To investigate the common complications from the microsurgical treatment of large intracranial vestibular schwannoma (VS) via suboccipital retrosigmoid approach and to propose strategies for minimizing such complications. ⋯ The key factors for reducing surgical complications include careful assessment of the functions of acoustic and facial nerves as well as a thorough understanding of anatomy via the retrosigmoid approach before operation, skillful microsurgical technique, and monitoring of multiple cranial nerves during resection.

Despite the increasing number of elderly patients undergoing neurosurgical interventions, there are limited resources for preoperative assessment of frailty in this population. We investigated the association between recent history of falls and surgical outcomes for these patients. ⋯ History of at least 1 fall in the 6 months before a neurosurgical operation was associated with increased risk of discharge to a facility, readmissions, and complications in the first 30 days after discharge. History of prior falls should be taken into account during the preoperative risk assessment of neurosurgical patients.

Negative-pressure hydrocephalus (NegPH), a very rare condition of unknown etiology and optimal treatment, usually presents postneurosurgery with clinical and imaging features of hydrocephalus, but with negative cerebrospinal fluid pressure. ⋯ We describe a NegPH case of -3 mm Hg intracranial pressure that was successfully treated to achieve 5 mm Hg under continuous intracranial pressure monitoring with horizontal positioning, head down and legs elevated to 10°-15°, neck wrapping for controlled venous drainage, chest and abdomen bandages, infusion of 5% dextrose fluid to lower plasma osmolarity (Na+, 130-135 mmol/L), daily cerebrospinal fluid drainage >200 mL, and arterial blood gas partial pressure of carbon dioxide >40 mm Hg.

Chronic subdural hematoma (CSDH), a common condition in elderly patients, presents a therapeutic challenge with recurrence rates of 33%. We aimed to identify specific prognostic factors for recurrence using quantitative analysis of hematoma volume and density. ⋯ Quantitative image analysis provided evidence that percentage of hematoma drained and postoperative CSDH density are independent prognostic factors for subdural hematoma recurrence.

Comparative Study
Comparison of transarticular screw fixation and C1 lateral mass-C2 pedicle screw fixation in rheumatoid arthritis patients with atlantoaxial instability.
Many surgical procedures have been introduced to manage atlantoaxial instability caused by rheumatoid arthritis (RA) to prevent complications and improve fusion rate. We report the surgical outcome between transarticular screw fixation (TAF) and C1 lateral mass-C2 pedicle screw fixation (C1LM-C2P) in patients with atlantoaxial instability from RA. ⋯ Two surgical techniques showed a good fusion rate by rigid fixation in the immediate postoperative period and fewer surgery-related complications in patients with RA. Because surgical complications are more likely during the learning curve (as with other surgical techniques), surgeons should carefully evaluate patients before surgery by radiologic and neurologic examinations.
