Problems with lateral canthal advancement.

The technique of lateral canthal advancement for the treatment of premature coronal craniosynostoses has been employed in 12 cases. In patients with high intracranial pressure aesthetic problems after the operation were observed. The frontolateral area did not reossify and the brain bulged forward. For secondary correction in these cases the bilateral advancement of Marchac and Renier was used. A sufficient increase of intracranial volume could be achieved by complete osteotomy of the skull base. The bone segments were stabilized by miniplate osteosynthesis. The results were thereby improved.
