Removal of a large cranial tumour and reconstruction of the consequent bone defect in the same surgical setting is an ordinary procedure. A custom-made hydroxyapatite ceramic reconstruction of a cranial bone defect is a modern option that currently needs a preoperative stage of studying the bone defect and designing the implant. Consequently, if a reconstructive hydroxyapatite-based procedure after a cranial tumour resection is the aim, a two-stage surgery is necessary. The authors investigated the possibility of performing this procedure in a one-step surgery by the use of a neuronavigation system.
Cranial implants are used as a substitute for parts of cranial bones that lost its function due to trauma or disease. An important factor, that influences function of the cranial implant structure, is its mechanical behavior.
This thesis briefly summarizes current knowledge in the field of cranial defect reconstruction and provides comparison of different types of materials and implant wall shapes, based on stress-strain analysis of Computer Tomography based neurocranial model with placed implant and loaded by intracranial pressure and external load.

N owadays , cranioplasty is used worldwide in all neurosurgical departments. The success of implantation depends on a variety of factors, such as the size and location of cranioplasty, as well as the patient's condition, the material used, and the implantation time. In the worst cases, the consequences range from infections and lengthy hospitalization to implant loss and even mortality. The impact of the choice of the surgeon on the success of intervention can only be evaluated in a prospective study. The idea of collaboration between maxillofacial and neurosurgical specialists, as practiced for example in the Benelux countries, is an interesting approach, especially when it comes to difficult wound conditions or repetitive interventions on the same patient.
Reconstruction of cranial defect is commonly performed in neurosurgical operations. Many materials have been employed for repairing cranial defects. In this paper, materials used for cranioplasty, including autografts, allografts, and synthetic biomaterials are comprehensively reviewed. This paper also gives future perspective of the materials and development trend of manufacturing process for cranioplasty implants.

Correspondence Address : Dr. Custom-made cranial implants facilitate the surgical reconstruction of destructive pathologies of the skull or extensive demolitive skull surgery. Customized cranioplasty allows for an immediate restoration of the functional integrity of the cranial defect restitutio ad integrum , with excellent functional and esthetic outcome and a quick, safe, and simple procedure.
Custom implants for the reconstruction of craniofacial defects have gained importance due to better performance over their generic counterparts. This is due to the precise adaptation to the region of implantation, reduced surgical times and better cosmesis.
