[2025-10-02T07:44:53.547125] [PI reasoning] **Clarifying cranial suture fusion**

I need to clarify the effects of early fusion of cranial sutures, specifically concerning brachycephaly. When the coronal suture fuses prematurely, it results in a short, broad head shape, known as brachycephaly. In contrast, fusion of the sagittal suture leads to scaphocephaly, characterized by a long and narrow head. Several other conditions like turricephaly and trigonocephaly arise from different sutural fusions. I should determine the answer as A and look for supporting literature for evidence.
