Mandibular Distraction in Dual Syndromic Diagnosis

Area of Science:

• Craniofacial surgery
• Genetics
• Pediatric surgery

Background:

• Mandibular distraction surgery outcomes vary in Treacher-Collins syndrome.
• Dual syndromic diagnoses present unique management challenges.
• Severe retrognathia in Treacher-Collins syndrome may necessitate tracheostomy.

Purpose of the Study:

• To present a case of Treacher-Collins syndrome with a concurrent Angelman syndrome diagnosis.
• To discuss challenges in mandibular distraction for patients with dual diagnoses.
• To explore surgical options for failed decannulation after multiple mandibular distraction attempts.

Main Methods:

• Case report of a patient with Treacher-Collins and Angelman syndromes.
• Review of genetic workup and surgical history.
• Discussion of craniofacial manipulation difficulties in dual diagnoses.

Main Results:

• The patient with Treacher-Collins syndrome and Angelman syndrome experienced failed repeat mandibular distraction and decannulation.
• Genetic testing confirmed Angelman syndrome, indicating severe developmental delay.
• Dual diagnoses complicated craniofacial surgical management.

Conclusions:

• Patients with dual diagnoses, such as Treacher-Collins and Angelman syndromes, may have compromised bone formation and mineralization.
• This underlying issue can significantly challenge craniofacial surgical interventions.
• Alternative surgical strategies are crucial for managing complex cases with failed mandibular distraction.
