Summary. location: the central body of the sphenoid bone anteroinferior to the sella turcica. blood supply: posterior ethmoidal and sphenopalatine arteries. innervation: posterior ethmoidal nerve and the orbital branch of the pterygopalatine ganglion.

1 kwi 2021 · The paranasal sinuses are air filled extensions of the respiratory part of the nasal cavity. There are four paired sinuses, named according to the bone they are located in; maxillary, frontal, sphenoid and ethmoid.
Sphenoidotomy, a form of endonasal surgery, may be done to enlarge the sphenoid sinus, usually in order to drain it. [ 8 ] The sphenoid sinus should be distinguished from an Onodi cell , an anatomic variant that is the rearmost ethmoidal air cell .
The sphenoid sinus (SS) is one of the four paired PNSs within the sphenoid bone body divided by the septum. The sphenoid sinus ostium is placed in the cranial part of the intranasal surface. The spheno-ethmoid recess (SER) is the drainage pathway of the posterior ethmoidal air cells and sphenoid sinuses into the superior nasal meatus.
11 lut 2023 · The superior meatus drains for the sphenoid and posterior ethmoid sinuses. The middle meatus drains the frontal, anterior ethmoid, and maxillary sinuses. The inferior meatus contains the orifice of the nasolacrimal duct.
11 maj 2020 · The sphenoid sinus drains into the nasal cavity through the spheno-ethmoid recess (SER) which is a thin space in the nasal cavity, located between the intranasal aspect of the sphenoid sinus and the superior concha. SER represents the drainage pathway of the posterior ethmoid air cells and sphenoid sinus into the superior nasal meatus (Fig. 2).
The sphenoidal sinus drains into the sphenoethmoidal recess superior to the superior concha. In up to 52% of cases, the supreme nasal concha is present superior to the superior nasal concha. Arteries supplying the nasal cavity includes anterior and posterior ethmoid (from ophthalmic), sphenopalatine and greater palatine (from maxillary), and ...
