Multicenter Study
Long-term Auditory Symptoms in Patients With Sporadic Vestibular Schwannoma: An International Cross-Sectional Study.
There are limited data on the long-term auditory symptoms in patients with sporadic small- and medium-sized vestibular schwannoma (VS). The initial treatment strategy for VS is controversial. ⋯ The overall prognosis for hearing in sporadic VS is poor regardless of treatment strategy. Treatment modality was an independent predictor of hearing status; observation was associated with the highest rate of hearing preservation. .

Better ways to predict motor outcome following hemispherectomy are necessary to implement the informed consent process in patients with hemispheric epilepsy. The volumetric analysis of cerebral peduncles and cerebellar hemispheres in patients who had undergone hemispherectomy may determine prognostic implications for postoperative hemiparesis. ⋯ While patients who undergo hemispherectomy are heterogeneous, we report a method of predicting postoperative hemiparesis only using a standard volumetric MRI. This information could be used in the preoperative discussions with patients and families to help better understand that chance of retaining baseline motor function.

The use of administrative billing data may enable large-scale assessments of treatment outcomes for Chiari Malformation type I (CM-1). However, to utilize such data sets, validated International Classification of Diseases, Ninth Revision (ICD-9-CM) code algorithms for identifying CM-1 surgery are needed. ⋯ ICD-9-CM code Algorithm 2 has excellent PPV and good sensitivity to identify adult CM-1 decompression surgery. These results lay the foundation for studying CM-1 treatment outcomes by using large administrative databases.

Comparative Study
Comparison of Stent-Assisted Coiling vs Coiling Alone in 563 Intracranial Aneurysms: Safety and Efficacy at a High-Volume Center.
Stent-assisted coiling has been used in both unruptured and ruptured aneurysms, but the safety and efficacy still remain controversial. ⋯ Compared with coiling alone, stent-assisted coiling may achieve lower recurrence rates, with comparable procedure-related complications and clinical outcomes in both ruptured and unruptured aneurysms.
