Unusually rapid bone regeneration following mandibular resection

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Bone Biology

Background:

• Heterotopic bone formation is documented but typically in small, localized deposits.
• Extensive bone regeneration over significant distances is exceptionally uncommon in clinical settings.
• Mandibular defects often require complex reconstructive strategies.

Observation:

• Two young patients presented with unusually rapid and extensive bone regeneration.
• The bone regeneration extended over approximately half the mandible.
• This remarkable healing occurred within a six-month period post-surgery.

Findings:

• The cases involved mandibular resection for benign lesions that became infected intraoperatively.
• Preservation of the periosteum was a key surgical factor.
• Patient age, potential genetic predispositions, and the presence of infection were identified as contributing factors.

Implications:

• These findings suggest that specific conditions can promote accelerated and substantial mandibular bone regeneration.
• Understanding these factors could lead to novel therapeutic strategies for bone defects.
• Further research into periosteum's role and host factors in bone healing is warranted.
