed to test osteogenic potential of S-ASCs in aiding regeneration of a calvarial defect. Groups containing Integra showed increased bone regeneration at the calvarial defect-Integra interface compared with the control group. In particular, S-ASC-derived osteoblasts group showed a superior calvarial remodeling than undifferentiated S-ASCs group. Clusters of ossification were observed in these both groups with enhanced microvasculature density and fibrosis. In conclusion, seeding of S-ASCs in dermal regeneration templates enhanced bone healing in a rabbit calvarial defect model. These findings could prompt the elective use of S-ASCs with enhanced multilineage differentiation potential for tissue engineering purposes.

Design of a Novel Reproducible Cartilage-Sparing Autologous Technique for Microtia Repair.

Microtia reconstruction through manual carving of autologous rib cartilage has a steep learning curve, is operator dependent, is time consuming, requires multiple stages, and frequently results in suboptimal results with poor patient satisfaction. The use of temporoparietal fascia over polypropylene implants achieves excellent cosmetic outcomes in a single stage, although is burdened by infection and extrusion in some cases. We describe the development of a hybrid technique with a novel device that allows for standardization of the cartilaginous construct, minimization of the need for donor cartilage and operative time, and minimization of the number of stages. Clinical Trial: NCT03624608.

Clinical Impact of Cryopreservation on Split Thickness Skin Grafts in the Porcine Model.

Vital, genetically engineered, porcine xenografts represent a promising alternative to human cadaveric allografts (HCA) in the treatment of severe burns. However, their clinical value would be significantly enhanced if preservation and long-term storage-without the loss of cellular viability-were feasible. The objective of this study was to examine the direct impact of cryopreservation and the length of storage on critical in vivo and in vitro parameters, necessary for a successful, potentially equivalent substitute to HCA. In this study, vital, porcine skin grafts, continuously cryopreserved for more than 7 years were compared side-by-side to otherwise identically prepared skin grafts stored for only 15 minutes. Two major histocompatibility complex (MHC)-controlled donor-recipient pairs received surgically created deep-partial wounds and subsequent grafting with split-thickness porcine skin grafts, differentiated only by the duration of storage. Clinical and histological outcomes, as well as quantification of cellular viability via a series of 3-4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide (MTT) assays, were assessed. No statistically significant differences were observed between skin grafts cryopreserved for 15 minutes vs 7 years. Parametric distinctions between xenografts stored for short- vs long-term durations could not be ascertained across independent clinical, histological, or in vitro evaluative methods. The results of this study validate the ability to reliably preserve, store, and retain the essential metabolic activity of porcine tissues after cryopreservation. Plentiful, safe, and readily accessible inventories of vital xenografts represent an advantageous solution to numerous limitations associated with HCA, in the treatment of severe burns.

Atypical Mycobacterial Infections After Plastic Surgery Procedures Abroad: A Multidisciplinary Algorithm for Diagnosis and Treatment.

BACKGROUND: The recent rise in medical tourism, especially for cosmetic procedures, has been mirrored by an increase in the incidence of infections with Mycobacterium abscessus, which is an atypical mycobacterium that is ubiquitous in aquatic environments. M. abscessus soft tissue infections arise from the use of improperly sterilized water and surgical equipment during surgical procedures, and these infections have devastating consequences if not promptly treated. M. abscessus infections are notoriously difficult to diagnose and properly treat, and therefore, we illustrate a typical case presentation and provide a comprehensive diagnostic and treatment algorithm. METHODS: Of the patients who have presented to our hospital for treatment of cutaneous M. abscessus infections, a representative patient's story was included to illustrate the typical presentation and treatment timeline. The current literature on M. abscessus infections was reviewed, and this literature and the clinical experience of our plastic surgery and infectious disease teams were used in the creation of a diagnostic and treatment algorithm for M. abscessus infections. RESULTS: M. abscessus infections can have an incubation period of months, and the classic presenting signs include purulent drainage, violaceous nodules, and subcutaneous abscesses at the site of a recent surgery. A key finding is persistence of the infection despite debridement and empiric antibiotic treatment. Cultures grown on mycobacterial-specific growth media are considered the diagnostic criterion standard, but high clinical suspicion is enough to warrant the initiation of treatment. Treatment itself consists of surgical drainage and debridement in combination with multidrug antibiotic regimens that typically include amikacin, a macrolide, and a carbapenem or cephalosporin antibiotic, with the option for macrolide and fluoroquinolone maintenance therapy. CONCLUSIONS: M. abscessus cutaneous infections present with unique history and physical examination findings and often require complex diagnostic workups and treatment plans. Increased provider awareness of the management and potential complications of M. abscessus is crucial to the improvement patient outcomes, as is a multidisciplinary approach that incorporates primary care providers, pathologists, plastic surgeons, and infectious disease specialists.

Poly(ε-Caprolactone) Nanofiber Wrap Improves Nerve Regeneration and Functional Outcomes after Delayed Nerve Repair.

BACKGROUND: The purpose of this study was to assess the efficacy of biodegradable, electrospun poly(ε-caprolactone) nanofiber nerve conduits in improving nerve regeneration. METHODS: The authors used a rat forelimb chronic denervation model to assess the effects of poly(ε-caprolactone) conduits on improving nerve regeneration and upper extremity function. Three groups of rats were examined: (1) negative-control animals (n = 5), which underwent 8 weeks of median nerve chronic denervation injury followed by repair with no conduit; (2) experimental animals (n = 5), which underwent 8 weeks of median nerve chronic denervation followed by repair and poly(ε-caprolactone) nerve conduit wrapping of the nerve coaptation site; and (3) positive-control animals (n = 5), which were naive controls. All animals underwent compound muscle action potential and functional testing. At 14 weeks after repair, the median nerve and flexor muscles were harvested for histologic analysis. RESULTS: Histomorphometric analysis of regenerating median nerves demonstrated augmented axonal regeneration in experimental versus negative control animals (total axon count, 1769 ± 672 versus 1072 ± 123.80; p = 0.0468). With regard to functional recovery, experimental and negative-control animals (1.67 ± 0.04 versus 0.97 ± 0.39; p = 0.036) had regained 34.9 percent and 25.4 percent, respectively, of baseline hand grip strength at 14 weeks after repair. Lastly, less collagen deposition at the nerve coaptation site of experimental animals was found when compared to control animals (p < 0.05). CONCLUSION: Biodegradable, poly(ε-caprolactone) nanofiber nerve conduits can improve nerve regeneration and subsequent physiologic extremity function in the setting of delayed nerve repair by decreasing the scar burden at nerve coaptation sites.

Immunomodulation in Vascularized Composite Allotransplantation: What Is the Role for Adipose-Derived Stem Cells?

Hand and face transplants are becoming increasingly common, recording progressively more penile, uterus, abdominal wall, and allotransplantation cases reported worldwide. Despite current protocols allow long-term survival of the allografts, the ultimate goal of donor-specific tolerance has not been achieved yet. In fact, the harmful adverse effects related to the lifelong administration of immunosuppressive agents are the main drawbacks for vascularized composite allotransplantations. Research is very active in investigating alternative methods to induce greater tolerance while minimizing toxicity. Adipose-derived stem cells (ASCs) represent promising cell therapies for immunomodulation in preclinical and clinical settings. Their clinical appeal is due to their easy harvest in large quantities through a noninvasive and well-accepted approach; they may well promote donor-specific tolerance and potentially reduce immunosuppression. Several experimental studies exist, but lacking review articles reporting current evidence. This work proposes a literature review on the immunomodulatory role of ASCs in vascularized composite allotransplantations. In vitro and in vivo evidence will be summarized. The role that cell passaging and upstream progenitors-the so-called spheroid ASCs-may play in modulating the immune response will also be discussed. Finally, this article will summarize current knowledge on biodistribution, migration, and homing of injected stem cells. This review may well provide useful information for preclinical and clinical studies, aiming at a breakthrough for donor-specific tolerance.

International Medical Graduates in the US Plastic Surgery Residency: Characteristics of Successful Applicants.

Objectives: Within the United States, plastic surgery is a difficult field to match into for both US and international medical graduates. While the number of available residency positions has grown in recent years, this has not been mirrored by an equal increase in the number of international medical graduates who match. Furthermore, there are few reliable resources to guide international medical graduates who are interested in matching into US-based programs, so the process is often even more difficult and unpredictable than for US applicants. Methods: An anonymous survey was distributed electronically to international medical graduates who successfully matched into independent and integrated US plastic surgery residency programs. The survey assessed qualities such as medical school performance, test scores, research experience, and other relevant applicant information, and χ2 analysis was done to compare the survey results for integrated and independent track international medical graduates. Results: International medical graduates who successfully match tend to rank high and score well in their medical school classes, score between 230 and 250 on USMLE step 1 and 2CK tests, and have a mean of 2 years of research experience before applying to the match. International medical graduates in the independent track tend to have higher step 1 scores, whereas international medical graduates in the integrated track tend to have more research experience and additional nonmedical degrees. Conclusions: This is a survey-based overview that describes the characteristics of successfully matched international medical graduates. Limitations of this study include the inability to identify and survey the unsuccessful applicants as well as poor response rate of the successful candidates in the independent pathway who successfully matched.
