THE TRANSSPHENOIDAL APPROACH for sellar tumors has evolved significantly since it was described initially during the first decade of the 20th century. The approach currently incorporates technological advancements and refinements in patient selection, operative technique, and postoperative care. ⋯ This variability is a reflection of surgeon's preference, the lessons of experience, and the bias inherent in neurosurgical training. The methods and preferences described herein embody the distillation of an experience gained from 3900 transsphenoidal operations.

Previous reports of seizure outcomes after arteriovenous malformation (AVM) treatment have involved single-treatment modality (surgery, radiosurgery, or embolization) series. Such series reflect only selected lesions, of certain sizes, locations, and other clinical and anatomic characteristics, that are amenable to the single therapy, limiting the analysis of those factors. We report the results of AVM treatment using a multimodality approach that we think encompasses a broader spectrum of treatable brain AVMs. We tested for factors associated with seizure presentation and seizure outcomes. ⋯ Certain factors, as identified in an analysis of a wide spectrum of treatable brain AVMs, can facilitate predictions of the incidence of seizure presentation with AVMs, as well as seizure outcomes after multimodality treatment.

Use of the telescopic plate spacer in treatment of cervical and cervicothoracic spine tumors.
We investigated the mechanical and in vivo properties of a novel device, called the telescopic plate spacer (TPS), designed to promote restoration of height, alignment, and stability after cervical corpectomy for tumor. ⋯ The TPS can be used to restore height, alignment, and stability after corpectomy.
