Complications related to midfacial fractures: operative versus non-surgical treatment.

The treatment of midfacial fractures depends on the dislocation of the fracture and patient-related limitations. Surgical treatment risks iatrogenic complications. In 740 patients with midfacial fractures, the age, sex, fracture type, concomitant injuries, cause of accident and the decision to use operative or non-surgical treatment were recorded. Follow-up was performed 6 and 12 months after the injury. In 41% the fractures were isolated; they were multiple in 59%. Initially, hypaesthesia of the infraorbital nerve was present in 10% of the single and 16% of the multiple fracture patients. Surgical treatment was performed in 57% of the single and in 75% of the multiple fracture patients. Women underwent surgical treatment considerably less frequently than men. After 6 and 12 months, significantly more complications were present in the surgically treated cohort. Nerve disturbances and 'meteorosensitivity' were most prominent. These results, together with previous findings, indicate that there is a need for prospective clinical investigations that fulfil the criteria of evidence-based medicine to generate guidelines for decision making in trauma surgery. In the meantime, the decision to use surgical treatment for midfacial fractures has to be made carefully.
