title: [Frontal osteoma with orbital extension. Apropos of a case].
abstract: Fronto ethmoidal osteoma are rare slow growth benign tumors. Exceptional ophthalmological and neurological complications can occur. The authors report a case of 32 years old man with eye compression by a giant frontal sinus osteoma. This lesion was responsible for a vertical diplopia and moderate proptosis. Plain skull X-Ray show a well defined opacity filling the whole left frontal sinus and C.T. scan delimited precisely orbital extension. Neurosurgical exposure enabled a complete extraction of the tumor and satisfying recovery. The authors have compared this case to those described in literature and insist on the importance of the pre-operative C.T. scan.
