Brief summary: 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.


Eligibility criteria: Inclusion Criteria:

* Children with anterior craniostenosis (organic trigonocephaly or anterior plagiocephaly), aged 4 to 24 months
* Procedure performed at Besançon University Hospital
* Written consent from both parents, or from one parent if there is only one, indicating that they have understood the purpose and procedures of the study, and that they agree to their child's participation in the study and to the study's requirements and restrictions.
* Affiliation with a French social security scheme or beneficiary of such a scheme.
* Pre-operative computed tomography scan and cone beam to measure the fronto zygomatic distance and naso-frontal angle in trigonocephaly, and to calculate the frontal process of the zygoma symmetry defect in organic anterior plagiocephaly.

Exclusion Criteria:

* Legal incapacity or limited legal capacity of parent(s)
* Subject is in the exclusion period of another study or is on the "national volunteer list".
