Background: Treatment of intraoral malignant tumors often leads to continuity defects of the mandible. Whereas the use of free vascularised flaps has shortcomings regarding donor site morbidity and a worse-fitting bone geometry, the nonvascularized iliac crest graft could be an alternative option. The purpose of this study was to describe the treatment outcome with nonvascularized iliac crest grafts over a 10-year period and to determine possible limitations of their use., Patients and Methods: Eighty-four patients with bicortical nonvascularized iliac crest grafts for mandibular reconstruction were examined at least one year after reconstruction. Patients' records and the radiological and/or surgical data were analyzed., Results: Sixty-three patients (75%) showed complete healing, in 20 patients the treatment was not successful and in one patient the treatment result was unclear. Interestingly, comparing the successfully and the unsuccessfully treated patients, only the irradiation dose played a crucial role. Neither defect length nor defect localisation, nor time interval between resection and reconstruction were statistically significant parameters in graft success. Comparing only patients with malignancies, the non-irradiated patients had a higher success rate (77.3%)., Conclusion: The nonvaslcularized iliac crest graft seems to be a reasonably reliable treatment option for reconstruction of mandibular defects up to about 5-6 cm in size. Radiotherapy is a strong confounder reducing the success rate. Necessary constraints are sufficient soft tissue conditions. However, primary reconstruction by free flaps (e.g. fibula flap) has a higher success rate in literature and should be preferred whenever possible.

Background: Bleeding disorders (BD) can cause significant problems during or after surgical procedures of the oral cavity. The aim of this study was to explore the risk of bleeding following oral surgery in patients with BD., Patients and Methods: The medical records of all BD patients referred to the department of cranio- and maxillofacial surgery were reviewed., Results: Ninety-five patients (26 inherent BD, 69 taking antithrombotic drugs) were reviewed for this study. Interestingly, patients taking oral anticoagulants presented more bleeding complications than patients with inherent BD. During simple tooth extraction procedures, patients taking antithrombotic drugs had a higher risk of bleeding than patients with inherent BD., Conclusion: The currently available treatment protocols for surgical treatment of dental patients with inherent BD suffice. However, our data indicates that there is still a need for clear guidelines for the treatment of patients taking antithrombotic drugs, especially phenprocoumon.
