Intracranial enlargement of the orbital cavity and palpebral remodeling for orbitopalpebral neurofibromatosis.

Exophthalmos with lowering of the globe, eyelid enlargement, and canthal displacement are the usual consequences of orbitopalpebral neurofibromatosis. A cerebral hernia into the orbit may be seen on CT scan. An intracranial approach allows for pushing back the brain with a bone graft to create an enlarged orbital cavity, lifting the globe with a graft on the orbital floor, and fixing the canthi in proper position. An eyelid radical resection is performed in the same stage or later. This approach is discussed in the treatment of 17 cases of orbitopalpebral neurofibromatosis.
