Case Reports Comparative Study
Three-dimensional cortical surface reconstruction versus operative findings: their similarity and applications.
Three-dimensional cortical surface reconstruction (3DCSR) is an important tool for operations involving cerebral cortex, but data on its similarity to actual cortical architecture are lacking. In this study, the authors systematically tested the similarity between operative findings and 3DCSR built by a neuronavigation system and illustrated its applications. ⋯ Authors have systematically demonstrated that 3DCSR built by neuronavigation system in this study provides detailed anatomy of cortical surface with a high degree of similarity to operative findings even in the presence of cortical distortion, leading to various applications beyond navigation alone.

The development of hydrocephalus (HCP) necessitating placement of a ventriculoperitoneal shunt (VPS) after decompressive hemicraniectomy occurs at a rate of approximately 5%-15%. The ideal approach for addressing both HCP and a cranial defect remains unclear, and whether concomitant VPS and cranioplasty (CP) increases the risk of complications is uncertain. ⋯ In our study population, there was no difference between simultaneous and separate CP and VPS placement with respect to CP infection, VPS infection, and VPS mechanical failure/obstruction. There is equipoise in the current literature regarding the safety of performing these 2 common procedures simultaneously, with studies of similar size and design finding variable degrees of safety of this practice.

Multicenter Study
A multicenter retrospective cohort study of 'talk and die' after traumatic brain injury.
Patients who "talk and die" after traumatic brain injury (TBI) are potentially salvageable. The reported incidences and risk factors for the "talk and die" phenomenon are conflicting and do not take into account recent improvements in trauma care. The aim of this study was to determine the incidences of "talk and die" after TBI in a modern trauma care system, as well as associated risk factors. ⋯ Even in modern trauma care systems, some patients still talk and die after TBI. We identified certain risk factors in patients with TBI that elicit the requirement for close observation, even if these patients talk after TBI.

The diagnosis of Rathke cleft cysts (RCC) has increased in recent times as a result of improvements in imaging techniques; however, symptomatic patients are uncommon and accurate preoperative diagnosis may sometimes be difficult. The indications of surgical management protocol are evolving. We aim to provide a comprehensive review of clinical, imaging, and histopathologic features with operative management strategies along with outcome and prognosis in RCC. ⋯ RCCs are an uncommon disease with a wide spectrum of clinical and radiologic features. Endonasal endoscopic transsphenoidal surgery provides excellent clinical and endocrinologic improvement. We believe that radical excision does not necessarily result in endocrinologic impairment and may have a better impact on recurrence and cyst resolution.

To examine the long-term outcomes (minimum of 4.5 years) of endoscopic endonasal odontoidectomy (EEO) with preservation of anterior C1 ring to treat irreducible ventral bulbo-medullary compressions in rheumatoid arthritis (RA) and to illustrate a novel technique of anterior pure endoscopic craniovertebral junction (CVJ) reconstruction and fusion. In fact, long-term clinical studies are still lacking to elucidate the effective role of EEO and whether it can obviate the need for posterior fixation. ⋯ EEO with anterior C1 arch sparing provides satisfying long-term results for irreducible ventral CVJ lesions in RA. The preservation of anterior C1 arch and, when possible, the reconstruction of anterior CVJ can prevent the need for posterior fusion.
