Functional and esthetic outcome after bony lateral wall decompression with orbital rim removal and additional fat resection in graves' orbitopathy with regard to the configuration of the lateral canthal region.

AbstractPurpose: To investigate whether en bloc resection of the lateral orbital wall, including the orbital rim, during lateral wall decompression surgery in patients with Graves’ orbitopathy (GO) potentially influences the esthetic and functional aspects of the lateral canthal region.Methods: Lateral wall decompression was performed in 30 orbits of 18 patients using an upper lidcrease approach involving complete removal of the lateral orbital wall combined with additional orbital fat resection. Patients undergoing surgery before January 2010 were evaluated retrospectively for exophthalmos, vertical lid aperture, lagophthalmos and eye motility. Patients undergoing surgery after January 2010 were evaluated prospectively in addition for horizontal lid aperture, pupillary distance, lateral movement of the lateral canthus, and the disease-specific GO-QOL questionnaire, including subjective and objective assessments of the appearance of the lateral canthal region.Results: A mean exophthalmos reduction of 3.0 ...
