title: Delayed iliac abscess as an unusual complication of an iliac bone graft in an orthognathic case.
abstract: The reconstruction of large maxillofacial defects generally requires harvesting bone from extra-oral sites. The main source of autogenous bone is the iliac crest. This donor site is used to obtain bone for augmentation in orthopaedic surgery, neurosurgery, and oral and maxillofacial surgery, where the main indications are secondary and tertiary osteoplasty in patients with cleft-lip and palate, reconstruction of bony defects after operations for tumours, and augmentation of severe atrophy of the alveolar crest in preprosthetic surgery. A review of the literature on complications following bone harvesting from the anterior iliac crest reveals persistent pain, nerve injury, haemorrhage, limping, persistent gait abnormalities, conspicuous scarring, bone contour alteration, infection, fracture, meralgia paraesthetica, peritonitis, and herniation. The authors report an unusual complication: a huge iliac abscess that appeared 4 years after bimaxillary surgery involving iliac bone grafts.
