To determine any differences in self-reported dysphagia in patients treated with single-level anterior cervical decompression with different zero-profile implants (arthroplasty vs. arthrodesis) and identify risk factors for postoperative dysphagia. ⋯ Postoperative dysphagia remains a common incidence, despite advances in instrumentation technologies. However, cervical disc arthroplasty is superior to anterior cervical discectomy and fusion in ameliorating the symptom of dysphagia in the early postoperative term. Heavy smoker, PSTS change (≥5 mm), and CA change (≥5 degrees) were important predictors of postoperative dysphagia.

Comparative Study
Intraoperative Hypotension during Second Stage of Deep Brain Stimulator Placement: Same Day versus Different day Procedures.
We evaluated blood pressure management associated with implantable pulse generator (IPG) procedure on same day (SD) versus different day (DD) from deep brain stimulation (DBS) placement. ⋯ No difference in intraoperative vasopressor use was found between SD versus DD IPG placement, but the SD group had a significantly lower minimum MAP.

Some patients suffer postoperative hearing loss even when the intraoperative auditory brainstem response (ABR) is preserved during vestibular schwannomas surgery. This study was conducted to evaluate whether there are dynamic changes of the ABR after surgery. ⋯ The study identifies ongoing changes of ABR quality and hearing function after the end of vestibular schwannoma surgery. Therefore it seems worthwhile to continue ABR monitoring in the postoperative phase in order to identify patients who are at risk of a secondary hearing deterioration and start therapeutic interventions in a timely manner.

Recent prospective multicenter studies have shown that the probability of rupture of unruptured aneurysms with maximal diameter <7 mm is rather low. However, the overall risks and long-term impact of unruptured aneurysms on lifetime quality of life are still unknown. ⋯ Lifetime effects of small unruptured aneurysms without risk factors increasing the probability of rupture are relatively small, and most patients were expected to die of diseases other than subarachnoid hemorrhage.

Precisely defining complications, which are used to measure overall quality, is necessary for critical review of delivery of care and quality improvement in endovascular neurosurgery, which lacks common definitions for complications. Furthermore, in endovascular interventions, events that may be labeled complications may not always negatively affect outcome. Our objective is to provide precise definitions for quality evaluation within endovascular neurosurgery. Thus, we propose an endovascular-specific classification system of complications based on our own patient series. ⋯ We propose an endovascular-specific classification system of complications with 4 categories: mechanical, technical, judgment errors, and critical events. This system provides a framework for future studies and quality control in endovascular neurosurgery.
