Pneumatized superior turbinate: Pneumatization of superior turbinate can occur from posterior ethmoid cells. Of the 48% incidence reported by Ariyurek OM et al46 in their study, 40% of cases showed pneumatization in the form a small air cell minimally expanding the superior Conchahe called this as a grade I pneumatization.
The frontal recess may be pneumatized by various anterior ethmoid cells, which are collectively known as frontal recess cells.
To obtain tissue for histopathologic examination, the left posterior ethmoid cells and sphenoid sinus were opened endoscopically.
Posterior Ethmoids: A small opening was made through the ground (basal) lamella into the posterior ethmoid cells. An adequate opening is made into the posterior ethmoids with an upturned curette, curved suction, or ball-tip probe.
HALLER CELLS: Haller's cell is the pneumatization of the anterior ethmoid cells into the roof of the maxillary sinus extending into the floor of the orbit.
The posterior ethmoid cells, which are located posterior to the basal lamella, drain into the superior meatus.
These findings of ossification were described as extending into the right ethmoid cells to the lamina papyracea with no extension into the orbit (figure, B).
Computed tomography (CT) of the sinuses revealed chronic bilateral ethmoid sinusitis with totally opacified ethmoid cells. The patient underwent bilateral endoscopic ethmoidectomies.
(5) The posterior ethmoid cells are separated from their anterior counterparts by the ground lamella of the middle turbinate, which attaches laterally to the lamina papyracea of the ethmoid bone.
The posterior ethmoid cells were normal, as was the ostiomeatal opening on each side.
