To assess the quality of life (QoL) in a representative sample of patients with vestibular schwannoma and to ascertain the differences in outcomes associated with distinct management strategies. ⋯ The QoL within this patient cohort was extremely variable in each management group, mirroring the heterogeneous natural history of this disease process. QoL in patients with vestibular schwannoma cannot be predicted based on management strategy alone, but a poor QoL outcome is more likely in patients with larger, symptomatic tumors that are treated surgically.

Economic, cultural, and geographical reasons usually limit the access to specialized health centers in developing countries, especially in rural areas. Peruvian health system indicators still highlight significant unmet clinical need for neurosurgical patients. Our project is to develop the first highly specialized neurosurgical center in the EsSalud hospital of Trujillo, with the goal to improve the treatment of neurosurgical diseases in that region, thus optimizing their outcomes while decreasing expensive and risky patients transfer to the neurosurgical departments in the capital district. ⋯ An effective and adequate operative skill transfer to the local staff may be accomplished in a reasonable amount of time, thus guaranteeing a long-lasting improvement of neurosurgical care, while minimizing expenditures on personnel and capital. We believe that this is possible following a general microsurgical philosophy that can be simplified as follows: "simple, clean, fast, and preserving normal anatomy."

Surgical resection of a brain arteriovenous malformation (AVM) poses a technical challenge because of the fragility and number of small feeding and draining vessels around the nidus. Acquiring knowledge of the optimal force applied to such tissue is important in surgical performance and education. ⋯ Excessive force at the tool tip may result in injury to fragile vessels during AVM surgery. A quantifiable metric through force sensing instruments can detect and predict the occurrence of such injury. Such an instrument may be ideal for resident training and evaluation.

In patients with intracerebral hematoma (ICH), it is well known that brain atrophy occurs in the hemisphere ipsilateral to the hematoma. The present study aimed to investigate contralateral hemispheric volume changes in patients with ICH as well as related factors. ⋯ Contralateral parenchymal volumes were significantly decreased at the 3-month follow-up brain computed tomography scan. These findings may offer important clinical information on the remote brain injury of ICH.

Stereotactic biopsy is an everyday procedure implemented in numerous neurosurgical departments. The procedure is performed to obtain tumor tissue of unclear diagnosis. Going in hand with low complication rates and high diagnostic yield, stereotactic biopsies can be performed in adults and children likewise for histopathologic evaluation of lesions in eloquent localizations. However, little is known about whether aged patients do benefit from stereotactic biopsy or rather the therapy that is derived from histopathologic results. In this study, we therefore focused on old (80-84 years) and very old patients (85 years and older) to evaluate whether stereotactic biopsy should be performed leading to further therapy. We also assessed the complication rates of the procedure in this aged population. ⋯ Also in old and very old patients, a final histopathologic diagnosis should be established to provide adequate therapy. Our data show that most of these aged patients want to be treated.
