Coronal or swinging eyelid decompression for patients with disfiguring proptosis in Graves' orbitopathy? Comparison of results in one center.

Purpose: To compare 2 different approaches for 3-wall orbital decompression in patients with disfiguring proptosis due to Graves' orbitopathy, and to determine which technique is preferable.

Design: Retrospective nonrandomized study with a concurrent comparison group.

Participants: Charts of 74 consecutive patients with disfiguring proptosis due to Graves' orbitopathy who underwent coronal (46) or swinging eyelid (28) decompression between January 1, 2000 and January 1, 2004 were studied retrospectively.

Rectus extraocular muscle paths and decompression surgery for Graves orbitopathy: mechanism of motility disturbances.

Purpose: To study possible causes of motility disturbances that may result from orbital decompression surgery in patients with Graves orbitopathy and especially the role of rectus extraocular muscle paths.

Methods: Sixteen patients with Graves orbitopathy were studied before and 3 to 6 months after translid (6 patients) and coronal (10 patients) orbital decompression surgery for disfiguring proptosis. Ocular motility changes were measured by comparing maximum ductions and severity of diplopia, and the positions and the displacements of the anterior rectus muscle paths were objectively measured using cine magnetic resonance imaging (MRI).
