The removal of cranial springs used in the treatment of scaphocephaly: A minimal access approach.

The treatment of non-syndromic scaphocephaly with spring-activated cranioplasty offers acceptable outcomes with the potential for reduced surgical morbidity when compared with cranial vault remodelling procedures. A disadvantage of this technique is the need for a second operative intervention to remove the implanted devices. There are many descriptions of the surgical technique for performing spring-activated cranioplasty available in the literature; however, little is documented regarding the procedures used for device removal. The published accounts of spring removal demonstrate a wide range of approaches, from the reopening and dissection of the entire previous surgical field, to attempts to limit the incisions and dissection. In this study we describe our technique for the minimally invasive removal of cranial springs used in the treatment of scaphocephaly. Our technique focuses on minimal soft tissue disruption and uses a Kirschner wire cutter to divide the spring at its mid-point so as to relieve any residual internal forces acting on the footplates.
