Contouring split ribs for correction of severe mandibular atrophy

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Atrophic mandible presents challenges in reconstruction.
• Current grafting techniques can be complex and yield suboptimal aesthetic and functional results.
• Rib grafts are a viable option for mandibular augmentation.

Purpose of the Study:

• To describe a novel method for contouring split rib grafts for mandibular augmentation.
• To evaluate the efficacy of this technique in achieving excellent symmetry, arch, and alveolar ridge form.
• To compare the ease of placement with traditional single rib grafting methods.

Main Methods:

• A technique for splitting and contouring rib segments was developed.
• These split rib grafts were utilized for augmentation of the atrophic mandible.
• Placement ease and final graft form were assessed qualitatively.

Main Results:

• The described method allows for excellent symmetry, arch form, and alveolar ridge contouring.
• Placement of the split rib graft onto the mandibular ridge was found to be easier than using a single rib with vertical saw cuts.
• The split rib technique facilitates passive placement, simplifying the surgical procedure.

Conclusions:

• Contouring split ribs offers a simplified and effective approach for mandibular augmentation.
• This technique improves aesthetic and functional outcomes by enhancing graft adaptability and placement.
• The method represents an advancement in reconstructive surgery for the atrophic mandible.
