SummaryFacial bipartition is amongst the most radical craniofacial surgery undertaken but is performed rarely. There is little published information on its anaesthetic management. We undertook a retrospective case-note review of 22 consecutive patients undergoing bipartition surgery by the same surgical team in one centre in the period 1993-2001. There were incomplete data for two cases and these were therefore excluded. Patients were aged 2 months to 19 years. Conditions treated were facial cleft (n = 5), frontonasal dysplasia (n = 7) and facial dysostosis (n = 8). Intra-operative complications included major haemorrhage (n = 4), bradycardia (n = 3) and unintentional tracheal extubation (n = 1). There were no peri-operative deaths. All patients required intra-operative blood transfusion and 15% of them had a postoperative haemoglobin concentration > 115% of their pre-operative value. In this series, four patients required postoperative lung ventilation for a median duration of 3 days. Infants < 14 months old were significantly more likely to receive a massive blood transfusion (p = 0.0002), to have an excessively high postoperative haematocrit (p = 0.008) and to require postoperative lung ventilation (p = 0.0002) compared with older patients. We conclude that patients in this age group have a significantly increased risk of postoperative complications.
