Name of the Condition

• Craniofacial Dysostosis
• Also known as Crouzon Syndrome or Craniofacial Dysplasia.

Summary

Craniofacial dysostosis is a congenital condition characterized by the premature fusion of certain skull bones, affecting the shape of the head and face. This typically leads to facial anomalies and may result in other complications depending on the severity of the condition.

Causes

• The condition is primarily caused by genetic mutations, commonly in the FGFR2 gene.
• It is inherited in an autosomal dominant pattern, meaning only one parent needs to carry the potential for the mutation to pass it on to their child.

Risk Factors

• Family history of craniofacial dysostosis or related genetic conditions increases the risk.
• Genetic mutations associated with the condition can occur spontaneously.

Symptoms

• Distinctive facial features such as wide-set, bulging eyes, and a beaked nose.
• Dental problems due to misalignment of the jaws.
• Potential impaired vision or hearing due to cranial pressure.
• Breathing difficulties or obstructed airways.

Diagnosis

• Physical examination of facial and cranial features by a healthcare professional.
• Genetic testing to identify mutations in the FGFR2 gene.
• Imaging tests like CT or MRI scans to view skull and facial structures.

Treatment Options

• Surgical intervention is common to correct skull and facial anomalies and relieve cranial pressure.
• Orthodontic treatments to address dental issues.
• Supportive therapies, such as speech or hearing therapy, to manage associated symptoms.

Prognosis and Follow-Up

• With timely surgical and therapeutic interventions, individuals can have a favorable outlook.
• Regular follow-ups are essential to monitor cranial development and manage complications during growth.

Complications

• Without treatment, patients may face increased cranial pressure, leading to neurological damage.
• Possible developmental delays due to sensory impairments.

Lifestyle & Prevention

• No definitive preventive measures as it is a genetic condition.
• Prenatal genetic counseling may be beneficial for at-risk families.

When to Seek Professional Help

• Seek immediate medical attention if a child exhibits unusual facial features or breathing difficulties.
• Regular medical consultations are crucial to monitor development and address arising complications.

Tips for Medical Coders

• Ensure precise coding by verifying both the genetic mutations and the clinical presentation.
• Avoid confusing with other craniosynostosis conditions; Q75.1 specifically refers to craniofacial dysostosis.
