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

Ophthalmic Plast Reconstr Surg. 2001 Nov;17(6):447-51. doi: 10.1097/00002341-200111000-00012.


Purpose: To assess the usefulness of a computer-assisted image-guided system (CAIGS) as an intraoperative anatomical guide in performing orbital surgery.

Methods: Noncomparative interventional case series of 30 consecutive orbital 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 reconstruction for severe enophthalmos, and 1 case of drainage of an orbital abscess. 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 providing intraoperative anatomic guidance in a consecutive series of varied orbital operations.
