Nov 14, 2024 · The skull base can be subdivided into three regions: the anterior, middle, and posterior cranial fossae. (See the image below.) The anterior fossa primarily includes the frontal lobe...

Jul 6, 2024 · The base of the skull is a bony diaphragm composed of a number of bones - from anterior to posterior: These bones are separated from each other by sutures. Sutures which take part in the formation of the skull base include:

CT and MRI are the imaging modality of choice for evaluation of skull base anatomy and pathology. This brief review article discusses common skull base pathologies along with the relevant anatomy and imaging techniques. The ASB forms the bottom of the anterior skull, separating the anterior cranial fossa from the paranasal sinuses and the orbits.

Jun 10, 2019 · The anterior skull base is an important anatomic structure that separates the cranial cavity above and the sinonasal cavity and the orbits below. This region is frequently breached by aggressive disease, such as malignancy and infection.

Mar 25, 2024 · The anterior skull base is the bottom of the anterior skull, separating the anterior cranial fossa from the paranasal sinuses and the orbits. The anterior skull base (Figs 3.26.1 – 3.26.6) is formed by three bones – frontal, ethmoid and sphenoid.

In this chapter, we discuss the important anatomical features of the nasal cavity, orbit, and anterior skull base, variations in anatomy, and the importance of surgical landmarks to remain safe during endoscopic surgery.

Let’s explore the bones constituting the base of the skull, highlight its significant features, including the sulci, grooves, and foramina, and underscore its clinical significance. Bones and fossae of the skull base. The skull base, a complex anatomic area, comprises several bones: the ethmoid, sphenoid, frontal, occipital, and temporal.

Mar 28, 2017 · This article briefly discusses the imaging approach to lesions of the anterior skull base. A brief review of normal anatomy and imaging techniques is followed by a discussion about common neoplastic and non-neoplastic pathologies involving this region.
