The United States is projected to face increasing physician-workforce shortages. However, the shortage in the neurosurgical workforce has not yet been characterized. In the present study, we outlined the current state of the neurosurgical workforce by quantifying the divide between the number of practicing neurosurgeons and the U.S. ⋯ Although the national NPCR has slowly increased during the past 5 years, a more recent decrease occurred within the last 3 years. Additionally, with almost 57% of surgeons having been practicing for >20 years, concern exists regarding whether current practices can sustain increasing patient needs. The results from the present study indicate that further investigation is warranted regarding the factors contributing to this shortage and the steps that can be taken to increase the production of well-trained neurosurgeons.

Sleep-wake disorders (SWDs) are associated with multiple systemic pathologies; however, the clinical risk that such disorders carry for spinal surgery patients is not well understood. In the present population-based study, we comprehensively evaluated the significance of sleep-related risk factors on instrumented spinal surgery outcomes. ⋯ SWDs confer an increased risk of morbidity and mortality for elective instrumented spine surgery. Understanding the specific contributions of SWDs to postoperative morbidity and mortality will help physicians implement prophylactic measures to reduce complications and improve postoperative patient recovery.

Granular cell tumors are rare vascular neoplastic lesions of the sellar and suprasellar region that usually arise from the pituitary stalk but can originate as low as the posterior pituitary or as high as the tuber cinereum.1 Complete resection, although ideal, can yield high rates of endocrine or visual morbidity.1,2 On headache workup, a 66-year-old woman was found to have a 1.2 × 1.1 × 1.3-cm contrast-enhancing lesion in the anterior-inferior third ventricle, posterior to the infundibulum. Endocrine testing was unremarkable, and a lumbar puncture was nondiagnostic. An open biopsy and possible resection were selected by the patient over short-interval imaging. ⋯ Postoperatively, the patient had transient diabetes insipidus, with preserved vision and normal endocrine function on follow-up. The trans-lamina terminalis approach can be used for safe resection of anterior third ventricular tumors. Preservation of the floor and walls of the third ventricle is critical to avoid morbidity.

To compare location and amount of unremoved intervertebral disc between extreme lateral lumbar interbody fusion (XLIF) and oblique lateral lumbar interbody fusion (OLIF). ⋯ Our study found a greater area of unremoved disc in OLIF compared with XLIF. The common locations were in the contralateral side of the surgical approach-right anterior in OLIF, and right posterior in XLIF. The greater area of the unremoved disc in the anterior zone after OLIF due to oblique corridor to disc space may cause cage malposition. Meticulous disc removal should be performed, especially in OLIF, to prevent complications.

Spinal meningiomas are the common benign tumors in intradural extramedullary spinal tumors. Simpson grade I resection is recommended to avoid tumor recurrence. However, the dura reconstruction increases a risk of cerebrospinal fluid leakage after this surgical resection. To address this concern, the inner dura layer resection and long-term surgical outcomes of this technique were designed and examined after total tumor resection to preserve the outer dura layer. ⋯ A long-term postoperative follow-up indicated that this modified spinal dura preservation technique caused good neurologic improvement with rare recurrence. Therefore we recommend this improved technique may be an alternative surgical option for total resection of spinal meningiomas with favorable prognosis.
