Intersect ENT announced that the company has received approval from the FDA for a new Straight Delivery System for use to place its PROPEL Mini steroid releasing sinus implant in the ethmoid sinus
. PROPEL Mini helps maintain the sinus opening while delivering mometasone furoate directly where it is needed, improving outcomes of frontal (behind the forehead) and ethmoid sinus
Mucosal thickening was the most common abnormality (37.1%), and the maxillary sinus was the most commonly affected sinus (37.7%), followed by the anterior ethmoid sinus
Cancers were located in the ethmoid sinus
(n = 3), nasal cavity (n = 2), sphenoid sinus (n = 2), and maxillary sinus (n = 1); in our series....
Tumours were present in nasal cavity (n=4), ethmoid sinus
(n=3) and maxillary sinus (n=1).
Among the PNS most commonly involved was maxillary sinus (35 [70%]) followed by ethmoid sinus
(20 [40%]), sphenoid sinus (17 [34%]), and frontal sinus (12 [24%]).
Their etiology is unknown, and they most commonly involve the frontal and ethmoid sinus
. We present an exceedingly rare localization of osteoma within the cavity of a concha bullosa of the middle turbinate in a 38-year-old woman with frontal headaches and right-sided facial pain.
(3) reported that mucoceles arose most frequently from the ethmoid sinus
in their paranasal sinus mucocele case series, which was composed of 10 pediatric patients.
 The remaining 10-20% are intestinal-type adenocarcinoma, which mostly occur in the ethmoid sinus
.  There have been fewer than 500 reported cases of primary squamous cell carcinoma of the ethmoid sinus
in the English literature.
(16) nasal fossae and maxillary, occurring less in the ethmoid sinus
Development of the ethmoid sinus
and extramural migration: the anatomical basis of this paranasal sinus.
It markets two steroid releasing implants, PROPEL and PROPEL mini, clinically proven to improve surgical outcomes for patients with chronic sinusitis undergoing ethmoid sinus
The most common sites of origin for primary mucoceles were the ethmoid sinus
(31.5%) and sphenoid sinus (31.5%).
