BACKGROUND: Piezosurgery (PS) has gained increasing dispersion in neurosurgery. In pediatric neurosurgery, the experience is limited to craniosynostosis surgery. The present study assesses PS in the pediatric population, also considering outcomes and complications in cranial and spinal procedures. METHODS: All consecutive craniotomies and laminotomies, performed with PS (group A) or conventional osteotomes (group B) in the 2014-2017 period were reviewed. The following variables were analyzed: dural tears, estimated blood loss and need of transfusion, cosmetic outcome (Sloan score), and operative times. A review of the pertinent literature is included. RESULTS: 172 children were enrolled, 90 in group A and 82 in group B. The mean follow-up time was 2.1 years. A statistically significant difference in favor of group A was found about EBL (105 vs. 113 ml) and late outcome (Sloan class A 98.5% vs. 91.5%). PS also reduced the risk of dural tears (1 vs. 7 cases in groups A and B, respectively) and blood transfusion (52% vs. 55.5%) but without statistical significance. The operative times were significantly shorter in group B (13 vs. 23 minutes), although the newer PS plus (PSP) was demonstrated to significantly shorten these times compared with the traditional PS (3.5 vs. 6.5 minutes for orbitotomy and 7.5 vs. 9.5 minutes for hemicraniotomy). CONCLUSIONS: PS is a safe and effective tool that can be specifically recommended for bone splitting and graft, laminotomy, and craniotomy in cosmetically eloquent areas. The limit of operation times can be overcome by a learning curve in neurosurgery and PSP.
