Symptomatic cranial fibrous dysplasias: clinico-radiological analysis in a series of eight operative cases with follow-up results.

Cranial fibrous dysplasias are rare and comprise less than one percent of all primary bone lesions. These painless progressively expanding destructive bone swellings produce cosmetic deformities (commonest), sino-orbital and auditive complications (less common), peripheral compressive cranial neuropathies (uncommon) and compressive central neurological manifestations (rarest). Until recently some of the primary dysplastic skull base lesions were either treated expectantly or excised incompletely.
