Adherence in Evidence-Based Neurotrauma Guidelines: A Worldwide Survey.

Background: Traumatic brain injury (TBI) management guidelines vary across regions and there is limited research on real-world adherence to these guidelines. We conducted a global survey to assess the adherence of neurosurgeons to TBI guidelines and evidence-based medicine (EBM).

Method: A 24-item survey was created using Google Forms, covering demographic information, neurotrauma training, basic knowledge of EBM, surgical and in-hospital management.

Reversible Endoscopic Medial Maxillectomy: Endonasal Approach to Diseases of the Maxillary Sinus.

 The endoscopic access has reduced the morbidity associated with external approaches in diseases of the maxillary sinus. A reversible endoscopic medial maxillectomy (REMM) is presented as an alternative for treatment of benign maxillary diseases.  To describe the REMM technique and report four cases of patients with benign maxillary sinus conditions treated through this approach.

Lengthening the nasoseptal flap pedicle with extended dissection into the pterygopalatine fossa.

Objectives/hypothesis: Releasing the nasoseptal flap (NSF) pedicle from the sphenopalatine artery (SPA) foramen may considerably improve flap reach and surface area. Our objectives were quantify increases in pedicle length and NSF reach through extended pedicle dissection into the pterygopalatine fossa (PPF) through cadaveric dissections and present clinical applications.

Study Design: Anatomical study and retrospective clinical cohort study.

Unilateral Endoscopic Endonasal Surgery for Resection of an Olfactory Schwannoma of the Anterior Cranial Base in a Patient with Hereditary Hemorrhagic Telangiectasia.

Background: Olfactory schwannomas of the anterior cranial base (ACB) are rare tumors, and their association with hereditary hemorrhagic telangiectasia (HHT) has not previously been described. The majority of ACB schwannomas arise from the sinonasal tracts and may demonstrate intracranial extension. We report a case of an olfactory schwannoma-dense adherence to the basal frontal lobe.

Effect of topical mitomycin-C on total collagen deposits on the submucosa of intact vocal folds in swine.

Objective: To compare the effects of topical mitomycin-C at different concentrations on submucosal collagen deposition on the vocal folds of swine.

Methods: The animals were divided into three groups according to the composition of the topical solution to be applied to the vocal folds: 0.9% saline solution (control group); 4 mg/ml mitomycin-C (group 1) and 8 mg/ml mitomycin-C (group 2).
