The intermedius nerve as a confounding variable for monitoring of the free-running electromyogram.

Objective: A-trains, a facial nerve EMG-pattern, are correlated with postoperative functional impairment. However, an unknown confounder is suspected to cause false positive monitoring results. The intermedius nerve contains motor fibers targeting lower facial muscles; their significance for facial nerve monitoring is yet unknown.

Treatment of aneurysmal subarachnoid haemorrhage in Germany: a nationwide analysis of the years 2005-2009.

Background: The aim of this study was to provide population-based nationwide rates of the different treatment modalities of aneurysmal subarachnoid haemorrhage (aSAH).

Methods: German Diagnosis-Related Group data of the years 2005-2009 were used to calculate hospitalisation rates for intracranial aneurysm with aSAH. This study includes over 83 million hospitalisations.

The relationship between nervus intermedius anatomy, ultrastructure, electrophysiology, and clinical function. Usefulness in cerebellopontine microsurgery.

Background: Although previous studies have described the clinical features of the nervus intermedius (NI), no attempt has yet been made to describe the relationship between the ultrastructural and electrophysiological characteristics of the nervus intermedius and its motor competence.

Objective: In this study, we analyzed the intraoperative electrophysiological response obtained during vestibular schwannoma surgery. The ultrastructure was studied using electron microscopy.

Neuroprotective efficacy of prophylactic enteral and parenteral nimodipine treatment in vestibular schwannoma surgery: a comparative study.

Unlabelled: BACKGROUND AND STUDY AIMS/OBJECT: Oral nimodipine improves neurologic outcome after aneurysmal subarachnoid hemorrhage. In addition, the neuroprotective efficacy of nimodipine has been revealed following skull base, laryngeal, and maxillofacial surgery. Pharmacokinetic investigations showed nimodipine to reach higher serum levels following parenteral versus enteral administration.

A-trains for intraoperative monitoring in patients with recurrent vestibular schwannoma.

Background: Second surgery of recurrent vestibular schwannoma (VS) after previous surgery, stereotactic radiosurgery (SR) or fractionated radiotherapy (FR) carries an increased risk for deterioration of facial nerve function, e.g., due to adhesions, underlining the need for intraoperative monitoring.
