Associations between Orbital Morphology and Exophthalmos Changes after Endoscopic Orbital Decompression to Treat Thyroid-related Orbitopathy

Purpose: To investigate orbital morphology parameters associated with exophthalmos changes in patients undergoing endoscopic decompression to treat thyroid-related orbitopathy.Methods: In total, 33 eyes of 18 orbitopathy who underwent were included this retrospective study. Data collected before and 6 months after surgery. We performed Hertel exophthalmometry derived from two-dimensional facial computed tomography records. Parameters reduction on univariate linear regression analysis subjected multivariate analyses.Results: Univariate showed that the preoperative length medial wall (β = 0.179, <i>p</i> 0.032) postoperative distance cone apex defect -0.139, 0.006) Multivariate these two was -0.118, 0.019).Conclusions: The reduction. orbitopathy, association should be considered when planning decompression.
