Review Comparative Study
Effectiveness of intraventricular endoscopic lamina terminalis fenestration in comparison with standard ETV: a systematic review of the Literature.
Endoscopic third ventriculostomy is a consolidated technique for the treatment of hydrocephalus. Despite its effectiveness and feasibility, several technical limitations about its use in certain situations have been described. Lamina terminalis-endoscopic third ventriculostomy (LT-ETV) has been proposed as an alternative technique. Authors systematically reviewed the literature in order to define the effectiveness and limits in comparison with standard ETV. ⋯ LT-ETV can be considered a successful technical option when standard ETV cannot be performed, although more complex cerebrovascular anatomy is involved. Therefore we suggest that lateral terminalis fenestration is a valid technical option in experienced hands.

For many years, the right hemisphere (RH) was considered as nondominant, especially in right-handers. In neurosurgical practice, this dogma resulted in the selection of awake procedure with language mapping only for lesions of the left dominant hemisphere. Conversely, surgery under general anesthesia (possibly with motor mapping) was usually proposed for right lesions. ⋯ These original findings, which break with the myth of a nondominant RH, may have important implications in cognitive neurosciences, by improving our knowledge of the functional connectivity of the RH, as well as for the clinical management of patients with a right lesion. In brain surgery, awake mapping should be considered more systematically in the RH. Moreover, neuropsychological examination must be achieved in a more systematic manner before and after surgery within the RH, to optimize care by predicting the likelihood of functional recovery and by elaborating specific programs of rehabilitation.

This review seeks to synthesize emerging literature on the effects of back muscle size on outcomes in spine surgery. Risk factors that contribute to poor surgical outcomes continue to be an area of interest in spine surgery because proper risk stratification can result in reduction in morbidity and enhanced patient care. However, the impact of muscle size on spine surgical outcomes is an understudied avenue with paucity of data evaluating the relationship among back muscles and surgical outcomes, patient's quality of life, and functional improvement postoperatively. ⋯ With reduction in surgical complications and improvement in postoperative functional outcomes, back muscle morphometry ought to be included in the preoperative surgical planning as a predictor of outcomes.
