Multicenter Study Comparative Study
Comparison of Radiation Exposure Among Three Different Endoscopic Discectomy Techniques for Lumbar Disc Herniation.
Lumbar disk herniation can be successfully treated by lumbar endoscopic spinal procedures. However, one of the most important disadvantages of the endoscopic methods used is radiation exposure. There are multiple endoscopic spinal procedures and this study aims to compare unilateral biportal endoscopic diskectomy (UBED), percutaneous endoscopic lumbar diskectomy (PELD), and microendoscopic diskectomy (MED) methods in terms of radiation exposure. ⋯ The more the level of invasiveness is reduced in spinal surgery, the greater the exposure to radiation. In this study, the groups are listed as PELD > UBED > MED according to the duration and level of radiation exposure.

Review Case Reports
Sinus Pericranii Complicated by Hydrocephalus. Case Report and Literature Review.
Sinus pericranii (SP) is a rare vascular condition that results when abnormal communication between the intracranial and extracranial venous systems is present. Here we report a rare case of hydrocephalus revealed through a SP scalp mass with a review of literature. ⋯ SP is divided into two main types: (1) Spontaneous type, in which lesions are formed due to acquired causes without a syndromic association or other vascular anomalies or stenosis. The most commonly reported cause is trauma in which SP may develop at the trauma site rather than the midline. (2) Congenital type, in which case the most commonly reported association is craniosynostosis. It can also be seen with vein of Galen hypoplasia, vein of Galen malformations, dural sinus malformations, solitary developmental venous anomalies, and intraosseous arteriovenous malformations. We are reporting the first case of idiopathic SP with hydrocephalus without a congenital association or acquired cause, including trauma. The sudden change in SP size can indicate a change in intracranial pressure and the development of hydrocephalus.

Ankylosing spondylitis (AS) is an inflammatory disease that involves above all the spine and the pelvis. In the spine, the inflammatory processes cause the formation of syndesmophytes between the vertebral bodies and the ossification of ligaments, with bony overgrowth. In this setting, dysphagia is a rare but severe complication and only a few cases have been reported in the literature. ⋯ Among the 5 reports (including the present case) available in the current literature with a clear dysphagia recovery follow-up, the present case (the second one harboring gastrostomy) is associated with the slowest complete recovery published so far. This unusually late recovery suggests a possible role not only of the mechanical decompression of the esophagus but also of the degeneration/regeneration ratio of the myenteric plexus, along with local neurotransmitters sensitivity changes, to better understand the dysphagia recovery time course of this unique patient.

Review
Cranioplasty: A Comprehensive Review of the History, Materials, Surgical Aspects and Complications.
Cranioplasty is a common neurosurgical procedure performed to reconstruct cranial defects. The materials used to replace bone defects have evolved throughout history. Cranioplasty materials can be broadly divided into biological and synthetic materials. ⋯ The effect of cranioplasty timing on cognitive function remains debatable. However, the timing of cranioplasty is independent of neurologic outcomes. In this article, the history, materials, complications, and evolution of current practices used in cranioplasty are comprehensively reviewed.

Review Case Reports
Primary Orbital Dedifferentiated Liposarcoma: A Case Report.
Primary dedifferentiated liposarcoma of the orbit is a rare condition. ⋯ Primary orbital dedifferentiated liposarcomas remain challenging for their diagnosis and standard treatment. Clinicians should keep in mind the possibility of liposarcoma with orbital tumors.
