RESUMO
We reviewed 17 cases with dysthyroid exophthalmos in 13 patients which were treated with antral-ethmoidal decompression surgery. Transantral approaches were done in 6 orbits of 3 patients and transfornix approaches were done in 11 orbits of 10 patients. The amount of postoperative retroplacement of the globe was 4.3mm in average and ranged from 1mm to 9mm during the average follow-up period of 14.9 months. All patients with compressive optic neuropathy improved in visual acuity by 3 or 4 lines of Hahn test chart. In most patients the restriction of ocular motility was improved and exposure keratitis decreased The cosmetic results were also satisfactory. The postoperative complications were induced diplopia in 2 cases and permanent infraorbital anesthesia in 1 case. The detailed surgical procedures and results were presented and reviewed.
