Case Reports
Bifid facial nerve with dual origin identified during resection of vestibular schwannoma.
Facial nerve identification and preservation is a critical step in the resection of vestibular schwannoma. The use of intraoperative neurostimulation to positively identify the facial nerve along its entire course is essential to prevent injury. ⋯ Both roots were visualized to join as one facial nerve trunk outside the brainstem in the cisternal segment of the facial nerve, and both trunks demonstrated positive signal with neurostimulation. This case highlights an important anatomic variation and also the importance of correct identification of facial nerve anatomy during resection of vestibular schwannoma and other pathologies within the cerebellopontine angle.

Review Case Reports
Symptomatic Diffuse Vasospasm following resection of Temporal Ganglioglioma: literature review of literature with case- illustration.
Symptomatic cerebral vasospasm may occur in the setting of aneurysmal subarachnoid hemorrhage, traumatic brain injury, or after anterior skull base surgery, but its occurrence is extremely rare in the background of glioma surgical resection. ⋯ The risk factors, likely pathogenesis and the importance of early diagnosis and timely institution of treatment, in such cases are discussed in the background of relevant literature. The current case represents the first report of symptomatic diffuse vasospasm occuring after surgical resection of intracranial ganglioglioma in the Western literature.

Schwannomas encompassing the superior parapharyngeal space are challenging lesions because of the anatomical complexity of this region and the frequent involvement of the neurovascular structures of the jugular foramen. The purpose of this study is to report the technical aspects and the advantages of the anterolateral approach, here proposed for schwannomas of this complex area. ⋯ The anterolateral approach is highly effective in the treatment of retrostyloid superior parapharyngeal space schwannomas involving the jugular foramen. Its simplicity of execution, versatility, and very low morbidity are among its main strengths.
