Graves’ disease, an autoimmune disorder that consists of hyperthyroidism, goiter, and exophthalmos, is the most common cause of hyperthyroidism (incidence 5 in 10,000). More women are afflicted, but men show more severe orbit-opathy. Immunoglobins activate thyrotropin receptors causing thyromegaly and thyroxin release. Antibody-mediated infiltrates thicken the orbital tissues, but uniquely spare the lateral rectus muscle (Figure 1A). Only 6% of Graves’ patients have clinical thyroid eye disease (TED). As orbital volumes expand, globes become proptotic and eyelids cannot fully close (Figure 1B). The resultant exposure keratitis causes painful irritation and redness. Optic nerve compression and diplopia from muscle fibrosis may further deteriorate vision, culminating in blindness. Although the mechanism is unclear, radioactive iodine ablation therapy and smoking significantly accelerate the development and progression of TED. Medical therapy aims to control orbital inflammation. Oral steroids benefit acutely, but fail to halt overall progression. External-beam radiation (XRT) may improve the acute inflammation but potentiates long-term fibrosis. The modest benefit of XRT has the high cost of long-term dry eye keratitis and premature cataracts. Orbital decompression, the surgical removal of the orbital walls, displaces the orbital girth and relieves the pressure on the globe, thus resolving the proptosis. By performing equal
Orbital Decompression for Thyroid Eye Disease
(A) Coronal CT of a patient s/p left orbital decompression. Inferior and medial rectus hypertrophy (*) is present as is com-‐pression of the right optic nerve (arrow). The left apex is more relaxed as the orbital contents displace into the temporal fossa and sinuses (arrowheads). (B) Axial CT shows severe TED. The entire globe is anterior to a dashed line drawn from the lateral canthus to the lacrimal crest. This extreme proptosis causes
decompression of the medial and lateral orbital walls, the globe remains centered and does not list (e.g. eso- or exo-tropia). Therefore, balanced orbital decompression maximally relieves proptosis while minimizing diplopia. CASE REPORT A 24 year-old transmission mechanic found it impossible to work because of a new tremor, blurry vision, and heat intolerance. He was diagnosed with Graves’ disease and his hyperthyroidism was effectively controlled with methimazole. His vision, however, continued to deteriorate and his eyes were red and painful. Exam revealed severe scleral injection and proptosis (Hertel = 28 mm). CT confirmed no orbital masses (Figure 2A). He underwent bilateral balanced orbital decompression. The lateral and inferior walls were removed via concealed transconjunctival and lateral canthotomy incisons. Concur-rently, an endoscopic endonasal approach allowed the medial wall and strut to be removed. The lateral orbital rims were advanced anteriorly and secured with bone grafts, thus moving the lateral canthus forward and optimizing lid closure. Stereotactic image-guidance surgical navigation safely allowed for maximum decompression of the orbital walls to the skull base and orbital apex. He had a succesful resultant decompression (Figure 2B). His eye pain and irritation resolved, and his vision and proptosis improved dramatically (Hertel = 17 mm) with an 11

The entire globe is anterior to the orbital plane: a line from the lateral canthus to the lacrimal crest. This extreme proptosis causes stretching of the optic nerve (arrow) and exposure keratitis.

Because of this, the proptosis has resolved and the equator of the globe is now posterior to the orbital plane.

Patients with tuberculum sellae meningiomas (TSM) often present with subtle, progressive visual deterioration. These tumors expand the suprasellar space displacing the optic nerves and chiasm; optic canal extension is frequent. TSM typically demonstrate homogenous contrast enhancement, normal sellar dimensions, and dural tails on MRI differentiating them from pituitary adenomas.
Conventional pterional, bifrontal, or orbito-zygomatic crani-otomy requires frontal and temporal lobe retraction, extensive subarachnoid dissection, and facial disassembly. Modern techniques can resolve these shortcomings. The endoscopic endonasal approach (EEA) provides a transnasal corridor obviating brain retraction, neural manipulation, and facial osteotomies. Alternatively, the focused orbito-zygomatic keyhole craniotomy (FOZA) with extradural dissection, a technique developed at the Skull Base Center, provides direct extradural access to the tumor minimizing brain and optic nerve manipulation. The position of the optic nerve defines the appropriate approach.
This report describes two cases that illustrate our modern approach to the treatment of TSM at the Skull Base Center at Baylor University Medical Center at Dallas.
Patient 1: A 41 year-old woman presented with a 1-year history of visual deterioration and a bitemporal visual field deficit. MRI (Figure 1) revealed a sellar and suprasellar mass that enhanced homogenously. The 2.6 cm tumor displaced the infundibulum dorsally and the optic nerve laterally, and extended along a hyperostotic planum sphenoidale.
Because the TSM was medial to the optic nerves, the patient underwent an EEA. Complete tumor excision (Simpson Grade I) was achieved without optic nerve or brain traction. A vas-cularized nasoseptal flap reconstructed the skull base. The patient was discharged on POD#6 and pathology revealed a WHO Grade I meningioma. The patient had total visual recov-ery and normal hormonal function. At 1-year follow-up, there was no evidence of recurrent disease (Figure 2).
Patient 2: A 53 year-old woman presented with similar visual field deficits and headache. MRI again revealed a 2.5 cm enhancing sellar/suprasellar mass. However, this tumor extended lateral to the right optic canal (Figure 3), and would be difficult to remove endonasally without undue nerve traction.
