Huge Choanal Polyp 6

Description : All that remained was to located and removed the site of origin of the polyp within the left maxillary sinus. Inspection of the interior of the maxillary sinus can usually be accomplished by looking through natural ostium into the sinus with an angled telescope [30, 70. 90. or 120 degree].

When inserting the more highly angled telescopes into the middle meatus, it is sometimes difficult to position the tip of the telescope properly while looking through the scope. This next series of photographs illustrates a simple technique for positioning angled telescopes using the outer sheath of the maxillary sinus trocar. The trocar sheath is placed over a 0 degree 4 mm endoscope and using the scope positioned so that the opening on the “shovel” is located immediately lateral to the maxillary sinus ostium.
