Triple square extended osteotomies for treatment of scaphocephaly (Renier's "H" technique modification).

Scaphocephaly is the most common single suture craniosynostosis. Surgical technique has evolved from simple strip craniectomy over π-procedures and vertex craniectomies to extensive cranial remodeling which is preferred procedure nowadays. The purpose of this paper is to present our modification of Renier's standard "H" technique and its preliminary results in detail. Eleven patients with scaphocephaly were surgically treated from January 2011 until January 2014. Only children with isolated sagittal synostosis were included in the study. Our modified Renier's technique reduces the possibility of lesion of superior sagittal sinus, dividing parietal bone in three bone fragments, thus achieving shortening of the scull in AP diameter without detaching the bone from the superior sagittal sinus. The possibility for potential secondary stenosis is minimized using extended V-shaped osteotomies with rounding of the bone edges, as well as making wide neocoronal and neolambdoid sutures. Cosmetic results were estimated as very pleasing immediately after surgery by both the parents and the surgeons in all cases. The majority of patients presented in our study were categorized as Sloan Class 1. Improvement or normalization of the cranial index was accomplished in all patients. No revision surgeries were required during the follow-up. Triple square extended osteotomies technique is a fast, simple, and efficient surgical option for children with sagittal synostosis and can be safely applied in the first months of life in children even under weight of 6 kilos. Preliminary results are encouraging and deserve a longer follow-up and comparative surgical analysis to verify its usefulness in the future.
