Craniofacial fibrous dysplasia and Ollier's disease: combined transfrontal and transfacial resection using the nasal-cheek flap.

: Fibrous dysplasia and Ollier's disease (skeletal chondromatosis) are bone lesions that result from disorders occurring during ossification. Here we report on a patient suffering from Ollier's disease in whom polyostotic fibrous dysplasia was detected. The main problem for this 20-year-old man was a nasoethmoidorbital cartilaginous mass causing nasal obstruction, nonreducible eye proptosis, and sleep apnea. The lesion was approached by means of a combined route, ie, transfrontally and transfacially (nasal-cheek flap). The possible pathogenetic links existing between the two lesions and the problems involved in surgical treatment are discussed.
