title: Orbitocranial asymmetry.
abstract: Eleven cases are chosen to illustrate the differential diagnosis of deforming lesions of the bony orbit and its vicinity, which cause unilateral proptosis or other cranio-facial disfigurement. Three distinct varieties of orbito-cranial neurofibromatosis are distinguished, and they are contrasted with other deforming lesions of childhood--unilateral craniosynostosis, chronic juvenile subdural hygroma of the temporal fossa and congenital facial hemihypertrophy. Adult lesions are represented by intrinisic tumours of the orbit and paranasal sinuses, and by the commonest two processes deforming the sphenoid bone, meningioma and osseous fibrous dysplasia.
