Kitaguchi Y, et al. - In this retrospective, observational, case-control study, researchers investigated the predictability of exophthalmos reduction in deep lateral orbital wall decompression for Graves’ orbitopathy by using a preoperative CT. Forty-three patients (43 orbits) treated with deep lateral decompression with (27 patients) and without removal of fat (16 patients). According to findings, positive predictors of exophthalmos reduction after deep lateral decompression were trigone width and amount of fat removed. Trigone width was inversely linked to orbital width, and outcomes demonstrated that larger reductions in exophthalmos in narrower orbits could be achieved. This method of prediction based on CT will assist with preoperative decision-making regarding additional fat removal and/or removal of another orbital wall.
