Objective To evaluate the incidence and characteristics of secondary synostosis following spring-mediated cranioplasty (SMC) for nonsyndromic sagittal craniosynostosis. Design Retrospective cohort study. Setting Single tertiary pediatric hospital. Patients/Participants Ten patients with isolated sagittal craniosynostosis who underwent primary SMC between 2021 and 2023. Patients with syndromic diagnoses or prior cranial surgery were excluded. Interventions SMC was performed using 2 to 3 stainless-steel springs following sagittal strip craniectomy. Springs were typically removed 3 to 4 months postoperatively. Follow-up included review of clinical photographs, radiographs, and operative records. Main Outcome Measures Change in cephalic index (CI) from preoperative to postoperative assessment and occurrence of secondary suture fusion, particularly coronal synostosis. Results Mean age at surgery was 4 months (range, 3-6 months). Mean CI improved from 68.5 to 79 following expansion. Three patients (30%) developed left unicoronal synostosis (UCS) during the perioperative period prior to spring removal. One patient required secondary coronal suturectomy for significant frontal asymmetry, while 2 were observed without intervention. Conclusions Secondary synostosis, particularly UCS, may represent an underrecognized sequela of SMC. Altered biomechanical forces or asymmetric cranial remodeling during distraction may contribute to this finding. Larger, multicenter studies with longitudinal imaging are warranted to determine incidence, risk factors, and preventive strategies.

Abstract Robots have been used effectively in plastic and reconstructive surgery (PRS) for reconstruction. The utilization of robotics in all surgical specialties is expanding with the goal of offering the most appropriate patient-centered care possible, especially in complex multidisciplinary cases. Despite the safety, efficiency, and reproducibility of robotics in PRS, there is a paucity of required and formalized training in PRS residency programs. The ACGME and industry published guidelines were investigated. Robotic surgery case logs of Mayo Clinic Arizona General Surgery residents were analyzed with attention to equivalency certification (EQ). Over the past 5 years, the equivalency certification from Intuitive (Sunnyvale, CA) was obtained by 30% of all general surgery residents at our institution (range, 0–100). The case numbers to obtain the equivalence certification are industry recommendations, and proficiency is determined by the program director. The ACGME does not mandate robotics training in general surgery residency. According to the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), trainees must complete 20 console cases and 10 bedside cases to become industry certified. With respect to training and advancing the field, PRS residents could successfully obtain certification in their residency programs. The minimum case requirement recommended by SAGES is not burdensome and can ensure robotic privileges in PRS practice immediately following graduation. By improving the training for minimally invasive robotic surgery in plastic surgery, patients and healthcare systems benefit from improved quality of life outcomes and decreased postoperative length of stay, which results in less strain on our entire medical system.

Lymphedema is a frequent complication of breast cancer treatment. As the survival rates of breast cancer continue to increase, the number of women with lymphedema will also increase. Surgical treatment of lymphedema has made significant advances during the past 20 years, and our understanding of these procedures continues to evolve. Vascularized lymph node transfer is an increasingly popular option for surgical treatment of lymphedema; however, the mechanism behind symptomatic relief is not fully understood. A proposed theory for improvement in lymphedema symptoms is lymphangiogenesis and spontaneous regeneration of lymphatic vessels, the timing and degree of which are not well defined. We present the case of a 40-year-old woman with a 10-year history of right upper extremity lymphedema secondary to bilateral mastectomy and right axillary lymph node dissection, who subsequently underwent vascularized omental lymph node transfer and lymphovenous bypass with radiographic evidence of spontaneous lymphatic reconnection within 9 months. To our knowledge, this is the earliest reported radiographic evidence of lymphatic regeneration in a human subject to date, adding to the growing body of evidence to support the therapeutic benefits of vascularized lymph node transfers.

Abstract Background The presence of a chimeric gracilis and profunda artery perforator (PAP) flap with a common arterial pedicle has been demonstrated on computed tomography angiography in up to 59% of patients and confirmed in a cadaveric model. Already utilized for head and neck reconstruction by Heredero et al, this novel flap could provide more volume than either flap alone which is advantageous, particularly in patients with sizable defects. The purpose of this study was to determine the average tissue volume that can be utilized from this chimeric flap. Methods CT Angiogram imaging studies exhibiting chimeric flap anatomy were reviewed over a 7-year period at a single institution utilizing Visage Version 7.1, a radiology picture archiving and communication system. This software was used to trace the flap pedicles and to capture estimated soft tissue volumes of each respective flap. Results A total of 31 patients, consisting of 52 lower extremity gracilis and PAP chimeric flaps, underwent tissue volume analysis. The average total volume of soft tissue supplied by the gracilis flap was found to be 70.21 cm3 (standard deviation [SD] = 26.99). The average volume of the PAP flap was 31.73 cm3 (SD = 26.12). The average total volume captured by the chimeric gracilis and PAP flap was 101.94 cm3 (SD = 62.40). Conclusion The potential soft tissue volume that can be harvested from a chimeric gracilis and PAP flap is significantly greater than solitary gracilis or PAP flaps. This chimeric flap may serve as a viable and advantageous reconstructive option for patients requiring large volume soft tissue coverage, particularly if other sizable options are not available.

Summary: Pseudoarthrosis is a severe complication of spinal fusion surgery with occurrence rates as high as 35%–40%. Current options of revision surgery to correct pseudoarthrosis frequently carry high failure rates and risk of developing junctional kyphosis. Pedicled vascularized bone grafts (VBGs) are an innovative approach to boost spinal fusion rates via improving structural integrity and increasing the delivery of blood to the donor site. This versatile technique can be performed at different spinal levels without additional skin incisions and with minimal added operative time. Here we present the first bilateral rib and iliac crest VBG spinoplastic surgery performed to augment spinal fusion in a 68-year-old woman with distal junctional kyphosis and severe positive sagittal balance with low back and neck pain and significant difficulty standing upright. The patient had history of multiple spinal operations with preoperative CT imaging demonstrating loosening and pull out of L3 and fracture of L2 screws. She underwent two-stage surgical treatment involving anterior lumbar interbody fusion L3-S1 followed by removal of hardware, T4 to pelvis fusion with L2-3 prone lateral interbody fusion, and T11-S1 posterior column osteotomies. The surgery was augmented by bilateral rib and iliac crest VBGs performed by plastic surgery. At three-month follow-up the patient demonstrated functional improvement, being able to maintain upright posture and walk; was satisfied with the result of the surgery; and demonstrated no graft-related complications. In conclusion, utilization of pedicled VBGs is a novel, promising approach to augment spinal surgery in high risk patients.

Background: Forehead contouring can be a component of facial feminization surgery (FFS). Its complications have been rarely reported on and are often described as “hypothetical.” Methods: A case report of complications from forehead contouring resulting in frontal osteomyelitis and sinusitis. Results: A female patient presented with frontal osteomyelitis, sinusitis, and forehead contour deformity after a type III forehead contouring surgery. She had failed prior treatment including oral antibiotics, IV antibiotics, revision sinus surgery, and revision nasal surgery. For definitive treatment, she underwent an anterior table resection, sinus obliteration with bony contouring, and pericranial flap. Conclusions: Forehead contouring represents a recent significant advancement in FFS and gender-affirming therapy. Descriptions of complications and their management are important when novel therapies such as FFS are introduced. This case demonstrates complications from type III forehead contouring including osteomyelitis, frontal sinusitis, and forehead deformity.

Abstract Goals/Purpose Perioperative management of estradiol therapy varies considerably among plastic surgeons performing aesthetic surgeries. This study aimed to review available literature regarding perioperative management of estradiol therapy in aesthetic surgery patients, and the risk it poses for developing VTE in the perioperative period. Methods/Technique A literature search was performed using online databases to identify studies evaluating VTE in aesthetic surgery patients taking oral contraceptives (OCPs) or hormone replacement therapy (HRT), and transgender patients on feminizing hormone therapy undergoing non-flap feminization surgery (facial feminization and breast augmentation procedures). Reported outcomes were extracted from these studies and summarized. Results/Complications A systematic review of the literature yielded 225 studies. Five of these studies met inclusion criteria. One study that was excluded, referenced an article that met inclusion criteria, which was ultimately included in our review for a total of six studies, representing 3,635 patients. Conclusion Data regarding perioperative management of estrogen therapy is limited in the literature, and standardized guidelines for aesthetic surgery patients have not been elucidated. This has led to inconsistencies in how estrogen is managed for elective, cosmetic procedures. Further research is needed to determine standardized practice guidelines. In the meantime, case-by-case evaluation of surgical appropriateness should continue. Surgeons should also consider risk-mitigating strategies, such as a focus on patient education, more intentional patient questioning regarding estrogen-containing product use, a preoperative coagulability workup for patients with a personal or family history indicative of possible coagulopathy, and specialty-wide efforts to create an aesthetics database and evidence-based guidelines.

Background: Research regarding financial trends in craniofacial trauma surgery is limited. Understanding these trends is important to the evolvement of suitable reimbursement models in craniofacial plastic surgery. The purpose of this study was to evaluate the trends in Medicare reimbursement rates for the top 20 most utilized surgical procedures for facial trauma. Methods: The 20 most commonly utilized Current Procedural Terminology (CPT) codes for facial trauma repairs in 2018 were queried from The National Summary Data File from the Centers for Medicare & Medicaid Services (CMS). Reimbursement data for each procedure was then extracted from The Physician Fee Schedule Lookup Tool. Changes to the United States consumer price index (CPI) were used to adjust all gathered data for inflation to 2021 US dollars (USD). The average annual and the total percent change in reimbursement were calculated for the included procedures based on the adjusted trends from the years 2000 to 2021. Results: From 2000 to 2021, the average reimbursement for all procedures decreased by 16.6% after adjusting for inflation. Closed treatment of temporomandibular joint dislocation and closed treatment of nasal bone fractures without manipulation demonstrated the greatest decrease in mean adjusted reimbursement at −48.7% and −48.3%, respectively, while closed treatment of nasal bone fractures without stabilization demonstrated the smallest mean decrease at −1.4% during the study period. Open treatment of nasal septal fractures with or without stabilization demonstrated the greatest increase in mean adjusted reimbursement at 18.9%, while closed treatment of nasal septal fractures with or without stabilization demonstrated the smallest increase at 1.2%. The average reimbursement for all closed procedures in the top 20 decreased by 19.3%, while that for all open procedures decreased by 15.5%. The adjusted reimbursement rate for all top 20 procedures decreased by an average of 0.8% each year. Conclusions: To the best of our knowledge, this is the first study to comprehensively evaluate trends in Medicare reimbursement for facial trauma surgical repairs. Adjusting for inflation, Medicare reimbursement for the top 20 most commonly utilized procedures has largely decreased from 2000 to 2021. Consideration of these trends by surgeons, hospital systems, and policymakers will be important to assure continued access to meaningful surgical facial trauma care in the United States.
