Virtual Surgical Planning for Mandibular Distraction in Infants with Robin Sequence

Area of Science:

• Craniofacial Surgery
• Pediatric Surgery
• 3D Printing in Medicine

Background:

• Mandibular distraction osteogenesis (MDO) is effective for obstructive sleep apnea (OSA) in Robin sequence (RS).
• Current MDO techniques carry risks to adjacent structures like the inferior alveolar nerve and developing teeth.
• Preoperative planning can optimize surgical outcomes and safety.

Purpose of the Study:

• To present an algorithm for virtual surgical planning (VSP) and 3D-printed cutting guide fabrication for MDO in infants with RS.
• To explore how VSP and 3D printing can improve the MDO technique.
• To reduce the risk of damage to critical anatomical structures during MDO.

Main Methods:

• Development of a VSP algorithm tailored for infant MDO.
• Design and 3D printing of patient-specific cutting guides based on VSP.
• Application of the algorithm and guides in the context of MDO for RS.

Main Results:

• The proposed algorithm facilitates precise virtual surgical planning.
• 3D-printed cutting guides enable accurate osteotomy.
• This approach has the potential to minimize operative risks and improve MDO efficacy.

Conclusions:

• Virtual surgical planning combined with 3D-printed guides offers a promising advancement for MDO in infants with Robin sequence.
• This integrated approach enhances surgical precision and patient safety.
• Further studies are warranted to validate long-term outcomes.
