T1  - Significance of the electrophysiological facial nerve monitoring during acoustic neuroma surgery: postoperative long-term results
N2  - Bei der Operation eines Akustikusneurinoms kann es zu einer Schädigung von Hirnnerven kommen. Unter anderem kann die Funktion des Nervus facialis postoperativ vermindert sein. Um nachteilige Effekte durch eine Facialisstörung zu verhindern wurde das intraoperative elektrophysiologische Monitoring des Nervus facialis eingeführt. Ein Vergleich von Daten aus vorangegangenen Artikeln, bei denen Patienten ohne intraoperatives Monitoring behandelt worden waren, mit Werten des Patientengutes der Universitätsklinik Würzburg zwischen 1998-2003, zeigte einen deutlichen Vorteil für diejenigen Patienten, die während der Operation eine Überwachung des Nervus facialis erfuhren.
N2  - Operating on acoustic neuromas can lead to serious impairment of cranial nerves including the facial nerve whose function can be postoperatively reduced. Therefore, intraoperative electropysiological nerve monitoring has been established in order to avoid negative effects on the facial nerve during operation. Comparing historic data where the adjunct of intraoperative monitoring had not been used with data from the Universitätsklinik Würzburg (from patients who had been operated between 1998-2003 with intraoperative monitoring), an obvious benefit was being proved for those who had been operated on with monitoring.

T1  - Application of intentional facial nerve stimulation during cochlear implantation as an electrophysiological tool to estimate the intracochlear electrode position
JF  - Scientific Reports
N2  - This proof of concept describes the use of evoked electromyographic (EMG) activation of the facial nerve for intraoperative monitoring of the electrode insertion during cochlear implantation (CI). Intraoperative EMG measurements from the facial nerve were conducted in nine patients undergoing CI implantation. Electric current pulses were emitted from contacts on the CI array during and immediately after electrode insertion. For control, the results of EMG measurements were compared to postoperative flat panel volume computed tomography scans with secondary reconstruction (fpVCT\(_{SECO}\)). During insertion, the EMG response evoked by the electrical stimulation from the CI was growing with the stimulating contact approaching the facial nerve and declined with increasing distance. After full insertion, contacts on the apical half of the CI array stimulated higher EMG responses compared with those on the basal half. Comparison with postoperative imaging demonstrated that electrode contacts stimulating high EMG responses had the shortest distances to the facial nerve. It could be demonstrated that electrically evoked EMG activation of the facial nerve can be used to monitor the progress during CI electrode insertion and to control the intracochlear electrode position after full insertion.
