The use of a computer-assisted image-guided system (InstaTrak) in orbital surgery

Purpose; To assess the usefulness of a computer-assisted image-guided syste m (CAIGS) as an intraoperative anatomical guide in performing orbital surge ry. Methods: Noncomparative interventional case series of 30 consecutive orbita l procedures performed by one surgeon (J.G.C.) using the CAIGS (InstaTrak) for intraoperative anatomical guidance, Results: The series consisted of 8 cases of orbital decompression, 8 cases of orbital fracture, 11 cases of tumor excision, 2 cases of orbital reconst ruction for severe enophthalmos, and 1 case of drainage of an orbital absce ss. The CAIGS (InstaTrak) was useful in providing adjunctive intraoperative guidance in all 30 orbital cases. Conclusion: The CAIGS (InstaTrak) system is a useful adjunctive tool in pro viding intraoperative anatomic guidance in a consecutive series of varied o rbital operations.
