RESUMEN
BACKGROUND: The ability to incorporate different materials in the construction of 3-D printed models has resulted in the ability to mimic a variety of anatomical structures such as cartilage, mucosa and bone. The aim of this study was to evaluate the face and content validities of a model as a training tool for endoscopic sinus surgery. METHODS: Twenty-six delegates and ten teaching faculty members were invited to complete a post-hoc questionnaire survey. The survey consisted of a 22-question 5-point Likert scale to assess the model's realism (face validity) and its effectiveness as a training tool (content validity). RESULTS: Over 80% of the delegates agreed or strongly agreed that the appearance of anatomical structures within the model was realistic and mimicked actual sinus anatomy. In addition, a similar proportion agreed or strongly agreed that the application of instruments on the composite materials of the model realistically mimicked bone. All faculty agreed that the model was useful to develop hand-eye coordination and was a useful training tool for endoscopic sinus surgery. Overall, the sinus model received high scores regarding its use for training surgeons, especially to develop camera and instrument handling skills. CONCLUSION: The results of this study suggest that otolaryngology doctors in their early or intermediate stage of training would benefit most from a clinical-based modular programme. The model requires further development in areas such as the realism of mucosa, incorporation of sinonasal pathology and having more complex anatomy to be useful for the training of more advanced surgeons.

The first Rhinology Future Debates was held in Brussels in December 2016, organized by EUFOREA (European Forum for Research and Education in Allergy and Airways diseases). The purpose of these debates is to bring novel developments in the field of Rhinology to the attention of the medical, paramedical and patient community, in a highly credible and balanced context. For the first time in Rhinology, a peer to peer scientific exchange with key experts in the field of rhinology and key medical colleagues from leading industries let to a brainstorming and discussion event on a number of hot issues in Rhinology. Novel developments are presented by key experts from industry and/or key thought leaders in Rhinology, and then followed by a lively debate on the potential positioning of new developments in care pathways, the strengths and weaknesses of the novel development(s), and comparisons with existing and/or competing products, devices, and/or molecules. As all debates are recorded and distributed on-line with limited editing (www.rhinology-future.com), EUFOREA aims at maximizing the education of the target groups on novel developments, allowing a critical appraisal of the future and a more rapid implementation of promising novel tools, techniques and/or molecules in clinical practise in Europe. The next Rhinology Future debate will be held in Brussels in December 2017.

Three cases of medially displaced extrapleural fat are presented. In these cases displacement is secondary to tumor, thoracic wall edema, and hematoma. When significantly displaced, and especially when distorted, the extrapleural fat may present a confusing CT picture. The recognition of this finding may aid in establishing differential diagnosis and staging.

Transjugular catheterization of the portal vein can be used to form a portosystemic shunt. Conventionally, the passage of a needle from the hepatic vein into the portal vein is performed with fluoroscopic monitoring only. Several methods to target the portal vein have been previously reported, including transhepatic venous catheterization, indirect portography (arterial catheterization), or skin marking based on ultrasound (US) mapping of portal landmarks. The authors used realtime US guidance to percutaneously place a small marking wire in the parenchyma next to the portal bifurcation. A 0.018-inch-diameter, 5-mm-long platinum wire is delivered through a 22-gauge echo-tipped needle placed adjacent to the right portal vein. This marking wire enabled rapid entry into the portal vein, helped avoid extrahepatic puncture, and was useful during stent deployment and positioning.
