We sought to describe complications after resection for meningioma with the use of longitudinal administrative data, which our group has shown recently to be superior to nonlongitudinal administrative data. ⋯ In this study, we report complication rates in patients undergoing resection for meningioma. Because of the longitudinal nature of the MarketScan database, we were able to capture a wide array of specific postoperative complications associated with meningioma resection procedures. Care should be taken in the selection of candidates for meningioma resection.

The middle fossa (MF) approach is one of the treatment options for patients with intracanalicular vestibular schwannomas. This study investigated whether enlargement of the internal auditory canal (IAC) represents a risk factor for hearing loss in the MF approach. ⋯ Enlargement of the IAC on coronal reconstruction computed tomography scan before surgery can predict hearing preservation using the MF approach. Patients without IE may represent good surgical candidates for the MF approach.

Comparative Study
G protein-coupled estrogen receptor levels after peripheral nerve injury in an experimental rat model.
To assess whether G protein-coupled estrogen receptor (GPER) levels were altered during crush-induced peripheral nerve injury in an experimental rat model. ⋯ Our results demonstrate that a basal level of GPER expression occurs in peripheral nerve tissue. The lowest level was detected 1 hour after crush injury, and the highest levels of GPER were detected 12 hours and 24 hours after trauma. Further trials on larger series are required to elucidate the role of GPER in terms of protection and treatment after nerve injury.

The Sylvian fissure has been dissected through the frontal side of the superficial Sylvian veins with sacrifice of the tributaries of the frontal superficial Sylvian vein, which may lead to venous infarction. In addition, disturbed venous drainage makes the brain susceptible to brain retraction. Therefore, preservation of the vein is essential in modern neurosurgery to decrease morbidity. ⋯ Keeping the proper dissection plane ("microvascular Sylvian fissure") is crucial to preserve the veins. The "paperknife technique" makes the division of the frontal and temporal lobe easier. The "denude technique" provides a wider space between the frontal lobe and the skull base. These techniques make it possible to obtain a sufficiently wide surgical corridor to the basal cistern without sacrificing the veins and their tributaries.
