A Nationwide Analysis of the Impact of Cardiopulmonary Anomalies on Cleft Palate Surgical Outcomes.

OBJECTIVE: To increase awareness and improve perioperative care of patients with cleft palate (CP) and coexisting cardiopulmonary anomalies. DESIGN: Retrospective cohort. SETTING: Multi-center. PATIENTS/PARTICIPANTS: Patients who underwent surgical repair of CP between 2012-2020 identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric Data File. Chi-squared analysis and Student's t-test were implemented to make associations between congenital heart disease (CHD) and congenital pulmonary disease (CPD) and postoperative complications. Multiple logistic regression was performed to identify associations between CP and CHD/CPD while controlling for age, gender, and ASA class. C2 values were used to assess the logistic regressions, with a significance level of 0.05 indicating statistical significance. MAIN OUTCOMES MEASURES: Length of stay (LOS), perioperative complications (readmission, reoperation, reintubation, wound dehiscence, cerebrovascular accidents, and mortality). RESULTS: 9 96 181 patients were identified in the database, 17 786 of whom were determined to have CP, of whom 16.0% had congenital heart defects (CHD) and 13.2% had congenital pulmonary defects (CPD). Patients with CHD and CPD were at a significantly greater risk of increased LOS and all but one operative complication rate (wound dehiscence) relative to patients with CP without a history of CHD and CPD. CONCLUSION: This study suggests that congenital cardiopulmonary disease is associated with increased adverse outcomes in the setting of CP repair. Thus, heightened clinical suspicion for coexisting congenital anomalies in the presence of CP should prompt referring providers to perform a comprehensive and multidisciplinary evaluation to ensure cardiopulmonary optimization prior to surgical intervention.

A National Analysis of Craniosynostosis Demographic and Surgical Trends Over a 10-Year Period.

The pathogenesis of craniosynostosis, characterized by the premature fusion of calvarial sutures, is multifaceted and often the result of an amalgamation of contributing factors. The current study seeks examine the possible contributors to craniosynostosis development and its surgical trends over time. A multicenter/national retrospective cohort study was conducted of patients who underwent surgical repair of craniosynostosis (n=11,279) between 2012 and 2021 identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric Data File. Main outcome measures included risk factors and trends relating to surgical repair of craniosynostosis. Nationwide reports of craniosynostosis in the NSQIP-P database have increased between 2012 and 2021 by 195%. The prevalence of craniosynostosis per overall cases has remained between 1.0% and 1.3%. There were predominantly more White male patients in the craniosynostosis cohort (P<0.001). Craniosynostosis patients had significantly greater birth weights, gestational ages, and were less likely to be premature (P<0.05). Linear regression demonstrated that operative time, anesthesia time, and length of stay significantly decreased over the study period (P<0.001). This national data analysis highlights trends in craniosynostosis repair indicating potential improvements in safety and patient outcomes over time. While these findings offer insights for health care professionals, caution is warranted in extrapolating beyond the data's scope. Future research should focus on diverse patient populations, compare outcomes across institutions, and employ prospective study designs to enhance the evidence base for craniosynostosis management. These efforts will help refine diagnostic and treatment strategies, potentially leading to better outcomes for patients.

A Systematic Review of Simulation in Burn Care: Education, Assessment, and Management.

Assessment and management of burns require nuanced, timely interventions in high-stake settings, creating challenges for trainees. Simulation-based education has become increasingly popular in surgical and nonsurgical subspecialties to supplement training without compromising patient safety. This study aimed to systematically review the literature on existing burn management-related simulations. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles describing burn-specific surgical and nonsurgical simulation models were included. The model type, study description, simulated skills, assessment methods, fidelity, cost, and outcomes were collected. Of 3,472 articles, 31 met inclusion criteria. The majority of simulations were high-fidelity (n=17, 54.8%). Most were immersive (n=17, 54.8%) and used synthetic benchtop models (n=13, 41.9%), whereas none were augmented/virtual reality. Simulations of acute and early surgical intervention techniques (n=16, 51.6%) and burn wound assessments (n=15, 48.4%) were the most common, whereas burn reconstruction was the least common (n=3, 9.7%). Technical skills were taught more often (n=29, 93.5%) than non-technical skills (n=15, 48.4%). Subjective assessments (n=18, 58.1%) were used more often than objective assessments (n=23, 74.2%). Of the studies that reported costs, 91.7% (n=11) reported low costs. This review identified the need to expand burn simulator options, especially for burn reconstruction, and highlighted the paucity of animal, cadavers, and augmented/virtual reality models. Developing validated, accessible burn simulations to supplement training may improve education, patient safety, and outcomes.

A systematic review of surgical simulation in gender affirmation surgery.

The burgeoning field of gender affirmation surgery (GAS) has become increasingly complex, challenging plastic surgeons to meet high standards for their patients. During the COVID-19 pandemic, the emphasis on remote learning ushered in the increased use of surgical simulation training, offering residents the opportunity to trial challenging procedures before treating patients. This systematic review seeks to summarize current simulation training models used in GAS. A systematic review was conducted according to PRISMA-P guidelines using the following databases: PubMed, Medline, Scopus, Embase, Web of Science, and Cochrane. Inclusion criteria were English-language peer-reviewed articles on surgical simulation techniques or training related to the field of gender surgery. Skills and techniques taught and assessed, model type, equipment, and cost were abstracted from articles. Our search criteria identified 1650 articles, 10 of which met the inclusion criteria for data extraction. Simulation models included those that involved cadavers (n = 2), synthetic benchtop (n = 5), augmented/virtual reality (n = 2), and 3D-printed interfaces (n = 1). The most common procedure involved breast or pectoral reconstruction and/or augmentation (n = 5), followed by vaginal reconstruction (n = 3). One simulation model involved facial GAS. All models focused on surgical technique and anatomy, three on suture skills or knot-tying, and one on surgical decision-making. The evolving field of GAS requires that plastic surgery trainees be knowledgeable on surgical techniques surrounding this scope of practice. Surgical simulation not only teaches residents how to master techniques but also helps address the sensitive nature of GAS.

A Calvarial Defect Model to Investigate the Osteogenic Potential of Umbilical Cord Stem Cells in Bone Regeneration.

BACKGROUND: The standard graft material for alveolar cleft repair (ACR) is autogenous iliac crest. A promising alternative potential graft adjunct-newborn human umbilical cord mesenchymal stem cells (h-UCMSCs)-has yet to be explored in vivo. Their capacity for self-renewal, multipotent differentiation, and proliferation allows h-UCMSCs to be harnessed for regenerative medicine. This study sought to evaluate the efficacy of using tissue-derived h-UCMSCs and their osteogenic capabilities to improve ACR in a murine model. METHODS: Foxn1 mice were separated into three groups with the following calvarial defects: no treatment (empty defect; n = 6), poly(D,L-lactide-co-glycolide) (PLGA) scaffold ( n = 6), or h-UCMSCs with PLGA ( n = 4). Bilateral 2-mm-diameter parietal bone critical-sized defects were created using a dental drill. Microcomputed tomography (microCT) imaging was performed 1, 2, 3, and 4 weeks postoperatively. The mice were euthanized 4 weeks postoperatively for RNAScope, immunohistochemical, and histological analysis. RESULTS: No mice experienced complications during the follow-up period. MicroCT imaging and histological analysis demonstrated that the no-treatment and PLGA-only defects remained patent without significant defect size differences across groups. In contrast, the h-UCMSCs with PLGA group had significantly greater bone fill on microCT and histological analysis. CONCLUSIONS: This study demonstrates a successful calvarial defect model for the investigation of h-UCMSC-mediated osteogenesis and bone repair. Evidence reveals that PLGA alone has neither short-term effects on bone formation nor any unwanted side effects, making it an attractive scaffold. Further investigation using h-UCMSCs with PLGA in larger animals is warranted to advance future translation to patients requiring ACR. CLINICAL RELEVANCE STATEMENT: The authors' results demonstrate a successful murine calvarial defect model for the investigation of h-UCMSC-mediated osteogenesis and bone repair, and they provide preliminary evidence for the safe and efficacious use of this graft adjunct in alveolar cleft repair.

Extreme Limb Salvage: The Thin SCIP Flap for Distal Amputation Coverage in Highly Comorbid Patients.

INTRODUCTION: Limb length preservation is correlated with overall survival. Successful free flap coverage of fore-, mid- and hind-foot amputations can prevent more proximal below-knee amputations but is challenging in patients with multiple comorbidities. The thin superficial circumflex iliac artery perforator (SCIP) flap is well-suited for these patients as it provides thin, pliable tissue from a favorable donor site. METHODS: A retrospective review of all patients with distal amputations requiring coverage with a thin SCIP flap between 2016 to 2022 was performed. Patient demographics, amputation levels, and wound characteristics as well as flap and microsurgery details were analyzed. The primary outcome was limb salvage. Secondary outcomes included partial flap necrosis, flap revision rate and additional postoperative complications. RESULTS: Thirty-two patients (mean age 57.3) underwent reconstruction of fore-, mid- and hindfoot amputations with thin SCIP flaps (mean follow-up 36 months). Twenty-eight patients (87.5%) had diabetes, 27 (84.4%) had peripheral artery disease and 15 (46.9%) were dialysis-dependent. Average flap size was 59.5cm2 and average flap thickness was 5.7mm. Successful limb salvage was achieved in 27 patients (84.3%). Three cases (9.4%) had total flap loss. Twenty-one flaps (65.6%) had partial necrosis of which 12 (57.1%) healed with conservative management and seven (33.3 %) healed after late revision. CONCLUSION: The thin SCIP flap is a useful option for coverage of distal pedal amputations in patients with significant comorbidities. Despite higher rates of partial flap necrosis, free flap reconstruction allowed for high rates of limb salvage in a challenging patient population.

Outcomes of Local Versus Free Flaps for Reconstruction of the Proximal One-Third of the Leg.

BACKGROUND: Reconstruction of the proximal one-third of the leg often requires soft tissue transfer to facilitate limb salvage. Tissue transfers are usually local or free flaps depending on wound dimensions, location, and surgeon preference. Historically, the proximal third of the leg was covered with pedicle flaps, but recently, we have used more free flaps in this position. Using data from a level 1 trauma center, we sought to evaluate outcomes of surgical management of proximal-third leg reconstruction across local and free flaps. METHODS: This is an institutional review board-approved, retrospective chart review undertaken at LAC + USC Medical Center from 2007 to 2021. Patient history, demographics, flap characteristics, Gustilo-Anderson fracture classification, and outcomes were collected and analyzed in an internal database. Outcomes of interest included flap failure rates, postoperative complications, and long-term ambulatory status. RESULTS: Among 394 lower extremity flaps placed, 122 flaps involved the proximal-third leg across 102 patients. Average age of patients was 42.8 ± 15.2 years; of note, the free flap cohort was significantly younger than the local flap cohort (P = 0.019). Ten local flaps suffered from infectious complications: osteomyelitis (n = 6) and hardware infection (n = 4), versus only 1 free flap that suffered from hardware infection; notably, these differences were not significant across cohorts. Free flaps had significantly more flap revisions (13.3%; P = 0.039) and overall flap complications (20.0%; P = 0.031) compared with local flaps; however, partial flap necrosis (4.9%) and flap loss (3.3%) were not significantly different across cohorts. Overall flap survival was 96.7%, and full ambulation was achieved in 42.2% of patients without significant differences across cohorts. CONCLUSIONS: Our evaluation of proximal-third leg wounds demonstrates fewer infectious outcomes with free flaps compared with local flaps. There are multiple confounding variables; however, this finding may speak to the reliability of a robust free flap. Overall, there was no significant difference in patient comorbidities across flap cohorts with great overall flap survival. Ultimately, flap selection did not affect rates of flap necrosis, flap loss, or final ambulatory status.

Does Early Referral Lead to Early Repair? Quality Improvement in Cleft Care.

BACKGROUND: Cleft lip and palate is the most common congenital defect of the head and neck, occurring in 1 of 700 live births. Diagnosis often occurs in utero by conventional or 3-dimensional ultrasound. Early cleft lip repair (ECLR) (<3 months of life) for unilateral cleft lip (UCL), regardless of cleft width, has been the mainstay of lip reconstruction at Children's Hospital Los Angeles since 2015. Historically, traditional lip repair (TLR) was performed at 3 to 6 months of life ± preoperative nasoalveolar molding (NAM). Previous publications highlight the benefits of ECLR, such as enhanced aesthetic outcomes, decreased revision rate, better weight gain, increased alveolar cleft approximation, cost savings of NAM, and improved parent satisfaction. Occasionally, parents are referred for prenatal consultations to discuss ECLR. This study evaluates timing of cleft diagnosis, preoperative surgical consultation, and referral patterns to validate whether prenatal diagnosis and prenatal consultation lead to ECLR. METHODS: Retrospective review evaluated patients who underwent ECLR versus TLR ± NAM from 2009 to 2020. Timing of repair, cleft diagnosis, and surgical consultation, as well as referral patterns, were abstracted. Inclusion criteria dictated: age < 3 months for ECLR or 3 to 6 months for TLR, no major comorbidities, and diagnosis of UCL without palatal involvement. Patients with bilateral cleft lip or craniofacial syndromes were excluded. RESULTS: Of 107 patients, 51 (47.7%) underwent ECLR whereas 56 underwent TLR (52.3%). Average age at surgery was 31.8 days of life for the ECLR cohort and 112 days of life for the TLR cohort. Furthermore, 70.1% of patients were diagnosed prenatally, yet only 5.6% of families had prenatal consults for lip repair, 100% of which underwent ECLR. Most patients were referred by pediatricians (72.9%). Significance was identified between incidence of prenatal consults and ECLR (P = 0.008). In addition, prenatal diagnosis was significantly correlated with incidence of ECLR (P = 0.027). CONCLUSIONS: Our data demonstrate significance between prenatal diagnosis of UCL and prenatal surgical consultation with incidence of ECLR. Accordingly, we advocate for education to referring providers about ECLR and the potential for prenatal surgical consultation in the hopes that families may enjoy the myriad benefits of ECLR.

Comparative Evaluation of the Electronic Residency Application Service Versus the Plastic Surgery Common Application to a Single Institution in the 2022 Integrated Plastic Surgery Match.

BACKGROUND: The Plastic Surgery Common Application (PSCA) has emerged as a low-cost alternative application portal to the Electronic Residency Application Service (ERAS) for integrated plastic surgery applicants. During the 2021 to 2022 application cycle, our plastic surgery residency program accepted both the PSCA and ERAS applications to help recruit candidates otherwise deterred by prohibitively high application costs. We sought to determine how the PSCA compared with the ERAS application in a standardized review of applications scores. METHODS: The PSCA and ERAS applications from 28 candidates who received interviews from the Keck School of Medicine were analyzed. These 56 applications were randomly assigned across 22 independent reviewers. Each reviewer scored applications on a scale of 1 to 5 with regard to communication skills, leadership, intellectual curiosity, compatibility with the program, service, and perseverance. Mean scores between the applications were compared using 2-tailed z tests, with statistical significance set at P < 0.05. RESULTS: The 56 residency applications had a combined mean score of 4.21 (95% confidence interval [CI], 4.13-4.29). The mean score of PSCA applications (4.19; 95% CI, 4.08-4.31) did not significantly differ from the mean score of ERAS applications (4.24; 95% CI, 4.12-4.35; P = 0.57). The PSCA and ERAS applications did not have a significant difference in the mean scores for any review category. CONCLUSION: There was no difference between the overall scores and the scores of each review category between the PSCA and ERAS applications, suggesting that the PSCA may be a reasonable alternative to ERAS for medical students applying to plastic surgery residency.

The Free Superficially Based Low-Abdominal Mini Flap for Oncoplastic Breast Reconstruction.

SUMMARY: Volume replacement in oncoplastic breast reconstruction most commonly uses pedicled flaps. In thin patients with small breasts, free-tissue transfer may be better suited to preserve breast size. Evidence on microvascular oncoplastic reconstruction is limited, and reconstruction has often required sacrifice of potential future donor sites. The free superficially based low-abdominal mini (SLAM) flap uses a narrow strip of lower abdominal tissue based on superficial perfusion of the abdominal wall that is anastomosed to chest wall perforators to preserve the ability to perform future abdominally based autologous breast reconstruction. Five patients underwent reconstruction with SLAM flaps for immediate oncoplastic reconstruction. Their mean age was 49.8 years, and their mean body mass index was 23.5. Tumor location was most commonly in the lower outer quadrant (40%). Average lumpectomy weight was 30 g. Two flaps were based on the superficial inferior epigastric artery, and three, on the superficial circumflex iliac artery. Recipient vessels included internal mammary perforators (40%), serratus branch (20%), lateral thoracic vessel branch (20%), and lateral intercostal perforators (20%). All patients underwent radiation therapy without delay and maintained volume, symmetry, and contour at an average period of 11.7 months after surgery. There were no cases of flap loss, fat necrosis, or delayed wound healing. The free SLAM flap allows for immediate oncoplastic breast reconstruction in thin, small-breasted patients with limited regional tissue without sacrificing future potential donor sites for autologous breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Tympanostomy Tubes: Are They Necessary? A Systematic Review on Implementation in Cleft Care.

OBJECTIVE: To understand the indication for and the effects of early ventilation tube insertion (VTI) on hearing and speech for patients with cleft lip and/or palate (CLP). DESIGN: We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-guided systematic review of relevant literature. SETTING: Setting varied by geographical location and level of clinical care across studies. PATIENTS, PARTICIPANTS: Patients with CLP who underwent VTI were included. INTERVENTIONS: No interventions were performed. MAIN OUTCOME MEASURE(S): Primary outcome measures were hearing and speech following VTI. Secondary outcome measures were tube-related and middle ear complications. Early VTI occurred before or at time of palatoplasty while late VTI occurred after palatoplasty. RESULTS: Twenty-three articles met inclusion criteria. Articles varied among study design, outcome measures, sample size, follow-up, and quality. Few studies demonstrated support for early VTI. Many studies reported no difference in hearing or speech between early and late VTI. Others reported worse outcomes, greater likelihood of complications, or needing repeat VTI following early tympanostomy placement. Several studies had significant limitations, including confounding variables, small sample size, or not reporting on our primary outcome. CONCLUSIONS: No consistency was found regarding which patients would benefit most from early VTI. Given the aforementioned variability and sub-optimal methodologies, additional studies are warranted to provide stronger evidence regarding VTI timing in cleft care.

Rethinking the Rule of 10s: Early Cleft Lip Repair Improves Weight Gain.

OBJECTIVE: This study compares patients undergoing early cleft lip repair (ECLR) (<3-months) and traditional lip repair (TLR) (3-6 months) with/without nasoalveolar molding (NAM) to evaluate the effects of surgical timing on weight gain in hopes of guiding future treatment paradigms. DESIGN: Retrospective review. SETTING: Children's Hospital of Los Angeles, California. PATIENT, PARTICIPANTS: A retrospective chart review evaluated patients who underwent ECLR or TLR ± NAM from November 2009 through January 2020. INTERVENTIONS: No intervention was performed. MAIN OUTCOME MEASURE(S): Patient demographics, birth and medical history, perioperative variables, and complications were collected. Infant weights and age-based percentiles were recorded at birth, surgery, 8-weeks, 6-months, 12-months, and 24-months postoperatively. The main outcomes were weight change and weight percentile amongst ECLR and TLR ± NAM groups. RESULTS: 107 patients met inclusion criteria: ECLR, n = 51 (47.6%); TLR + NAM, n = 35 (32.7%); and TLR-NAM, n = 21 (19.6%). ECLR patients had significantly greater changes in weight from surgery to 8-weeks and from surgery to 24-months postoperatively compared with both TLR ± NAM (P < .05). Age-matched weights in the ECLR group were significantly greater than TLR ± NAM at multiple time points postoperatively (P < .05). CONCLUSIONS: ECLR significantly increased patient weights 24-months postoperatively when compared to TLR ± NAM. Specifically compared to TLR-NAM, ECLR weights were significantly greater at all time points past 6-months postoperatively. The results of this study demonstrate that ECLR can mitigate feeding difficulties and malnutrition traditionally seen in patients with cleft lip.

Fungating Malignancies: Management of a Distinct Wound Entity.

GENERAL PURPOSE: To provide information on the surgical management of fungating malignancies as a distinct wound entity. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Identify characteristics of patients in a study examining the treatment of fungating malignancies.2. Select common symptoms experienced by patients with fungating malignancies.3. Explain issues related to the surgical treatment of fungating malignancies.4. Identify a reason why patients with fungating breast masses may avoid medical care.

To address the literature gap on malignant fungating wound treatment by reporting two institutions' experiences with this disease process and proposing practices to improve care. A multi-institutional retrospective review was conducted of 44 patients with 45 malignant fungating wounds over an 11-year period. Patient characteristics, treatment history, and outcomes were analyzed. Of the 44 patients who met the inclusion criteria, 31 (70.5%) were women and 13 (29.5%) were men. The average age at presentation was 63.0 (SD, 16.1) years. The most common malignancy was breast cancer, accounting for more than half of cases (54.5%). The average surface area of the tumors at presentation was 110.3 (SD, 215.0; range, 2.2­1,140) cm 2 , whereas the average surface area at time of discharge/death was 104.6 (SD, 310.7; range, 0­1,800) cm 2 . Neither surface area at presentation ( P = .504) nor surface area at time of final follow-up ( P = .472) were significantly associated with death during the study time frame. In the era of advancing technologies and medical innovation, the benefits of palliative surgery, which helps mitigate an open wound, should not be overlooked. Improving end-of-life care is beneficial to the patient and families alike. As surgeons, we strive for a tangible cure, but providing palliative resection to enable death with dignity might be the most humane service of all.

Premaxillary Setback in Bilateral Cleft Lip and Palate Repair.

OBJECTIVE: The aim of this study is to evaluate surgical outcomes and maxillofacial growth in patients undergoing primary lip repair with or without premaxillary setback. DESIGN: Retrospective review. SETTING: Children's Hospital of Los Angeles, California. PATIENTS AND PARTICIPANTS: Patients with bilateral cleft lip ± palate (BCLP) who underwent lip repair with or without premaxillary setback from January 1975 to September 2021. INTERVENTIONS: No intervention was performed. MAIN OUTCOME MEASURE(S): Patient demographics, comorbidities, and syndromic status were obtained. Indications for premaxillary setback, incidence of midface hypoplasia, orthodontic and/or orthognathic treatments, follow-up, complications, and revisions were recorded and analyzed. Comparisons among long-term outcomes, particularly the development of midface hypoplasia were made between groups. RESULTS: Thirty-one patients who underwent BCLP repair with premaxillary setback (BCLP + PS) and 31 matched control patients who underwent BCLP repair without premaxillary setback (BCLP - PS) were included. Among the 2 groups, multiple logistic regression demonstrated that when controlling for comorbidities, syndromic status, timing of lip repair, and timing of palate repair, premaxillary setback was neither significantly associated with the development of midface hypoplasia (P = .076) nor the timing of midface hypoplasia development (P = .940) in those that ultimately acquired this facial dysmorphology. CONCLUSIONS: While a high incidence of midface hypoplasia was seen in both BCLP ± PS and BCLP - PS, our findings demonstrate no difference in midface hypoplasia irrespective of premaxillary setback in the setting of BCLP. Future prospective studies investigating the downstream ramifications of our suggested selection criteria for premaxillary setback are warranted.

Meeting in the middle: pediatric abdominal wall reconstruction for omphalocele.

BACKGROUND: Omphalocele is a congenital abdominal wall defect with an incidence of 1/4,200 births. Repair timing varies from the neonatal period to the first few years of life. Surgical technique has changed over the last two decades. We sought to establish improved surgical/ventilation protocols for patients with omphaloceles requiring abdominal reconstruction. METHODS: An IRB-approved retrospective review was performed on patients with omphalocele requiring abdominal wall reconstruction by Plastics and/or Pediatric Surgery at a pediatric tertiary-care referral center (January 2006-July 2021). Birth history, comorbidities, surgical details, ventilation data, complications/recurrence were extracted. RESULTS: Of 129 patients screened, seven required Plastic Surgery involvement. Defect size was 102.9 cm2 (range: 24-178.5); five patients required component separation; zero patients received mesh; zero complications/recurrences were recorded. Two patients required postoperative ventilation for 2.5 days, based on increased peak inspiratory pressures at surgery stop versus start time. CONCLUSION: Patients with large defects secondary to omphalocele benefit from collaboration between Pediatric and Plastic Surgery for component separation and primary fascial closure without mesh. Future research should follow patients who mature out of pediatric clinics to evaluate the incidence of hernias in adults with Plastic Surgery-repaired omphaloceles.

A Unique Case of Aggressive Central Giant Cell Granuloma in a 10-Year-Old Boy With 16p13.11 Microdeletion Syndrome.

Central giant cell granuloma (CGCG) is a rare disease characterized by sporadic, benign, intraosseous mandibular lesions of unknown etiology. Histologically, these lesions are indistinguishable from brown tumors of hyperparathyroidism and cherubism, and occasionally have been associated with different syndromes raising a question for genetic etiology. The CGCG has varied presentation ranging from nonaggressive and indolent to aggressive, destructive, and recurrent, often posing diagnostic and therapeutic challenges. Herein, we present the first case of a 10-year-old boy with CGCG and 16p13.11 microdeletion syndrome, highlight the diagnostic challenges inherent to this heterogeneous disorder, and discuss the genetics and treatment approaches of these complex lesions.

Syndromic Synostosis: Frontofacial Surgery.

Frontofacial surgery, encompassing the monobloc with or without facial bipartition and the box osteotomy, can treat the frontal bone and midface simultaneously, providing comprehensive improvement in facial balance. Complex pediatric patients with genetic syndromes and craniosynostosis are most optimized by an interdisciplinary team of surgeons, pediatricians, geneticists, speech pathologists, audiologists, dietitians, pediatric dentists, orthodontists, and psychosocial support staff to manage the myriad of challenges and complications throughout early childhood and beyond. Despite early treatment of the anterior and posterior cranial vault, these patients frequently have resultant frontal and/or midface hypoplasia and orbital abnormalities that are best managed with simultaneous surgical treatment.

Increased Distraction Magnitude Leads to Greater Reduction in the Apnea-Hypopnea Index in Infants With Robin Sequence.

PURPOSE: Upper airway obstruction seen in Robin Sequence (RS) is commonly treated with mandibular distraction osteogenesis (MDO). The purpose of this study is to evaluate the impact of distraction distance on sleep study outcomes in patients with obstructive sleep apnea (OSA) secondary to RS. METHODS: A retrospective cohort study was conducted for patients with isolated RS who underwent MDO at Children's Hospital Los Angeles between January 2006-September 2021. The predictor variable was distraction distance (maximal distraction using a 30 mm device vs sub-maximal distraction), and the primary outcome variable was OSA scores. Relationships between covariates, including demographic characteristics, preoperative sleep variables, and postoperative OSA outcomes using polysomnography, were also analyzed. Descriptive statistics and tests of statistical significance were performed using the Statistical Package for Social Sciences (SPSS) (version 28.0), including Student's t-test, proportions testing, multiple linear regression, and correlation analysis. RESULTS: Seventy-one patients met inclusion criteria (39.4% female, 60.6% male). Average age at MDO was 3.0 ± 10.2 months. Fifty-six patients were distracted maximally with a 30 mm distractor, while the remaining 15 patients experienced shorter distraction due to distractor limitations (25 mm distractor), persistent infection or family request. Looking at absolute values of postoperative sleep study variables, there were no significant differences between patients who were maximally and sub-maximally distracted across apnea-hypopnea index (AHI), highest carbon dioxide, lowest oxygen saturation, and oxygen requirement. However, both cohorts demonstrated significant improvements in lowest oxygen saturation, AHI, highest carbon dioxide level, and highest oxygen requirement compared to their pre-distraction levels. Compared with patients distracted <30 mm, maximal distraction had a significantly greater improvement in AHI when controlling for preoperative sleep study variables (P = .047). CONCLUSION: Patients with isolated RS who have more severe OSA experienced greater improvements in AHI, oxygen requirement, and oxygen saturation after MDO. Two-thirds of patients no longer had oxygen requirements after MDO. Our results suggest that MDO is helpful in treating patients with RS regardless of distraction distance. However, our study provides evidence that increasing the distraction distance may further improve AHI, which is particularly beneficial to patients with a significant preoperative AHI.

Outcomes of Local versus Free Flaps for Lower Extremity Trauma.

BACKGROUND: Lower extremity reconstruction often requires soft tissue transfer for limb salvage. Flaps are allocated based on injury size, location, and shape coupled with surgeon expertise. Ideally, vascularized tissue should have similar outcomes across local and free tissue transfers. By evaluating outcomes from a Level 1 trauma center, we aim to provide recommendations regarding surgical management of leg reconstruction with respect to local versus free flap implementation. METHODS: This retrospective review evaluated patient medical history, demographics, flap characteristics, and outcomes from LAC + USC between 2007-2021 using an internal database. Outcomes included failure rates, complications, and ambulation. RESULTS: 357 lower extremity flaps were placed on 322 patients; 187 (52.4%) were local and 170 (47.6.%) were free flaps. Twenty-one (11.2%) local flaps suffered significantly more postoperative hardware infections and/or osteomyelitis compared to nine (5.3%) free flaps. Eleven (5.9%) local flaps developed partial necrosis, four requiring revision; 12 (6.4%) total local flaps required revision. Comparatively, sixteen (9.4%) free flaps developed partial necrosis, seven requiring revision; 18 (10.6%) total free flaps required revision. Flap survival was 96.3% for local versus 93.5% for free flaps. Percentage of fully ambulatory patients and time to final ambulation was not significant across cohorts. DISCUSSION: Local flaps may portent higher risk for infection; though the cause is not clear, the results may be confounded by comorbidities. Nevertheless, there were no significant differences in flap survival or number of fully ambulatory patients across cohorts. Future studies should evaluate aesthetic results and patient satisfaction across flap types.

"Systematic review and meta-analysis of immediate versus delayed autologous breast reconstruction in the setting of post-mastectomy adjuvant radiation therapy".

BACKGROUND: Immediate post-mastectomy autologous breast reconstruction in breast cancer patients requiring post-mastectomy radiation therapy (PMRT) minimizes the number of operations that patients must undergo and alleviates the psychological impact of living without a breast. However, the safety and impact of radiation on the reconstructed breast remains to be established. This study aimed to compare immediate versus delayed autologous reconstruction in the setting of PMRT to determine the optimal sequencing of reconstruction and adjuvant radiation. METHODS: A systematic review of the literature identified 292 studies meeting criteria for full-text review, 44 of which underwent meta-analysis. This represented data on 1,927 immediate reconstruction (IR) patients and 1,546 delayed reconstruction (DR) patients (3,473 total patients). Early complications included flap loss, fat necrosis, thrombosis, seroma, hematoma, infection, and skin dehiscence. Late complications included fibrosis or contracture, severe asymmetry, hyperpigmentation, and decreased flap volume. RESULTS: Immediate breast reconstruction did not demonstrate significantly increased complication rates. Reported mean complication rates in IR versus DR groups, respectively, were fat necrosis 14.91% and 8.12% (p = 0.076), flap loss 0.99% and 1.80% (p = 0.295), hematoma 1.91% and 1.14% (p = 0.247), infection 11.66% and 4.68% (p = 0.155), and thrombosis 1.51% and 3.36% (p = 0.150). Seroma rates were significantly lower in the immediate cohort at 2.69% versus 10.57% in the delayed cohort (p = 0.042). CONCLUSION: Complication rates are comparable between immediate and delayed breast reconstruction in the setting of PMRT. Given the patient benefits incurred by an IR algorithm, immediate autologous breast reconstruction should be considered as a viable treatment option in patients requiring PMRT.
