Image-guided endoscopic orbital decompression for Graves' orbitopathy.
OBJECTIVE
We studied the efficacy and safety of image-guided balanced orbital decompression for Graves' orbitopathy.


METHODS
The data of 24 patients (45 orbits) were reviewed for demographics, ophthalmologic outcomes, and complications in regard to image-guided (18 orbits) versus non-image-guided surgery (27 orbits).


RESULTS
Overall, all patients had a reduction in proptosis (mean reduction, 6.2 mm in proptosis) as measured by Hertel exophthalmometry. There was improvement in the visual acuity of all 12 orbits with preoperative acuity of 20/40 or worse and either complete resolution (38%) or improvement (62%) in the 16 orbits with optic neuropathy. These measures reached statistical significance. Despite subjective improvement in surgeon confidence, the use of image guidance did not result in a statistically significant difference in postoperative ophthalmologic outcomes. Medical and sinonasal complications were experienced by 11.1% and 18.5% of patients who underwent image-guided and non-image-guided orbital decompression, respectively.


CONCLUSIONS
Image guidance may be a useful adjunct to balanced orbital decompression for Graves' orbitopathy, but it was not associated with a statistically significant improvement in outcomes in this study.
