Types of craniosynostosis
Nonsyndromic Craniosynostosis
Single suture craniosynostosis
- MC suture: sagittal > unilateral coronal > bilateral coronal > metopic > lambdoid
Pathology
- Bone growth primarily perpendicular to & occurring at suture lines; premature fusion → abnormal growth
Syndromic craniosynostosis
Selected craniofacial dysmorphic syndromes
| Syndrome | Sporadic | Inherited | Craniofacial findings | Associated findings |
|---|---|---|---|---|
| Crouzon Syndrome (craniofacial dysostosis) | Yes (25%) | FGFR2 (AD) | Craniosynostosis of coronal & basal skull sutures, maxillary hypoplasia, shallow orbits, proptosis | HCP rare |
| Apert Syndrome (acrocephalosyndactyly) (MC) | Yes (95%) | FGFR2 (AD) | same as Crouzon | Syndactyly of digits 2, 3, 4; shortened UE, HCP common |
| Kleeblattschädel Syndrome | Yes | AD | Craniosynostosis /w trilobular skull | isolated, or with Apert's or thanatophoric dwarfism |
