Modified Gritti-Stokes amputation: tips and tricks.

Major amputations of the lower extremity may be required after trauma and a variety of underlying diseases such as peripheral vascular disease, diabetes, and malignancies. The goal of any major amputation is an optimal functional result with a maximum limb length in combination with optimal wound healing. The preservation of the knee joint is essential for successful rehabilitation, and this is best achieved by the Burgess below-knee amputation (BKA). Whenever a BKA is not possible, the Gritti-Stokes amputation is our first choice. This technique mainly consists of a through-knee amputation with the creation of a pedicled patella flap consisting of the patella, patellar ligament, and overlying soft tissue. After osteotomy of the distal femur and resection of the articular surface of the patella, the anterior flap is rotated in order to cover the femur defect while performing a patellofemoral arthrodesis. The aim of this paper is to describe our surgical technique and experience with GSA and to point out the important steps of this procedure. In conclusion, GSA is an excellent surgical option for patients requiring major lower limb amputations where BKA cannot be considered. Particular attention must be paid to careful preoperative evaluation and optimization of comorbidities. A meticulous surgical technique is warranted, including atraumatic tissue handling and an optimal patellofemoral arthrodesis technique.

[Treatment of abdominal lipocutaneous excess in massive weight loss patients]. / Traitement de l'excès cutanéo-adipeux abdominal après perte de poids massive.

In massive weight loss patients, abdominal lipocutaneous excess is a frequently encountered complication with major psychological, medical and functional consequences. A wide variety of corrective techniques exists, each with its advantages and side effects, and the choice of the technique must be made in conjunction with the patient, taking into account his unique anatomy, his wishes and his risk factors, in order to obtain the best aesthetic result while minimising the per- and post-operative complications. Liposuction, if prudently executed with the correct technique, permits a further harmonisation of the body contour in zones not reached by the surgical correction, representing a very useful and efficient additional tool.

L'excès cutanéo-adipeux abdominal est une conséquence très fréquente chez les patients après une perte de poids massive, avec d'importantes répercussions psychologiques, médicales et fonctionnelles. Plusieurs techniques de correction des déformations existent, avec leurs avantages et complications spécifiques. Le choix doit être individualisé et partagé avec le patient sur la base de ses caractéristiques anatomiques uniques, de ses souhaits et de ses facteurs de risque, pour un résultat esthétique optimal avec une minimisation des complications. La liposuccion, lorsqu'elle est effectuée de façon prudente et selon les règles de l'art, est un outil additionnel très efficace pour une harmonisation des contours dans les zones non directement ciblées par l'intervention choisie.

The Promise and Pitfalls of AI-Generated Anatomical Images: Evaluating Midjourney for Aesthetic Surgery Applications.

BACKGROUNDS: The rapid advancement of generative artificial intelligence (AI) systems, such as Midjourney, has paved the way for their use in medical training, producing computer-generated images. However, despite clear disclosures stating that these images are not intended for medical consultations, their accuracy and realism are yet to be thoroughly examined. METHODS: A series of requests were addressed to the Midjourney AI tool, a renowned generative artificial intelligence application, with a focus on depicting appropriate systemic anatomy and representing aesthetic surgery operations. Subsequently, a blinded panel of four experts, with years of experience in anatomy and aesthetic surgery, assessed the images based on three parameters: accuracy, anatomical correctness, and visual impact. Each parameter was scored on a scale of 1-5. RESULTS: All of images produced by Midjourney exhibited significant inaccuracies and lacked correct anatomical representation. While they displayed high visual impact, their unsuitability for medical training and scientific publications became evident. CONCLUSIONS: The implications of these findings are multifaceted. Primarily, the images' inaccuracies render them ineffective for training, leading to potential misconceptions. Additionally, their lack of anatomical correctness limits their applicability in scientific articles. Although the study focuses on a single AI tool, it underscores the need for collaboration between AI developers and medical professionals. The potential integration of accurate medical databases could refine the precision of such AI tools in the future.

Orthoplastic limb reconstruction using free fibula flap after trauma: Outcomes from a retrospective European multicenter study.

BACKGROUND: Free vascularized fibula flap represents the gold standard vascularized bone graft for the management of segmental long bone defects after traumatic injury. The current study represents the largest retrospective multicenter data collection on the use of free fibula flap (FFF) for extremities' orthoplastic reconstruction after trauma aiming to highlight current surgical practice and to set the basis for updating current surgical indications. METHODS: The study is designed as a retrospective analysis of prospectively collected data between 2009 and 2021 from six European University hospitals. Patients who underwent fibula flap reconstruction after acute traumatic injury (AF) or as a late reconstruction (LF) after post-traumatic non-union of upper or lower limb were included. Only extra-articular, diaphyseal fracture were included in the study. Surgical data were collected. Time to bone healing and complications were reported as clinical outcomes. RESULTS: Sixty-two patients were included in the study (27 in the AF group and 35 in the LF group). The average patients' age at the time of the traumatic event was 45.3 ± 2.9 years in the AF group and 41.1 ± 2.1 years in the LF group. Mean bone defect size was 7.7 ± 0.6 cm for upper limb and 11.2 ± 1.1 cm (p = .32) for lower limb. Bone healing was uneventful in 69% of treated patients, reaching 92% after complementary procedures. Bone healing time was 7.6 ± 1.2 months in the acute group and 9.6 ± 1.5 months in the late group. An overall complication rate of 30.6% was observed, with a higher percentage of late bone complications in the LF group (34%), mostly non-union cases. CONCLUSIONS: FFF reconstruction represents a reliable and definitive solution for long bone defects with bone healing reached in 92% cases with a 8.4 months of average bone healing time.

Comparisons of the morbidities of a double gastrocnemius flap and a medial gastrocnemius flap in the orthoplastic reconstruction around the knee.

BACKGROUND: The pedicled gastrocnemius flap is commonly used to treat lower limb defects. Either the medial, lateral, or both heads can be used. When extended soft tissue defects are present, a double gastrocnemius (DG) flap may be used. However, no data of the additional donor site morbidity compared to a medial gastrocnemius (MG) flap are available. The aim of this study was to compare the donor site morbidity of a DG with that of a MG. METHODS: Patients with a soft tissue defect around the knee, treated with a gastrocnemius flap between 2018 and 2021 at the University Hospital of Lausanne and Bari, with a minimum follow-up of 12 months, were included. According to the size and the position of the defect, it was decided whether one (10 patients) or two (9 patients) heads of the gastrocnemius were necessary for the coverage. The mean age was 61 years (range 42-82) in DG, and 63 years (range 45-78) in MG. The average defect size was 89.8 cm2 in the DG group and 53.4 cm2 in the MG group. The etiologies were trauma (n = 10), infection (n = 7) and sarcoma (n = 2). A medial approach or a posterior midline approach was used for the harvesting of the gastrocnemius muscle. Once the flap was harvested, it was rotated and transposed anteriorly over the defect, either through a subcutaneous tunnel or by dividing the intervening skin bridge, depending on the soft tissue defect. A split-thickness skin graft was used to close the skin over the remaining exposed muscle flap. The active range of motion of the ankle and knee joints was measured. Muscle strength was assessed with a hand-held dynamometer and by the ability to stand on tiptoe. Physical function was evaluated through the Lower Extremity Functional Scale (LEFS). RESULTS: The two groups were homogeneous, with no significant difference in age, sex, and BMI. All flaps survived in both groups. Both groups showed lower values in strength and range of motion of the operated leg, when compared to contralateral side. In plantar flexion, this accounted for a reduction in MG by 3.8 ± 1.0 kg of strength and 8 ± 3° of ROM, and in DG by 4.7 ± 1.7 kg and 16 ± 4°, respectively. For knee flexion, the reduction in MG was 4.4 ± 0.6 kg and 16 ± 7°, while in DG 5.6 ± 1.0 kg and 28 ± 6°. In the MG group, 60% were able to stand on the tiptoe of the operated leg, as opposed to 0% in DG. The average LEFS score in DG was lower by 10.9 points (p < .05). Questions concerning running and jumping had a lower score in DG (p < .01). CONCLUSIONS: The harvesting of both gastrocnemii led to significant additional donor site morbidity compared to the harvesting of the medial gastrocnemius alone. However, the additional morbidity did not have an impact on activities of daily living and walking, even though it limited the ability to perform more demanding tasks such as running and jumping. Therefore, based on our study, the choice of a DG flap should be critically assessed in younger, more demanding patients.

Evaluation of modulation of immunity by lymph node transfer: A preliminary histological evidence in lymphedema patients.

BACKGROUND: The exact knowledge of the local biological and immunological effects of vascularized lymph node transfer (VLNT) continues to be an emerging science but a positive control positive control over infectious and immune-mediated processes is often advocated. Knowing the characterization of the inflammatory infiltrate associated with lymphedema, the aim of this paper is to verify the hypothesis that VLNT is able to modulate the inflammatory and immune microenvironment of lymphedematous tissue by evaluating any modification of the local inflammatory cell infiltrate. PATIENTS AND METHODS: A prospectively database of patients who received VLN transfer for lower extremity lymphedema between January 2018 and December 2020 was reviewed. Nine patients diagnosed with extremities' stage II secondary lymphedema were included, with a mean age of 55.3 (range 39-66 years) years. Gastroepiploic lymph node transfer was performed in all patients and transferred heterotopically. Full thickness 6-mm skin punch biopsies were obtained from all voluntary lymph node transfer patients at identical sites of the lymphedematous limb during the surgical procedure of VLNT (T0) and 1 year later (T1). Immunohistochemistry was performed using antibodies against the following markers: anti-CD3; anti-CD4; anti-CD8; anti-CD68. Data at T0 were compared to those at T1. RESULTS: Post-operative course was uneventful in all cases experiencing a significant reduction (almost a third) in terms of cellulitis episodes: The median duration of follow-up for patients was 28.3 months (range 12-40). The analysis of the density of the inflammatory cells as a whole revealed a significant reduction at T1 compared to T0. Specifically, CD3 expression levels turned from 16.36 ± 3.421 (cells/mm2 ) pre-operatively to 7.6 ± 1.511 (cells/mm2 ) post-operatively (p < .0001). CD4+ cells turned from 7.270 ± 3.421 (cells/mm2 ) at T0 to 4.815 ± 1.511 cells/mm2 at T1 (p = .0173). CD8 expression values decreased from 4.360 ± 3.421 (cells/mm2 ) to 2.753 ± 1.451 (cell/mm2 ) at T1 (p = .0003). Monocyte/macrophage marker CD68 varied from 8.208 ± 2.314 (cells/mm2 ) at T0 to 7.600 ± 1876 (cells/mm2 ) at T1 (p = .0003). CONCLUSION: VLNT decreases skin and subcutaneous tissues' infiltration of inflammatory cells, providing one explanation for the positive control of lymph node transfer procedure over infectious and immune-mediated processes.

Role of the Gastrocnemius Musculocutaneous with a Propeller Style Skin Flap in Knee Region Reconstruction: Indications and Pitfalls.

Background Soft tissue reconstruction around the knee area is still an open question, particularly in persistent infections and multiple reoperations scenario. Flap coverage should guarantee joint mobility and protection, even when foreign materials are implanted. The chimeric harvesting of the musculocutaneous gastrocnemius flap, based on the sural artery perforators, can extend its applicability in soft tissue reconstruction of the upper leg, overcoming the drawbacks of the alternative pedicled flaps. Methods A multicenter retrospective study was conducted enrolling patients who underwent to a pedicled, chimeric gastrocnemius musculocutaneous-medial sural artery perforator (GM-MSAP) or lateral sural artery perforator (GM-LSAP) flap for knee coverage in total knee arthroplasty (TKA) recurrent infections and oncological or traumatic defects of the upper leg from 2018 to 2021. Outcomes evaluated were the successful soft tissue reconstruction and flap complications. Surgical timing, reconstruction planning, technique, and rehabilitation protocols were discussed. Results Twenty-one patients were included in the study. Nineteen GM-MSAPs and 2 GM-LSAPs were performed (soft tissue reconstruction in infected TKA [12], in infected hardware [4], and in oncological patients [5]). Donor site was closed primarily in 9 cases, whereas a skin graft was required in 12. Flap wound dehiscence (1), distal flap necrosis (1), distal necrosis of the skin paddle (1), and donor site infection (1) were the encountered complications. Flap reraise associated to implant exchange or extensive debridement was successful without requiring any further flap surgery. Conclusion The propeller-perforator GM-MSAP offers qualitative defect coverage and easiness of multiple flap reraise due to skin availability and its laxity.

FastSkin® Concept: A Novel Treatment for Complex Acute and Chronic Wound Management.

Successful treatments for acute and chronic skin wounds remain challenging. The goal of this proof-of-concept study was to assess the technical feasibility and safety of a novel wound treatment solution, FastSkin®, in a pig model. FastSkin® was prepared from skin micrografts patterned in blood using acoustic waves. Upon coagulation, the graft was transferred on a silicone sheet and placed on wounds. Six full-thickness wounds were created at the back of two pigs and treated with either FastSkin®, split-thickness skin graft (positive control), a gauze coverage (negative control, NC1), or blood patterned without micrografts (negative control, NC2). Silicone sheets were removed after 7, 14, and 21 days. Wound healing was monitored for six weeks and evaluated macroscopically for re-epithelialization and morphometrically for residual wound area and wound contraction. Tissue regeneration was assessed with histology after six weeks. Re-epithelialization was faster in wounds covered with FastSkin® treatments compared to NC2 and in NC2 compared to NC1. Importantly, an enhanced collagen organization was observed in FastSkin® in contrast to NC treatments. In summary, two clinically approved skin wound treatments, namely micrografting and blood clot graft, were successfully merged with sound-induced patterning of micrografts to produce an autologous, simple, and biologically active wound treatment concept.

Abdominal-Based Microsurgical Breast Reconstruction: How to Inset the Flap to Maximize the Aesthetic Result-A Systematic Review.

Nowadays, the ultimate goal of microsurgical breast reconstruction is not merely the effective transfer of vascularized tissue but the achievement of a natural, symmetric appearance. The aim of this present study was to systematically summarize the published evidence on abdominal-based free flap inset for breast reconstruction in order to provide principles and classification that could guide the surgeon in choosing the most appropriate inset technique based on patient and flap characteristics. A comprehensive review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, looking for articles on the insetting technique for free flap breast reconstruction. After screening 306 publications, 24 papers (published from 1994 to 2020) were included in the study. We identified four main breast anatomical features on which the papers reviewed focused when describing their insetting technique: breast width, breast ptosis, breast projection, and upper pole fullness. Patient body type, type of mastectomy, and reported complications are also discussed. Flap shaping and inset during breast reconstruction are fundamental steps in any reconstructive procedure. Despite the low evidence in the current literature, this systematic review provides a framework to guide the surgeon's decision-making and optimize the aesthetic outcomes of abdominal-based free flap breast reconstruction.

Human platelet lysate stimulates neurotrophic properties of human adipose-derived stem cells better than Schwann cell-like cells.

BACKGROUND: Trauma-associated peripheral nerve injury is a widespread clinical problem causing sensory and motor disabilities. Schwann cells (SCs) contribute to nerve regeneration, mainly by secreting nerve growth factor (NGF) and brain-derived neurotrophic factor. In the last years, adipose-derived stem cells (ASCs) differentiated into SCs (SC-ASCs) were considered as promising cell therapy. However, the cell trans-differentiation process has not been effectively showed and presents several drawbacks, thus an alternative approach for increasing ASCs neurotrophic properties is highly demanded. In the context of human cell-based therapies, Good Manufacturing Practice directions indicate that FBS should be substituted with a xenogeneic-free supplement, such as Human Platelet Lysate (HPL). Previously, we demonstrated that neurotrophic properties of HPL-cultured ASCs were superior compared to undifferentiated FBS-cultured ASCs. Therefore, as following step, here we compared the neurotrophic properties of differentiated SC-like ASCs and HPL-cultured ASCs. METHODS: Both cell groups were investigated for gene expression level of neurotrophic factors, their receptors and neuronal markers. Moreover, the expression of nestin was quantitatively evaluated by flow cytometry. The commitment toward the SC phenotype was assessed with immunofluorescence pictures. Proteomics analysis was performed on both cells and their conditioned media to compare the differential protein profile. Finally, neurotrophic abilities of both groups were evaluated with a functional co-culture assay, assessing dorsal root ganglia survival and neurite outgrowth. RESULTS: HPL-cultured ASCs demonstrated higher gene expression of NGF and lower expression of S100B. Moreover, nestin was present in almost all HPL-cultured ASCs and only in one quarter of SC-ASCs. Immunofluorescence confirmed that S100B was not present in HPL-cultured ASCs. Proteomics analysis validated the higher expression of nestin and the increase in cytoskeletal and ECM proteins involved in neural regeneration processes. The co-culture assay highlighted that neurite outgrowth was higher in the presence of HPL-ASCs or their conditioned medium compared to SC-ASCs. CONCLUSIONS: All together, our results show that HPL-ASCs were more neurotrophic than SC-ASCs. We highlighted that the HPL triggers an immature neuro-induction state of ASCs, while keeping their stem properties, paving the way for innovative therapies for nerve regeneration.

Meek Micro-Skin Grafting and Acellular Dermal Matrix in Pediatric Patients: A Novel Approach to Massive Extravasation Injury.

(1) Background: Extravasation injuries in pediatric patients can lead to significant harm if they are not promptly diagnosed and treated. However, evidence-based standardization on extravasation management remains limited, particularly for extensive wound necrosis. This case report presents the management of an 8-week-old premature patient with an extensive extravasation injury involving the right forearm and dorsum of the hand. (2) Methods: The patient was evaluated by a multidisciplinary team in our Neonatal Intensive Care Unit. Surgical intervention involved the debridement of necrotic tissues, followed by temporary coverage with an acellular dermal matrix. Definitive coverage was achieved through Meek micrografting after three weeks. Physical therapy was provided with pre- and post-rehabilitation range of motion assessed using goniometric measurements. Scar quality was evaluated using the Vancouver Scar Scale. (3) Results: The engraftment rate of the Meek micrografts was 93%, with 16 out of 226 micrografts lost. The patient achieved a Vancouver Scar Scale score of 6, indicating a moderate degree of scarring. Significant improvements in elbow, wrist, and finger joint range of motion were observed at a 1-year follow-up. (4) Conclusions: Close observation and heightened awareness of extravasation risks by trained personnel are crucial. Meek micrografting combined with dermal substitute coverage represents an innovative approach to managing extravasation wounds in pediatric patients.

Efficacy of breast reconstruction in elderly women (>60 years) using deep inferior epigastric perforator flaps: A comparative study.

BACKGROUND: The indications for microsurgical breast reconstruction remain debated, particularly concerning the safety of deep inferior epigastric perforator (DIEP) flaps in elderly women. Free tissue transfer still carries a risk of perioperative morbidity and mortality in elderly patients. We conducted this comparative study to clarify this issue. METHODS: This retrospective cohort study included all unilateral DIEP breast reconstructions performed at a single institution. Patients were divided into two groups based on age: an elderly (60 years or older) and a non-elderly cohort (younger than 60 years). Demographic and comorbidity data were secondary predictor variables. The primary outcomes were complete flap loss, partial flap loss, and the need for flap re-exploration. The secondary outcomes included surgical site occurrences, such as wound healing-related complications, seroma, and others. RESULTS: We included 214 flaps, 177 in the non-elderly and 37 in the elderly cohort. Elderly women had slightly higher comorbidity rates than those of non-elderly women, although these differences were not statistically significant. BMI was significantly lower in elderly women than in non-elderly women. The incidence of total or partial flap loss did not differ significantly between the two cohorts (2.7% vs 1.1%, p = 0.459% and 0.0% vs 5.1%, p = 0.161), nor did the flap re-exploration (8.1% vs 10.1%, p = 0.937). Similarly, postoperative complication rates did not differ significantly between the two groups (45.9% vs 61.8%, p = 0.074). On logistic regression, being elderly was not a risk factor for complete flap loss, nor for any complications. The overall success rate for the non-elderly cohort was 98.7%, whereas that for the elderly cohort was 97.3%. CONCLUSIONS: Microsurgical breast reconstruction using DIEP is safe in elderly patients, as it achieves outcomes and complications rates comparable to those observed in a younger population. Patients should not be denied DIEP flaps because of their age alone.

Time to return to work after total trapeziometacarpal prosthesis.

OBJECTIVES: This study assessed return to work and prosthesis survival after trapeziometacarpal prosthesis surgery. MATERIAL AND METHODS: A multicenter retrospective study was carried out on patients operated on between 2002 and 2020. All working patients who had undergone trapeziometacarpal prosthesis surgery were included. Return to work was defined as resuming the same full-time position. Postoperative events and their specific treatment and failure to return to work were reported. RESULTS: 240 prostheses in 211 patients were included. The complications rate was 7.5%, with 97% prosthesis survival. 94.3% of patients returned to work, at a mean 48 days (range, 29-210 days; SD, 22.7 days), with no significant difference according to age. Twelve patients did not return to work, half of whom because of prosthetic complications. CONCLUSION: Trapeziometacarpal arthroplasty enables most patients to return to work within 6 weeks. In this series, the prosthetic survival rate was 97%.

In vivo evaluation of Adipose-Derived Stem Cells (ADSCs) using Nanofat technique and chitosan conduit for peripheral nerve defect repair.

INTRODUCTION: Nerve autograft is the gold standard for reconstruction of peripheral nerve loss. The alternative is the interposition of a synthetic regeneration conduit. The purpose of the study was to evaluate the in vivo feasibility and interest of Adipose-Derived Stem Cells (ADSCs) using the Nanofat technique and chitosan conduit for peripheral nerve defect repair. MATERIAL AND METHODS: In vivo, after the creation of a 10 mm defect of the sciatic nerve, 2 groups were defined according to the nerve repair in rats: "chitosan" group (n = 10) and "chitosan and ADSCs" group (n = 10) with a clinical and paraclinical evaluation at 7 weeks. RESULTS: The in vivo results seem to show that the adjunction of ADSCs was favorable clinically, histologically and functionally compare to a chitosan reconstruction alone. DISCUSSION: Peripheral nerve repair with defect using a chitosan conduit associated with ADSCs would constitute a surgical alternative in a single surgical step.

Mesenchymal Stem Cells in Nerve Tissue Engineering: Bridging Nerve Gap Injuries in Large Animals.

Cell-therapy-based nerve repair strategies hold great promise. In the field, there is an extensive amount of evidence for better regenerative outcomes when using tissue-engineered nerve grafts for bridging severe gap injuries. Although a massive number of studies have been performed using rodents, only a limited number involving nerve injury models of large animals were reported. Nerve injury models mirroring the human nerve size and injury complexity are crucial to direct the further clinical development of advanced therapeutic interventions. Thus, there is a great need for the advancement of research using large animals, which will closely reflect human nerve repair outcomes. Within this context, this review highlights various stem cell-based nerve repair strategies involving large animal models such as pigs, rabbits, dogs, and monkeys, with an emphasis on the limitations and strengths of therapeutic strategy and outcome measurements. Finally, future directions in the field of nerve repair are discussed. Thus, the present review provides valuable knowledge, as well as the current state of information and insights into nerve repair strategies using cell therapies in large animals.

Combined Free Flaps for Optimal Orthoplastic Lower Limb Reconstruction: A Retrospective Series.

Background and Objectives: Open fracture of the lower limb can lead to substantial bone and soft tissue damage, resulting in a challenging reconstructive scenarios, especially in presence of bone or periosteal loss, with a relevant risk of non-union. This work analyzes outcomes of using a double approach for orthoplastic reconstruction, adopting the free medial condyle flap to solve the bone defects, associated to a second free flap for specific soft tissue coverage. Indications, outcomes and reconstructive rationales are discussed. Materials and Methods: A retrospective investigation was performed on patients who underwent complex two-flap microsurgical reconstruction from January 2018 to January 2022. Inclusion criteria in this study were the use of a free femoral condyle periostal/bone flap together with a second skin-only flap. Only distal third lower limb reconstructions were included in order to help equalize our findings. Out of the total number of patients, only patients with complete pre- and post-operative follow-up (minimum 6 months) data were included in the study. Results: Seven patients were included in the study, with a total of 14 free flaps. The average age was 49. Among comorbidities, four patients were smokers and none suffered from diabetes. Etiology of the defect was acute trauma in four cases and septic non-union in three cases. No major complications occurred, and all flaps healed uneventfully with complete bone union. Conclusions: Combining a bone periosteal FMC to a second skin free flap for tailored defect coverage allowed achievement of bone union in all patients, despite the lack of initial bone vascularization or chronic infection. FMC is confirmed to be a versatile flap for small-to-medium bone defects, especially considering its use as a periosteal-only flap, with minimal donor site morbidity. Choosing a second flap for coverage allows for a higher inset freedom and tailored reconstruction, finally enhancing orthoplastic success.

Cutaneous Melanoma of the Lip: A SEER Analysis of Epidemiology and Survival Outcomes With Focus on Surgery and Other Treatment Options.

BACKGROUND/AIM: Cutaneous melanoma of the lip (LM) is a rare malignancy with a low overall survival (OS). Few studies exist in the literature to aid its diagnosis and treatment. The purpose of this study was to assess the different treatment modalities by collecting cases from a single database and to provide current information on the epidemiologic characteristics of cutaneous lip melanoma. PATIENTS AND METHODS: The SEER database was searched for demographic, clinical-pathological, and therapeutic characteristics. The Kaplan-Meier model was used to analyze the overall survival (OS) of the study population, and survival curves were modelled. Univariable analysis between subgroups was carried out using the log-rank test. Surgery was further assessed with a multivariable cox regression, where the surgical procedure was adjusted for Breslow thickness. RESULTS: Patients aged 62.4 years on average, and 62.7% of them were males. A total of 386 melanomas of the cutaneous lip were identified. Mean OS was 155.1 months, median OS was 187 months, and 67.4% had localized disease. CONCLUSION: LM has a poor prognosis with a 5-year OS of 75.2%. Surgery remains the mainstay of treatment, with less invasive surgical approaches yielding a comparable overall survival to surgery with greater margins.
