Case in brief
A 4-year-old boy with recurrent trabecular juvenile ossifying fibroma underwent wide segmental mandibulotomy with preservation of the periosteum, leaving a 6-cm parasymphyseal mandibular defect. Reconstruction used a cadaveric tibial allograft combined with a cellular bone allograft. Imaging showed progressive remodeling and complete osseous continuity of the mandibular arch at 22 months. Clinical follow-up to 42 months documented excellent function and facial harmony.
What made this case unusual
The report describes pediatric reconstruction of a large mandibular defect using a cadaveric tibial allograft combined with a cellular bone allograft, with complete arch continuity on imaging.
Diagnostic / clinical pearl
In this child, imaging documented progressive remodeling to complete mandibular arch continuity after reconstruction with combined tibial and cellular bone allografts; clinical follow-up also noted excellent function and facial harmony.
Why it matters
The report adds a clinical example to the limited literature on pediatric mandibular reconstruction using cellular bone allografts and suggests potential for durable, growth-compatible reconstruction.
