The sphenoethmoidal recess is a small triangular space superior to the superior nasal meatus of the nasal cavity into which the sphenoidal sinus [1] [2] [3] opens. [4] The sphenoethmoidal recess is situated supero posterior to the superior nasal concha, [3] [2] between the superior nasal concha and the anterior aspect of the body of the sphenoid bone.

[2]: 500 One study found that carotid canal protrudation into the sphenoid sinus wall was present in 23.9–32.1% of males and 35.5–36.2% of females, dehiscence in carotid canal was detected more in females (34%) than in males (22%), optic canal protrudation was 33.3 and 30.5% in males and females, and optic canal dehiscence was detected in ...
The cells are located within the lateral mass (labyrinth) of each ethmoid bone and are variable in both size and number. [1] The cells are grouped into anterior, middle, and posterior groups; the groups differ in their drainage modalities, [ 2 ] though all ultimately drain into either the superior or the middle nasal meatus [ 3 ] of the lateral ...
Above and at the back of the superior concha is the sphenoethmoidal recess which the sphenoidal sinus opens into. The superior meatus occupies the middle third of the nasal cavity’s lateral wall. The middle meatus is the middle-sized and located nasal opening, lying underneath the middle concha and above the inferior concha where the meatus ...
The superior nasal concha is situated posterosuperiorly to the middle nasal concha.It forms the superior boundary of the superior nasal meatus.Superior to the superior nasal concha is the sphenoethmoidal recess where the sphenoid sinus communicates with the nasal cavity; the sphenoethmoidal recess is interposed between the superior nasal concha, and (the anterior aspect of) the body of ...
