External ventricular drain (EVD) placement is required frequently in neurosurgical patients to divert cerebrospinal fluid and monitor intracranial pressure. The usual practice is the tunneled EVD technique performed in operating theaters. EVD insertion through a bolt in intensive care also is described. We employ both practices in our institute. Herein, we compare the indications, accuracy, safety, and costs of the 2 techniques. ⋯ Bedside bolt EVD placement is safe, accurate, and cost effective in selective patients with hemorrhage-related hydrocephalus.

Pneumocephalus is commonly associated with cranial trauma including surgical interventions. Spontaneous pneumocephalus on the other hand is a rare diagnosis. Reported cases were predominantly unilateral. We report a unique case of a bilateral spontaneous pneumocephalus probably related to a bilateral tegmen defect related to repeated Politzer maneuvers. ⋯ Spontaneous pneumocephalus represents a rare condition often associated with increased middle ear pressure, which can be caused by autoinflation (e.g., Valsalva or Politzer maneuver), sneezing, or coughing. The described case represents a unique presentation of the bilateral spontaneous pneumocephalus associated with bilateral tegmen and dura mater defects managed surgically. Despite its rarity, spontaneous pneumocephalus originating from the temporal bone should be considered as a possible diagnosis in patients with suggestive otologic presentation (e.g., tinnitus, instability, hearing loss) and associated nonspecific neurologic symptomatology.

Observational Study
Feasibility of Staged Bilateral Radiofrequency Vim Thalamotomy for Bilateral Essential Tremor.
Patients with bilateral and/or midline/axial tremor have significant diminution in quality of life (QOL). Various studies report high complication rates with bilateral thalamotomy. However, use of primitive methods in these studies confers questionable validity. We conducted a retrospective observational cohort study in patients with medication-refractory bilateral essential tremor treated with staged bilateral radiofrequency ventral intermediate nucleus thalamotomy to subjectively examine the impact of any adverse effects on QOL and patient satisfaction. ⋯ Adverse effects that are nondisabling and hence acceptable to the patient can be considered acceptable adverse effects. Staged bilateral radiofrequency ventral intermediate nucleus thalamotomy definitely improves QOL in patients with medication-refractory bilateral essential tremor despite occurrence of acceptable adverse effects.

Few prognostic markers are available for patients with non-small-cell lung cancer (NSCLC) undergoing neurosurgical resection of symptomatic brain metastases. ⋯ Patients requiring surgical resection of an epidermal growth factor receptor-mutated NSCLC brain metastasis had an associated improved survival compared with patients without this mutation, independent of tyrosine kinase inhibitor use. Decreased survival was associated with older age, multiple previous brain radiation therapies, and extracranial metastasis.

To compare the outcome of anterior cervical decompression and fusion (ACDF) and posterior laminoplasty (LAMP) for treating 4-level cervical spondylotic myelopathy (CSM). ⋯ Both ACDF and LAMP were effective in the treatment of multilevel CSM. Compared with LAMP, ACDF is less invasive and may be more suitable for elderly patients with poor tolerance of surgery.
