Comparison of Outcomes in Immediate Implant-Based Breast Reconstruction: Acellular Dermal Matrix versus Inferior Dermal Flap.

Background Implant-based breast reconstruction has evolved tremendously in the last decades, mainly due to the development of new products and techniques that make the procedure safer and more reliable. The purpose of this study was to compare the outcomes in immediate one-stage breast reconstruction between acellular dermal matrix (ADM) and inferior dermal flap (IDF). Methods We conducted a retrospective comparative study of patients submitted to immediate breast reconstructions with an anatomical implant and ADM or IDF in a single center between 2016 and 2018. Outcomes evaluated included major complications, early complications, reinterventions, readmissions, and reconstruction failure. Simple descriptive statistics and univariate analysis were performed. Results A total of 118 breast reconstructions (85 patients) were included in the analysis. Patients in the IDF group had a higher body mass index (median = 27.0) than patients in the ADM group (median = 24). There were no statistically significant differences among both groups regarding immediate major complication, early complications, readmissions, and reinterventions. Conclusion There are no significant differences in complications between the ADM and IDF approach to immediate implant breast reconstruction. In patients with higher body mass index and large, ptotic breasts, we recommend an immediate implant reconstruction with IDF.

Impact of Body Mass Index, Age and Tobacco Use on the Outcomes of Immediate Breast Reconstruction with Implants and Acellular Dermal Matrix.

Background This study aimed to analyze the effect of body mass index (BMI), age, and tobacco use on alloplastic breast reconstruction. Methods We conducted a retrospective study of patients who submitted to immediate breast reconstructions with an anatomical implant and acellular dermal matrix in a single center between 2016 and 2018. Outcomes evaluated included immediate complications, early complications, reinterventions, readmissions, and reconstruction failure. Patients were divided into two groups concerning each potential risk factor (BMI < or ≥25; age < or ≥ 50 years; and smokers vs nonsmokers). Simple descriptive statistics and univariate analysis were performed. Results A total of 101 breast reconstructions (73 patients) were included in the analysis. The mean BMI was 24, and the mean age was 44.5 years old. Smokers accounted for 14 breast reconstructions (13.9%). The rate of early infections, mastectomy flap necrosis, and implant removal was significantly higher in overweight patients. The total volume of breast drainage was higher in the age ≥ 50 years group. Smoking did not alter the outcomes. Conclusions A BMI ≥ 25 is a risk factor for early infections and reconstructive failure. Age ≥ 50 years is associated with a higher volume of breast drainage but does not seem to impact the success of the reconstruction. Smoking does not appear to affect the outcomes significantly in this type of reconstruction. Surgeons should consider delaying the reconstruction or using autologous tissue when patients are overweight.

Giant chondrosarcoma of the chest wall: a rare surgical challenge.

The chest wall chondrosarcoma (CWC) is a rare slowly growing primary tumor of the chest wall with an incidence of <0.5 per million person-years. We present the case of a giant CWC that caused a mass effect on the mediastinum, heart, and lung. Large tumors with thoracic structures compression may be life threatening, and its resection and subsequent chest wall reconstruction represent a significant multidisciplinary surgical challenge. In this case, despite the large tumor dimensions, the preoperative planning-sparing key reconstructive options without compromising the tumor resection-allowed a complete en bloc tumor excision of a grade III chondrosarcoma with negative histologic margins. Successful reconstruction of the large full-thickness chest wall defect, with a latissimus dorsi muscle flap and methyl methacrylate incorporated into a polypropylene mesh in a sandwich fashion, was accomplished. Patient recovery was uneventful with good functional and aesthetic outcomes, and no evidence of recurrence at 1.5 years follow-up. This case report illustrates the main clinical, radiological, and histologic features of a CWC while discussing the surgical goals and highlighting the principles for chest wall reconstruction following extensive resection of a large and rare entity.

Bilateral Lower Limb Salvage after Fourth-degree Burns: Subscapular Axis Free and Chimeric Flaps Effectiveness in Complex Reconstruction.

Microsurgery is usually required for reconstruction of complex lower limb defects, preserving otherwise unsalvageable injuries. Fourth-degree burns are severe traumatic injuries. A case of bilateral lower limb salvage through a resourceful use of subscapular axis free and chimeric flaps for acute burn reconstruction of extensive lower leg injuries is reported. A 48-year-old man sustained a 40% surface area flame burn, circumferential and full-thickness at the lower limbs. Debridement of fourth-degree burns of the anterior lower legs resulted in bone exposure of the left and right tibias, right medial malleolus, and Achilles tendon. A latissimus dorsi (LD) flap plus a chimeric subscapular axis free flap with 3 components (LD, serratus anterior (SA), and parascapular) were designed for reconstruction. LD insetting for left tibia coverage with anastomoses to anterior tibial vessels was performed. Right side flap insetting provided tibia coverage with LD; medial malleolus with SA; and Achilles tendon with parascapular flap. An anatomical variation required anastomoses to proximal (chimeric LD + SA) and distal (parascapular) ends of posterior tibial vessels because of an independent origin of the pedicles. At 10-months follow-up after intensive rehabilitation, the patient showed proper functional outcomes at daily-life and work activities with autonomous walking using a single crutch. This case highlights the importance of microsurgery and chimeric flaps for limb salvage in extreme situations. The authors review and discuss the surgical options, emphasizing specific considerations of microsurgical reconstruction in burn patients.

Abdominoplasty and Patient Safety: The Impact of Body Mass Index and Bariatric Surgery on Complications Profile.

BACKGROUND: Abdominoplasty is a frequent aesthetic surgical procedure. Despite its popularity, patient safety requires further attention because of an important risk of complications. Obesity and bariatric surgery are potential risk factors. This study evaluated the impact of body mass index (BMI) and bariatric surgery on complications profile. METHODS: A retrospective review of patients undergoing abdominoplasty over a 5-year period was conducted. Patient demographics, comorbidities, BMI, bariatric surgery, complications (minor and major) and drainage outcomes were evaluated. Univariate and multivariate logistic regression analyses were performed for risk assessment. RESULTS: The 191 study patients showed an overall complication rate of 32.5%, comprising minor (27.7%) and major complications (7.9%). Seroma was the most common complication (20.9%). Mean BMI was 27.1 kg/m2. Obesity was present in 14.1%, and bariatric surgery in 53.4%. Obese patients had significant higher rates of overall complications (74.1%, p < 0.001), minor complications (66.7%, p < 0.001), seroma (51.9%, p < 0.001) and drainage outputs (p < 0.001). Bariatric patients showed an increased time (p = 0.003) and volume of drainage (p < 0.001), without significant differences in complications. Obesity and preoperative BMI were the only independent risk factors for overall complications (OR 8.3; and OR 1.3; p < 0.001), minor complications (OR 7.4; and OR 1.3; p < 0.001) and seroma (OR 4.5; and OR 1.2; p = 0.002). Diabetes was an independent risk for major complications (OR 4.6; p = 0.047). CONCLUSION: Obesity has negatively impacted the profile and risk of complications, whereas bariatric surgery independently did not. Our study provides an accurate understanding of abdominoplasty complications, allowing better risk stratification, candidate selection refinement, morbidity reduction, fair patient counseling and overall improvement in patient safety.

Evidence-based Nasal Analysis for Rhinoplasty: The 10-7-5 Method.

Rhinoplasty is one of the top 5 aesthetic surgical procedures performed in plastic surgery. A methodical evaluation based on solid and up-to-date scientific evidence in different key areas of nasal and facial analysis is presented, the 10-7-5 method. This represents the most important preoperative step for a successful rhinoplasty. The 10-7-5 method for nasal analysis is a useful instrument that provides the rhinoplasty surgeon a deep comprehension of nasal anatomy. Understanding the nasal structures' main relationships and consequences of each surgical maneuver on nasal framework assists on establishing the appropriate surgical goals for each patient, both in primary and secondary rhinoplasty cases. This systematic analysis of patient's frontal, lateral, and basal nasal views provides a background to identify changes to ideal aesthetic proportions and how to surgically restore them while maintaining gender and ethnic congruency.
