Metopic synostosis diagnosis

Males are affected more commonly in a ratio of male to female of 3:1. Metopic synostosis is associated with a low level of longer term developmental delay, which seems unrelated to the degree of the deformity or whether surgery is performed.

Diagnosis is made by a combination of clinical and radiological assessment, with subsequent referral for multidisciplinary management in a formal craniofacial team.

At the Australian Craniofacial Unit, this initial assessment includes review by a Craniofacial surgeon, Neurosurgeon, Ophthalmologist as well as detailed 3D CT scan examination.

Metopic synostosis treatment

Where the triangular deformity is sufficiently severe, surgical correction by a Fronto-orbital advancement (FOA) is performed between 6-12 months of age. Any further surgery after infancy in this condition is uncommon. Further details of the surgery and aftercare are available on the Australian Craniofacial Unit (ACFU) website.

Long term follow-up until skeletal maturity is routine to monitor neuro-development and forehead shape and form.
