Dynamic Trends in Surgical Oromaxillofacial Trauma Epidemiology: A Comparative Study of Pre-COVID-19 and COVID-19 Periods in Tertiary Referral Hospitals in Madrid.

: The COVID-19 pandemic has induced profound societal and healthcare transformations globally. : This multicenter retrospective study aimed to assess potential shifts in the epidemiology and management of oromaxillofacial trauma requiring surgical intervention over a 1-year period encompassing the onset of the COVID-19 pandemic, in comparison to the preceding year. The parameters investigated included age, sex, injury mechanisms, fractured bones, and treatment modalities.

Embryonal Rhabdomyosarcoma of the Tongue in Adults.

(1) Background: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the first two decades of life. One third of cases appear in the head and neck, with 60% of these being embryonal type. RMS is extremely rare in adults, comprising only 1% of adult malignancies, and of those, only 3.

Cervical Lymphadenopathies as Unusual Presentations of Erdheim-Chester Disease: The Need for Knowledge for Diagnosis and Treatment.

The appearance of cervical adenopathies can occur in many pathologies in a non-specific manner; Erdheim-Chester disease (ECD) is characterized by xanthogranulomatous and xanthomatous infiltration of different tissues with numerous foamy histiocytes. Bone lesions are frequent and radiological features are pathognomonic for diagnosis, but lymph node involvement is exceptional and is not a form of presentation reported in the literature. Recurrent BRAFV600E mutation and others have been discovered in recent years.

Mandibular Reconstruction With Fibula Flap and Dental Implants Through Virtual Surgical Planning and Three Different Techniques: Double-Barrel Flap, Implant Dynamic Navigation and CAD/CAM Mesh With Iliac Crest Graft.

Introduction: Vertical discrepancy between the fibula flap and the native mandible results in difficult prosthetic rehabilitation. The aim of this study was to evaluate the outcomes of 3D reconstruction of the mandible in oncologic patients using three different techniques through virtual surgical planning (VSP), cutting guides, customized titanium mesh and plates with CAD/CAM technology, STL models and intraoperative dynamic navigation for implant placement. Material and methods.

Intraosseous Venous Malformation of the Zygomatic Bone: Virtual Surgical Planning and Reconstruction With Customized CAD-CAM Titanium Implant.

Zygomatic intraosseous vascular anomalies are uncommon. Most cases have been reported without a precise diagnosis. The prevalence is 3:1 women during the fourth decade of life.

Consensus document on the use of antibiotic prophylaxis in dental surgery and procedures.

The goal of antibiotic prophylaxis in Odontology is to prevent the onset of infections through the entranceway provided by the therapeutic action, therefore it is indicated providing there is a considerable risk of infection, either because of the characteristics of the operation itself or the patient s local or general condition. Nonetheless, clinical trials with antibiotics in dental pathologies have had scant regard for the required methodological criteria and, in addition, are not sufficiently numerous. This text presents the results of an expert conference comprising the Presidents of the most representative Scientific Societies in Spain who have analyzed the existing literature and have drawn on their valuable professional experience.
