Navigating the Complexities of Radiation Injuries: Therapeutic Principles and Reconstructive Strategies

Radiation injuries, particularly those resulting from therapeutic or accidental exposure, present complex challenges for medical management. These injuries can manifest localized skin damage or extend to deeper tissues, presenting as various clinical entities that require treatment strategies, ranging from conservative management to complex surgical interventions. Radiation treatment constitutes a fundamental component of neoplastic management, with nearly two out of three oncological instances undergoing it as an element of their therapeutic strategy. The therapeutic approach to radiation injury consists of expanding prophylactic measures while maintaining the efficacy of treatment, such as conservative treatment or local debridement followed by reconstruction. The armamentarium of reconstructive methods available for plastic surgeons, from secondary healing to free tissue transfer, can be successfully applied to radiation injuries. However, the unique pathophysiological changes induced by radiation necessitate a careful and specialized approach for their application, considering the altered tissue characteristics and healing dynamics. The therapeutic strategy is guided by both the severity and progression of the injury, with the primary aim of restoring functionality and aesthetic aspects while simultaneously minimizing the risk of complications. This paper explores the various conditions encompassed by the term “radiation injury,” reviews both non-surgical and surgical therapeutic strategies for managing these injuries, and highlights the unique challenges associated with treating irradiated tissues within specific oncological contexts.

Impact of Physician Specialty on Treatment Costs of Invasive Melanoma

Introduction: Melanoma is a deadly type of skin cancer that develops from melanocytes and can manifest on the skin or other regions of the body. Its incidence is increasing rapidly, with approximately 100,000 diagnoses and 7000 deaths per year in the US alone. We conducted a cross-sectional study with the aim of determining an association between the cost of care for invasive melanoma and the specialty involved in the treatment to adequately guide future treatment. Methods: We analyzed data from 3817 patients (2013–2018) using the Florida inpatient/outpatient dataset, CMS cost reports, and the National Plan and Provider Enumeration System. Covariates included age, sex, race/ethnicity, insurance type, region, county rurality, the number of procedures, the comorbidity index, obesity, metastatic cancer presence, hospital size, and physician volume. Multivariable mixed linear regression was used to analyze the data, and the cost was adjusted to the 2019 USD. Results: Dermatology had the largest decrease in the overall and outpatient costs compared to general surgery, followed by plastic surgery. The inpatient costs for dermatology and plastic surgery were lower than those for general surgery, but not significantly so. Conclusions: The costs associated with surgical procedures may vary depending on the specialty of the physician treating the patient. Dermatology was associated with lower treatment costs for invasive melanoma compared to other specialties, indicating that physician specialty influences the cost of care.

Cranioplasty With Hydroxyapatite Implants: A Multidisciplinary Approach of Neurosurgeon and Plastic Surgeons to Improve Surgical Technique and Clinical Outcome.

Cranioplasty using Hydroxyapatite prosthesis is a conceptually simple procedure, but it may harbor several challenges for the surgeons. Several papers in the literature deal with cranioplasty using porous hydroxyapatite. The results are not homogeneous both because of the variability of the patients treated but also because Hydroxyapatite requires a more careful surgical technique to achieve maximum performance. The aim of the present study is to offer an insight of a single institution, multidisciplinary experience with custom-made Hydroxyapatite cranioplasty with surgical tips and tricks based on personal opinion and literature evidence. We will provide an overview of all the fundamental steps we believe to be useful to optimize surgical outcomes, including preoperative planning of cranioplasty; as cranioplasty flap/soft tissue coverage planning, infectious prophylaxis, patient positioning, incisional patterns, tissue dissection, primary bone demolition, and preparation of the craniectomy margins before implant positioning. The authors will also discuss methods for dural suspension, implant fixation and anchorage, margins polishing, drainage, suturing, and dressing. Cranioplasty using hydroxyapatite prosthesis is a valuable alternative for skull reconstruction with heterologous implants, and in our opinion a multidisciplinary approach integrating plastic surgeons and neurosurgeons' specific skills can facilitate surgical planning, reducing complications and allowing to achieve better functional and aesthetic results.

Optimizing Myelomeningocele Repair: Assessing the Role of Synthetic Acellular Dermal Regeneration Templates in Complex Closures.

Myelomeningoceles threaten newborns with central nervous system infectious risk. While some myelomeningoceles can be repaired fetally, limited donor tissue in newborns makes covering a substantial defect challenging. This study evaluated the effectiveness of acellular dermal regeneration templates (ADRT) in safely healing refractory myelomeningoceles. Seven myelomeningocele repair cases using ADRT (Integra LifeSciences, Plainsboro, NJ) at an academic children's hospital from April 2020 to June 2023 were reviewed. Patients had unsuccessful closure attempts through fetoscopic, postnatal, or revision surgeries by neurosurgery and plastic surgery, leading to complications that required ADRT to protect the dural repair and promote quicker granulation. The case series included 3 male and 4 female patients, with a median delivery age of 37 weeks (IQR: 33-37). Three underwent fetoscopic repairs, and 4 had postnatal repairs within 48 hours of birth. Six patients required ADRT placement due to failed primary repair. One patient failed fetoscopic closure and required immediate ADRT placement following an emergent cesarean delivery. The median wound size covered was 12cm2 (range, 4-20cm2), and the median hospital stay was 84 days (IQR: 43-105). Three weeks post-ADRT placement, 4 patients showed healthy granulation tissue, and the external silicone layer was removed. Three patients needed additional ADRT for complete wound coverage and successful granulation. After granulation, all wounds eventually epithelialized by secondary intention, with no postoperative infection or wound dehiscence observed. ADRT can aid in wound healing and protect dural repair in myelomeningoceles, offering a viable option for complex or failed primary closures with limited donor tissue.

Vascular Labeling of Extracranial Head and Neck Vessels Using Silicone Dye Injection: An Effective Method for Cadaver-Based Facial Surgery Training

Abstract Background Silicone dye injection is a well-described technique for studying vascular anatomy. Plastic surgeons routinely participate in cadaveric workshops and are involved in the preparation of vascular-labeled cadavers. However, sparse literature is available on dye studies of extracranial head and neck vessels, even with anatomists, and the preparation of these cadavers is a daunting task. Materials and Methods In this study, we describe a straightforward technique of silicone dye injection for extracranial head and neck vasculature and its application for filler injection training and other plastic surgical procedure demonstrations on cadavers. We used six soft-embalmed cadavers. The common carotid arteries and internal jugular veins were cannulated with infant feeding tubes. The vessels that could lead to dye extravasation into intracranial vessels and upper limbs were ligated. The vasculature was irrigated with water and then injected with color-coded silicone dyes (red: arterial; blue: venous). The solvent-to-catalyst ratios were varied to identify the ideal combination. Injected specimens were dissected 24 hours later to identify the staining quality. Results A clear demarcation of the extracranial head and neck vasculature in all cadavers was seen. The best solvent-to-catalyst ratio was identified in cadavers with the best staining of both large and small-sized blood vessels (<1 mm) with no dye spillage from arteries to the veins. Conclusion Silicone dye injection with the described technique can give excellent and predictable results. The technique also uses less quantity of dye, and the intracranial structures are spared, which can be used for other studies; hence, there is more economical utilization of cadavers.

Multidisciplinary Treatment of Hemifacial Microsomia: Several Clinical Cases

Hemifacial microsomia is the second most common congenital anomaly of the craniofacial region. Hemifacial microsomia is characterised by unilateral hypoplasia of the ear. Treatment of this condition depends on the severity of the lesion. The treatment of hemifacial microsomia must be carried out by a multidisciplinary group of professionals familiar with this pathology, including plastic surgeons, parapsychologists, orthodontists, and paediatricians. In hemifacial microsomia, microtia is usually accompanied by alterations of the middle ear. Since the ear develops embryonically from the first and second branchial arches, the facial areas that also develop from these embryonic origins are usually affected to a greater or lesser degree, including through hypoplasia of the jaw, maxilla, zygomatic bones, and temporal bone, among others. Although jaw hypoplasia is the most evident deformity in craniofacial microsomia, microtia is the alteration that often has the greatest aesthetic impact on patients. Alterations in dentition are also common, typically presenting as a cephalad inclination of the anterior occlusal plane of the maxilla and mandible on the affected side. This study aims to review the surgical approach and evaluate the results of a paediatric case of hemifacial microsomia. Hemifacial microsomia is present at birth, and successful reconstruction is essential for the correct integration of such infantile patients into society. Multiple facial asymmetries as well as neonatal onset are a challenge for reconstructive surgery, and the importance of multidisciplinary treatment in these patients must be emphasised.

Pediatric Reconstruction of Full-Thickness Dog Bite Scalp Avulsion with a Combination of Acellular and Matrix Products: A Case Report

The reconstruction of large full-thickness scalp injuries represents a great challenge in pediatric plastic surgery. Epidermal–dermal substitutes come to the rescue when traditional surgical strategies are not suitable. Recently, the new Integra MicroMatrix UBM particulate has arisen on the market. This is an extracellular matrix derived from the porcine urinary bladder matrix (UBM) in which the particulate structure provides close contact to the wound bed. We present the concomitant application of Integra DRT and MicroMatrix for the reconstruction of a full-thickness subtotal scalp defect in a child mauled by a dog.

Trends in Medicare Reimbursement for Gender-Affirming Procedures.

Medicare reimbursement rates are essential knowledge for gender-affirming plastic surgeons. The goal of this project was to examine trends in Medicare reimbursement rates for gender-affirming plastic surgery procedures from 2007 to 2020. Changes in reimbursement rates were measured for 35 commonly used gender-affirming procedure CPT codes from 2007 to 2020 adjusted for inflation to the 2020 US dollar value. The Unadjusted Percent Change in Consumer Price Index (CPI) was calculated using data from the US Bureau of Labor Statistics. Reimbursement rates were adjusted for inflation using the CPI for each year. Student t test was utilized for mean comparisons. Mean percent change in reimbursement rates was +16.01% while the percent change in CPI was +27.45%. Comparison between rate change of inflation versus rate change in adjusted medical reimbursement was significantly higher in the inflation group (P < 0.0001). Inflation adjustments for the Compound Annual Growth Rate was negative (-0.76%). The adjusted total percent change was also calculated at an average of -8.97%. This is the first study evaluating trends in Medicare reimbursement rates for commonly selected gender-affirming procedures in the United States. After adjusting for inflation, Medicare reimbursement rates for all gender-affirming surgeries analyzed declined from the years 2007 to 2020 compared to expected inflation base. Increased consideration of these trends will be important for US policymakers, hospitals, and surgeons to ensure ease of access to gender-affirming care for transgender individuals.

Investigating the correlation of hip circumference to cardiovascular disease and type-2 diabetes using Mendelian randomization.

This study aimed to assess the correlation between hip circumference (HC) and the risk of cardiovascular disease (CVD) and type 2 diabetes mellitus using Mendelian randomization (MR) to overcome observational study limitations. MR analysis utilized genetic variation from the MR Base in a two-sample analysis. Three methods were employed: MR-Egger regression, weighted median estimator, and inverse variance weighting (IVW). Data was acquired from MR Base, a platform summarizing genome-wide association study (GWAS) data for MR research. Publicly available summary statistics datasets from GWAS meta-analyses were used, with HC and HC adjusted for body mass index (BMI) as exposures. Data for CVD and type 2 diabetes mellitus were obtained as outcomes. Results indicated a positive causal relationship between HC and CVD (IVW: P = 1.84e-07, OR: 1.37, 95% CI: 1.22-1.54) as well as type 2 diabetes mellitus (IVW: P = 0.04, OR: 1.62, 95% CI: 1.02-2.56), independent of BMI. However, HC after BMI adjustment showed no significant causal relationship with CVD (IVW: P = 0.05, OR: 1.09, 95% CI: 1.00-1.19) and exhibited a negative association with type 2 diabetes mellitus (IVW: P = 0.00, OR: 0.76, 95% CI: 0.66-0.88), suggesting a protective effect against type 2 diabetes mellitus. After adjusting for BMI, adipose tissue concentrated in the hip region showed a protective effect against type 2 diabetes mellitus but not against CVD. These findings offer insights into diabetes prevention and treatment strategies, and may inform plastic surgery procedures. Further research is needed to validate these findings and explore underlying mechanisms.

Therefore, this paper seeks to address possible concerns and questions about AI in plastic surgery while offering a realistically neutral insight. Additionally, fundamental ethical and legal principles will be discussed, as well as possible “rules of the game” for the application and integration of AI in surgery. Innovations in this field are often hailed as miracles, making it crucial to evaluate them critically and objectively. Although progress in AI cannot and should not be halted, it is important to strengthen the trained approach and always look at the whole picture.

Integrating AI into Breast Reconstruction Surgery: Exploring Opportunities, Applications, and Challenges.

Background: Artificial intelligence (AI) has significantly influenced various sectors, including healthcare, by enhancing machine capabilities in assisting with human tasks. In surgical fields, where precision and timely decision-making are crucial, AI's integration could revolutionize clinical quality and health resource optimization. This study explores the current and future applications of AI technologies in reconstructive breast surgery, aiming for broader implementation. Methods: We conducted systematic reviews through PubMed, Web of Science, and Google Scholar using relevant keywords and MeSH terms. The focus was on the main AI subdisciplines: machine learning, computer vision, natural language processing, and robotics. This review includes studies discussing AI applications across preoperative, intraoperative, postoperative, and academic settings in breast plastic surgery. Results: AI is currently utilized preoperatively to predict surgical risks and outcomes, enhancing patient counseling and informed consent processes. During surgery, AI supports the identification of anatomical landmarks and dissection strategies and provides 3-dimensional visualizations. Robotic applications are promising for procedures like microsurgical anastomoses, flap harvesting, and dermal matrix anchoring. Postoperatively, AI predicts discharge times and customizes follow-up schedules, which improves resource allocation and patient management at home. Academically, AI offers personalized training feedback to surgical trainees and aids research in breast reconstruction. Despite these advancements, concerns regarding privacy, costs, and operational efficacy persist and are critically examined in this review. Conclusions: The application of AI in breast plastic and reconstructive surgery presents substantial benefits and diverse potentials. However, much remains to be explored and developed. This study aims to consolidate knowledge and encourage ongoing research and development within the field, thereby empowering the plastic surgery community to leverage AI technologies effectively and responsibly for advancing breast reconstruction surgery.

Plastic Surgery Contributions to the World Wars: Historical Foundations for Modern Craniofacial Techniques.

Plastic surgery played a crucial role during the World Wars. Surgeons dedicated their careers to reconstructing facial injuries and residual deformities incurred during combat. Times of unprecedented trauma led to rapid innovation in plastic surgery, with invaluable impact on practice today. Pioneers such as Harold Gillies are well-known for their work. There are numerous additional contributors who deserve wider recognition. A literature review was performed to identify key surgeons who treated soldiers' craniofacial injuries during World Wars I and II. Biographical information, country of practice, and technical contributions to plastic surgery were compiled. Nineteen plastic surgeons were identified who contributed significantly to craniofacial surgery during the World Wars. These surgeons were: Albéric Pont, Archibald Mcindoe, Arthur Mowlem, Harold Gillies, Hippolyte Morestin, James Barrett Brown, Jaques Joseph, Johannes Esser, John Staige Davis, John Reese, Otto Lanz, Paul Tessier, Robert Ivy, Suzanne Blanche Gros Noël, Thomas Kilner, William Kelsy Fry, Varaztad H. Kazanjian, Vilray P. Blair, and Vladimir Petrovich Filatov. Fourteen were active during WWI. Nine were active during WWII. Notable technical developments were made in maxillofacial fracture fixation, bone grafting, rhinoplasty, dental prosthetics, flap-based coverage, skin grafting, and burn reconstruction. Plastic surgeons played an unheralded role in managing the disfiguring craniofacial injuries of World Wars I and II. By treating tens of thousands of war victims, these surgeons contributed not only to the rehabilitation of soldiers but also to the advancement of craniofacial surgery and the establishment of plastic surgery as a distinct subspecialty.

Dorsal Preservation Rhinoplasty-the Perspective of "Preservers" Versus "Structural" Surgeons.

The objective of this study was to describe the surgeons who have incorporated dorsal preservation (DP) into their practice and their techniques. An anonymous form reviewed by the Evidence-Based Rhinoplasty Research Group board was shared on its Telegram group. The study population was divided into three groups based on their answers: "Preservers," "Mainly Structural," and "Structural exclusively." This study included the answers of 145 worldwide surgeons. DP was more common among plastic surgeons than otolaryngologists/facial plastic surgeons; DP techniques were mostly preferred by surgeons with 10-20 years of experience, while structural techniques were mostly preferred by surgeons with > 20 years of experience; 50.8% of the surgeons who prefer DP techniques use it in more than 90% of primaries; surface techniques (ST) have been more used, mainly by surgeons who prefer structural techniques (p < 0.001). ST were considered more stable (p < 0.001), more predictable (p < 0.001), and shorter learning curve (p < 0.001). Many surgeons using DP still perform structural rhinoplasty. The most cited concern was hump persistence/recurrence. DP rhinoplasty is gaining acceptance, and ST are favored for their perceived short learning curve, stability, and predictability. However, concerns about hump recurrence cause some to continue using structural methods alongside DP.

Utilization of Text-to-Image Artificial Intelligence Model in Preoperative Counseling for Lip Lift Procedures

Summary: Text-to-image models powered by artificial intelligence (AI) offer a promising tool for enhancing patients' comprehension of cosmetic surgery outcomes and providing personalized visual forecasts of their appearance after the procedure. This study explores the efficacy of text-to-image AI models, specifically DALL·E2, in improving preoperative counseling for patients undergoing lip lift procedures. Preoperative photographs of four patients, who had given their consent, were processed using DALL·E2, which allows users to modify specific areas of an image and input text descriptions to visualize anticipated changes. We successfully demonstrated the ability of DALL·E2 to generate accurate visual predictions within a short timeframe of two minutes. Selected images provided realistic expectations of the postoperative appearance, aiding in better patient understanding and expectation management.

Beyond CDC-Defined Surgical Site Infection: Factors Associated with Antibiotic Prescription After Breast Operation.

Background: Most studies on surgical site infections (SSIs) use the US Centers for Disease Control and Prevention (CDC) guidelines, which excludes inflammation or cellulitis without fever. The aim of this study was to evaluate antibiotic prescription trends in the post-operative period among patients undergoing breast operation. We explore the outcomes of patients receiving antibiotic agents outside of the CDC-defined SSI. Patients and Methods: A retrospective review of patients undergoing breast operation from January 2021 to May 2021 was conducted. Solely reconstructive and cosmetic cases were excluded. The primary outcome was the prevalence of antibiotic prescription in the absence of CDC-defined SSI, excluding routine prophylactic antibiotic agents, with analysis of associated factors. Results: A total of 754 breast surgical procedures were included. Seventy-seven patients (10.2%) were prescribed outpatient antibiotic agents. CDC-defined SSI occurred in 5.3% (n = 40), mostly involving tissue expander/implant-based reconstruction (47.5%, n = 19). However, 37 (4.9%) did not progress to meet the CDC criteria for SSI. Patients prescribed outpatient antibiotic agents without CDC-defined SSI did not have increased rates of diabetes mellitus, obesity, or current smoking. These patients were more likely to have a surgical drain (48.6% vs. 28.4%, p = 0.02), plastic surgery involvement (32.4% vs. 18.0%, p = 0.048), and a post-operative seroma (32.4% vs. 8.1%, p < 0.001) and or or cellulitis (18.9% vs. 0%, p < 0.001). Conclusion: Patients are prescribed antibiotic agents after breast operation based on clinical judgment for indications other than CDC-defined SSI. Post-operative wound morbidity including seroma and cellulitis could be contributing to these antibiotic prescriptions. Further study is needed to determine whether providers are preemptively treating SSIs appropriately or over-treating non-infectious wound complications.

'Virtual Mentorship is a No-Brainer': The Application of a Virtual Mentorship Programme for Prospective Plastic Surgery Trainees.

Aims This study aimed to evaluate the effectiveness of a virtual mentorship programme in plastic surgery designed for medical students and foundation doctors in the United Kingdom. The programme sought to enhance understanding of common and emergency conditions, provide guidance on the application process for speciality training, and facilitate networking opportunities. Materials and methods The programme consisted of six sessions delivered via Microsoft Teams (Microsoft® Corporation, Redmond, WA) over a four-month period from May to August 2024. Participants completed online pre- and post-mentoring questionnaires. Wilcoxon signed-rank test was used to compare paired data responses. Results Ten participants completed both questionnaires; 90% were medical students, and 10% were foundation-year doctors. There was a significant increase in the understanding of common plastic surgery conditions and emergencies (p < 0.05), as well as improved knowledge of the application processes for core surgical training (p < 0.05) and higher speciality training (p < 0.05). Interest in the speciality significantly increased (p < 0.05), and participants were more likely to seek in-person mentorship (p < 0.05). The programme was well-received, with 100% rating it as 'excellent' or 'very good'. Conclusions The virtual mentorship programme effectively enhanced foundational knowledge, career preparation, and mentor-mentee relationships. Its implementation is recommended both alone and in combination with traditional face-to-face mentorship.

Contemporary role of the plastic and reconstructive surgeon in the outcome of female peripelvic defects after oncologic extirpation.

Reconstruction of female oncologic peripelvic defects is challenging due to complex anatomy, neoadjuvant chemoradiation, operative resection margins, and wound healing risks. Functional restoration requires thoughtful management focused on defect reconstruction and patient-reported outcomes. A retrospective chart review of peripelvic reconstruction in female patients at MD Anderson Cancer Center from 2016 to 2023. Data collected included the patient'scomorbidities, tumor characteristics, and reconstructive details. Complications were classified as nonoperative or operative within 30 days. Patient outcomes included hernia rates, sexual activity, and revision needs. In the study period, 164 patients underwent peripelvic defect reconstruction. Most had colorectal (57%), anal (17%), or gynecologic malignancies (10%). 83% had prior radiation. 33.3% had Class II or III obesity. The most common resection was open colorectal resection with partial vaginectomy (66%). Pedicled flaps (93%) were frequently used, mainly vertical rectus abdominis muscle (65%) and gracilis (11%). For multi-visceral resections, abdominal-based flaps were used in 95% of open casesand thigh-based flaps in 88.9% of robotic cases. 51% had formal abdominal wall repair. Complications occurred in 47%, with 9.1% needing surgery. Postoperative hernias were reported in 4.9%, with 3% requiring repair. Approximately 11% reported being sexually active at the last follow-up. Of those instructed on vaginal dilator therapy (42%), 24.6% were sexually active. Peri-pelvic soft tissue reconstruction in the oncologic population is safe. Operative complications and hernia rates are low. In robotic surgery, thigh-based flaps are increasingly used to reconstruct the peripelvic region. Return to sexual activity is higher in patients when given dilator therapy instruction.
