The natural ostium of the sphenoid sinus is located at its superior aspect anteriorly and drains into the sphenoethmoid recess.
These are: (1) the intersphenoidal synchondrosis (iss), (2) intrapostsphenodial synchondrosis (its), (3) rostrum ossicle of Bertin synchondrosis, (4) interplanum sphenoidal suture, (5) sphenoethmoid suture, and (6) sphenosquamosal suture (Table 2).

The parameters correlated in our study include middle turbinate, middle meatus, bulla ethmoidalis, hiatus semilunaris, frontal recess and sphenoethmoid recess.
In-office flexible nasal endoscopy revealed a healthy-appearing mucosa in the left sphenoethmoid recess.
Sphenochoanal polyps are rare, benign, solitary masses that arise from the sphenoid sinus, exit through the sphenoid ostium, pass across the sphenoethmoid recess, and extend into the choana.
The nasal mass was seen occupying the sphenoethmoid recess; it had arisen from the nasal septum on the posterior part of the vomer (figure 1).
Endoscopic examination revealed that the middle meatuses were unremarkable, but examination of the area of the right sphenoethmoid recess revealed purulent discharge over the anterior face of the sphenoid sinus (figure, B).
Instead, it was attached to the cribriform plate and the sphenoethmoid recess by a stalk.
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.
