title: Ethmoidectomy decompression for the treatment of Graves' optic neuropathy.
abstract: When orbital decompression becomes necessary in Graves' optic neuropathy, medial wall decompression is a necessary component of the decompression procedure. The ethmoidectomy approach allows more direct visualization of the posterior ethmoids and sphenoids to effect maximum decompression. This is particularly important in cases in which computed tomography shows the medial rectus muscle to be enlarged posteriorly in the orbit. The procedure provides excellent visualization of the medial rectus. As with any medial wall decompression procedure, postoperative restriction of horizontal motility is a frequent complication, often necessitating more than one subsequent operation. The authors describe their experience with the procedure in 25 patients with Graves' optic neuropathy.
