Mandibular distraction in a tracheostomized patient with Pierre-Robin sequence

Area of Science:

• Craniofacial Surgery
• Pediatric Otolaryngology
• Orthognathic Surgery

Background:

• Pierre Robin sequence (PRS) is a congenital condition characterized by glossoptosis, micrognathia, and cleft palate.
• Airway obstruction is a common and potentially life-threatening complication in PRS patients.
• Mandibular distraction osteogenesis is an established technique for correcting mandibular deficiencies.

Observation:

• A case report details a child with PRS undergoing bilateral mandibular distraction using external, nonresorbable devices.
• Following successful mandibular lengthening, the child underwent laryngotracheoplasty to close a pre-existing tracheostomy.
• The child experienced improved respiratory function and quality of life post-intervention.

Findings:

• External nonresorbable distraction devices effectively corrected mandibular hypoplasia in this PRS case.
• Bioresorbable internal devices present advantages but carry risks such as device failure.
• Distraction osteogenesis is a safe, minimally invasive procedure with low infection risk.

Implications:

• Distraction osteogenesis is a viable and effective alternative to tracheostomy for managing life-threatening airway obstruction in Pierre Robin sequence.
• This approach can significantly improve respiratory patterns and overall quality of life in affected children.
• Further research into optimizing distraction device materials and techniques is warranted.
