To explore the effect of preoperative planning using mixed reality (MR) on training of percutaneous transforaminal endoscopic discectomy (PTED). ⋯ MR technology contributes to preoperative planning of PTED and is beneficial in the training of PTED. It significantly reduces puncture times and fluoroscopy times, providing a standardized method for the training of PTED.

Internal Carotid Artery Bleed: A Rare Complication Of Invasive Sphenoidal Aspergillosis.
Invasive sinonasal aspergillosis is rarely seen in immunocompetent individuals. It may involve adjacent intracranial and intraorbital structures causing high morbidity and mortality. ⋯ This case emphasizes the need for early diagnosis of invasive fungal sinusitis to prevent intracranial complications and fatal outcome. When the diagnosis is made, aggressive treatment with surgical débridement and adjuvant antifungal therapy is required. Internal carotid artery involvement is a rare but life-threatening complication of invasive fungal sinusitis.

Survival in Patients with High-Grade Spinal Meningioma: An Analysis of the National Cancer Database.
To report baseline demographics and examine for differences in survival for patients with World Health Organization (WHO) grade II and III spinal meningioma. ⋯ No difference in overall survival was identified between patients with WHO grade II or III spinal meningioma, although a trend was seen toward worse survival for patients with WHO grade III lesions.

Brain parenchyma herniation through a disrupted inner table into an enlarged diploic cavity with an intact outer table is described as intradiploic encephalocele. Intradiploic encephaloceles share common morphologic characteristics with expanding skull fractures and intradiploic arachnoid cysts. Herein, we describe a case of traumatic occipital intradiploic encephalocele. ⋯ Intradiploic encephaloceles have different features compared with the classic encephalocele and can be considered as a variant of expanding skull fracture and intradiploic arachnoid cyst.

Several diseases that involve the optic canal or its contained structures may cause visual impairment. Several techniques have been developed to decompress the optic nerve. ⋯ The MiniEx approach is an excellent alternative to traditional approaches for extradural anterior clinoidectomy and optic nerve decompression. It may be used as a part of more complex surgery or as a single surgical procedure.
