Miniplate reconstruction of the lateral orbital rim after orbital decompression for Graves disease.
BACKGROUND
Removal of lateral orbital bone with or without simultaneous removal of the lateral orbital rim is an accepted method of orbital decompression for Graves disease. Once removed, the bone is no longer available for reconstruction and secondary complications such as rounding of the canthal angle, canthal dystopia, and globe dystopia may result.


METHODS
The authors replaced the excised bone with a titanium miniplate to protect the globe and fixate the lateral canthal tendon in 18 patients (33 orbits). The orbital rim and lateral orbital wall were completely removed, and the inner aspect of the orbit was enlarged with a cutting burr. A standard titanium miniplate was then anchored to remaining bone, and soft tissue was secured to the miniplate to reconstruct the lateral canthus.


RESULTS
The results, as manifest by appearance of the lateral canthus and position of the eyelid in apposition to the globe, were graded as excellent in all patients and orbits. There were no early or late complications.


CONCLUSIONS
Miniplate reconstruction of the lateral orbital rim after decompression for Graves disease allows the beneficial affect of lateral decompression and preserves the functional aspect of the lateral orbital wall.
