C-modified osteotomy for bilateral advancement of the orbital rim in Graves orbitopathy: a technical note

Int J Oral Maxillofac Surg. 2008 Sep;37(9):853-7. doi: 10.1016/j.ijom.2008.05.012. Epub 2008 Jul 7.

Abstract

The authors present a modification of the classical three-wall orbital decompression for the treatment of Graves' orbitopathy. It consists of two 'C' osteotomies for the bilateral projection of the superolateral, lateral and inferolateral orbital rims, associated with the removal of the lateral orbital walls. This technique is performed following a coronal approach. Ultrasound cutting instruments were used for the osteotomies. They avoided lesion of surrounding soft tissues, such as the duramater and the periorbital tissues. Stabilization of the advanced structure was achieved by interposition of autologous bone graft obtained from the outer cortex of the calvaria. An extreme advancement of the orbital rim with resolution of diplopia, ocular pain and eyelid incompetence was obtained. Using this procedure, a good functional and aesthetic outcome was achieved.
