Modeling of scaphocephaly using superelastic titanium-nickel rings: a preliminary report.
As long as resection of sagittal suture eliminates craniostenosis it leads to desired cranium broadening and shortening solely in the case of children under six months of age. In the majority of cases, especially in older children, boat-shaped cranium remains rather unchanged and its effective modeling requires extensive dissection and osteotomy of the whole cranium vault (e.g., frontal, occipital and parietal bones). Lauritzen's method is an alternative solution. It consists of distraction of cranium vault bones with the aid of steel springs. In order to simplify and improve the efficacy of treatment since 2002, the authors originated the application of titanium-nickel rings to model the cranium. After the sparing excision of cranium vault sutures in the shape of letter "H" the compressed ring is given in the sagittal axis oval shape and in this form it is fixed to osseous margins. The ring's expansion at the same time broadens and shortens the cranium vault. Material was analyzed from 7 children (range, 9 months to 4 years of age), who were treated in the years 2002-2006 because of sagittal craniostenosis. Observations made so far and good treatment results indicate purposefulness of discussed treatment continuation.
