Reconstruction of Complex Anterior Chest Wall Defects: The Lasagna Technique.

Background: Sternal tumors are rare, comprising only 0.94% of all bone tumors, with the majority being sarcomas. An extensive composite defect is often the result of surgical resection. Reconstruction of this anatomical area is a challenge for plastic surgeons. Reconstruction must fulfil two different tasks: restoration of soft tissues and stabilization of the chest wall. Both are well defined, and many techniques have been historically proposed. Methods: We present the case of a 66-year-old man affected by sternal metastasis of lung non-small cell carcinoma with sarcomatoid features. After wide tumor resection, a large defect was created. Results: The patient underwent a complex multilayer reconstruction that combined multiple techniques: Gore DualMesh to reconstruct the pericardial plane and protect the heart muscle, omental flap to facilitate integration of the mesh, titanium bars to recreate chest wall stability, and bilateral pectoralis muscle flaps to cover hardware. This multilayer reconstruction was named the "lasagna technique." Conclusions: Due to the rarity of primary malignancies of the sternum, it is difficult to standardize a therapeutic approach. For this reason, it is necessary to customize the surgical treatment by combining several techniques and materials. Our lasagna technique may be considered a valuable option in treating these complex reconstructive cases.

Secondary Autologous Fat Grafting for the Treatment of Chin Necrosis as a Consequence of Prone Position in COVID-19 Patients.

Due to the spread of the coronavirus disease 2019 pandemic, an increasing number of ill patients have been admitted to intensive care unit requiring mechanical ventilation. Although prone positioning is considered beneficial, long periods in this position may induce important complications, including pressure ulcers in high-risk and uncommon body areas. We report five cases of pressure ulcer necrosis of the chin in coronavirus disease 2019 patients as a consequence of mechanical ventilation in prone positioning using autologous fat grafting (AFG) as a secondary technique. A series of five patients with secondarily-healed chin necrosis treated by AFG between February and June 2020 were reviewed. All patients had been treated initially with surgical debridement followed by conservative treatment. Secondary AFG was performed to reduce patient's pain, improve chin contour-projection, and minimize cosmetic sequelae and scarring. Patient satisfaction was assessed using a five-point Likert scale (0-4). Vancouver scale was used to evaluate the chin scars clinically. The average amount of fat injected into the chin area was 8.1 ± 2.0 ml. At 6-month follow-up, all patients were mostly satisfied (average Likert-scale 3.2 ± 0.4). Based on the Vancouver scale, improvement of the chin scar from 9.5 ± 0.8 to 4.7 ± 0.8 was found. We report a positive experience with secondary AFG for correction of painful and unaesthetic scarring and contour abnormality following surgical debridement and secondary-intention healing of chin pressure ulcers.

Laparoscopically Assisted Transperineal Approach in the Management of a Giant Pelvic Lipoma.

Giant lipomas affecting the retroperitoneum and pelvis are quite rare. The surgical management of these lesions may be technically demanding and controversies exist with respect to diagnosis, competences being involved, type of surgical approach, radicality, and timing. A unique case presentation of a giant lipoma occupying the whole pelvis and the gluteal region is presented. Due to its size, many anatomical areas are involved, requiring the expertise of multiple specialists to treat. After multidisciplinary counseling, the lesion is radically resected in one stage by using a new videolaparoscopically assisted transperineal access to the pelvis. This type of surgical approach may be of interest for resecting pelvic tumors in women and men.

Necrobiosis Lipoidica Affecting the Leg: What Is the Best Treatment in a Patient with Very High Aesthetic Demand?

Necrobiosis Lipoidica (NL) is a rare necrotising disorder of the skin characterized by collagen degeneration, thickening of blood vessels, and granulomatous inflammatory process. Its main clinical features are brownish-red papules and yellowish plaques with atrophic central areas. NL affects 0.3% -1.2% of the diabetic population, mostly women (female/male ratio is 3:1). Management of NL is challenging, especially for large lesions refractory to medical therapy, thus requiring surgical excision as an alternative option. Due to the rare occurrence of this condition no treatment guidelines exist and individualized treatment mostly depends on the severity of the lesion, location and patient's expectations. A case of a 30-year-old diabetic woman with very high aesthetic expectations was succesfully treated with staged resections of a giant NL to the leg and reconstruction with dermal template and full thickness skin grafts. Grafts were taken from the groin region bilaterally and from the lower abdomen after a cosmetic mini-abdominoplasty procedure. This approach allowed for a stable and very satisfactory aesthetic result with no donor site exposed scars.

Tattooing of the nipple-areola complex: What not to do. A case series.

INTRODUCTION: Reconstruction of the nipple areola complex (NAC) is the final and easier step of breast reconstruction. However, surgeons, especially if trainees, typically have not developed tattoo skills during their training. The aim of this report is to share advice developed in our clinical practice that would minimize patient complaints and complications while performing NAC tattoos. METHODS: From January 2016 to May 2018, reconstruction of NAC was performed in 48 consecutive patients. Nipple reconstruction was performed initially using skin flaps and this was followed three to eight months later by NAC tattooing. We analyzed medical reports at 12 months follow-up where we usually record patient satisfaction (very satisfied, satisfied, dissatisfied) and every patient's complaint or complication. RESULTS: Thirty-two patients (67%) were very satisfied of NAC tattooing, twelve patients (25%) satisfied, while four patients (8%) dissatisfied. Patients complained for not having involved in choosing color, areas without sufficient pigment, extreme darkness of the tattooed NAC and artificial look. CONCLUSION: Tattooing is a simple and safe procedure, with a high satisfaction rate. Based on our experience, despite some technical aspects have to be considered, it is a procedure that can be safely performed by plastic surgical trainees.

Pectoralis Muscle Transposition in Association with the Ravitch Procedure in the Management of Severe Pectus Excavatum.

Pectus excavatum (PE) is the most common congenital chest wall deformity. PE is sometimes associated with cardiorespiratory impairment, but is often associated with psychological distress, especially for patients in their teenage years. Surgical repair of pectus deformities has been shown to improve both physical limitations and psychosocial well-being in children. The most common surgical approaches for PE treatment are the modified Ravitch technique and the minimally invasive Nuss technique. A technical modification of the Ravitch procedure, which includes bilateral mobilization and midline transposition of the pectoralis muscle flap, is presented here. METHODS: From 2010 to 2016, 12 patients were treated by a modified Ravitch procedure with bilateral mobilization and midline transposition of the pectoralis muscle flap for severe PE. Outcomes, morphological results, and complications were analyzed with respect to this new combined surgical approach. RESULTS: There was a statistically significant difference between pre- and postoperative values (P = 0.0025) of the Haller index at the 18-month follow-up, showing a significant morphological improvement for all treated patients. After surgery, no morbidity and mortality were noted. The mean hospital stay was 7 days, and all patients were discharged without major complications. CONCLUSION: This technique significantly improved patients' postoperative morphological outcomes and significantly reduced long-term complications, such as wound dehiscence, skin thinning, and hardware exposure.

Long-term efficacy and safety of polyacrylamide hydrogel injection in the treatment of human immunodeficiency virus-related facial lipoatrophy: a 5-year follow-up.

BACKGROUND: Facial lipoatrophy, a human immunodeficiency virus-related wasting of the facial soft tissues, can compromise patients' quality of life. Injection of different materials in the cheeks can improve this condition. Concern regarding potential long-term complications of nonbiodegradable fillers remains. The authors investigated the long-term efficacy and safety of polyacrylamide gel injections. METHODS: Human immunodeficiency virus-infected patients treated with polyacrylamide gel for moderate to severe facial lipoatrophy with a minimum of 5 years' follow-up were included. Aquamid (1 ml) was injected monthly into each cheek until adequate correction was obtained. Outcome measures were ultrasound measurement of cheek soft-tissues thickness, evaluation of aesthetic improvement, and self-evaluation of satisfaction and psychological consequences of treatment (visual analogue scale for the face, Assessment of Body Change and Distress questionnaire, and Beck Depression Inventory score). Adverse events were classified as acute (<1 week), early (1 week to 1 month), midterm (1 month to 1 year), or late (>1 year). RESULTS: One hundred forty-one patients completed the treatment as of June of 2005; 38 (32 men; mean age, 42 years) were available for follow-up of more than 5 years (mean, 62 months). The mean number of treatment sessions was seven over a mean period of 8 months. Significant improvement of cheek thickness and aesthetic result and highly significant satisfaction and psychological improvement were obtained. No serious adverse events occurred during the follow-up period. CONCLUSION: The long-term efficacy and safety of polyacrylamide gel injection for the treatment of human immunodeficiency virus-related facial lipoatrophy were shown over a period of 5 years. CLINICAL QUESTION/LEVEL OF EVIDENCE: : Therapeutic, IV.

High-density hyaluronic acid for the treatment of HIV-related facial lipoatrophy.

BACKGROUND: Facial lipoatrophy is a stigmatizing hallmark of HIV. The injection of facial fillers has an essential role in the treatment of this condition. The objective of our study was to verify the safety and efficacy of a new formulation of high-density hyaluronic acid for the injectable treatment of HIV-related facial lipoatrophy. METHODS: We treated with high-density hyaluronic acid injections HIV patients affected by moderate to severe facial lipoatrophy and evaluated them at last follow-up, at a minimum of 36 weeks. Physician-related outcomes included pre-and post-treatment ultrasound measurement of the soft-tissue thickness of the cheeks and qualitative assessment of aesthetic results by means of the Global Aesthetic Improvement Scale using pre- and post-treatment photos of the patients. Patient satisfaction outcomes were evaluated with the VAS-face scale and Freiburg test. RESULTS: Fifty-four patients were studied. The median number of treatment sessions was 3 and the median length of treatment was 5.5 months. The thickness of the soft tissues of the cheek increased significantly from 9.45 to 13.12 mm (p<0.0001). On the basis of the Global Aesthetic Improvement Scale, 87.5% of the patients were judged as "much improved" or "improved." Patient satisfaction at 1 year from the end of treatment was proven (VAS-face: 77.9; Freiburg questionnaire: 93.6% of patients were satisfied or very satisfied). Complications were limited to mild redness and swelling in the early postoperative period. CONCLUSION: Long-term improvement of facial contour and excellent patient satisfaction, in the absence of severe side effects, were obtained by the injection of high-density hyaluronic acid (STYLAGE® XL) in HIV patients with facial lipoatrophy.

Polyacrylamide hydrogel injection in the management of human immunodeficiency virus-related facial lipoatrophy: a 2-year clinical experience.

BACKGROUND: Facial lipoatrophy is defined as the reduction in buccal and orbital fat pads along with a more global loss of fat within the subcutaneous tissue. It is the most common and distressing sign of human immunodeficiency virus-associated lipodystrophy. Injectable polyacrylamide hydrogel (Aquamid) is a synthetic nonbiodegradable polymer consisting of a minor backbone of 2.5 percent cross-linked polyacrylamide and 97.5 percent nonpyrogenic water and is used for cosmetic facial contour correction. Favorable results with maximum aesthetic gains with the use of polyacrylamide hydrogel for reconstruction of facial lipoatrophy on the face in significantly immunocompromised individuals are being reported. These results are attributable to its use in limited volume injected at multiple sites and in multiple sittings. METHODS: Aquamid has been used for the correction of severe nasolabial folds and mid and lower facial volume loss in patients affected by human immunodeficiency virus-associated lipodystrophy. Fifty patients were enrolled and treated, with a mean follow-up of 13.1 months. Results were evaluated clinically, by standardized ultrasonography, and by psychological tests (visual analogue scale, Beck Depression Inventory, and Assessment of Body Change and Distress questionnaire) to quantify patient satisfaction. RESULTS: No significant side effects or issues such as swelling, infections, allergies, or nodule formation were noted over the follow-up period. CONCLUSION: Aquamid has provided a minimally invasive, effective, long-lasting facial contour correction that significantly improves the quality of life in human immunodeficiency virus-infected patients.

Multidisciplinary approach to the treatment of metabolic and morphologic alterations of HIV-related lipodystrophy.

BACKGROUND: Treatment for metabolic and morphologic alterations in HIV-related lipodystrophy include medical therapy, physical exercise, and surgical interventions. METHOD: We assessed the efficacy and safety of a comprehensive multidisciplinary approach for treating morphological and metabolic alterations of the lipodystrophy syndrome in consecutive patients attending the Metabolic Clinic (MC) of the University of Modena and Reggio Emilia who had at least 2 evaluations over a 48-week period. 245 patients were evaluated: 143 (62.4%) were men, 74 (36.1%) presented with lipoatrophy, 10 (4.9%) with fat accumulation, 93 (45%) with mixed forms, 24 (11.3%) had hypercholesterolemia (LDL >160 mg/dL), 87 (38%) had hypertriglyceridemia (TG >150 mg/dL), 13 (5.7%) had diabetes (glucose >126 mg/dL), and 78 (44%) had insulin resistance (HOMA-IR >4). RESULTS: At follow-up, a significant improvement was observed in both objective and subjective variables. Anthropometric improvement was observed in waist to hip ratio, waist circumference, and right and left cheek dermal thickness measurements. A nonsignificant improvement was observed in fat and lean regional mass by DEXA; CT showed improvement in visceral and subcutaneous adipose tissue. Glucose, HOMA-IR, total cholesterol, and APO B improved. Subjective variables improved in aesthetic satisfaction. CONCLUSION: We conclude that the medical and surgical interventions proposed in this multidisciplinary therapeutic approach are efficacious and safe in the management of lipodystrophy.

Comparison of three different interventions for the correction of HIV-associated facial lipoatrophy: a prospective study.

OBJECTIVE: To compare autologous fat transfer (AFT), injections of reabsorbable [polylactic acid (PLA)] and non-reabsorbable [polyacrylamide hydrogel (PAAG)] filler materials for the treatment of HIV-related facial lipoatrophy. DESIGN AND METHODS: Eligible individuals with enough residual subcutaneous fat in the abdomen or in the dorso-cervical region were offered AFT surgery. Other individuals were blindly assigned to two different surgical teams, who administered a set of PLA or PAAG injections every 4 weeks. The primary endpoint was the measurement of Bichat's fat pad region, determined by the result of dermal plus subcutaneous thickness. Secondary endpoints included body image evaluation (determined by ABCD questionnaire), facial aesthetic satisfaction (determined by Visual Analogue Scale), and aesthetic pre- and post-picture comparisons by independent reviewers. All variables were measured at baseline and at 24 weeks after the last treatment session. RESULTS: Twenty-four individuals received AFT and 35 were selectively randomized to PLA (20) or PAAG (15) infiltrations. PLA and PAAG groups received a mean of 5 and 6 injections respectively (P = NS). The mean change in dermal and subcutaneous thickness was 3.3 +/- 4.1 mm, 3.5 +/- 4.0 mm; 2.1 +/- 3.0 mm (P = 0.687), respectively. The mean change in ABCD score result was poorer in the AFT arm, but there were no other differences in other measured factors. Four serious adverse events were documented in the AFT arm only. CONCLUSIONS: All three interventional techniques were highly effective in improving the aesthetic satisfaction of the patients. Longer follow-up is necessary to determine the most durable and suitable treatment.
