Abstract

Background: The purpose of this study was to evaluate the outcome and complication rates of different cranioplastic procedures. Patients and methods: This study retrospectively reviewed 242 consecutive patients who underwent cranioplasty. The indications for craniectomy, the timing and materials employed for the cranial repair procedures were analysed in all patients as well as their early and long-term results. The immediate patient's outcome after cranioplasty was assessed by reviewing medical records and the late outcome was evaluated with a telephone questionnaire. The patients were divided into three groups depending on the timing of cranioplasty [ultra early group (until 6 weeks), early group (7-12 weeks) and delayed group (after 13 weeks following craniectomy)]. Results: The ultra early cranioplasty in the form of reimplantation of the patient's own skull flap led to a rapid improvement of the patient's neurological function and late outcome. The analysis of the registered postoperative complications revealed that there were no significant differences between the groups examined. Conclusion: This study found that ultra early cranioplasty by reimplanting the patient's own previously removed and frozen skull bone was a safe and successful strategy. [ABSTRACT FROM AUTHOR]

Abstract

Titan ist ein etabliertes Knochenersatzmaterial fur die Versorgung komplexer Schadeldefekte mittels individuell geplanter CAD/CAM-Implantate. Zur Verbesserung der durch Patientenkontrollstudien evaluierten thermischen und psychischen Belastungsfaktoren wurde in der vorliegenden Studie ein gradiertes Kompositmaterial aus Polymeren und Calciumphosphat bzw. Calciumcarbonat entwickelt. Biokompatibilitatsuntersuchungen auf Basis des ISO-Standards 10993-5 erlaubten zunachst die Auswahl geeigneter Materialien sowie nachfolgend die Feststellung der verbesserten pH-Charakteristika der Kompositmaterialien gegenuber den reinen Polymeren. Fur die geometrisch korrekte Herstellung der Implantate aus Kompositmaterialien wurden zwei unterschiedliche Verarbeitungsmethoden gewahlt und kombiniert. Diese Implantate konnten bereits durch in-vivo Versuche an einem eigens entwickelten Grostiermodell getestet werden und zeigten post mortem bei einem Nachbeobachtungszeitraum von zwei Monaten keine histologischen Reaktionen auserhalb der Norm und eine beginnende Knochenbildung. Klinisch ergaben sich bei den lebenden Schafen auch nach einem Zeitraum von bisher 11 Monaten keinerlei Komplikationen. Individual Implants of Biodegradable Composites for the Reconstruction of Skull Defects For the reconstruction of complex skull defects with individual prefabricated CAD/CAM-implants titanium is well established as a bone substitution material. In this study, a biodegradable composite material from polyesters and calcium phosphate was developed to reduce thermal and psychic stress factors, which were found in previous patient control studies. Biocompatibility tests based on the ISO-standard 10993-5 allowed the choice of suitable materials and showed much better pH-characteristics of the composites in comparison to the pure polymers. For the geometrically precise production of the implants, two different operating procedures (hot pressing and gas flushing) were combined. These implants have already been tested in in-vivo studies in sheep. Two months after implantation, post mortem there was no abnormal histological reaction but signs of beginning bone replacement. Nine months after operation there were no clinical complications in the living animals.
