Cranioplasty in children
Insights
Autologous bone flaps are effective for pediatric cranioplasty, showing low complication rates. While split calvarial grafts and allografts had no complications, autologous bone is preferred for its biological advantages.
Area of Science:
- Pediatric Neurosurgery
- Craniofacial Surgery
- Biomaterials in Medicine
Background:
- Cranioplasty is a reconstructive procedure to repair skull defects.
- Material selection for pediatric cranioplasty impacts outcomes and complications.
- Various autologous and synthetic materials are used for skull reconstruction.
Purpose of the Study:
- To evaluate the outcomes and complications of different cranioplasty implant materials in pediatric patients.
- To compare the success rates of autologous bone grafts versus synthetic materials.
- To identify factors influencing complication rates in pediatric cranioplasty.
Main Methods:
- Retrospective review of 28 cranioplasties in 24 children (1994-2001).
- Indications included trauma, tumor, infection, cysts, and post-reconstruction defects.
- Materials assessed: autologous bone flap, split calvarial graft, acrylic, and titanium.
Main Results:
- Overall morbidity was 18% (5 patients), with an infection rate of 10%.
- Autologous bone flaps had a low infection rate, particularly when single flaps were used.
- Split calvarial grafts, acrylic, and titanium implants showed no complications.
Conclusions:
- Autologous bone grafts are a preferred material for pediatric cranioplasty due to biological advantages.
- Split calvarial grafts and allografts demonstrated a complication-free profile.
- Even infected autologous bone flaps can be successfully re-implanted.
Objective:
The objective was to assess the outcome and complications associated with different cranioplasty implant materials in children.
Materials And Methods:
A retrospective review was conducted of 28 consecutive cranioplasties carried out on 24 children between 1994 and 2001 (age range, 9 months to 15 years; minimum follow-up 18 months). The indications were: defect from previous craniectomy for trauma, tumour, infection or evacuation of haematoma (n=21), intradiploic dermoid cysts (n=2), growing fractures (n=4) and residual bony defect following craniofacial reconstruction (n=1). The materials used were: patient's craniectomised bone flap (n=16), split calvarial graft (n=8), acrylic (n=3) and titanium (n=1). All patients were assessed for bony fixation, cosmesis, wound healing and flap infection.
Results:
There was no mortality and 18% morbidity (n=5: 3 infected flaps, 1 sterile wound dehiscence and 1 sterile wound discharge; overall infection rate 10%). Out of the 14 patients who had their own craniectomised bone flaps implanted initially, 3 became infected (2 in patients with bilateral defects) necessitating flap removal. Two of these were successfully re-implanted. No donor or recipient bone flap complications were seen in the 8 split calvarial grafts, wound discharge was seen in 1, requiring wound toilet. No complications were seen with acrylic or titanium cranioplasties.
Conclusion:
In this series, the use of the patients' own craniectomised flap had a low infection rate, and was mainly seen in patients who had bilateral flaps re-implanted soon after removal. There were no complications arising from the use of split calvarial and allograft material. Use of autologous implant material should be preferred whenever possible due to obvious resource and biological advantages, and can even be re-implanted if infected.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
