Summary
Surgery-first, two-jaw orthognathic surgery with rib bone grafting effectively treated severe micrognathia and obstructive sleep apnea in an adult with Pierre Robin sequence (PRS) after prior distractions.
Area of Science:
- Craniofacial Surgery
- Orthognathic Surgery
- Pediatric Surgery
Background:
- Pierre Robin sequence (PRS) presents micrognathia, glossoptosis, and airway obstruction, often necessitating early intervention.
- While mandibular distraction osteogenesis is common in infancy, adults may experience residual issues like micrognathia, occlusal problems, and aesthetic concerns.
- Revisiting previously distracted mandibles poses challenges due to scarring, bone quality, and altered anatomy.
