Randomized Controlled Trial Clinical TrialPain following iliac crest bone grafting of alveolar clefts.
The purpose of this study was to investigate pain following iliac crest bone grafting of alveolar clefts. The study involved 34 consecutive patients requiring secondary alveolar bone grafting. The study population consisted of 21 males and 13 females with a mean age of 11 years (SD = 3.4). ⋯ No long-term donor site morbidity was observed. Our results suggest that pain following iliac crest bone grafting of alveolar clefts is not severe and is readily alleviated with small quantities of analgesic drugs. It would appear that short-term morbidity following these procedures is frequently overstated and is in itself not a valid reason to change to calvarial or mandibular donor sites.

Case ReportsReconstruction of craniofacial bone defects with individual alloplastic implants based on CAD/CAM-manipulated CT-data.
Reconstruction of craniofacial bone defects by intraoperative modelling of autogenous or alloplastic materials may cause undesirable results concerning the implant shape or the long-term maintenance of this shape. Furthermore, the use of alloplastic materials to be modelled intraoperatively may result in an inflammatory tissue response. Therefore the question is raised whether CAD/CAM-techniques may be used for the pre-operative geometric modelling of the implant based on helical computed tomography data. ⋯ The precise and individual fit of the implant results from generating its margins by the borders of the defect, whereas the implant surface is generated by the geometry of the non-affected neighbouring bone contours. The implant data run a numerically controlled milling machine to fabricate the individual implant. The reconstruction of post-traumatic defects of the forehead, of post-surgical temporal defects after intracranial haemorrhage, and of a parieto-occipital defect due to ablative tumour surgery are presented as the first clinical experiences of this new method.

Clinical investigation into the incidence of direct damage to the lingual nerve caused by local anaesthesia.
The aim of this study was to investigate the amount of damage to the lingual nerve by mandibular block anaesthesia alone. For this purpose the records of 12,104 patients in whom mandibular block anaesthesia was administered without any type of surgery were reviewed. ⋯ In 17 out of these 18 patients the tongue sensation recovered after a period of 6 months. Only in one patient (0.008%) was there a slight sensory diminution of the tongue, even after one year.
