RESUMEN
Background: Reduction mammoplasty can be performed in several different techniques. Understanding the complication profile and risk factors in different reduction methods can help in choosing a technique, which serves the patient best. The authors present their experience of three different reduction techniques [superomedial pedicle (SMP), superior pedicle (SP) and inferior pedicle (IP)] with an emphasis on predictors of complications. Methods: A retrospective review of a prospectively maintained database of breast reductions between 2014 and 2020 was performed. Patient's demographics [age, body mass index (BMI), comorbidities, smoking, nipple to sternal notch distance (N-SN)], operative details (pedicle, tissue resected, drains, operating surgeon) and complications according to Clavien-Dindo classification were assessed. Study variables were compared against overall complication rates for the three techniques. Results: In total, 760 patients underwent reduction mammoplasty, including 578 (76%) bilateral and 182 (24%) unilateral operations. Of patients, 477 (63%) were operated with SMP, 201 (26%) with IP and 82 (11%) with SP. An average weight of resected tissue per breast was 460 g. Overall complication rate was 38%. The rate was higher in IP group (50%) compared to SMP (36%) and SP (22%) groups (P<0.001). Complications were mainly minor and related to delayed wound healing. The rate for major complications was 4%. Multivariable analysis showed that complications were associated independently with IP [odds ratio (OR) 1.89, 95% confidence interval (CI): 1.33-2.69], age <50 years (OR 1.87, 95% CI: 1.32-2.65), bilateral operation (OR 1.67, 95% CI: 1.00-2.76) and resected tissue weight ≥650 g per breast (OR 2.02, 95% CI: 1.36-2.99). Each factor contributed 1 point in the creation of a risk-scoring system. The overall complication rate was increased as the presence of statistically significant risk factors (IP, age <50, bilateral operation and/or resected tissue ≥650 g per breast) increased (31%, 38%, 59% and 90% for number of 1, 2, 3 and 4 risk factors respectively, P<0.001). Conclusions: The rate of complication can be predicted by a risk-scoring system. In increasing variety of patients undergoing reduction mammoplasty, careful consideration of the best operation technique is important to prevent complications and costs.
RESUMEN
The purpose of the current article is to provide an overview of the functional and aesthetic unfavorable results of head and neck reconstruction, and provide suggestions on how to address these issues. Understanding the consequences of an unsuccessful reconstruction provides the foundation for proper planning and personalized approach to reconstruction of lost structures.

BACKGROUND: The aim of this study was to analyze the effects of computer-aided three-dimensional virtual planning and the use of customized cutting guides in maxillary and mandibular reconstruction with a microvascular fibula flap. METHODS: Patients (n = 17) undergoing free fibula flap (n = 18) reconstruction of the maxilla (n = 2) or mandible (n = 15) from January 2012 through March 2014 were enrolled in the study. Preoperatively, patients underwent high-resolution computed tomography of the maxillofacial and lower leg regions. Three-dimensional virtual planning of the resection and reconstruction was performed. Customized cutting guides for maxillary/mandibular resections and fibular osteotomies, and prebend plates were manufactured. Demographic data, surgical factors, and perioperative and postoperative results were evaluated. RESULTS: Sixteen patients had malignant disease and one had benign disease. Sixteen of the flaps were osteomuscular and two were osteomusculocutaneous. Mean ischemia time was 99 minutes and mean operative time was 542 minutes. The flaps fitted into the defects precisely and no bone grafts were needed. Mean length of the fibula flap was 74 mm and the mean number of segments in the flap was 2.1. CONCLUSION: Three-dimensional computer-aided preoperative virtual planning allowed for precise planning of the tumor resection and size of the fibula flap, the number and placement of the osteotomies needed, and the manufacture of customized cutting guides. Fibular shaping is easier and faster, which may decrease the ischemia time and total operative time. Exact placement of the flap in the defect may facilitate restoration of the anatomic shape and ossification.
