Guided Sinus Surgery
Introduction
to the InstaTrak System
Why
your surgeon has chosen the InstaTrak System for your sinus
surgery
The InstaTrak System from Visualization Technology, Inc., integrates CT scans
with a sophisticated guidance system. Highly accurate visual updates will
guide your surgeon at every step of the procedure, without dependence on limited
visual ability and no longer restricted by the endoscopes telescopic
view. Your surgeon will be able to see the surrounding anatomy and the instruments
as the procedure is being performed.
Your surgeon will explain the procedure to you. If you have any questions
about the surgery or the use of the InstaTrak System during surgery, ask your
surgeon.
How
the InstaTrak System works
The InstaTrak System uses a computer, specialized software and electromagnetic
tracking system to help your surgeon perform procedures as precisely as possible.
The System software builds a computerized model of your skull anatomy
with CT scans taken prior to your surgery. This model will act as a three-dimensional
road map for your surgeon. The tracking system links the surgical instruments
that will be used during the procedure to the computer. The instruments
will appear on the computer display screen as a set of cross hairs which
move through the computerized model of your skull. This will allow your
surgeon to see the exact location of the surgical instruments in direct
relation to areas of your skull anatomy that cannot be seen through the
endoscope.
About the
InstaTrak System for endoscopic sinus surgery
Your surgeon has chosen to use the InstaTrak System for your sinus procedure.
This brochure will describe the System, and familiarize you with some
of the medical terms that you may encounter in the course of your treatment.
The InstaTrak System is a three-dimensional guidance system used in minimally
invasive image-guided surgery. When used to repair the sinuses, this kind
of surgery is referred to as endoscopic sinus surgery, or ESS.
Minimally invasive surgery is used when the bodys interior structures
can be reached with a surgical instrument through natural openings, such as
the nostrils, or when access to an interior structure requires only a small
incision on the bodys surface.
In image-guided surgery, images of the anatomy, such as computed tomography
scans (CT or CAT scans) are used in the operating room to guide the surgeon
during a procedure.
In ESS, small, narrow instruments are placed in the nostrils and passed through
the nose. The surgeon uses the endoscope to view the sinuses, and uses other
surgical instruments to remove diseased sinus tissue and to open blocked breathing
passages.
The endoscope acts like a miniature telescope to clearly illuminate the
surgeons view of the sinuses. Like a telescope, the endoscope provides
a detailed close-up view of the immediate surface area, but does not allow
the surgeon to see around corners, or to locate surgical instruments in relation
to the surrounding anatomy.
Although ESS is one of the most popular methods used today to correct
sinus problems, until recently, surgeons performing ESS depended only
on their skills,information provided by the Radiology Department, and
what could be seen through the endoscope.
About
Visualization Technology Inc.
The InstaTrak System was designed to make ESS a safer, more effective
procedure. Visualization Technology, Inc. (VTI) was established in 1993
to develop image-guided devices for medical and surgical use. The experienced,
dedicated team at VTI uses the latest methods in high technology research
and development to bring innovative products to this rapidly emerging
medical field.
Preparing
for your surgery the Radiology Department
Before going to the operating room, you will visit the Radiology Department.
While in Radiology, please follow the instructions of the staff. Their instructions
are crucial to gathering important information that your surgeon will use
during your procedure.
In Radiology, you will be asked to remove all metal objects that you
may be wearing on your head, such as jewelry or eyeglasses. You may wish to
remove these items before going to Radiology.
A technologist will place the InstaTrak System Headset on your head.
You will wear the Headset while the CT scans needed for your surgery are
taken. The Headset is designed to fit snugly on your head and across the
bridge of your nose, and has ear pieces that rest in your ear canal.
When your scans are complete, they will be stored in the InstaTrak System
computer. At the time of your surgery, the scans and the Headset will be brought
to the Operating Room.
The Operating
Room
You will be wearing a Headset for your CT scan and during your surgery. The
Headset automatically aligns your computerized CT images with your anatomy. Before
surgery begins, the surgical staff will reposition the Headset on your head,
and they will remove it when your surgery is complete.
For
more information
Your surgeon will be happy to answer any questions you may have about your
condition, treatment options, the surgical procedure, recovery and after
care.

Claims
and contraindications
The InstaTrak System was designed for use in the treatment of acute and
chronic sinusitis, endoscopic dacryocystorhinostomy, optic nerve and orbital
decompression, polyp removal, tumor biopsy and removal, and the repair of
CSF leaks, pituitary disorder, and encephalocele.
The InstaTrak System should not be used on patients who have electronic
devices that connect directly to the brain or nervous system.
