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.
Posteriorly, an opening of sphenoidal sinus opens into the sphenoidal sinus by an aperture high on the anterior wall the sinus; anteriorly, an opening of sphenoidal sinus opens into the roof of the nasal cavity via an aperture on the posterior wall of the sphenoethmoidal recess, just over the choana. [4]
Also known as a sphenoethmoidal air cell, an Onodi cell is a posterior ethmoidal air cell that lies superolateral to the sphenoid sinus, often extending into the anterior clinoid process. [9]

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 ...
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 ...
Olfactory mucosa lines about 5cm 2 of the posterosuperior parts of the lateral nasal wall. Parts of the nasal cavity lined by olfactory mucosa include: parts of the roof of the nasal cavity, the superior nasal concha and some upper parts of the middle nasal concha, parts of the nasal septum, and the sphenoethmoidal recess.
Frontal sinus. Each frontal sinus is situated between the external and internal plates of the frontal bone. [1] [2] Their average measurements are as follows: height 28 mm, breadth 24 mm, depth 20 mm, creating a space of 6-7 ml. [3]
