Sphenoid sinus septations and their interconnections with ...
In 903 patients in 287 cases of sphenoid sinuses, we were able to identify at least one septum that had an interconnection with the ICA protuberance within the sphenoid sinus. This gives the risk of interconnection between the septum and the ICA protuberance of 32%.
Sphenoid sinus - Wikipedia
The sphenoid sinus is a paired paranasal sinus in the body of the sphenoid bone. It is one pair of the four paired paranasal sinuses. [1] The two sphenoid sinuses are separated from each other by a septum. Each sphenoid sinus communicates with …
Sphenoid sinus anatomical variants and pathologies
2023年5月18日 · The sphenoid sinus (SS) is one of the four paired PNSs within the sphenoid bone body divided by the septum. The sphenoid sinus ostium is placed in the cranial part of the intranasal surface. The spheno-ethmoid recess (SER) is the drainage pathway of the posterior ethmoidal air cells and sphenoid sinuses into the superior nasal meatus.

2024年6月30日 · The sphenoid sinuses are paired spaces formed within the body of the sphenoid bone, communicating with the roof of the nasal cavity via the sphenoethmoidal recess in its anterior wall. The two hemisinuses are separated by a …
Risky anatomical variations of sphenoid sinus and surrounding ...
2022年9月3日 · This study aimed to examine the relationship between the sphenoid sinus (SS) and surrounding vital structures such as the internal carotid artery (ICA) and optic nerve canal (ONC) as well as the types of attachment of the sphenoidal septa onto these structures.
An Analysis of Anatomic Variations of the Sphenoid Sinus ...
Analysis of 90 patients' CT scans on axial, coronal and sagittal planes with 1 mm slices, evaluating lateral and posterior extensions of pneumatization of the SS, deviation of the sphenoid septum, presence of septations and their relationship to the parasellar and paraclival segments of the internal carotid artery (psICA and pcICA, respectively).
Sphenoid sinuses: pneumatisation and anatomical variants—what …
2020年5月11日 · SS are paired air cavities located within the body of the sphenoid bone, divided by a main septum. They are midline structures placed anterior to the clivus, and posterior to the superior meatus of the nasal cavity. The pituitary fossa and the optic chiasm lie above, and the nasopharynx is located below the SS.
Septum of sphenoidal sinuses - e-Anatomy - IMAIOS
The septum of sphenoidal sinuses is a bony partition that divides the right and left sphenoidal air sinuses. Although it’s located in the middle, it often tilts slightly to one side. This tilt makes the two sinuses irregular in shape and being of unequal sizes.
Complex anatomy of the sphenoid sinus: a radiographic study and ...
Septal involvement of the carotid artery occurs frequently. Pneumatization patterns are potentially disorienting, and awareness of the sinus's posterior and lateral extensions is critical. Keywords: endoscopic surgery; skull base; sphenoid. Objectives Nasal endoscopic approaches to the sphenoid sinus are challenging.
