Relation between volume of sphenoid sinuses and protrusion of Vidian nerve: possible applications to Vidian neurectomy [PDF]

, 2020
Purpose Vidian neurectomy is a surgical procedure applied to different pathological conditions, including chronic rhinitis and sphenopalatine neuralgia. The choice of the correct surgical approach depends upon the possible protrusion of Vidian nerve into

Innervation of the tubarial glands: A hypothesis‐driven anatomical review

The Anatomical Record, EarlyView.
Abstract The tubarial glands have been described as a macroscopic bilateral glandular complex in the posterolateral nasopharynx near the torus tubarius and the pharyngeal opening of the Eustachian tube. Since their recognition on prostate‐specific membrane antigen‐based imaging, their anatomical classification has remained debated, with converging ...

The transnasal endoscopic management of spontaneous cerebrospinal fluid rhinorrhea from the lateral recess of the sphenoid sinus

The Egyptian Journal of Otolaryngology, 2016
En Abstract Background Spontaneous cerebrospinal fluid (CSF) rhinorrhea from the lateral recess of the sphenoid sinus is surgically challenging. Sternberg’s canal has stirred great controversy as the potential source. The aim of this study was to present

A New Perspective on the Cavernous Sinus as Seen through Multiple Surgical Corridors: Anatomical Study Comparing the Transorbital, Endonasal, and Transcranial Routes and the Relative Coterminous Spatial Regions

Brain Sciences, 2023
Background: The cavernous sinus (CS) is a highly vulnerable anatomical space, mainly due to the neurovascular structures that it contains; therefore, a detailed knowledge of its anatomy is mandatory for surgical unlocking.

Three-dimensional bone CT reconstruction anatomy of the vidian canal

Rhinology journal, 2013
Objectives: To examine the anatomical features of the anterior opening of the vidian canal using three-dimensional (3D) computed tomography (CT) images of the bone. Methods: We reviewed 62 patients who had undergone bilateral vidian neurectomies. One hundred and twenty-four vidian canals and their surrounding anatomies were analyzed.
