Balloon compression of the rootlets behind the trigeminal ganglion for the treatment of trigeminal neuralgia has become an increasingly popular method among neurosurgeons. However, the method has recognized complications, including double vision. Although occurring infrequently, diplopia may cause the patient significant disability. To minimize the risk for this complication, we analyzed our patients with respect to the surgical technique. ⋯ By meticulous surgical technique with close attention to the anatomic position and the shape of the inflated balloon, most cases of postcompression diplopia should be avoided.

There is little information about in-hospital complication rates, adverse outcomes, and mortality after spinal fusion for cervical spondylotic myelopathy (CSM). The aim of this study was to report inpatient mortality, complications, and outcomes on a national level. ⋯ We provide a national estimate of inpatient complications and outcomes after spinal fusion for CSM patients in the United States. We demonstrate the impacts of age, complications, and medical comorbidities on the outcome of surgery for patients with this common disorder. We provide complication rates stratified by age and medical comorbidities for elderly patients who present with CSM who need spinal fusion.

We report the youngest known case of a prepontine intradural chordoma. These tumors are exceedingly rare. Unlike their more common extradural counterparts, no recurrence of an intradural chordoma has been reported. ⋯ By using an endoscopic-assisted procedure, we achieved complete resection of an intradural chordoma offering a potential for surgical cure. Resection is particularly advantageous because it spares the young child the need for radiation treatment. Close follow-up is warranted because we postulate that this tumor exists in a biological continuum between benign notochordal hamartomatous remnants and typical invasive chordomas.

The response to shunt surgery for idiopathic normal-pressure hydrocephalus (INPH) is variable because INPH is difficult to distinguish from other conditions causing the same symptoms. To date, no clinical picture or diagnostic test can distinguish INPH or predict response to cerebrospinal fluid (CSF) shunt surgery. We reviewed our 10-year experience with INPH to characterize long-term outcome and to identify independent predictors of outcome after shunt surgery. ⋯ INPH can be diagnosed accurately with CSF pressure monitoring and CSF drainage via a spinal catheter. CSF shunting is safe and effective for INPH with a long-term shunt response rate of 75%. Independent predictors of improvement are the presence of gait impairment as the dominant symptom and shorter duration of symptoms.

We sought to assess the value of adjusting shunt valve opening pressure, complications, and outcomes with the use of an adjustable shunt valve in the treatment of patients with normal-pressure hydrocephalus (NPH). ⋯ Noninvasive, particularly consecutive, minor or single larger adjustments to the valve opening pressure can further improve outcome in patients with NPH who undergo shunting.
