AI Article Synopsis
- Graft failure is a frequent issue in cranioplasty, necessitating revision procedures, and this study explores outcomes using custom-made 3D titanium implants for such revisions.
- In a review of 43 patients from 2011 to 2019, those with initial polymethyl methacrylate (PMMA) implants experienced a longer duration before needing revisions compared to those with autologous grafts (AG), without significant differences in hospital stay length.
- The findings suggest that while PMMA leads to longer timeframes before revision compared to AG, both show similar hospitalization results, and custom-made 3D titanium implants prove beneficial in reducing implant failure and addressing cosmetic issues.
Article Abstract
Objective: 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.
Methods: We evaluated 43 consecutive patients between January 2011 and December 2019 who underwent revision cranioplasty using 3D custom-made titanium implants. The 3D image of the patient's cranium and the plan to close the cranium defect were created in a virtual environment using software programs. Demographic and radiologic features were compared based on the materials used in the initial cranioplasty.
Results: Previous material was autologous graft (AG) in 27 patients and polymethyl methacrylate (PMMA) in 16 patients. The mean time without revision cranioplasty is longer in patients with PMMA implants than in patients with AG. There was no statistically significant difference in the length of hospital stay between patients with PMMA implants and patients with AG. There were no postoperative adverse events such as infection, wound dehiscence, convulsions, or epidural hematoma in 38 patients during hospitalization. Wound dehiscence developed in 5 patients and surgical repair was required in one.
Conclusions: 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.

Background: Calvarial defects in NF1 are rare and lack standardized management guidelines. This study seeks to shed light on calvarial defects in NF1 patients with extensive skull erosion.
Methods: This case report focuses on clinical and radiological presentations and surgical interventions during six years of follow-up, comparing the results with those in the literature.
Skull defect - Frontotemporal dementia sagging brain syndrome.

Department of Neurosurgery, Cedars-Sinai Medical Center, Los Angeles, California, USA.
Objective: Frontotemporal dementia (FTD) sagging brain syndrome is a disabling condition. An underlying spinal Cerebrospinal fluid leak can be identified in only a minority of patients and the success rate of non-directed treatments is low. Some of these patients have a remote history of craniectomy/cranioplasty and we report a positive response to custom implant cranioplasty revision many years after their initial cranioplasty.

Article Synopsis
- * A retrospective analysis was conducted on 23 patients who received axolotl dermis patches after surgical procedures, with data collected on demographics, post-surgery complications, and comorbidities affecting wound healing.
- * Results showed that only 8.7% of patients experienced complications such as infection or wound dehiscence after using the patches, suggesting a promising alternative for chronic wound management.

The role of autologous bone in cranioplasty. A systematic review of complications and risk factors by using stored bone.
Acta Neurochir (Wien)
November 2024
Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden.
Background: Autologous bone cranioplasty is associated with a high complication rate, particularly infections and bone resorption. Although there are studies on the incidence and risk factors for complications following autologous bone cranioplasty, the study design is typically limited to retrospective analysis with multiple statistical explorations in small cohorts from single centers. Thus, there is a need for systematic analysis of aggregated data to determine the rate and risk factors for cranioplasty complications.
