Choanal Polyp Left 3

Description : We now know that the majority of choanal polyps arise from a portion of the lining of the maxillary sinus. If this area of origin is not completely removed, then the choanal polyp will recur within a relatively short time interval.

For this reason, the interior of the maxillary sinus must be carefully inspected.

This can usually be accomplished by looking "backwards" into the sinus using angled telescopes positioned in the middle meatus directly medial to the natural ostium of the maxillary sinus.

One of the main advantages of this particular IGS systems is the ability to use a clamp on attachment onto which a "star
containing three silver reflective spheres is attached. Once this new piece of equipment [in this case eight curved suction tip] has been registered, its tip can be tracked with the image guidance system.
