Study Summary:
This retrospective bicenter study analyzed the complications associated with different implant materials used in cranioplasty (CP) after decompressive hemicraniectomy (DHC). The materials evaluated were autologous bone flap (ABF), polymethylmethacrylate (PMMA), calcium phosphate reinforced with titanium mesh (CaP-Ti), polyetheretherketone (PEEK), and hydroxyapatite (HA). The study included 139 patients treated between 2016 and 2022, with a follow-up until the end of 2023.
Key Findings:
- Surgical site infection was the most common complication (13.7%), with PEEK implants having the highest rate (28.6%), followed by ABF (20%).
- Explantation rates were highest for PEEK (25.7%) and ABF (24.0%).
- Neither longer surgical time nor anticoagulation therapy was significantly related to higher infection rates.
- Ventriculoperitoneal shunt implantation prior to CP did not significantly affect complication rates.
- Perioperative lumbar drainage was protective against the need for explantation (p = 0.035).
Conclusions:
The study suggests that the type of implant material significantly affects postoperative infection rates, with PEEK and ABF posing higher risks. Materials like CaP-Ti may offer advantages due to better biocompatibility. The findings highlight the need for further prospective studies to determine the optimal implant material for CP after DHC.
Importance:
This research contributes to the ongoing discussion about the best materials for cranial reconstruction, providing evidence that could lead to improved patient outcomes by reducing the risk of postoperative complications.
