Abducens Nerve Palsy Following Expansion Cranioplasty with Distraction Osteogenesis.

Childhood abducens nerve palsy can occur as a result of trauma, tumour, vasculopathic disease, elevated intracranial pressure, infection, inflammation, and congenital or idiopathic causes. The authors present two cases of unilateral abduction deficit secondary to a recent trans-sutural distraction osteogenesis (TSuDO) operation for craniosynostosis. After distractor removal, the problem resolved spontaneously over 2-4 months in both cases. This is a first reported case of sixth nerve palsy as a complication of TSuDO operation.
