Orbital decompression for Graves' ophthalmopathy by inferomedial, by inferomedial plus lateral, and by coronal approach.
To test the efficacy and safety of orbital decompression for Graves' ophthalmopathy, the authors studied the records of 60 consecutive patients who were operated on for dysthyroid optic neuropathy or for rehabilitative purposes. Patients decompressed for neuropathy were older, had less proptosis, and a shorter duration of eye disease than patients operated on for disfigurement. The authors compared the results of three surgical procedures including the inferomedial, the inferomedial plus lateral, and the coronal approach. Regarding improvement of visual function, no difference was found between the three techniques. Patients in whom vision failed to recover had a high prevalence of diabetes mellitus. Proptosis reduction varied from 1 to 9 mm, depending on the number of walls decompressed. There was no net change in the prevalence of diplopia. Persistent complications were seen in less than 5% of all decompressions. The authors conclude that orbital decompression for Graves' ophthalmopathy is safe and efficacious, regardless of surgical procedure. However, the coronal approach gives the best cosmetic results.
