Background
Although the uncommon dentinogenic ghost cell tumour (DGCT) is a benign entity, it possesses the ability to cause widespread destruction of the jaws and to recur after bone-preserving therapy. Hence, clear margins should be achieved upon surgery, and reconstruction techniques must often be used to restore osseous defects. However, this can be challenging in cases with involvement of the temporomandibular joint (TMJ), and especially in children.
Case report
We present a case of a DGCT in a 12-year-old boy with wide infiltration of the mandible and the TMJ. A two-staged reconstructive approach was performed. Upon primary surgery, tumour-free margins were obtained and mandibular anatomy was restored using an iliac crest graft and an alloplastic condyle implant for temporary TMJ reconstruction. In a second step 5 months later, having received a customized TMJ prosthesis consisting of a fossa and a condyle component, the TMJ was completely replaced for definitive reconstruction.
Conclusion
A customized TMJ prosthesis could be a solution for reconstruction of the TMJ in children. However, the further course with respect to growth disturbances must be evaluated upon short-term follow-ups and might require additional corrective interventions.
