Cranioplasty
Cranioplasty is a neurosurgical procedure that repairs a skull defect — created after a previous decompressive craniectomy or trauma — by replacing or reconstructing the missing bone with the original bone flap or a custom prosthetic implant, restoring skull integrity, protecting the brain, and improving neurological function and quality of life.
Overview
Cranioplasty is performed to restore the normal anatomy and protective function of the skull following a craniectomy, in which the bone was removed as part of emergency decompression for brain swelling, haematoma, or infection. Beyond the obvious cosmetic benefit of restoring head contour, cranioplasty has well-documented neurological benefits — restoring normal cerebral blood flow dynamics and CSF circulation, improving the brain's metabolic activity, and frequently resulting in measurable neurological and cognitive improvement in patients who have experienced the syndrome of the trephined (neurological deterioration from a skull defect). The procedure uses either the patient's own preserved bone flap or a custom-manufactured prosthetic implant.
Types of Cranioplasty
Cranioplasty can be performed using several materials and techniques depending on the size of the defect, the condition of the preserved bone, and patient factors.
- Autologous Bone Flap Cranioplasty (using the patient's own preserved bone — preferred if intact)
- Titanium Mesh Cranioplasty (lightweight, strong metal mesh moulded to the defect shape)
- Custom PEEK Implant Cranioplasty (polyetheretherketone — computer-designed custom implant)
- Hydroxyapatite Cement Cranioplasty (calcium-based bone substitute for smaller defects)
- 3D-Printed Custom Implant Cranioplasty (manufactured from CT scan data for perfect fit)
Risk Factors for Complications After Cranioplasty
Cranioplasty carries specific complication risks related to the prior history of cranial surgery, the duration of the skull defect, and the patient's overall medical condition.
- Previous wound infection or osteomyelitis contaminating the cranioplasty site
- Long interval between craniectomy and cranioplasty increasing scalp tissue contracture
- Previous irradiation to the scalp reducing tissue vascularity and healing capacity
- Diabetes mellitus impairing wound healing and increasing infection risk
- Immunosuppression from medication or medical condition
- Large skull defect requiring extensive reconstruction with prosthetic material
Indications and Symptoms for Cranioplasty
These symptoms and clinical findings indicate the need for cranioplasty to restore skull integrity and neurological function after a previous craniectomy.
- Visible and palpable skull defect causing cosmetic distress and psychological impact
- Syndrome of the trephined — neurological deterioration, headache, and fatigue from skull defect
- Brain pulsation visible under the scalp at the craniectomy site
- Abnormal CSF dynamics causing cognitive and functional impairment
- Increased seizure frequency associated with the skull defect
- Neurological plateau followed by documented improvement after cranioplasty
- CT evidence of midline shift or ventricular asymmetry related to the craniectomy defect
- Patient and family readiness for the procedure after adequate recovery from the original injury

Clinical Features
The technology, techniques and clinical approach behind our cranioplasty.
Custom implant manufactured from CT data for a perfect anatomical fit to the skull defect
Patient's own preserved bone flap used when intact — the most biologically compatible option
Titanium, PEEK, or hydroxyapatite implant options available for each individual patient
Meticulous dural adhesion release performed before implant positioning for safe placement
Multiple-point titanium fixation ensures permanent implant stability and security
Preparation Instructions
- Complete a CT head and CT skull reconstruction to plan implant design and confirm brain readiness
- Blood tests including CBC, coagulation, blood group, and inflammatory markers (CRP, ESR) are essential
- Any active infection must be fully treated and resolved before cranioplasty
- Stop anticoagulants under haematology supervision 5 to 7 days before surgery
- Fast for 8 to 10 hours before the procedure
- Confirm the prosthetic implant or preserved bone flap is available before the day of surgery
- Arrange home support for 3 to 4 weeks post-discharge
- Attend pre-operative neurosurgical consent consultation to discuss implant options and expected outcomes
The Procedure
Step-by-step guide to what you can expect during your cranioplasty procedure.
Timing Assessment and Implant Planning
Your neurosurgeon assesses your recovery progress, brain re-expansion on CT imaging, inflammatory markers, and scalp condition to confirm you are ready for cranioplasty. For custom implants, a CT skull reconstruction is obtained and the implant is manufactured to exactly fit your skull defect before your admission date.
Scalp Preparation and Anaesthesia
General anaesthesia is administered and the scalp over the skull defect is prepared in a sterile manner. The previous scar is carefully excised and the scalp flaps are elevated to expose the full extent of the skull defect, freeing the dura from any adherent scar tissue with patient dissection.
Dural Adhesion Release
Scar tissue binding the outer brain covering (dura) to the overlying scalp is carefully and patiently divided. This step requires great care to protect the underlying brain and dural sinuses. Freeing the dura creates the space needed to position the implant correctly against a flat cranial surface.
Implant or Bone Flap Positioning
The custom titanium, PEEK, or hydroxyapatite implant — or the patient's own previously preserved bone flap — is positioned precisely within the skull defect and assessed for fit, contour, and symmetry from all angles. Minor adjustments are made to achieve the most natural head contour restoration possible.
Secure Implant Fixation
The implant is secured to the surrounding bone edges using small titanium screws and fixation plates positioned at multiple points around the defect perimeter. Each fixation point is placed carefully to ensure the implant cannot move or loosen over time while causing minimal additional tissue disruption.
Layered Scalp Closure
The scalp flaps are closed in careful anatomical layers over the secured implant, and a drain may be placed for 24 to 48 hours to prevent haematoma or seroma formation. The cosmetic result is assessed before the final skin closure to ensure the best possible symmetric head contour has been achieved.
What to Expect
Cranioplasty is performed under general anaesthesia and takes 2 to 3 hours. The scalp is carefully opened over the skull defect, the scarred dura is dissected free, and the implant or bone flap is precisely fitted and secured with titanium screws and fixation plates. Meticulous scalp closure is performed in layers to ensure excellent wound healing. Most patients are discharged within 3 to 5 days and notice an immediate improvement in headache, energy, and neurological symptoms.
Recovery
After Cranioplasty, protect the repaired skull area from any direct impact or pressure for at least 6 to 8 weeks while the implant integrates and the scalp heals. Keep the scalp wound clean and monitor carefully for any signs of infection — the most serious complication of cranioplasty. Attend all follow-up CT scans and neurosurgical reviews at 6 weeks, 3 months, and 1 year to confirm successful integration. Contact your neurosurgeon immediately for fever, wound breakdown, scalp swelling, or any new neurological deterioration.
