Cranioplasty

Cranioplasty is a surgical procedure aimed at restoring the integrity and anatomical shape of the skull. It is performed using various materials to replace bone defects that develop after trauma, neurosurgical operations, or congenital anomalies. The procedure not only reconstructs the skull structure but also protects the brain, improves appearance, and in some cases contributes to the recovery of neurological functions.

Indications for cranioplasty

1. Traumatic skull defects. Consequences of traumatic brain injury. Defects after decompressive craniectomy.
2. Postoperative defects. Removal of tumors or other pathological lesions involving cranial bone loss.
3. Congenital anomalies. Craniosynostosis and other skull malformations.
4. Infectious complications. Reconstruction after cranial osteomyelitis.
5. Aesthetic indications. Correction of significant skull deformities.
6. Functional indications. Improvement of cerebral blood flow, cerebrospinal fluid dynamics, and intracranial pressure regulation.

Preoperative preparation

1. Imaging studies. CT and MRI of the brain. Cerebral angiography when indicated.
2. Laboratory tests. Complete blood count, biochemical analysis, and coagulation profile.
3. Preoperative consultations with a neurologist, neurosurgeon, and anesthesiologist.
4. Selection of implant material. Individual 3D modeling for custom-made implants.

Materials used for cranioplasty

1. Autologous bone (patient’s own bone). Advantages include excellent biocompatibility; limitations include possible insufficiency of available bone tissue.
2. Alloplastic (synthetic) materials. Titanium plates: lightweight, strong, and reliable fixation. Polymers (PMMA, polyethylene): suitable for large defects with good cosmetic results. Ceramics: highly biocompatible materials with bone-like properties. Patient-specific 3D implants manufactured according to individual anatomical data.

Surgical procedure

1. Anesthesia. The operation is performed under general anesthesia.
2. Access to the defect. Incision is made in the area of the defect or previous surgical site.
3. Preparation of the defect zone. Removal of scar tissue and careful preparation of surrounding structures.
4. Implant placement. The implant is fixed using screws, plates, or surgical adhesives.
5. Wound closure. Layered suturing with restoration of skin integrity.

Postoperative period

1. In-hospital monitoring. Hospital stay usually lasts 5–7 days with neurological and wound-healing control.
2. Medication therapy. Antibiotics for infection prevention and analgesics for pain control.
3. Recommendations. Avoid physical exertion for 4–6 weeks. Scheduled follow-up visits.
4. Imaging follow-up. CT scan or X-ray after 1–3 months to assess implant position.

Advantages of cranioplasty

1. Restoration of the protective function of the skull.
2. Cosmetic improvement and normalization of head contour.
3. Potential neurological improvement through normalization of cerebrospinal fluid circulation and intracranial pressure.
4. Long-term outcome. Modern implants are designed for durable, long-lasting use.

Possible complications

1. Infection. Risk is minimized with appropriate antibiotic therapy.
2. Implant rejection. Rare and usually related to individual intolerance.
3. Hematoma or seroma. Accumulation of blood or fluid in the surgical area.
4. Residual cosmetic defects. Incomplete correction of skull contour.

Prognosis

• Successful recovery. Most patients achieve stable functional and aesthetic results without complications.
• Durable effect. Implants maintain stable positioning for many years.
• Recurrence. Unlikely when proper surgical technique and postoperative recommendations are followed.

Cranioplasty in Belarus is a highly effective neurosurgical procedure aimed at restoring skull integrity and function. The use of modern materials and advanced technologies ensures high precision, minimal complication risk, and long-term results. Timely cranioplasty improves not only appearance but also the overall quality of life.
