Endoscopic and Transconjunctival Orbital Decompression for Thyroid‐Related Orbital Apex Compression

Abstract

The study supports the treatment of thyroid-related orbital apex compression with and without compressive optic neuropathy by a combined transconjunctival and endoscopic approach. This approach offers short hospital stays, excellent visual recovery, and minimal complications in patients with thyroid-related orbital apex compressive myopathy and related compressive optic neuropathy. The beneficial effects observed in the patients with visual loss continued to improve over time and were significant (P <.001).

En bloc resection of the lateral orbital rim to reduce exophthalmos in patients with Graves' disease

“…Other studies have described new computer-assisted orbital decompression methods to improve the accuracy of the bony resection, leading to better symmetry (Marecaux et al, 2006). The transconjunctional approach with lateral canthal extension (Barkhuysen et al, 2009) or in combination with an endoscopic approach (Schaefer et al, 2003) has also been described with the benefit of an inconspicuous scarring.…”

Surgery for graves' ophthalmopathy: When and what for? The experience of Iasi

“…Other authors (21) consider that decompression through intervention on orbit walls only is more efficient on the reduction of the degree of exophthalmos, but it has minimal effects on the correction of diplopia. This type of intervention seems even to be followed by an increased postoperatory rate of appearance or aggravation of diplopia, irrespective of the surgical techniquetransantral (9) or endoscopical (29). Postoperatory evolution of diplopia is however a question of debate, since final results vary greatly from surgical teams using the same surgery technique.…”

A Cadaveric Study of the Morphometric and Geometric Relationships of the Orbital Apex

“…The degree to which the orbit can be decompressed by removing segments of the orbital wall necessitates the need to be aware of the proximity of operating margins to the optic canal. Compressive optic neuropathy is reported to occur in up to 9% of patients with thyroid related orbitopathy (Schaefer et al, 2003). Compression commonly occurs due to oedema of the extraocular muscles, which compress the optic nerve.…”
