Continuous monitoring of intracranial pressure after endoscopic third ventriculostomy in the management of CSF shunt failure.
The effectiveness of continuous intracranial pressure (ICP) monitoring in the adaptation period, after endoscopic third ventriculostomy (ETV), and removal of the failed shunt in the management of CSF shunt failure is assessed. ⋯ Post-operative continuous ICP monitoring and EVD insertion were very useful in the treatment of CSF shunt failure with ETV. This procedure allowed intermittent CSF drainage, relieving symptoms of elevated ICP, and provided accurate assessment of the success of the ETV and patency of the stoma in the early postoperative days by CT ventriculography and can also be used to install antibiotics in cases of infection.

Comparative StudyComparison of unilateral hemilaminotomy and bilateral hemilaminotomy according to dural sac area in lumbar spinal stenosis.
Unilateral hemilaminotomy (ULH) and/or bilateral hemilaminotomy (BLH) with limited facetectomy are defined approaches to decompress the thecal sac and exiting lumbar nerve roots without increasing the risk of subsequent spinal instability. ⋯ A unilateral approach with bilateral decompression and bilateral approach with bilateral hemilaminotomy are both minimal invasive, adequate and safe approaches with excellent prognosis. However, BLH leads to a bigger expansion of DSA.

Surgical repair of persisting CSF leaks following standard or extended endoscopic transsphenoidal surgery for pituitary tumor.
In this article, the aim of the authors is to discuss their experience with skull base reconstruction in endoscopic transsphenoidal and extended transsphenoidal surgery for pituitary tumor resection. ⋯ More complex defects after pituitary surgery should be repaired with a multilayer technique, using autologous materials such as fat, fascia lata, bone and mucoperiosteum taken from the middle turbinate. This type of autologous material is generally reliable in more complex defects, and it appears to be easy to harvest and handle for repair.

Comparative StudyMinimally invasive approach versus traditional open approach for one level posterior lumbar interbody fusion.
While over the last ten years minimally invasive posterior lumbar interbody fusion (PLIF) has been acknowledged to (i) reduce approach-related morbidity associated with quicker recovery, (ii) require a shorter hospital stay and (iii) deliver similar clinical outcomes when compared to a traditional approach, it is still not the current gold standard. In order to demonstrate the efficacy of the minimally invasive lumbar PLIF approach, a retrospective study was conducted comparing both approaches. ⋯ This study confirmed the results of previous studies which advocated the advantages of less blood loss, less postoperative pain, quicker recovery and shorter duration of hospitalization. However, in the long run, one year after surgery, both groups showed no significant difference with regards to clinical and radiographic outcome. Therefore long-term controlled studies are necessary to validate the role of the minimally invasive PLIF in degenerative lumbar instability.

The supraorbital craniotomy for access to the skull base and intraaxial lesions: a technique in evolution.
The supraorbital craniotomy was initially described as a minimally invasive means to target extra-axial lesions in the anterior cranial fossa and sellar/parasellar region. Since its initial description, various modifications have been described. We report our recent experience with this approach (and its modifications) for not only extra-axial but also intra-axial neoplastic pathology. ⋯ The supraorbital craniotomy and its modifications provide an ideal anterior subfrontal approach through which a wide variety of pathology can be approached. This technique has particular considerations in comparison to traditional cranial base approaches that must be taken into account before it is utilized.
