title: Aplasia of the vertex without scalp defect.
abstract: We report a case of an extremely rare craniofacial condition, which, to our knowledge, has previously been reported once only. A male infant presented with a giant congenital bone defect of the skull, in the vertex region (10 x 20 cm) and without scalp deficiency. Minimal turricephaly and moderate orbital hypertelorism were associated with slight limb abnormalities, but psychometrical assessments appeared normal. Nonsurgical treatment was initially decided upon, but spontaneous reossification was so moderate that skull reconstruction was carried out at 28 months of age because of the risk of trauma. A full-size resin cephalic skeletal reconstruction was obtained according to three-dimensional computed tomography using stereolithographic techniques. A titanium plate was customized on the resin model for ideal adaptation to the convex skull defect (8 x 16 cm). Surgery was simply performed, consisting of a preliminary undermining between the dura mater and the scalp and screwing of the custom titanium plate. The initial follow-up was uneventful.
