(1) Background: A decrease in operative time can not only improve patient outcomes through a reduction in the risk of developing complications but can also result in cost savings. The aim of this study is to determine whether there an intraoperative time gain can be achieved by using the preoperative virtual planning of mandibular reconstruction using a free fibula flap compared with freehand plate bending and osteotomies. (2) Methods: A retrospective comparative study was carried out in the Oral and Maxillofacial Department of La Paz University Hospital, Madrid, Spain. The study compared 18 patients in the CAD/CAM group with 19 patients in the conventional freehand group. A comparison was made between the total surgical time, the comorbidities, and the hospital stay. The resource consumption was estimated using a cost analysis. (3) Results: Although CAD/CAM was a statistically more expensive procedure in the perioperative phase, no significant differences were observed in total health care costs between the two groups. There was a non-significant trend towards an increase in complications with conventional reconstruction plates compared to patient-specific plates (PSI). (4) Conclusions: CAD/CAM technology and a 3D printed cutting guide offer a significantly shorter surgical time, which is associated with a reduction in hospital days, PACU days, and complications. The cost of CAD/CAM technology is comparable to that of the conventional freehand technique.

(1) Background: Surgical outcomes in free flap reconstruction of head and neck defects in cancer patients have improved steadily in recent years; however, correct anaesthesia management is also important. The aim of this study has been to show whether goal directed therapy can improve flap viability and morbidity and mortality in surgical patients. (2) Methods: we performed an observational case control study to analyse the impact of introducing a semi invasive device (Flo Trac^®) during anaesthesia management to optimize fluid management. Patients were divided into two groups: one received goal directed therapy (GDT group) and the other conventional fluid management (CFM group). Our objective was to compare surgical outcomes, complications, fluid management, and length of stay between groups. (3) Results: We recruited 140 patients. There were no differences between groups in terms of demographic data. Statistically significant differences were observed in colloid infusion (GDT 53.1% vs. CFM 74.1%, p = 0.023) and also in intraoperative and postoperative infusion of crystalloids (CFM 5.72 (4.2, 6.98) vs. GDT 3.04 (2.29, 4.11), p < 0.001), which reached statistical significance. Vasopressor infusion in the operating room (CFM 25.5% vs. GDT 74.5%, p < 0.001) and during the first postoperative 24h (CFM 40.6% vs. GDT 75%, p > 0.001) also differed. Differences were also found in length of stay in the intensive care unit (hours: CFM 58.5 (40, 110) vs. GDT 40.5 (36, 64.5), p = 0.005) and in the hospital (days: CFM 15.5 (12, 26) vs. GDT 12 (10, 19), p = 0.009). We found differences in free flap necrosis rate (CMF 37.1% vs. GDT 13.6%, p = 0.003). One-year survival did not differ between groups (CFM 95.6% vs. GDT 86.8%, p = 0.08). (4) Conclusions: Goal directed therapy in oncological head and neck surgery improves outcomes in free flap reconstruction and also reduces length of stay in the hospital and intensive care unit, with their corresponding costs. It also appears to reduce morbidity, although these differences were not significant. Our results have shown that optimizing intraoperative fluid therapy improves postoperative morbidity and mortality.

El objetivo de esta investigación fue la identificación de las prácticas ambientales en las pymes de la Ciudad de México, así como la relación de estas prácticas con las características de las empresas y los empresarios. Se recolectaron los datos por medio de una encuesta estructurada y descriptiva, sobre una muestra de 300 empresas voluntarias. Los principales hallazgos permitieron determinar que las prácticas de gestión ambiental de mayor uso son el diseño de planta y la eficiencia en el uso de insumos y materias primas se confirma así la existencia de relación entre el sector industrial y el diseño de sus plantas de producción, así como el consumo de energía, agua y materias primas, y la implementación de políticas sobre el manejo de residuos, sus certificaciones y/o capacitaciones. También, se confirma la existencia de una relación importante entre el nivel educativo de los empresarios y la presencia de certificaciones dentro de la empresa.

Background: Orthognathic surgery is commonly performed to correct malocclusion and facial asymmetry, typically in young and healthy patients. However, it's crucial to recognize that facial deformities can also be features of various syndromes, complicating the surgical and anesthetic management. Material and Methods: This review examines the key factors influencing anaesthesia management in orthognathic surgery patients. The perioperative care process was analyzed, focusing on the surgical procedure, airway management, and anaesthesia techniques. Additional factors considered include bleeding control, postoperative nausea and vomiting (PONV), antibiotic prophylaxis, analgesia, and deep venous thrombosis (DVT) prevention. Results: The review highlighted the critical role of comprehensive anaesthesia management in determining the outcomes of orthognathic surgery. Proper airway management, effective bleeding control, and the prevention of PONV and DVT were identified as significant factors in optimizing patient recovery. The use of protocols and a multidisciplinary approach were emphasized as essential in minimizing complications and improving postoperative outcomes. Conclusions: Comprehensive and carefully planned anesthesia management is vital for the success of orthognathic surgery. Employing a multidisciplinary approach and adhering to established protocols can enhance patient outcomes and expedite recovery, especially in cases involving complex syndromic patients.
