Insights on the Choice and Preparation of the Donor Nerve in Corneal Neurotization for Neurotrophic Keratopathy: A Narrative Review.

The article introduces neurotrophic keratopathy (NK), a condition resulting from corneal denervation due to various causes of trigeminal nerve dysfunctions. Surgical techniques for corneal neurotization (CN) have evolved, aiming to restore corneal sensitivity. Initially proposed in 1972, modern approaches offer less invasive options. CN can be performed through a direct approach (DCN) directly suturing a sensitive nerve to the affected cornea or indirectly (ICN) through a nerve auto/allograft. Surgical success relies on meticulous donor nerve selection and preparation, often involving multidisciplinary teams. A PubMed research and review of the relevant literature was conducted regarding the surgical approach, emphasizing surgical techniques and the choice of the donor nerve. The latter considers factors like sensory integrity and proximity to the cornea. The most used are the contralateral or ipsilateral supratrochlear (STN), and the supraorbital (SON) and great auricular (GAN) nerves. Regarding the choice of grafts, the most used in the literature are the sural (SN), the lateral antebrachial cutaneous nerve (LABCN), and the GAN nerves. Another promising option is represented by allografts (acellularized nerves from cadavers). The significance of sensory recovery and factors influencing surgical outcomes, including nerve caliber matching and axonal regeneration, are discussed. Future directions emphasize less invasive techniques and the potential of acellular nerve allografts. In conclusion, CN represents a promising avenue in the treatment of NK, offering tailored approaches based on patient history and surgical expertise, with new emerging techniques warranting further exploration through basic science refinements and clinical trials.

Multidisciplinary Management of Cutaneous Squamous Cell Carcinoma of the Scalp: An Algorithm for Reconstruction and Treatment.

Background: Scalp-associated cutaneous squamous cell carcinoma (cSCC) presents formidable treatment challenges, especially when it leads to full-thickness defects involving bone. Aggressive or recurring cases often demand a multidisciplinary approach. Leveraging our surgical experience and a literature review, we introduce a therapeutic algorithm to guide the selection of reconstruction methods, particularly for locally advanced lesions, furthermore showing the synergy between surgery and other therapies for comprehensive, multidisciplinary disease management. Methods: Our algorithm stems from a retrospective analysis of 202 patients undergoing scalp cSCC resection and reconstruction over a 7-year period, encompassing 243 malignancies. After rigorous risk assessment and documentation of surgical procedures, reconstruction methods were therefore related to malignancy extent, depth, and individual clinical status. Results: The documented reconstructions included 76 primary closures, 115 skin grafts, 7 dermal substitute reconstructions, 33 local flaps, 1 locoregional flap, and 1 microsurgical free flap. Patients unsuitable for surgery received radiotherapy or immunotherapy after histological confirmation. Precise analysis of tumor characteristics in terms of infiltration extent and depth guided the selection of appropriate reconstruction and treatment strategies Combining these insights with an extensive literature review enabled us to formulate our algorithm for managing scalp cSCCs. Conclusions: Effectively addressing scalp cSCC, especially in locally advanced or recurrent cases, demands a systematic approach integrating surgery, radiotherapy, and immunotherapy. Our multidisciplinary team's decision-making algorithm improved patient outcomes by offering a broader spectrum of therapeutic options that can synergistically achieve optimal results.

Technical Refinements and Outcomes Assessment in Prepectoral Pocket Conversion After Postmastectomy Radiotherapy.

BACKGROUND: Several studies show how submuscular breast reconstruction is linked to animation deformity, shoulder dysfunction, and increased postoperative chest pain, when compared to prepectoral breast reconstruction. In solving all these life-impairing side effects, prepectoral implant pocket conversion has shown encouraging results. OBJECTIVES: The aim of this study was to propose a refinement of the prepectoral implant pocket conversion applied to previously irradiated patients. METHODS: We conducted a retrospective study on 42 patients who underwent previous nipple- or skin-sparing mastectomy and immediate submuscular reconstruction, followed by radiotherapy. We performed fat grafting sessions as regenerative pretreatment. Six months after the last fat graft, we performed the conversion, with prepectoral placement of micropolyurethane foam-coated implants. We investigated the preconversion and postconversion differences in upper limb range of motion, Upper Extremity Functional Index, and patient satisfaction with the breast and physical well-being of the chest. RESULTS: We reported a resolution of animation deformity in 100% of cases. The range of motion and the Upper Extremity Functional Index scores were statistically improved after prepectoral implant pocket conversion. BREAST-Q scores for satisfaction with the breast and physical well-being of the chest were also improved. CONCLUSIONS: The refined prepectoral implant pocket conversion is a reliable technique for solving animation deformity and improving quality of life in patients previously treated with submuscular reconstruction and radiotherapy.

Objective Non-Invasive Bio-Parametric Evaluation of Regenerated Skin: A Comparison of Two Acellular Dermal Substitutes.

Several dermal substitutes are available on the market, but there is no precise indication that helps surgeons choose the proper one. Few studies have tried to compare different xenogeneic bioengineered products, but no objective bio-parametric comparison has been made yet. Fifteen patients who underwent skin reconstruction with Integra® or Pelnac® were retrospectively evaluated. After at least 12 months of follow-up, an objective and quantitative assessment of several skin biophysical properties, such as color, texture, elasticity, hydration, glossiness and trans-epidermal water loss, were measured with non-invasive skin measurement devices. The grafted skin showed a reduction of the superficial hydration level and a tendency to lower values of trans-epidermal water loss with both dermal substitutes. Melanic and hemoglobin pigmentation were higher in comparison to the donor site in both groups, while a melanic pigmentation increase versus the surrounding skin was seen just with Integra®. Finally, the skin was found to be more elastic when reconstructed with Integra®. The skin barrier appeared to be intact in both groups. Hence, these substitutes are valuable means of skin regeneration. Integra® seems to be more advantageous for reconstructing areas that need more skin flexibility.

Salvage Strategies for Local Recurrences of Squamous Cell Carcinoma of the Nasal Vestibule: A Single-Center Experience of 22 Years.

Squamous cell carcinomas of the nasal vestibule are an extremely rare neoplastic disease. Although brachytherapy is gaining popularity for primary treatment, surgery remains the best option in case of recurrences. The aim of this paper is to outline our treatment experience of local recurrence of SCCNVs over the past 22 years. We retrospectively reviewed the clinical data of the patients who underwent surgical treatment for local recurrence of SCCNV: data regarding age, sex, primary tumor treatment, recurrence location and time of appearance, surgical resection, type of reconstruction, postoperative complication, surgical revision, and re-recurrence rate were analyzed. Twenty patients were included in the study. The median period for recurrence appearance was 17 months, and the prevalent location of recurrence was the nasal alae. Prevalent reconstructive procedures were the nasolabial flap and paramedian forehead flap. No postoperative complications were observed, and one case of re-recurrence was detected at 12-months of follow-up. Based on our experience, salvage surgical procedures for SCCNV recurrences must be individualized and carefully planned, taking into account the peculiar pattern of tumor spread and the presence of scar and heavily radiotherapy damaged tissue from previous treatment; delayed reconstruction should be considered for all the cases with skeletal involvement.

Prevention of Breast Cancer-Related Lymphedema: An Up-to-Date Systematic Review of Different Surgical Approaches.

Breast cancer-related lymphedema (BCRL) affects approximately 20% of women after breast cancer therapy. Advances in treatment have increased the life expectancy; thus, the prevalence of BCRL will continue to rise with the number of cancer survivors, hence the need to develop strategies to prevent this condition. We provide a systematic review of the literature on the primary prevention of BCRL by prophylactic lymphatic surgery (PLS). Between June and August 2022, we conducted a search of PubMed, Google Scholar and Cochrane. In the end, a total of eighteen papers were selected. The eleven studies without a control group reported only 15 of 342 patients who developed lymphedema at least six months after PLS (4.59%). The seven studies with a control group included 569 patients, 328 cases and 241 controls. Among the cases, 36 (10%) developed lymphedema. In contrast, the incidence of lymphedema in the controls was 40% (98 of 241 patients). The formulation of definite recommendations in favor of PLS is hindered by low-quality studies. There is no consensus on which technique should be preferred, nor on whether adjuvant radiotherapy might affect the efficacy of PLS. Randomized controlled trials are mandatory to conceive evidence-based recommendations.

Use of Radiofrequency-Assisted Liposuction (BodyTite) for Upper Arms Lifting.

BACKGROUND: Body contouring surgery is increasingly requested by patients, both for aesthetic and post-bariatric purposes. There has also been a rapid increase in demand for noninvasive aesthetic treatments. While brachioplasty is burdened by numerous complications and unsatisfactory scars, and conventional liposuction is unsuitable for all patients, nonsurgical arm remodeling performed with radiofrequency-assisted liposuction (RFAL) allows to effectively treat most of patients, regardless of the amount of fat and ptosis of the skin and avoiding surgical excision. METHODS: A prospective study was conducted on 120 consecutive patients who presented to the author's private clinic and required upper arm remodeling surgery for aesthetic purposes or after weight loss. Patients were classified according to the modified classification of El Khatib and Teimourian. Pre- and posttreatment upper arm circumferences were taken after 6 months of follow-up to assess the degree of skin retraction obtained by treating the arm with RFAL. A satisfaction questionnaire regarding the appearance of the arms (Body-Q upper arm satisfaction) was administered to all patients before surgery and after 6 months of follow-up. RESULTS: All patients were effectively treated with RFAL, and no cases required conversion to brachioplasty. The average reduction in arm circumference was 3.75 cm at 6 months follow-up, and patients' satisfaction increased from 35 to 87% posttreatment. CONCLUSIONS: Radio frequency is a valid tool to treat most patients with upper limbs skin laxity, with significant aesthetic results and a high degree of patient satisfaction, regardless of the degree of skin ptosis and lipodystrophy of the arm.

Outcomes of Intramuscular Gluteal Augmentation With Implants Using Tumescent Local Anesthesia.

BACKGROUND: Tumescent local anesthesia (TLA) describes the practice of injecting a very dilute solution of local anesthetic combined with epinephrine and sodium bicarbonate into the tissue until it becomes firm and tense to obtain local anesthesia and vasoconstriction. The use of TLA in augmentation intramuscular gluteoplasty has never been described for implants positioning. Advantages of the TLA technique include a reduction in blood loss through epinephrine-induced vasoconstriction and hydrostatic compression from the tumescent effect. We describe TLA technique for primary intramuscular gluteal augmentation, reporting our experience during the last 5 years. METHODS: From 2017 to 2021, 20 patients underwent bilateral primary gluteal augmentation under TLA and conscious sedation. The tumescent solution was prepared with 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) in 1000 mL of 0.9% saline solution. The solution was infiltrated with a cannula inside the gluteus maximus muscle intra-operatively. RESULTS: The mean age of the patients was 39, 15 years. The average amount of tumescent solution infiltrated was 240 mL per gluteus. Operating time was 1 h and 40 min, and recovery room time averaged 240 min. Major surgery-related complications were found in 15% of patients (2 hematomas and 1 seroma) and minor complications were described in a total of 8 patients (4 wound dehiscence and 1 dystrophic scar formation). No signs of adrenaline nor lidocaine toxicity were reported and conversion to general anesthesia was never required. CONCLUSIONS: The tumescent local anesthesia technique represents a safe and efficacious technique for performing gluteal augmentation surgery with an intramuscular implant positioning. The advantages of this technique are safety, reasonable pain control during and after surgery and a low incidence of postoperative side effects due to general anesthesia avoidance.

Heel reconstruction with ALT free flap in a 4-year-old patient after a severe lawnmower injury. A case report.

Lawnmowers represent a danger in pediatric population. Frequently, traumas involve limbs. Among the different reconstructive techniques, a free flap is often needed. We discuss the first case of heel reconstruction with an anterolateral thigh flap in a 4-years-old patient after a lawnmower's trauma.

Hybrid breast augmentation: our surgical approach and formula for preoperative assessment of fat graft volume.

Background: Autogenous fat grafting (AFG) is a well-known procedure utilized in addition to breast augmentation (BA) to improve breast appearance. Plastic surgeons usually estimate the ideal AFG volume relying on their personal experience based on similar previous cases: inaccurate predictions could result in incorrect evaluation of donor sites and even needless fat transfer. The purpose of this paper is to describe and prove the validity of our surgical technique and provide a simple and easy-to-use mathematical formula to assess the adequate proportion, between the volume of the implants and of the AFG, in order to obtain a natural shape and a proper volume in BA. Methods: One hundred and twenty-two patients (244 breasts) were subjected to primary/secondary hybrid BA (HBA). A formula was utilized to assess the volume of fat graft. Data about their age, body mass index (BMI), incision and implants were collected. Follow-up for analysis was fixed at less than 15 days, 1, 3, 6 and 12 months for analysis. Preoperative photographs were compared with postoperative at 12 months. Pre and postoperative Breast-Q© were administered to every patient. A statistical analysis was performed comparing Breast-Q© preoperative means with postoperative ones through t-student test. We globally defined the patients as follows: "very dissatisfied" if total score 0-25; "somewhat dissatisfied", score 26-50; "somewhat satisfied", score 51-75; "very satisfied", score 76-100. Results: All patients received Ergonomix-style Motiva Smooth/SilkSurface with low/high projection (range, 120-225 mL, mean 170 mL) and an average AFG volume of 600 mL (range, 480-720 mL). Breast-Q© analysis showed a statistically significant difference between preoperative and postoperative modules; 122 (100%) patients were "very satisfied". Thirteen cases of complications presented in 12 patients (10.65%): 5 hypertrophic scarring (4.09%), 3 wound dehiscence (2.46%), 3 hematomas (2.46%), 1 seroma (0.82%), 1 fat necrosis (0.82%). Conclusions: Our surgical technique proves low complication rate and short recovery times. Our mathematical formula to calculate the AFG seems to be both predictive and a precise guide for surgical decision-making in planning the treatment of patients candidated for HBA. In fact, the analysis of Breast-Q© questionnaires shows a high grade of satisfaction among patients. Further investigations should be performed in order to study a wider population and different type of implants.

Reconstruction of a fistula in the anterior soft triangle of the nose after basal cells carcinoma excision: A case report.

INTRODUCTION AND IMPORTANCE: Basal cell carcinomas represent the most frequent skin cancer and the nose is the most common site of presentation. This has an impact on both aesthetics and function of the nose and consequences in patients' psyche. CASE PRESENTATION: In our paper, the first case in literature of a cutaneous fistula in the nasal soft triangle, after a basal cell carcinoma excision, and its reconstruction, is reported. CLINICAL DISCUSSION: One of the areas of weakness of the nose is the anterior soft triangle; here, any minimal alteration of the anatomy can potentially lead to severe impairment. CONCLUSION: When the nasal soft triangle is damaged, its restoration is crucial. Our technique showed both functional and aesthetic good result.

Iatrogenic subcutaneous emphysema in aesthetic breast augmentation Medicolegal aspects.

The aim of the present study was to investigate clinical results and medico-legal aspects related to the surgical procedure of mini breast augmentation. In the present case, a 28-year-old young woman with bilateral mammary hypoplasia underwent surgery, under local anesthesia, with the placement of 150 cc breast implants in the sub-glandular plane. We report a case of dramatic isolated subcutaneous emphysema without pneumothorax and pneumomediastinum to be related in terms of a causal link to the surgical procedure which the patient underwent. The plastic surgeon proceeded to replace a breast implant that presumably, represented the vehicle of transmission of the suspected pathogen responsible for the infection, to become a causal role for the infectious manifestation. This case report is an emblematic example of the need for a careful and correct surgical procedure, in order to avoid serious consequences as in the case in question, burdened by the occurrence of unsafe conditions for the patient. Compliance with the guidelines and the technical datasheet of breast implants is essential in order to avoid the concrete hypothesis of professional liability. KEY WORDS: Aesthetic breast augmentation, Breast implant, Iatrogenic subcutaneous emphysema.

Complications after breast augmentation with hyaluronic acid: a case report.

Breast augmentation is a very requested procedure in aesthetic surgery. Over time, various techniques of breast augmentation have been described, both through the use of alloplastic materials and autologous tissues: implants, fat grafting, flap surgery, and injectable fillers. According to the international current trend to perform minimally invasive procedure, injectable fillers have progressively increased their uses and notoriety in aesthetic medicine. Among the various available products, hyaluronic acid is likely to be the most popular synthetic filler all over the world. Nowadays many brands are on the market and this paper focuses on Macrolane which is a NASHA-based (stabilized hyaluronic acid of non-animal origin) filler. However, although highly biocompatible, as any material, foreign to our body, also hyaluronic acid fillers undergo a process of degradation and disposal. In our work, we report the first case in literature of migration of Macrolane in an axillary lymph node in a 45-year-old woman three years after injection for breast augmentation and its related management. The aim of the paper is to discuss and underline further complications and their treatment besides the ones already described in literature in order to provide a deeper knowledge concerning the use and the side effects of injectable fillers in aesthetic medicine.
