Graft failure is a common complication of cranioplasty. Revision cranioplasty is required to overcome this complication. However, no previous studies have reported outcomes in revision cranioplasty with 3-dimensional (3D) custom-made titanium implants. We describe our experience with 3D titanium implants in patients with revision cranioplasty. ⋯ Initial cranioplasty with PMMA provides a longer time period than the AG before the revision. However, both of them have similar outcomes based on length of hospital stay and cranial defect area. Custom-made 3D titanium implant is a good option for revision cranioplasty to prevent implant failure and reduce patients' cosmetic concerns.

A retrospective study was performed to observe and measure the safe distance between the uncinate process (UP) and the V2 vertebral artery (VA). ⋯ UP and PT could be seen as landmarks in the operations of anterior cervical discectomy and fusion. The safe space outside UP is about 4 mm and more care should be taken when operating on the caudal spine. The safe space outside PT is about 10 mm and more care should be taken when operating on the cephalad spine. The safe space for operation from the PT to the ventral side is about 4.5 mm, and more care should be taken when operating on the cephalad side of the cervical spine.

Minimizing Invasiveness in Neurosurgical Osteotomies: A Comparative Histomorphometric Study of Piezoelectric Craniotomy versus High-Speed Drill.
Piezoelectric bone cutting has gained popularity in neurosurgical osteotomies due to perceived lower trauma compared to rotary instruments. However, histological confirmation of its decreased aggressiveness is lacking, hindering conclusive proof. This study compares the bony and neuro-meningeal invasiveness of piezoelectric craniotomy with high-speed drill techniques. ⋯ Piezoelectric craniotomy preserves residual osteoblast viability and leptomeningeal integrity while demonstrating lower rates of thermally induced gliosis and histiocytic infiltration compared to high-speed drills. This suggests the piezoelectric osteotome's minimal invasiveness in bone, meningeal, and brain tissue.

To evaluate the effect of the basilar invagination (BI) type B on cervical spine. ⋯ The deformation of skull base in the BI of type B caused, on average, a hyperlordosis of almost 30° in the C2-C6 segment. This change was approximately 17° in the C2-C4, with the clivus hypoplasia being a risk factor for cervical hyperlordosis.

Over the past 15 years, WORLD NEUROSURGERY (WN) has emerged as a pivotal source in the neurosurgery field, reflecting remarkable growth and development. Originally published as Surgical Neurology from 1973 to 2009, the journal transitioned to its current title in 2010, significantly expanding its reach and influence. ⋯ This study underscores WN's significant role in advancing neurosurgical research over the past 5 null decades. The findings highlight the journal's evolution, its expanding global influence, and the key contributors to its success.
