The nasal sinus located between the nose and the orbits is the ethmoid sinus. This anatomical structure consists of a group of air cells situated within the ethmoid bone, which lies at the roof of the nasal cavity and between the eyes. The ethmoid sinuses play a crucial role in the respiratory system and contribute to the overall structure of the skull.

They are significant for several reasons: they help to lighten the weight of the skull, provide resonance to the voice, and produce mucus that helps to moisten the nasal cavity. The close proximity of the ethmoid sinuses to the orbits (eye sockets) is particularly important in clinical contexts, as infections or inflammation in these sinuses can have implications for ocular health. This anatomical relationship is a fundamental concept in surgical technology and medical practice, facilitating procedures and assessments involving the sinus and orbital regions.
