Motion analysis for objective evaluation of psychomotor skills in Endoscopic Sinus Surgery.

Background: This study aims to digitalize surgical maneuvers in ESS using a motion capture system under standardized conditions provided by 3D printed-sinus models.

Methodology: Forty-seven otolaryngologists performed ESS on 3D printed models manufactured from computed tomography (CT) images of actual patients. Participants were classified to 3 groups according to the objective structured technical skills assessment score.

Promoting the Efficacy of Deferiprone-Gallium-Protoporphyrin (IX) against Intracellular Infection with Lipid Liquid Crystalline Nanoparticles.

Nontuberculous mycobacteria (NTM) are among the recalcitrant bacterial strains that cause difficult-to-treat infections for patients with chronic underlying pulmonary conditions. The bacteria's intrinsic resistance to various antibiotics and their ability to infect macrophages enable them to overcome both the host immune response and standard antibiotics. Unconventional approaches to treating NTM-mediated infections are required.

Mucosal Spread of Sinonasal Adenocarcinoma into the Nasolacrimal Duct Without Bony Erosion of the Nasolacrimal Canal: A Case Report.

Sinonasal malignancy is a rare but recognized cause for nasolacrimal obstruction leading to epiphora. While direct mucosal spread through the nasolacrimal duct can occur in benign sinonasal tumors such as inverting papilloma, the same phenomenon has not been described in malignant lesions. The authors present a case of a low-grade nonintestinal type sinonasal adenocarcinoma centered on the inferior meatus of the sinonasal cavity, showing mucosal invasion into the nasolacrimal duct with bony expansion but no erosion of the nasolacrimal canal.

Graded Eyelid Crease Approach to the Superior Orbital Apex: An Anatomical Study.

Purpose: To describe a graded eyelid crease approach to access the superior orbital apex, and to quantify the working space enabled with the sequential release of structures along the superior orbital rim.

Methods: Cadaveric dissection study of 7 cadaver heads (14 orbits). This technique involved a subperiosteal approach to the superior orbital apex.

Evaluation of mucosal barrier disruption due to Staphylococcus lugdunensis and Staphylococcus epidermidis exoproteins in patients with chronic rhinosinusitis.

Background: Chronic rhinosinusitis (CRS) is a persistent inflammatory condition of the sinus mucosa. While Staphylococcus aureus has been shown to play a significant role in mucosal barrier disruption in CRS patients, coagulase-negative staphylococci (CoNS) such as Staphylococcus epidermidis and Staphylococcus lugdunensis are also implicated in CRS pathophysiology. This study investigates the effects of exoproteins secreted by planktonic and biofilm forms of clinical isolates of S.
