Introduction. Autogenous bone is commonly used in pre-implant bone reconstructions. Five harvesting sites are frequently used: mandibular symphysis and ramus, iliac crest, calvaria and tibia. One of the deciding criterions among these sites is the donor site morbidity. The purpose of our work was to analyze the intra-and postoperative complications that may occur on the different donor sites.Material and methods. An automatic and manual search on Medline covering the period 1990-2015 was made. Human studies, in English or French language, detailing the complications linked to bone harvest done for pre-implant surgery were included.Results. Eighty-three clinical trials or case reports were analyzed. Iliac crest, mandibular symphysis and ramus donor sites were afflicted with the highest pain scores and sensory disturbances. Iliac and tibial bone harvests were complicated by walk disturbances in the first weeks. Some rare neurological complications have been reported after calvarial bone harvest.Discussion. Although commonly used, iliac crest bone harvest is responsible for significant morbidity. Calvarial harvest is related to the lowest morbidity. It has to be performed by an experienced team in order to reduce the risk of neurologic injury. Regarding intraoral donor sites, mandibular symphysis becomes less popular. Mandibular ramus harvest has the lowest complication rate and is well accepted by patients. (C) 2016 Elsevier Masson SAS. All rights reserved.
Introduction. Clinical presentation of Eagle syndrome (ES) is very variable and non-specific, making its diagnosis difficult. It is usually limited to pain. Transient neurological manifestations are exceptional. We report one case in which the diagnosis of ES has been made based on neurological events occurring during left anterolateral head bending, without pain.Observation. A 47-year-old man presented with transient neurological events progressing since two years, half-right body paresthesia and reduced field of vision on the left side type, triggered by left anterolateral head flexion and regressive in neutral position. Transcranial Doppler and CT angiography of the supra-aortic trunks were performed in neutral position and in right and left head rotation that showed a disruption of the left sylvian flow and an extrinsic compression of the left internal carotid artery, due to a musculoskeletal impediment involving the lower end of the temporal styloid process. Complete recovering was achieved after surgical resection of this process. A control CT angiography confirmed the cessation of the compression.Discussion. ES has non-specific and highly variable clinical manifestations making diagnosis difficult or leading to misdiagnosis. ES should be considered in any transient neurological deficit, especially when occurring during head rotation. Treatment relies on surgical resection of the excessively long styloid process.
