[Orbitopalpebral neurofibromatosis: orbital enlargement by an intracranial approach and palpebral correction].

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 the 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 orbito-palpebral neuro-fibromatosis.
