The Role of Morphologic and Functional Imaging in Pretreatment Assessment

open access: yes, 2020
Anterior skull base (ASB) tumors can be classified into three groups according to their site of origin: (1) sinonasal neoplasms involving or extending through the anterior cranial base; (2) neoplasms which arise from the bony framework of the base itself;

Patient‐Mounted Neuro Optical Coherence Tomography for Targeted Minimally Invasive Micro‐Resolution Volumetric Imaging in Brain In Vivo

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

The role of midfacial degloving in modern rhinological practice

open access: yes, 1999
The midfacial degloving approach has been available for twenty five years and is slowly increasing in popularity in the management of extensive benign lesions of the sinonasal region, for selected malignancy in this area and to afford access to the ...

High‐Resolution Genomic Characterization of WAGR Spectrum Disorder: Insights From a Novel Cohort and Literature Synthesis, and Validation of Patient‐Reported Data

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT WAGR spectrum disorder (WAGRSD) is an ultra‐rare congenital disorder caused by heterozygous deletion of chromosome 11p13. While classically associated with Wilms tumor, Aniridia, Genitourinary anomalies, and a Range of developmental delays, accurate delineation of the deletion is critical for prognosis because the phenotypic spectrum extends ...

Endoscopic surgery of the paranasal sinuses and skull base neoplasms with the use of the computerassisted navigation system (CANS) in pediatric practice

open access: yes, 2016
Background: In the last 10 years, the use of computer-assisted navigation systems (CANS) in endo-nasal endoscopic surgery of the paranasal sinuses and skull base in adults has been well studied.

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Sinonasal neoplasms again

open access: yes, 2013
Sinonasal neoplasms are uncommon neoplasms, accounting for only 1% of all malignancies and only 3% to 5% of all head and neck malignancies. In 2010 Rhinology published the European position paper on endoscopic management of tumours of the nose, paranasal

Biofilm Exoproteins From Staphylococcus Species Impede Re‐Epithelialization of Nasal Epithelial Cells During Wound Healing and Cease Ciliary Beat Frequency

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Chronic rhinosinusitis (CRS) is an inflammatory disease with many different contributing factors, including bacterial infection. CRS patients are typically managed with medical therapies; however, these treatments frequently fail, leaving surgery as the only viable option.

Advance on endoscopic skull base surgery

open access: yes, 2019
Endoscopic skull base surgery started from 1990s, and has undergone fast development in the past 20 years. It has involved various skull base regions from the anterior skull base to the craniovertebral junction (CVJ) and jugular foramen, including intra-

Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting
