ReviewChronological characterization of hearing preservation after radiosurgery for vestibular schwannoma: a comprehensive meta-analysis.
Hearing outcomes following Gamma Knife radiosurgery (GKRS) for vestibular schwannoma (VS) are multifactorial and poorly characterized in prior literature. In this study the authors evaluated hearing outcomes chronologically to identify prognostic factors of serviceable hearing preservation (HP) rates following GKRS for VS. ⋯ This meta-analysis identifies age and radiation dose as independent prognostic factors for HP. Age-related hearing deterioration appears to be concentrated in the first 5 years after GKRS, whereas radiation dose was associated with HP at last follow-up, between 5 and < 10 years, and at ≥ 10 years after radiosurgery. This meta-analysis offers an objective overview of the literature and a framework for clinical decision-making, with applications for treatment planning and patient counseling.

Role of the endonasal endoscopic approach in intraorbital tumor surgery: insights from a single-center experience.
This study aimed to evaluate the effectiveness of the endoscopic endonasal approach (EEA) in the surgical management of intraorbital tumors and analyze the adjunctive role of the transorbital approach (TOA) and extended modified medial maxillectomy (EMMM) in addressing anatomically complex tumors. ⋯ The combination of EEA with TOA and EMMM provides a comprehensive and adaptable surgical strategy for intraorbital tumors, accommodating various lesion locations and complexities. This combined approach not only facilitates extensive tumor resection but also maximizes the preservation of ocular function and cosmetic outcomes. The favorable results of this study support the use of a multidisciplinary surgical approach and highlight the potential for improved patient outcomes with the continued development of endoscopic techniques. Further research with a larger cohort is essential to validate these findings and establish guidelines for the combined use of these surgical methods.

Impact of preoperative nutritional status on morbidity and mortality in elderly patients undergoing subdural hematoma evacuation: the role of the Geriatric Nutritional Risk Index.
Nutritional status has been shown to impact patient outcomes across several neurosurgical procedures. However, few prior studies have assessed associations between preoperative nutritional status and outcomes in elderly patients undergoing subdural hematoma evacuations. The aim of this study was to identify associations between preoperative nutritional status and short-term outcomes in patients aged 65 years and older undergoing subdural hematoma evacuation. ⋯ The authors' findings suggest that preoperative nutritional status may have implications for short-term outcomes after subdural hematoma evacuation in patients aged 65 years and older. Further studies are necessary to better optimize nutritional status perioperatively in this patient population.

Minimum cochlear dose impacts hearing after radiosurgery for sporadic vestibular schwannoma.
It is uncertain which cochlear dose parameters significantly impact hearing after stereotactic radiosurgery (SRS) for sporadic vestibular schwannoma (VS). The objective of this study was to determine the impact of cochlear dose parameters on hearing outcomes for patients with serviceable hearing (SH). ⋯ The minimum cochlear dose impacts hearing outcomes after SRS for VS and should be considered in radiosurgical treatment planning. In this cohort, the mean cochlear dose was only associated with hearing outcomes in the subgroup of patients with class B hearing at SRS.

Neurosurgery in Australia's Top End: the lifesaving advantages of developing sustainable neurosurgical care in rural and remote regions.
The authors' goal was to perform a retrospective audit of all emergency cranial neurosurgery performed at the Royal Darwin Hospital in the first 5 years of the unit and to compile their data in a similar fashion to an earlier study titled "Emergency Neurosurgery in Darwin: Still the Generalist Surgeons' Responsibility," which was published in 2015. ⋯ The data illustrate the importance of developing small but sustainable neurosurgical units in rural and remote areas. A dedicated neurosurgical unit at the Royal Darwin Hospital has led to an increase in the amount and variety of emergency neurosurgery performed in Darwin. Interstate transfers have reduced. This has tangible lifesaving and economic advantages.
