Facial nerve (FN) schwannomas are extremely rare. According to their origin and involved segment(s), they constitute distinct subtypes. Intact FN function presents a management challenge, particularly in the cerebellopontine angle cisternal subtype that masquerades as a vestibular schwannoma. Fascicular-sparing technique with subtotal resection can maintain a good FN function. This study focuses on management to maintain good FN function. ⋯ FN schwannomas management is individualized according to the subtype and the FN function at presentation. When FN function is normal, observation can be applied for prolonged period of time. At the early sign of deterioration, sub- or near-total resection with fascicle sparing technique can be performed. The cisternal subtype masquerade as vestibular schwannoma and should be recognized at the initial exposure by the appearance of finely splayed nerve fascicles at the perimetry of the tumor which elicits a motor response at low threshold stimulation.

The addition of fusion surgery to the decompression for lumbar degenerative disorders remains controversial. The purpose of this study is to compare the rate and outcome of decompression and fusion versus decompression alone. ⋯ As compared with decompression alone, spinal fusion for degenerative lumbar disorders is associated with increased odds of adverse outcomes. These findings highlight the need for spine surgeons to consider carefully their indications for fusion procedures in the setting of degenerative spinal disorders.

Treatment of multiple recurrent chronic subdural hematomas (CSDH) is challenging. Identification of specific risk factors for multiple recurrences may allow a higher degree of personalized treatment, including closer postoperative follow-up, detailed prognostication, and a more aggressive initial surgical strategy, such as craniotomy, adjuvant embolization of the middle meningeal artery, or adjuvant medical treatment, such as steroids. The aim of this study was to identify pretreatment risk factors for a second recurrence of CSDH (re-re-CSDH) and risk factors for developing re-re-CSDH once operated for the first recurrence. ⋯ We found similar independent risk factors for re-CSDH and re-re-CSDH, and for re-re-CSDH once treated for re-CSDH. Hence, it was not possible to identify specific risk factors for patients at risk of re-re-CSDH at the time of the primary diagnosis.

Thoracic ossification of the posterior longitudinal ligament (TOPLL) is a rare but intractable disease, and is the second leading cause of thoracic myelopathy. This study aimed to illustrate the overall knowledge structure and development trends of TOPLL, using a bibliometric analysis and newly developed visualization tools. ⋯ The study showed an upward trend with a stable rise in recent years. Japan is country with the highest productivity, not only in quality, but also in quantity. Peking University and Spine have been the largest contributors. Indeed, this study provides great insights to the growth and development of TOPLL. Moreover, it will contribute to the growth of the international frontier.

U.S. neurosurgery programs are increasingly using social media accounts. We performed a search and analysis of social media accounts across all U.S. neurosurgical training programs with an attempt at understanding the relative utilization by various subspecialties. ⋯ Many U.S. neurosurgical programs have social media accounts with larger programs likely to have social media accounts. While there is a larger percentage of spine faculty within individual departments, vascular and oncology subspecialties are more likely to have a Twitter account. We suggest the need for increased engagement among spine faculty across social media platforms.
