Summary
Mandibular distraction osteogenesis (MDO) effectively treats obstructive sleep apnea (OSA) in infants with Pierre Robin sequence (RS). Virtual surgical planning (VSP) enhances MDO precision and patient outcomes.
Area of Science:
- Craniofacial Surgery
- Pediatric Surgery
- Sleep Medicine
Background:
- Obstructive sleep apnea (OSA) in infants with Pierre Robin sequence (RS) often requires surgical intervention.
- Mandibular distraction osteogenesis (MDO) is a primary surgical option for refractory OSA in RS.
- Virtual surgical planning (VSP) may enhance MDO accuracy and safety.
Purpose of the Study:
- To evaluate the efficacy and safety of MDO for OSA in RS infants using VSP.
- To assess the precision of osteotomies created with 3D-printed cutting guides.
- To report airway outcomes and complication rates.
Main Methods:
- Retrospective study of 17 RS infants undergoing MDO with VSP and 3D-printed guides.
- Preoperative maxillofacial CT scans for VSP and guide fabrication.
- Analysis of osteotomy designs, surgical execution, bone formation, airway outcomes, and complications.
Main Results:
- All MDO procedures were performed as planned using VSP and cutting guides.
- Successful airway outcomes were achieved in all patients.
- Bone formation was evident in all cases; four minor complications occurred, with no major complications.
Conclusions:
- MDO is a successful and safe procedure for managing OSA in infants with RS.
- VSP significantly aids in the precise design and execution of MDO.
- This approach offers favorable outcomes for pediatric obstructive sleep apnea management.
