Question

Name four syndromes that occur as a result of premature closure of the cranial sutures?

Answer 1

Craniosynostosis involves the premature closure of cranial sutures, causing syndromes like scaphocephaly, Crouzon Syndrome, Apert Syndrome, and Pfeiffer Syndrome. These can lead to skull deformities and affect brain development, often treated with surgery.

Step-by-step explanation:

Four syndromes that result from the premature closure of the cranial sutures, a condition known as craniosynostosis, include:

1. Scaphocephaly: Resulting from the closure of the sagittal suture, leading to a long, narrow head shape.
2. Crouzon Syndrome: Characterized by the early fusion of the skull sutures, leading to various cranial deformities and potentially impeding brain development.
3. Apert Syndrome: Involving early closure of the coronal sutures, causing distortions of the head and face.
4. Pfeiffer Syndrome: Premature closure of multiple cranial sutures, which affects skull and limb development.

Craniosynostosis can alter or impede proper brain growth and development due to severe constraints on skull growth. Treatment often involves surgery to allow the skull bones to resume growth.
