Cranioplasty is a commonly performed procedure following decompressive craniectomy. The patients are usually young earning persons and increasing cost of treatment is difficult to bear especially in low and middle income countries. A variety of options are available for cranioplasty ranging from autologus bone graft to xenograft and synthetic materials. Presently the autologous cryopreserved or subcutaneously preserved bone graft is considered as the preferred choice, but it has the drawbacks of bone resorption and infection. Custom made titanium implants and polyetheretherketone implants, which are manufactured using 3D printing technologies, are also being used. However, their use is limited because of high cost and lack of availability of these technologies in the developing world, which have the maximum number of such cases. The authors present an easy and low cost technique for making a customised cranioplasty implant by polymethylmethacrylate using the craniotomy bone flap of the patient as a template.

Background: The aesthetic reconstruction of disfiguring cranio-facial defects after tumour excision can be quite challenging to the neurosurgeon with limited resources. The choice of cranioplasty implant, intraoperative technicalities and the patients' postoperative appearance are critical considerations in management. There are a number of synthetic materials available for cranioplasty, however, the customised implants are not readily available in our practice setup.

Purpose: Surgical resection with bony margins would be the treatment of choice for tumours with osseous involvement such as meningiomas and metastasis. By developing and designing pre-operative customised 3D modelled implants, the patient can undergo resection of meningioma and repair of bone defect in the same operation. We present a generalisable method for designing pre-operative cranioplasty in patients to repair the bone defect after the resection of tumours.

Background: Autologous bones are traditionally used in surgical reconstruction of skullcap. Since patients' bones are often unavailable or cause of infections, implantable synthetic materials emerged as promising alternative. These can be shaped by different technologies, while 3D printing offers remarkable chances in terms of flexibility, accuracy, cost-saving and customizability.

Rationale: Traumatic brain injury is the most common cause of cranial defects. Cranioplasty is the surgical intervention performed to repair cranial defects. The purpose of a cranioplast is to protect the underlying brain tissues, reduce pain, and improve calvarial contour and symmetry.

Polyether-ether-ketone (PEEK) is believed to be the next-generation biomedical material for orthopaedic implants that may replace metal materials because of its good biocompatibility, appropriate mechanical properties and radiolucency. Currently, some PEEK implants have been used successfully for many years. However, there is no customised PEEK orthopaedic implant made by additive manufacturing licensed for the market, although clinical trials have been increasingly reported.
