OBJECTIVES Skull base meningiomas are a neurosurgical challenge due to the involvement of neurovascular structures. In this study, the authors present the first study of the trans-operative use of sodium fluorescein (SF) to enhance skull base meningiomas and perform a quantitative digital analysis of the tumors' pigmentation. The goal of the study was to(More)
OBJECTIVE The authors present this study using sodium fluorescein (SF) to enhance skull base tumors by performing a quantitative digital analysis of tumor enhancement. The purpose of this study is to observe the grade of SF enhancement by the tumors. METHODS A prospective experiment within-subjects study design was performed which included six patients(More)
BACKGROUND The resection of the meningiomas surrounding the dura is an important goal during the removal of a convexity meningioma. The authors present the first application of sodium fluorescein (SF) as a tool for tumor and dural tail identification in convexity meningiomas. METHODS Five frontal convexity meningiomas operated on between December 2012 and(More)
Objective The identification of cranial nerves is one of the most challenging goals in the dissection of skull base meningiomas. The authors present an application of sodium fluorescein (SF) in skull base meningiomas with the purpose of improving the identification of cranial nerves. Design A prospective study within-subjects design. Setting Hospital(More)
OBJECTIVES The aim of this study was to verify the promoting effect of carbamide peroxide on dimethylbenzanthracene (DMBA)-induced carcinogenesis in the hamster buccal pouch, in order to reduce the period of latency for tumor formation. METHODS Sixteen hamsters were randomized into two groups of eight animals each. The hamsters of the group I had their(More)
Peripheral nerve trauma results in functional loss in the innervated organ, and recovery without surgical intervention is rare. Many surgical techniques can be used for nerve repair. Among these, the tubulization technique can be highlighted: this allows regenerative factors to be introduced into the chamber. Cell therapy and tissue engineering have arisen(More)
