The aim of this study was to describe the anatomic trajectory of the extracranial needle for percutaneous rhizotomy and correlate this with structures at risk during such a procedure. ⋯ To our knowledge, this is the first study to describe the detailed extracranial anatomic needle pathway using the Hartel approach. Such data might help surgeons better recognize potential complications from such procedures.

Parasagittal meningiomas arise from the arachnoid cells of the angle formed between the superior sagittal sinus (SSS) and the brain convexity. In this retrospective study, we focused on factors that predict early recurrence and recurrence times. ⋯ Male sex is an independent risk factor for recurrence that, associated with other factors such tumor size and histologic type, explains 74.5% of all cases in a binary regression model.

Management of encephaloceles is challenging when massive brain herniation is present. In such instances, an expansile cranioplasty may be attempted so as to preserve some herniated brain tissue. Complications such as wound dehiscence, cerebrospinal fluid leak, and scalp necrosis are postoperative concerns. The treatment of scalp necrosis with dural and brain exposure is certainly a challenge due to the complexity of flap techniques in such a young age. Herein we describe the use of a novel technique for the management of a scalp necrosis and dehiscence in an infant. ⋯ A simple technique, such as the use of an artificial dermal matrix with simultaneous split-thickness skin graft, may be an effective treatment for the repair of scalp defects, even when coverage of exposed brain tissue is necessary, when no other techniques are found to be suitable.
