Correlation of retrobulbar volume change with resected orbital fat volume and XXXX for @entity6875 .

@entity1 @entity5768 @entity6875 @entity1560
PURPOSE: To evaluate the correlation of retrobulbar volume change, resected orbital fat volume, and @entity1560 . DESIGN: Cross-sectional and prospective study. METHODS: Twenty-two @entity1 (44 orbits) with @entity6875 underwent fatty decompression. Preoperative orbital computed tomography (CT) imaging with a 2-mm cut was compared with postoperative imaging carried out 6 months after fatty decompression. The relationship of retrobulbar volume change, resected orbital fat volume, and @entity5768 reduction was analyzed by Pearson correlation. Linear regression was performed using resected fat volume or @entity5768 reduction as independent variables and retrobulbar volume change as a dependent variable to validate the effect of fatty decompression. RESULTS: Mean @entity5768 reduction was 4.1    0.9 mm. Mean volume of resected orbital fat was 4.4    1.2 mL. Mean retrobulbar volume change in computed tomographic imaging was 3.2    1.0 cm(3). The change in retrobulbar volume was correlated strongly with @entity5768 reduction and volume of resected orbital fat. Linear regression revealed the following equation for Retrobulbar volume change: 0.546   Hertel change + 0.945 or 0.293   Volume of resected orbital fat + 1.917. CONCLUSIONS: Fatty decompression can reduce @entity5768 for @entity1 with disfiguring @entity6875 . Because of the close correlation of retrobulbar volume change with volume of resected orbital fat and @entity5768 reduction, we propose that orbital fat removal may be accompanied by @entity1560 . Evidence of decreased retrobulbar volume may result in effective @entity5768 reduction.
