Tobacco use is known to affect incidence and postoperative outcome for several neurosurgical disorders, but its relationship to trigeminal neuralgia (TN) is not known. We sought to identify unique population characteristics that correlate with tobacco use in a cohort of patients with TN who underwent microvascular decompression (MVD), including effect on long-term postoperative outcome. ⋯ In patients undergoing MVD for TN, smoking is associated with younger age of TN onset, more widespread facial pain, and worse long-term postoperative outcome after MVD. These features suggest that TN in smokers may represent a more severe disease form compared with TN in nonsmokers with different responses to treatment.

Predicting the development of adjacent segment disease (ASD) after lumbar spine fusion would help guide preoperative and postoperative therapies to prevent reoperation. We sought to evaluate whether sarcopenia predicts the development of early ASD after transforaminal lumbar interbody fusion (TLIF). ⋯ Sarcopenia, measured by decreased psoas area and P:VBR, predicts ASD formation within 3 years of surgery. Morphometric analysis of psoas size is a simple tool to identify patients at risk of developing ASD. This information can potentially guide preoperative and postoperative therapies, affect surgical decision making, and effectively counsel patients on risks of reoperation.

Several studies have explored strategies to prevent proximal junctional kyphosis (PJK) which is the unresolved issue in adult spinal deformity (ASD) surgery. This study aimed to investigate the preventive effects of upper instrumented vertebrae (UIV) recombinant human bone morphogenetic protein-2 (rhBMP-2) with beta-tricalcium phosphate (β-TCP) carrier injection on PJK. ⋯ The transpedicular injection of rhBMP-2/β-TCP carrier at the UIV significantly contributed to the prevention of PJK and effectively increased trabecular bone density at the UIV.

Cervical myelopathy caused by C3-4 level degeneration often exhibits different characteristics after anterior cervical discectomy and fusion (ACDF) than other cervical levels. This study compared the outcomes of C3-4 ACDF with surgeries at other levels and identified risk factors of 30-day reoperation after ACDF. ⋯ Surgery on C3-4 level showed a higher risk of 30-day reoperation than other levels. It is likely due to C3-4 surgical level, and ligament flavum hypertrophy contributes to cord compression, particularly in the unstable early postoperative period.

Many patients with unruptured intracranial aneurysms (UIAs) remain untreated if the risk of treatment exceeds the estimated risk of aneurysm rupture, potentially leading to diagnosis-related stress and anxiety. Working status may serve as a marker for the total level of function including mental health and psychological burden of the condition. The aim of the study was to assess the working status before and after a diagnosis of an untreated UIA. ⋯ The work participation of patients diagnosed with UIA is low prediagnosis compared with the general population and decreases significantly postdiagnosis.
