[Meningioma of the floor of the temporal fossa. Anatomo-clinical study of 11 cases].
The authors present eleven cases of middle fossa floor meningiomas. They describe the anatomical and clinical features of these tumors in this rare localisation. They emphasize the strait anatomical relations with the cranial base, eight cases were inserted above the superior surface of the petrous bone, two above the endocranial face of the horizontal part of the greater sphenoid wing, one above the horizontal part of the temporal squama. Headache (6 cases) and memory loss (4 cases) are the most frequent clinical feature, seizures (2 cases) and neuropsychologic troubles were probably undervalued. Auditory signs were present in three cases. There was no visual defect and cranial nerve impairment. They insist on the necessity to obtain a complete preoperative temporal bone CT scan exploration. They think that a well advised surgical act is sufficient for these meningiomas inserted above weak structures and with good prognosis: there's no recurrence in this study with a follow up from 12 to 132 months.
