Imaging for endoscopic sinus surgery in adults [PDF]

, 2002
Computerized tomography (CT) offers the gold standard in terms of imaging the extent of disease and the fine detailed anatomy, both pre-requisites to the safe practice of endoscopic sinus surgery. Neither plain X-rays nor magnetic resonance imaging (MRI)

Validity and sensitivity of a human cranial finite element model: Implications for comparative studies of biting performance [PDF]

, 2015
Finite element analysis (FEA) is a modelling technique increasingly used in anatomical studies investigating skeletal form and function. In the case of the cranium this approach has been applied to both living and fossil taxa to (for example) investigate

Frontal Sinus “Hump”: An Anatomical Risk Factor for Anterior Skull Base Injury in the Endoscopic Modified Lothrop Approach (Outside-In Frontal Drill-Out)

Case Reports in Otolaryngology, 2021
Skull base injuries caused by the outside-in frontal drill-out technique have not been reported. In this report, we chose an outside-in approach to open the frontal sinus for olfactory neuroblastoma resection.

Complications of frontal defects [PDF]

, 1987
A case where the severe course of an orbital phlegmon led to a functionally and cosmetically poor condition is presented. Thirty-five years later, it was possible to achieve a satisfactory result through several operations performed with ...

Necessary Factors for Efficient Frontal Sinus Irrigation After Endoscopic Sinus Surgery: A Systematic Review

Journal of Otolaryngology - Head and Neck Surgery
Objective The frontal sinus remains a challenging site for irrigation due to its position relative to the nostril and ethmoid sinus. This study aims to summarize the necessary factors for efficient irrigation of the frontal sinus after endoscopic sinus ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Osteomyelitis of right frontal sinus anterior wall [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2008
Introduction The paper describes a very rare, isolated exocranial complication of the purulent frontal sinus inflammation. Frontal bone osteomyelitis occurs either in the course of an acute episode or during the exacerbation of a chronic disease.

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.
