Analysis of Complications After Cranioplasty with a Customized Three-Dimensional Titanium Mesh Plate.

Abstract

To report outcomes of cranioplasty (CP) with a customized three-dimensional (3D) titanium mesh plate and identify the relationship between various clinical variables and complications after CP. Twenty patients who underwent surgery with customized 3D titanium mesh plates and had follow-up for >6 months from January 2015 to December 2017 were enrolled. Complications related to CP were retrospectively reviewed. Patients were divided into 2 groups (no complication group and complication group), and clinical variables related to complications were compared between the 2 groups. Correlation analysis was performed to identify the clinical variable significantly correlated with complications after CP with a customized 3D titanium mesh plate. Of 20 patients, 11 developed complications, including extrusion, intracranial infection, severe operative site pain, and wound dehiscence. Among the clinical variables, only the presence of a ventriculoperitoneal shunt was significantly correlated with the overall complication rate (odds ratio = 18.66; 95% confidence interval, 1.56-222.92; P = 0.021). A customized 3D titanium mesh plate is associated with a lower risk of intracranial infection, but the rate of postoperative complications, mainly cosmetic problems, such as forehead mesh extrusion and dehiscence, was high at 55%. A ventriculoperitoneal shunt was significantly correlated with the overall complication rate after CP with a customized 3D titanium mesh plate.
