PURPOSE: Traditional cranioplasty methods focus on pre-operative or intraoperative hand molding. Recently, CT-guided @entity12316 (PEEK) plate reconstruction enables precise, time-saving reconstruction. This case series aims to show a single institution experience with use of PEEK cranioplasty as an effective, safe, precise, reusable, and time-saving cranioplasty technique in large, @entity129 . METHODS: We performed a 6-year retrospective review of cranioplasty procedures performed at our affiliated hospitals using PEEK implants. A total of nineteen @entity1 underwent twenty-two cranioplasty procedures. Pre-operative, intra-operative, and post-operative data was collected. RESULTS: Nineteen @entity1 underwent twenty-two procedures. Time interval from injury to loss of primary cranioplasty averaged 57.7 months (0-336  mo); 4.0 months (n  =  10, range 0-19) in cases of @entity130 . Time interval from primary cranioplasty loss to PEEK cranioplasty was 11.8 months for @entity281 (n  =  11, range 6-25  mo), 12.2 months for @entity130 (n  =  5, range 2-27  mo), and 0.3 months for cosmetic or functional reconstructions (n  =  3, range 0-1). Similar surgical techniques were used in all @entity1 . Drains were placed in 11/22 procedures. Varying techniques were used in skin closure, including adjacent tissue transfer (4/22) and free tissue transfer (1/22). The PEEK plate required modification in four procedures. Three @entity1 had reoperation following PEEK plate reconstruction. CONCLUSION: Cranioplasty utilizing CT-guided PEEK plate allows easy inset, anatomic accuracy, mirror image aesthetics, simplification of complex 3D defects, and potential time savings. Additionally, it's easily manipulated in the operating room, and can be easily re-utilized in cases of intraoperative course changes or @entity281 .
