Purpose/objective(s): To evaluate the role of surgical clips placement in the definition of boost treatment volume.
Materials/methods: Clinical Target Volumes (CTV) were defined as: CTV Breast, CTV Quadrant (based on physical exam and pre-surgical images), CTV Boost, defined by clip plus margin (1 cm for 2 or more clips and 2 cm for 1 clip only) plus radiological changes, CTV NT (normal tissue), defined by CTV Quadrant minus CTV Boost and CTV MISS (CTV that would be outside the treatment volume), defined by CTV Boost minus CTV Quadrant.
Results: A total of 247 patients were included.
Article Synopsis
- Some countries' large sizes and varied hospital networks limit access to proper facial trauma assessments in remote areas.
- A study evaluated 50 patients' facial trauma through both in-person and telemedicine assessments, with physicians using smartphones for remote consultations.
- Results showed high agreement between the two methods, especially in CT scan findings and treatment options, indicating the viability of telemedicine for initial trauma assessments.
Introduction: Trauma caused by traffic accidents is among the main etiologies involved in the occurrence of facial fractures throughout the world. However, the trauma mechanisms involved are different according to the location where the study was performed, due to different conditions of development, legislation, and culture. A retrospective study was done between February 2001 and July 2006, with the purpose of determining the epidemiology and the mechanisms involved in the occurrence of facial fractures among car occupants in the metropolitan area of São Paulo.
