The term skull topography refers to the detailed study of its external and internal surfaces. This also includes understanding the complex arrangement of various regions and fossae that form the bony framework of the head. This field of study is crucial for understanding how the skull supports and protects the brain and structures connected to it, houses the sensory organs, and interacts with the rest of the body.

As mentioned, the topography of the skull encompasses both external and internal aspects of the skull, revealing its anatomical features and their functional relationships. The key topographical regions of the skull include the following:

• Cranial bases (internal and external cranial bases)
• Fossae (unpaired anterior cranial fossa, middle cranial fossa, posterior cranial fossa, and paired temporal fossae, infratemporal fossae, and pterygopalatine fossae)
• Orbits
• Nasal cavity
• Paranasal sinuses (maxillary sinuses, frontal sinuses, ethmoid air cells, and sphenoid sinuses)

A thorough understanding of skull topography not only enhances anatomical knowledge but also provides insights into various clinical conditions and surgical approaches. It is crucial for grasping the functional relationships between different anatomical structures and their clinical significance.
