Evaluation of the Safety and Effectiveness of a Medical Device Aimed at Guiding Orbito-naso-frontal Band Surgery, for the Treatment of Craniostenoses

Обзор

Craniostenosis is a congenital disorder caused by early fusion of the cranial sutures between the skull bones, resulting in orbito-naso-frontal deformities. The damage is primarily aesthetic, but intracranial hypertension may also be observed. The treatment of craniostenosis involves surgery, to restore harmonious growth between the skull bones and the brain, and proper development of the latter. There are various surgical techniques for correction, based on remodeling of the upper forehead and the orbito-naso-frontal band (BONF). However, BONF reshaping is difficult to tailor to each individual child. In most cases, the surgeon performs the reshaping "freehand", without a template. The result is therefore subject to the surgeon's experience and judgment. A surgical instrument (template) has been developed to guide the surgeon in the ideal reshaping of the BONF in patients with anterior craniostenosis (anterior plagiocephaly and trigonocephaly), according to each child's specific morphology. The aim of EPBONF research is to evaluate the benefits of using this template on the symmetry and angle of the BONF.

Вмешательства

• Устройство BONFIX system
  The device corresponds to a customized, single-use surgical guide (Class IIa medical device), with a set of different sizes, adapted to the fronto-zygomatic distance (FDZ) measurement, in order to enable better conformation of the orbito-naso-frontal bandeau during surgery for anterior craniostenosis, an ideal conformation that could lead to optimal symmetry and adapted to the morphology of the upper third of infants. The surgeon conforms the orbito-naso-frontal bandeau by adapting the advancem
