ethmoid

While the frequencies of frontal and sphenoid sinus lesions did not show significant differences between the two groups (p>0.05), the frequencies of lesions of maxillary and ethmoid sinuses were significantly higher in the winter group compared to the summer group (p<0.05).

(2014) divided crista galli in three groups considering its relationships with cribriform lamina of the ethmoid bone: type I--crista galli situated entirely above the lamina cribriformis, type II--crista galli situated less than 1/2 of its height under the lamina cribriformis, type III--crista galli situated more than 1/2 of its height under the lamina cribriformis.

(3) Fungal sinusitis typically involves multiple sinuses with the most common being the ethmoid and maxillary sinuses.

CT scans showed substantial improvement of the ethmoid and maxillary sinuses (Figure, panel D); T-SPOT.TB results were negative (TB antigen - Nil = 0).

This is followed by the ethmoid sinus with a rate of 20-25%, maxillary sinus at 5-10%, and sphenoid sinus at a rate of 5-10% (2).

Endoscopic middle meatus examination showed an ill-defined ethmoid tumour mass not extending inferiorly.

They occur most frequently in frontal sinus followed by ethmoid and maxillary sinuses.

Skull base coronal thin-section CT scan showed a fracture in the left side of ethmoid plate, and MR cisternography revealed high-signal-intensity CSF column in the left side of the floor of anterior cranial fossa and sinus [[Figure 1]-case 1].

The dorsal nasal turbinate was the longest and extended from level of third transverse rugae of hard palate to level of cribriform plate of ethmoid bone and it continued rostrally as straight fold.

Previously, Propel mini was indicated solely for placement in the ethmoid sinuses, located just behind the bridge of the nose.

It markets two steroid releasing implants, PROPEL and PROPEL mini, clinically proven to improve surgical outcomes for patients with chronic sinusitis undergoing ethmoid sinus surgery.

The most common sites of origin for primary mucoceles were the ethmoid sinus (31.5%) and sphenoid sinus (31.5%).

The ethmoid lesion has entirely resolved and around 50 percent reduction in the size of the inferior frontal lobe mass.
