PURPOSE: In Graves' disease a discrepancy between volume increase of the orbital soft tissues and fixed volume of the orbital cavity leads to exophthalmos. The patients do not only feel cosmetically disfigured, they often complain about more or less painful retroorbital pressure sensation or show symptoms of compressive optic neuropathy or corneal exposure because of a significant lid lag. To solve this problem, different orbital decompression techniques have been developed. This is to report about our results with a modified Dollinger technique for lateral orbital decompression. PATIENTS AND METHODS: A total of 27 patients aged 19-76 years (mean: 45.1 years) with Grave's ophthalmopathy were recorded who had undergone orbital decompression by a lateral approach between June 1999 and April 2003. The modified Dollinger technique was performed by deepening the osteotomy to the level of the sphenoid wing and by additional resection of intraconal fat. RESULTS: The reduction of exophthalmos achieved after decompressive surgery averaged 2.9 +/- 1.1 mm. Of the patients whose indication for orbital decompression was a compressive neuropathy, the visual acuity improved postoperatively for 3 lines. Of the 16 patients with preoperative retrobulbar pressure sensation, 12 had no complaints after the operation. Remarkably no significant impairment of the ocular motility resulted after surgery. CONCLUSIONS: Decompression of the orbit by the modified Dollinger technique is a safe and effective approach to reduce exophthalmos, retrobulbar pressure sensation, and compression neuropathy as a result of diffusely elevated orbital tissue tension. In the case of direct compression of the optic nerve in the orbital apex, additional medial orbital wall decompression has to be considered.
