<p>It is known that there is an intraindividual amplitude variation in motor electroneurography when the same person is examined at different times. This variation affects the evaluation the status of the patient. The aim of this study was to investigate if the intraindividual amplitude variation decreased by photographing the electrode position, that later is used in the follow-up study. Twenty test persons were examined by four laboratory scientists. The nerves that were examined were median, ulnar, peroneal and tibial nerve. At the first examination the laboratory scientists used method guidelines and took photographs of the electrode position. The photographs were then used in the follow-up. The results showed that there was an indication of decreased of the intraindividual amplitude variation when photographic documentation was used instead of method guidelines.</p>

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. / 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.
