sphenoethmoid recess

[sfē′nō·eth′moid]
Etymology: Gk, sphen, wedge, eidos, form; L, recedere, to retreat
a narrow opening in the lateral wall of the nasal cavity bounded above by the cribriform plate of the ethmoid and the body of the sphenoid and below by the superior nasal concha. It opens into the sphenoidal sinus of the skull.

Collectively, these structures form what is known as the sphenoethmoid recess, which serves as a common drainage pathway for the posterior ethmoid and sphenoid sinuses.
Anterior rhinoscopy does not allow for visualization of the sphenoethmoid recess, but nasal endoscopy provides a clear view of the sphenoethmoid recess and the postnasal space.
