This review identifies 31 anatomical triangles of the skull base, serving as crucial landmarks for surgeons. These triangles enhance orientation and confidence during complex skull base procedures.
Area of Science:
- Neurosurgery
- Anatomy
- Surgical Navigation
Background:
- Skull base surgery demands intricate anatomical knowledge.
- Anatomical triangles are vital landmarks for surgical navigation.
- Existing literature lacks a consolidated resource on skull base triangles.
Purpose of the Study:
- To compile a comprehensive review of anatomical triangles in the skull base.
- To serve as a detailed resource for surgeons and anatomists.
- To enhance understanding and application of skull base triangles in microsurgery.
Main Methods:
- Conducted a literature review using PubMed and reference list searches.
- Identified and cataloged 31 distinct anatomical triangles of the skull base.
- Categorized triangles by cranial fossa or extracranial location.
Main Results:
- Identified 31 unique anatomical triangles of the skull base.
- Triangles are categorized into cranial fossae or extracranial regions.
- The review details borders, contents, and surgical applications for each triangle.
Conclusions:
- This review provides a comprehensive catalog of skull base triangles.
- The identified triangles serve as essential navigational aids in skull base surgery.
- Enhanced awareness of these triangles can improve surgical precision and outcomes.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
