The tentorial notch (also known as the tentorial incisure or incisura tentorii) refers to the anterior opening between the free edge of the cerebellar tentorium and the clivus for the passage of the brainstem.

Anatomy and approaches to the posterior cranial fossa and posterior cranial base, including chapters on the fourth ventricle, tentorial incisura, foramen magnum,

Its anterior border is free and concave, and bounds a large oval opening, the tentorial incisure, through which pass the cerebral peduncles. The tentorial incisura (TI), an opening at the center of the tentorium, provides the only communication between the STS and the ITS. The TI is divided into the anterior, middle, and posterior However, the tentorial incisura is actually in relation to the midbrain. Anteriorly the incisura extends above the optic chiasm to the lamina terminalis, the middle incisural space is located Description The tentorial notch refers to the anterior opening between the free edge of the tentorium cerebelli and theclivus for the passage of the brainstem. It's located between the tentorial edges and communicates the supratentorial and infratentorial spaces.

Tentorial incisura

[TA] the triangular opening in the tentorium cerebelli through which the brainstem extends from the posterior into the middle cranial fossa. Synonym (s): incisura tentorii [TA], incisura of tentorium ☆ , notch of tentorium. Farlex Partner Medical Dictionary © Farlex 2012. Surgical excision of meningiomas involving the tentorial incisura is a significant technical challenge, mainly due to access, especially for medially located lesions, as well as their relationship to the brain stem, cranial nerves, temporal lobe, blood vessels, and venous sinuses. The microsurgical anatomy of the tentorial incisura was evaluated in 25 adult cadavers using X 3 to X 40 magnification.

The microsurgical anatomy of the tentorial incisura was evaluated in 25 adult cadavers using × 3 to × 40 magnification.

Results. We distinguished 4 types of tentorial incisura configuration (А, В, С, D) based on the data of craniometric and morphometric analysis. It was stated that the mean values of TI parameters for mesocephalic cranium were determined by configuration of tentorial apex.

The early exposure of these structures provided by the SCTT approach allows for their protection by microdissection away from the tumor before significant tumor debulking is performed and the surgical field is obscured by Ten cadaver heads were analysed to reveal the variations of spatial anatomy around the tentorial incisura. The lateral tentorial incisura (lateral to brain stem) was situated at the level of pontomesencephalic junction and nearest to the brain stem along its course. The shortest distance between them averaged 1.0mm (0-4mm). 1991-05-01 · Huang and Shen: Tentorial Subdural Hemorrhage 175 C D Figure 4. Hemorrhage over the retroc'erebellar space in Patient 7.

Anteriorly the incisura extends above the optic chiasm to the lamina terminalis, the middle incisural space is located It can be viewed as four types: (1) Gothic arch — a plane of the incisura showing the full contour of the tentorium from the anterior clinoid process to the apex of the tentorial notch, (2) V configuration — a plane of the torcular showing with the tentorium traveling medially, (3) Diverging bands — a plane below the torcular showing where the tentorium departs posterolaterally towards ten·to·ri·al notch.

The tentorial incisura is located between the tentorial edges and is the only site of communication behind the supra and infratentorial spaces.

tentorial DVAF due to a variety of presentations [4–8, 12, 13]. The optimal surgical strategy for tentorial DAVF depends on the anatomic location of the fistula and the specific characteristics of the arterial supply and venous drainage. Although the subtemporal approach was used in some reported DAVF around the tentorial incisura, to date, Ten cadaver heads were analysed to reveal the variations of spatial anatomy around the tentorial incisura.
