Background: Traditionally, supratentorial craniotomy has been used to sever tuberculum sellae meningiomas (TSMs), but there has been a remarkably increasing tendency of extended endoscopic endonasal approach (EEEA) used to treat TSMs in the recent decade. Several documents have described the advantages and disadvantages of both approaches, but there is no consensus on whether one is superior to the other.
Objective: This study aimed to compare surgical outcomes between craniotomy and EEEA for TSMS treated at our institution.
Object: Although revision surgery for recurrent craniopharyngiomas is more challenging than primary surgery and often accompanies a higher risk of death and complications, endoscopic endonasal transsphenoidal surgery (EETS) is sometimes still an effective and reliable treatment option. In this study, we introduced the surgical outcomes of EETS for recurrent craniopharyngiomas and summarized the surgical experiences.
Methods: Between 2014 and 2018, 28 patients with recurrent craniopharyngiomas underwent 29 EETS in our department.

Objective: To assess the clinical value of transcranial Doppler(TCD) ultrasonography in diagnosing brain death in patients with severe craniocerebral injury.
Methods: Forty patients of severe craniocerebral injury defined by a scene Glasgow coma scale(GCS)≤8, admitted to Department of Neurosurgery of First Central Clinical Hospital of Tianjin Medical University, were divided into two groups based upon the prognosis: the death group(n=15) and the survival group (n=25). All patients were examined dynamically by TCD, and the occurrence of retrograde diastolic flow (RDF) and mean velocity (Vm) of middle cerebral arteries (MCA) were measured as well as the pulse index (PI).
