Use of Neuronavigation in Suturectomy for Craniosynostosis.

Smaller operative exposures associated with suturectomy for craniosynostosis may result in difficulties visualizing the prematurely fused suture during surgery. The authors report cases of suturectomy for lambdoid and metopic craniosynostosis in which neuronavigation or frameless stereotaxy was used to assist with incision planning and intraoperative localization of the fused suture. In both cases, neuronavigation integrated easily and safely into established workflows and was associated with complete suture release. To our knowledge, this is the first report of applying this noninvasive technology, which does not require cranial pinning or rigid fixation, to suturectomy, and the authors demonstrate its use as an adjunct, especially for surgeons beginning in practice. Larger studies are needed to determine if neuronavigation in suturectomy is associated with a clinically significant reduction in blood loss or operative time or an increase in the rate of complete suturectomy.
