Nasal Mucosa Regeneration After Reboot Surgery: Electron Microscopy and Histology Insights in CRSwNP

open access: yesThe Laryngoscope, EarlyView.
CRSwNP often requires multiple treatments, with monoclonal antibodies (mAbs) and endoscopic sinus surgeries used to manage resistant cases. This study focused on five patients undergoing reboot surgery, analyzing mucosal regeneration through biopsies and clinical outcomes over 24 months. It revealed complete non‐scarred regeneration of the nasal mucosa,

Endoscopic navigation in the absence of CT imaging [PDF]

open access: yes, 2018
Clinical examinations that involve endoscopic exploration of the nasal cavity and sinuses often do not have a reference image to provide structural context to the clinician. In this paper, we present a system for navigation during clinical endoscopic exploration in the absence of computed tomography (CT) scans by making use of shape statistics from ...

A CT-based deep learning system for automatic assessment of aortic root morphology for TAVI planning [PDF]

open access: yesarXiv, 2023
Accurate planning of transcatheter aortic implantation (TAVI) is important to minimize complications, and it requires anatomic evaluation of the aortic root (AR), commonly done through 3D computed tomography (CT) image analysis. Currently, there is no standard automated solution for this process.

Factors Affecting Nasal Discharge in Chronic Rhinosinusitis Patients

open access: yesThe Laryngoscope, EarlyView.
This study aimed to identify patient‐specific factors influencing the severity of nasal drainage in chronic rhinosinusitis (CRS) patients. It found that postnasal discharge (PND) was the most severe symptom, with female gender, CRS without nasal polyps, prior endoscopic sinus surgery, and allergies significantly associated with severe PND.

Development of an Open‐Source Algorithm for Automated Segmentation in Clinician‐Led Paranasal Sinus Radiologic Research

open access: yesThe Laryngoscope, EarlyView.
The purpose of this study was to validate and provide an open‐source segmentation algorithm of paranasal sinus CT scans for the otolaryngology research community. This can be used for further AI‐based analysis and radiomic analysis in future research. ABSTRACT Objective Artificial Intelligence (AI) research needs to be clinician led; however, expertise
