2) However, this pathway is usually not easily visualized from within the ethmoid sinus as an ostium
leading into the nasal cavity.
No origin of the coronary ostium
arising from the left sinus Valsalva was imaged.
Using the lighted guidewire to illuminate the interior of the frontal sinus following dilation of the ostium
allows for excellent views postdilation.
David Blossom, Vice President of Commercial Operations at Cappella Medical, said, "The Cappella Sideguard coronary sidebranch technology was developed to protect the ostium
of the sidebranch which, in turn, will preserve the sidebranch coronary artery using a proprietary, easy-to-use, delivery system.
of the ethmoid bulla is usually difficult to locate even with the use of a telescope.
A 30[degrees] telescope was then passed into the frontal recess, and an adequate ostium
was clearly identified (figure, F).
Michael Gilmore, Vice President of R&D, Clinical, and Regulatory at Cappella Medical, said, "The Cappella Sideguard coronary sidebranch technology was developed to protect the ostium
of the sidebranch which, in turn, will preserve the sidebranch coronary artery.
Like other aerated cells, a concha bullosa possesses a mucociliary transport system, with the ostium
connecting the airy cell lumen to the frontal recess.
Giuseppe Massimo Sangiorgi at the Policlinico di Modena - University of Modena and Reggio Emilia, in Modena, Italy stated, "The side branch ostium
anatomy requires a unique technology solution to effectively manage and optimize treatment.
After the lateral half of each concha bullosa was resected, it was found that the ostium
located in the lateral posterior portion of each drained directly into the middle meatus.
The Ostial Pro facilitates precise stent implantation of aorto-ostial stents by identifying the true ostium
Sphenochoanal polyps are rare, benign, solitary masses that arise from the sphenoid sinus, exit through the sphenoid ostium
, pass across the sphenoethmoid recess, and extend into the choana.
