Apert syndrome


ICD-10: Q87.0B


General information

Estimated occurrence
1:100,000 live births.
Autosomal dominant genetic trait with Aberration on chromosome 10. Most often spontaneous mutation.
General symptoms
Cranial malformations and malformations of the hands and feet. Fusion of the cervical vertebrae is frequent. Children with Apert Syndrome often have delayed speech and language development, as well as learning disabilities. They also generally have vision and hearing problems. Severe acne is common while growing up.
Acrocephalosyndactyly type 1

Orofacial/odontological symptoms

Premature fusion of the bones at the base of the skull (craniosynostosis) gives rise to craniofacial malformations. The palate is often high and narrow, and some children are born with a cleft soft palate. Crowded teeth and an underbite are common. In a recently published study irregularities were noted in the region of the dentino-enamel junction, which could affect caries progression and also make dental management more difficult. Constriction in the upper respiratory system may lead to breathing difficulties and sleep apnea (frequently stopping breathing when asleep). Craniofacial malformations lead to articulation difficulties and impair chewing ability.

Advice on follow-up and treatment

  • In cases of craniofacial malformations, a specialist team will be needed for follow up and treatment.
  • Most individuals with Apert syndrome require both orofacial surgery and extensive orthodontia.
  • Many of these individuals require supplementary prophylactic dental care.
  • Speech and language disabilities are dealt with by a speech therapist.
  • Snoring problems should be followed up by a physician.
