Gliederung

Text

Objective: Facial palsy is a debilitating complication after surgery of cerebello-pontine angle (CPA) tumors. Recently, a surgical suction device coupled with a monopolar stimulator ("stimulation-suction") was introduced for glioma surgery. It allowed cortico-spinal tract identification and resulted in better clinical and radiological outcomes. We sought to evaluate the usefulness of this tool for CPA surgery, especially for continuous and dynamic facial nerve mapping.

Methods: Patients operated with the stimulation-suction for a CPA tumor between 04/ 2016 and 05/ 2017 were identified. Clinical charts, including operating reports, neuromonitoring reports, and imaging data were evaluated. Patients operated without the stimulation-suction, having a non-CPA tumor or with incomplete data sets were excluded.

Results: The studied population comprised 17 patients (6 females and 11 males). The age ranged from 2 to 77 years (mean age 45.7 years, SEM: 22.7 years). Most CPA tumors were large (> 30mm) vestibular schwannomas (n=10); other pathologies were: petrous meningioma (n=1), metastasis (n=1), medullo-blastoma (n=2), ependymoma (n=2), pilocytic astrocytoma (n=1). The stimulation-suction allowed for early identification of the facial nerve, handling and ergonomy were rated excellent and workflow improved. No complication due to utilization of the stimulation-suction was encountered. Clinical and radiological outcome compared favorably to institutional experience and the literature.

Conclusion: Up to now, "nerve damage" served as surrogate for "nerve function". This concept should be challenged. The studied stimulation-suction detected the facial nerve far earlier than conventional techniques. A larger, prospective study is warranted to better assess improvements in outcome.
