“…11 Various materials are available for the reconstruction of craniofacial defects, ranging from the autogenous bone grafts to titanium meshes, osteoinductive and osteoconductive cements, and other biomaterials. 11,12 All options have advantages and disadvantages, and no single ideal material for this has yet been found. 11 The literature presents several options of polymers for the reconstruction of cranial defects, which present desirable characteristics for reconstructions such as the following: (1) they have suitable resistance for the reconstruction of extensive total defects; (2) they are radiolucent but not ferromagnetic, allowing postoperative control with CT scans and nuclear magnetic resonance imaging (NMRI)/MRI.…”

Nowadays the reconstruction of craniofacial defects can be performed with different kinds of materials, which include the bone and the so-called biomaterials, which have the advantage of not needing a surgical site donor. Among these materials, great attention is given to polymers. In this large group, current attention is focused on the castor oil polymer, since this polymer is biocompatible, low cost, and has adequate strength for reconstruction of the craniomaxillofacial complex. This study aims to report the use of a prosthetic castor oil polymer for reconstruction of extensive defect, caused by a trauma, in the temporoparietal region.

“…Cranioplasty has improved over the past two decades. [ 5 6 7 8 ] In reconstructive surgery, replacing missing structures with those most similar to them are fundamental dogma. In the case of cranioplasty, vascularized bone has the highest similarity to the native calvaria and is therefore our preferred reconstructive material when possible.…”

Background:Anterior cranial bone defects secondary to global war cranial defects pose a unique reconstructive challenge. The objective of this study was to evaluate the outcomes of alloplastic reconstructions of cranial bone with titanium mesh and fat graft after warfare-related cranial trauma.Patients and Methods:Thirty-five patients at the plastic and reconstructive surgery ward of our hospital underwent anterior cranioplasty with titanium mesh with or without fat grafts from lower abdominal wall. Inclusion criteria were anterior cranial bone defect due to warfare injuries, the mean age of these patients was 31 years (range, 23–48 years). Ninety-five percent were male, and 5% were female. Average follow-up was 12 months. Fat grafts were used to help obliterate endocranial dead spaces.Results:Twenty-five patients (71%) had more than 0.5 cm dead space under cranial defects, and we used fat graft under the titanium mesh. The majority groups of patients (80%) were injured as a result of previous explosive device blasts with or without neurosurgical procedures in the past. The average patient age was 31 years, and 95% of patients were male. The mean anterior cranial defect size was 6 cm × 8 cm, and there were no wound infection or flap necrosis after operations.Conclusion:We recommend this procedure (titanium mesh with or without fat graft) for warfare injured cranial defects in secondary anterior cranial reconstructions. Fat grafts eliminates dead space and reduce secondary complications.

“…A customized medical implant and surgical resection template that matches skeletal anatomy can now be accurately designed using the CAD technique. The physical model of the individual implant, template, or skull replica can be produced through 3D printing, rapid tooling (RT), and computer aided manufacturing/computer numerical control (CAM/ CNC) processes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. This paper presents some clinical cases, where virtual models have been used for surgical preparations and 3D printing models for manufacturing of implants.…”

In this paper, we report the benefit of Computer Tomography (CT), reverse engineering (RE) and rapid prototyping (RP) in individual implant production for maxillofacial surgery. The design and fabrication processes includes: a) processing medical image data of a patient's pathologically defective area having a symmetrical part to construct a three-dimensional (3D) digital model; b) forming an image on the defective side, in this step different techniques are applied for individual cases, including mirroring the non-defect side, implant design from other skull CT data; c) implant geometry modeling; d) 3D printing of the skull and implant model; e) surgical planning and prosthesis fitting; f ) casting of a custom-fit titanium implant. Results show that the CAD method can reconstruct the defect after surgical resection. The 3D printing technique provides an accurate tool for preoperative, surgical simulation. The design and manufacturing time of the bone implant has thus been significantly reduced using the CAD method.
