[Complications of orbito-frontobasal fractures].

Complications of fronto-basal trauma can, as a function of their severity, be divided into three classes: life-threatening situations, functional complications and cosmetic defects or facial deformities. They find their origin in the type of trauma, the extent of the lesions of bone and soft tissues, as well as in their timely management and quality of treatment. The etiology of the most common complications and their significance are covered with accent on inadequate primary treatment, insufficient repair of dural lesions, inadequate drainage, unstable osteosynthesis, insufficient treatment of scalp- and frontal defects, and finally the lack of antibiotic prophylaxis. The major complications of frontobasal trauma such as chronic cerebral spinal fluid fistulae and pneumocephalus are reviewed. Attention is also given to the importance of adequate drainage in cases of chronic ethmoidofrontal sinusitis, and on the treatment of osteomyelitis and sinus cysts. The therapeutic possibilities in patients with tissue deficits, i.e. reconstruction of frontal skull defects using autologous hip and rib material, as well as split calvarial bone grafts is discussed.
