It's basically an ad for Instatrak and that particular practise.

Some surgeons like Instratak, but some very prominent and experienced ones do
not (except for revision surgery).

While it does help an inexperienced surgeon from totally losing track of where
he is with his instrument,  it also reduces the precision with which he cuts by
a couple of millimeters, relative to the conventional method.

It actually reduces precision?!?!?!?

Yes it uses computed location and its precision is 3 mm.

By eye, a skilled surgeon gets better than that.

On the other hand, it is great at telling the surgeon which part of the nose
and sinus he is at, and so reduces *gross* errors which can occur if thesurgeon
gets "lost".

I had modified Lothrop surgery performed last May, and the surgeon used the
Insta-Trak system.  He is one of the pioneers of endoscopic surgery (Dr.
Stankiewicz at Loyola University Medical Center).  The Lothrop has
traditionally been an external entry.  As you have indicated,  the
Insta-Trak made the procedure much less risky.  Here is a link:

It won't make a mediocre surgeon better, but can be a good tool in the hands
of a good surgeon.

Correct.  Some of the great ones like it and some do not, as Dr. Grossan
said......

It actually depends on the surgeon. In our group we like it and use it.
