Supracerebellar infratentorial approach with paramedian expansion for posterior third ventricular and pineal region lesions.
Surgical treatment for lesions in the posterior third ventricle is technically challenging. Surgical approaches to this area carries a risk of both venous and neural injury, with subsequent morbidity. Several approaches are used to reach the pineal region. The supracerebellar infratentorial approach is the commonly approach used for such lesions. ⋯ The paramedian expansion offers a better lateral and inferior tumor resection and a better view of the contralateral extension within the posterior third ventricle. Collicular lesions are better controlled using this approach by gentle inferior and lateral retraction of the cerebellum. The expanded supracerebellar infratentorial approach allows for working on the lateral tumor extension without jeopardizing the deep venous system.

Risk factors for meningitis after craniotomy in patients with subarachnoid hemorrhage due to anterior circulation aneurysms rupture.
Postoperative meningitis is a serious complication occurring after neurosurgical interventions. However, few investigations have focused specifically on the risk factors that predispose patients to meningitis after major craniotomy. This study identified the risk factors for postoperative meningitis after neurovascular surgery, and investigated the relationship between postoperative meningitis and clinical outcome. ⋯ Meningitis after surgery is still a serious complication that requires preventative intervention. The clinical outcome of patients with postoperative meningitis after neurovascular surgery is not still satisfactory.

A minimally invasive approach to defects of the pars interarticularis: Restoring function in competitive athletes.
To understand that young athletes have a higher incidence of pars interarticularis defects than the general population. This may be due to an immature spine put under higher stress loads at an early age. Traditionally, surgery was reserved for those who failed conservative therapy, and consisted of open exposure, bone grafting and placement of pedicle screws. This leads to a long recovery period and limited ability to return to competitive sport. ⋯ MIS advantages include less muscle tissue disruption and restoration of the natural anatomy. This leads to a more rapid recovery, decreased perioperative pain, minimal blood loss, earlier mobilization and decreased hospital length of stay. Overall this allows the athlete to start therapy earlier and return to competition sooner and at his/her pre-operative competitive level. The described MIS repair technique outcomes are similar to those that have been reported in the literature and have allowed a high rate of return to athletics in high performing patients; critical to their quality of life.

Microvascular decompression and MRI findings in trigeminal neuralgia and hemifacial spasm. A single center experience.
For patients with medically unresponsive trigeminal neuralgia (TIC) and hemifacial spasm (HS), surgical microvascular decompression (MVD) is the procedure of choice. The authors of this report sought to review their outcomes with MVD in patients with TIC and HS, and the success of preoperative magnetic resonance imaging (MRI) in identifying the offending vascular compression. ⋯ MVD is an effective and safe modality of treatment for TIC and HS. In addition to ruling out structural lesions, MRI can offer additional information by highlighting vascular loops associated with compressions. On conventional scans as obtained here, the resolution of MRI was congruent with operative findings in 84% in TIC and 75% in HS. This review emphasizes that the decision to undertake MVD in TIC or HS should be based on clinical diagnosis and not visualization of a compressing vessel by MRI. Conversely, the presence of a compressing vessel by MRI demands perseverance by the surgeon until the nerve is decompressed.
