Review Comparative Study
Endocrinological and ophthalmological consequences of an initial endonasal endoscopic approach for resection of craniopharyngiomas.
The expanded endoscopic approach to craniopharyngiomas has recently been described in several small case series. The authors present their experience with this technique and review the available literature. ⋯ The endoscopic endonasal approach is a minimally invasive alternative to open transcranial approaches for select craniopharyngiomas. Similar to previous transcranial series, rates of endocrinopathy and gross-total resection were dependent upon the adherence of the tumor capsule to the hypothalamus, pituitary stalk, and associated vasculature. A review of the literature suggests that the results of the current series are similar to other published series on this topic.

Comparative Study
Early outcomes of endoscopic transsphenoidal surgery for adult craniopharyngiomas.
Although the transsphenoidal approach for subdiaphragmatic craniopharyngiomas has been performed for many years, there are few reports describing the role of the endoscopic transsphenoidal technique for suprasellar craniopharyngiomas. The purpose of this study was to report the outcomes of the endoscopic transsphenoidal approach for adults with craniopharyngiomas in whom the goal was gross-total resection. ⋯ The authors have achieved a high rate of radical resection and symptomatic improvement with the endoscopic transsphenoidal technique for both subdiaphragmatic (sellar/suprasellar) and supradiaphragmatic (suprasellar) craniopharyngiomas. However, this is also associated with a high incidence of new endocrinopathy. Endoscopic assessment of tumor resection may be more sensitive for residual tumor than the first postoperative MR imaging study.

Giant craniopharyngiomas in the retrochiasmatic space are challenging tumors, given the location and surrounding vital structures. Surgical removal remains the first line of therapy and offers the best chance of cure. For tumors with extension into the retrochiasmatic space, the authors use the translamina terminalis corridor via the transbasal subfrontal approach. ⋯ This provides the significant advantage of visualization of both walls of the third ventricle and hypothalamus as well as inferior midline access to the interpeduncular cistern to permit safe neurovascular dissection and total tumor removal. In this report, the authors describe the transbasal subfrontal translamina terminalis approach, with specific emphasis on technical surgical nuances in removing retrochiasmatic craniopharyngiomas. An illustrative video demonstrating the technique is also presented.

Review Meta Analysis
Adult scoliosis surgery outcomes: a systematic review.
Appreciation of the optimal management of skeletally mature patients with spinal deformities requires understanding of the natural history of the disease relative to expected outcomes of surgical intervention. Appropriate outcome measures are necessary to define the surgical treatment. Unfortunately, the literature lacks prospective randomized data. The majority of published series report outcomes of a particular surgical approach, procedure, or surgeon. The purpose of the current study was to systematically review the present spine deformity literature and assess the available data on clinical and radiographic outcome measurements. ⋯ Surgery for adult scoliosis is associated with improvement in radiographic and clinical outcomes at a minimum 2-year follow-up. Perioperative morbidity includes an approximately 13% risk of pseudarthrosis and a greater than 40% incidence of perioperative adverse events. Incidence of perioperative complications is substantial and must be considered when deciding optimal disease management. Although the quality of published studies in this area has improved, particularly in the last few years, the current review highlights the lack of routine use of standardized outcomes measures and assessment in the adult scoliosis literature.

Comparative Study
Mid-term to long-term clinical and functional outcomes of minimally invasive correction and fusion for adults with scoliosis.
The goal of this study was to assess the operative outcomes of adult patients with scoliosis who were treated surgically with minimally invasive correction and fusion. ⋯ Minimally invasive surgical correction of adult scoliosis results in mid- to long-term outcomes similar to traditional surgical approaches. Whereas operating times are comparable to those achieved with open approaches, blood loss and morbidity appear to be significantly lower in patients undergoing minimally invasive deformity correction. This approach may be particularly useful in the elderly.
