Abstract

The aim of this study was to compare the surgical outcomes of deep lateral orbital decompression using the rim-sparing technique versus the rim-removal technique in Graves' orbitopathy (GO). A retrospective cohort study of 75 orbits in 50 patients with GO was performed. Proptosis, best corrected visual acuity (BCVA), intraocular pressure (IOP), upper and lower lid margin to reflex distances (MRD-1 and MRD-2, respectively), diplopia, ocular restriction, and GO quality of life (GO-QOL) questionnaire results were analyzed pre- and postoperatively. The average proptosis reduction ranged from 3.5 mm to 6.7 mm with the rim-sparing technique and from 3.6 mm to 6.7 mm with the rim-removal technique (P > 0.05). All orbits with dysthyroid optic neuropathy in the rim-sparing group and 87.5% of such orbits in the rim-removal group showed improved BCVA (P = 0.321). Reductions in IOP, MRD-1, and MRD-2 were observed with both techniques. Patients in the rim-sparing group had greater improvements in GO-QOL appearance score (P = 0.043). In conclusion, rim-sparing orbital decompression provides efficacious outcomes with greater improvements in patient quality of life than the rim-removal technique. The rim-sparing technique should be considered as a preferable option because it preserves the integrity of the lateral vertical maxillary buttress and bony protection for the orbital contents.
