It is orientated almost sagitally and runs from anterosuperior to posteroinferior and forms the medial border of the ethmoid infundibulum
The high success rate of both experienced and inexperienced XprESS users in this study confirms that transnasal access and dilation of the ethmoid infundibulum
and natural maxillary opening is repeatable without tissue removal when using the XprESS sinus balloon device.
The presentation of an enlarged pneumatized bulla ethmoidalis (BE) that obstructs the ethmoid infundibulum
has not been previously reported.
It also enhanced the access for endoscopic examination and cleaning of maxillary sinus, ethmoid infundibulum
, and frontal recess can be achieved.
In the report titled, "Impact of chronic rhinosinusitis on work productivity through one-year follow-up after balloon dilation of the ethmoid infundibulum
," subjects reported the quantity, quality and timeliness of their work output was limited 33% of the time due to CRS, and significantly impacted their absentee rate.
3) Yanagisawa and his group also have stated that the ostium of the ethmoid bulla is often found in the hiatus semilunaris superior, but that it can also be found in the anterior or lateral wall of the bulla, the ethmoid infundibulum
, the hiatus semilunaris inferior, or the retrobullar recess.
9) have defined the osteomeatal complex as a complex including the maxillary sinus ostium, ethmoid infundibulum
and middle meatus; in other words, as the final site of drainage from the frontal and maxillary sinuses and anterior ethmoidal cells.
1 FinESS dilates the ethmoid infundibulum
, the main drainage pathway in the osteomeatal complex (OMC), with balloon dilation which preserves tissue, bone and ciliary function.
The drainage pathway, or ostium, of a pneumatized uncinate process may open directly into the middle meatus, the ethmoid infundibulum
or, as seen in this patient, into the ethmoid sinus.
The study demonstrated that direct access and balloon dilation of the maxillary sinus ostia and ethmoid infundibulum
under local anesthesia can be performed with little pain or bleeding and patients resume normal activity within 1-2 days.
Computed tomography (CT) of the sinuses revealed minimal findings, with only a slight clouding in the left ethmoid infundibulum
Entellus Medical's treatment is designed to enlarge the maxillary sinus ostium and ethmoid infundibulum
