In Vivo Imaging of the Olfactory Epithelium Using Confocal Laser Endomicroscopy

This research is being done to better characterize the part of the nose that helps people smell. Currently, the only ways to study smell loss mostly rely on how people report it, rather than being able to see the underlying structures directly. In this study, the team will use a special microscope (Confocal Laser Endomicroscopy (CLE)), originally developed for brain tissue, to look at the part of the nose that helps to detects smell. The study team hopes to identify the tiny structures in that area and see how they might be different in people who have smell loss compared to those who do not. Participation in the study includes completing a smell test (Sniffin' Sticks Extended test), a cognitive screening test, and two questionnaires.

Radiological and Surgical Analysis of Frontal Recess Variations in Endoscopic Sinus Surgery

Introduction The frontal recess is a narrow and anatomically variable region that forms the frontal sinus drainage pathway. Variations in its anatomy, particularly those related to the agger nasi cell and other frontal recess cells, can impair frontal sinus drainage and contribute to the development of frontal sinus disease. High-resolution computed tomography and endoscopic evaluation are essential for identifying these variations and planning endoscopic sinus surgery. A thorough understanding of frontal recess anatomy is crucial for achieving adequate frontal sinus drainage, improving surgical outcomes, and minimizing complications due to the close proximity of the orbit and skull base. The Study aim to evaluate the anatomical variations of the frontal recess using radiological and surgical assessment and determine their significance in the management of frontal sinus disorders during endoscopic sinus surgery.
