Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Decompressive craniectomy due to craniocerebral trauma, cerebral ischemia and cerebral hemorrhage.
  • Age 18 - 80 years.
  • The first time for cranial repair.
  • unilateral skull defect.
  • Compliant with recommended decompressive bone flap surgery and autogenous decompressive bone flap after bone flap collection
  • signed the informed consent.

You may not qualify if:

  • Poor healing of skin flap (active infection, non-healing, necrosis, sinus, thin or poor blood supply, etc.).
  • Fracture of bone flap ≥2 pieces, partial open fracture
  • Intracranial infection before operation.
  • Severe bone metabolic diseases.
  • Long-term use of immunosuppressants.

Masking Details
The study was open-label, endpoint-blinded, i.e. only the patients themselves and the treating physicians knew the randomization assignment results, baseline was evaluated by investigators who did not know the actual patient assignment, and primary endpoint visits were conducted by trained third parties who did not know what treatment the patients received.
