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.

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.

Custom made bioceramic implants in complex and large cranial reconstruction: A two-year follow-up

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. The impact on the wound-healing process can also only be evaluated by means of a prospective survey. Intense debate surrounds the choice of the most suitable material for each patient.

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. In this context, bioceramics like hydroxyapatite HA claim high biocompatibility and bone-binding capability. The osteoconductive properties of the HA have been reported in animal models and humans. The purpose of this study is to demonstrate with radiological and histological examination and how HA prosthesis may integrate after their implantation showing data related to five patients that needed primary HA cranial reconstruction with secondary removal after few years.

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.

Cranioplasty using custom-made hydroxyapatite versus titanium: a randomized clinical trial

The purpose of this study is to evaluate the intra- and post-operative performance and safety of direct three dimensional printing 3DP porous polyethylene implants in cranial reconstruction. Prefabricated porous polyethylene implants were prepared by direct 3DP, and cranioplasty implantation was performed. No complications after surgery were encountered.

INTRODUCTION

 - Он поднял беретту.  - Ты найдешь терминал Хейла, а я тебя прикрою. Сьюзан была отвратительна даже мысль об. - Разве нельзя дождаться звонка Дэвида о той копии, что была у Танкадо. Стратмор покачал головой. - Чем быстрее мы внесем изменение в программу, тем легче будет все остальное. У нас нет гарантий, что Дэвид найдет вторую копию.

 Читайте медленно и точно! - приказал Джабба.  - Одна неточность, и все мы погибли. Фонтейн сурово взглянул на. Уж о чем о чем, а о стрессовых ситуациях директор знал. Он был уверен, что чрезмерный нажим не приведет ни к чему хорошему. - Расслабьтесь, мистер Беккер.

Оглядывая свой роскошно меблированный кабинет, он думал о том, что достиг потолка в структуре АНБ. Его кабинет находился на девятом этаже - в так называемом Коридоре красного дерева. Кабинет номер 9А197. Директорские апартаменты. В этот субботний вечер в Коридоре красного дерева было пусто, все служащие давно разошлись по домам, чтобы предаться излюбленным развлечениям влиятельных людей. Хотя Бринкерхофф всегда мечтал о настоящей карьере в агентстве, он вынужден был довольствоваться положением личного помощника - бюрократическим тупиком, в который его загнала политическая крысиная возня.

Еще одна игра слов мистера Танкадо: разница означает результат вычитания. - Верно! - сказал Беккер с экрана.  - Может быть, у этих элементов разное число протонов или чего-то. Если вычесть… - Он прав, - сказал Джабба, повернувшись к Соши.

 Что же тогда случилось? - спросил Фонтейн.

Currently different biomaterials are available for cranial reconstruction including titanium, acrylic mesh and different types of calcium phosphate-.
