ObjectivesSkull 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 observe the SF enhancement of skull base meningiomas.Patients and methodsA prospective, within-subjects study was designed and performed. This study included twelve patients with skull base meningiomas. After an initial dissection, digital pictures were taken before and after systematic injections of SF using the same light-source used for the surgical microscope. These pictures were analyzed with software that calculated the wavelengths of the sodium fluorescein before and after the injection of the dye.ResultsThe meningiomas in the sample included the following types: 1 cavernous sinus, 1 olfactory groove, 3 petroclival, 1 tuberculum sellae, 3 sphenoid wings, 1 anterior clinoid, and 2 temporal floor. The SF enhancement in all tumors was strongly positive.ConclusionsThe low cost, universal availability and safety of SF indicate that this dye should be examined in further studies, and its applications in skull-base meningioma surgeries should be further assessed.
