Background: Single-stage surgical treatment of cranial intraosseous meningiomas includes complete tumor resection followed by aesthetic reconstruction. Tailored tumor resection with a computer-aided design/computer-aided manufacturing custom-made implant for the defect has been advocated in recent years to achieve a satisfactory cosmetic result with reduced operative time and fewer complications. However, several technical nuances related to the area of osseous removal may compromise cranioplasty.
Methods: We present 2 cases of intraosseous meningiomas (sphenoid wing and retromastoid) to illustrate a step-by-step approach, from preoperative planning to single-step surgery.
Results: For each case, a customized frame template delimiting bone removal was designed using cranial sutures as anatomical landmarks for precise placement of the cranioplasty template over the area of interest.
Conclusions: Custom templates based in cranial sutures may benefit single-step frame-guided resection and reconstruction of intraosseous tumors with compelling results.

Objective: Patients with a history of surgery for single-suture craniosynostosis (SSC) as an infant often wish to participate in sports later in childhood. However, there are no established guidelines from neurosurgeons and craniofacial surgeons to guide parents in which sports their child should or should not participate. Therefore, this study aimed to evaluate the attitudes and practice patterns of experienced neurosurgeons and craniofacial surgeons regarding the counseling of caregivers of these patients about sports participation.

Background: Sutural anatomy variation has long been a topic of debate among anatomists, paleontologists, and morphologists. While the exact reasons for the prevalence of this variance remains a topic of ongoing discussion, developmental and genetic factors are hypothesized to be the main reasons. Understanding the morphology and occurrence of normal sutural variations in pediatric patients is essential to making the right diagnosis, where a misinterpretation of a sutural bone may lead to an inaccurate assessment, completely misleading the diagnostic process.

Craniosynostosis limits normal cranial growth, significantly affecting the growth and development of children. This increase in intracranial pressure results in significant cosmetic and functional losses. This study investigated the efficacy of combining molding helmets with suturectomy for craniosynostosis.
