Dizziness Evaluation and Characterisation of Patients with Posterior Circulation Stroke in the Emergency Department; a Case Series Study.

Introduction: Dizziness is a common scenario in the Emergency Departments (EDs). Among dizziness underlying causes, the posterior circulation stroke is especially relevant due to its mobimortality and concerning misdiagnosis rates. Therefore, we conducted this study to assess dizziness evaluation and baseline characteristics of patients with PS in the ED.

Usefulness of endonasal flaps and grafts in skull base surgery. Consensus document.

Introduction: Skull base reconstruction is one of the greatest challenges extended endonasal endoscopic surgery. Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes.

Effects of Omalizumab Treatment in Patients With Recalcitrant Nasal Polyposis and Mild Asthma: A Multicenter Retrospective Study.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a clinical entity with specific features that impacts significantly on patient quality of life (QoL). CRSwNP is often associated with asthma and is difficult to control and manage despite pharmacological and/or surgical treatment. Omalizumab, a monoclonal anti-IgE antibody, has emerged as a putative therapeutic option.

Impact of Multilayer Vascularized Reconstruction after Skull Base Endoscopic Endonasal Approaches.

 The use of vascularized flap to reconstruct the skull base defects has dramatically changed the postoperative cerebrospinal fluid (CSF) leak rates allowing the expansion of endoscopic skull base procedures. At present, there is insufficient scientific evidence to permit identification of the optimal reconstruction technique after the endoscopic endonasal approach (EEA).  The main purpose of this article is to establish the risk factors for failure in the reconstruction after EEA and whether the use of a surgical reconstruction protocol can improve the surgical results.

Full endoscopic endonasal suprapetrous approach to Meckel's cave.

Background: Meckel's cave is an anatomically complex region that can be approached surgically via several routes, namely the posterolateral, lateral, anterolateral, and, due to recent advancements, anteromedial routes, with the latter being represented by the expanded endonasal approaches.

Method: We describe in detail the surgical technique of the suprapetrous endonasal approach to Meckel's cave and highlight the main anatomical key elements involved in this approach as well as the technical aspects for avoiding surgical complications.

Conclusion: The suprapetrous endonasal approach to Meckel's cave avoids the brain tissue retraction, and thereby prevents postoperative brain edema.
