A case of chronic disseminated histiocytosis X (Hand-Schuller-Christian Disease) of the mandible is presented. Multi-modal approach to management is discussed.
This case describes surgical correction of unilateral coronoid hyperplasia in a 13-year-old boy due to trauma. Treatment included coronoidectomy by intraoral approach after the diagnosis was confirmed. Computed tomography scan and occipitomental view radiograph were utilized for investigation. The resected coronoid process was sent for histopathological study. The histopathological examination revealed decalcified sections showing osteochondroid hyperplasia at the expanded end. On clinical and radiographic review at 2 years postoperation, the patient was well, completely symptom free and had improved mouth opening. This case report demonstrates the management of sports injury related unilateral coronoid hyperplasia. Emphasis was also placed on postoperational rehabilitation to prevent any relapse.
Osteoradionecrosis (ORN) is a well-recognized, debilitating complication of radiotherapy for patients with head and neck cancer. There is no universally accepted treatment for ORN of the jawbones. We report on a case of refractory mandibular ORN treated by sequestrectomy of mandible and autogenous transplantation of fat graft combined with platelet-rich fibrin (PRF). Improved perfusion was observed using the laser Doppler flowmetry. This case highlights the use of autogenous free fat graft and PRF as an adjunct therapy to sequestrectomy in the management of ORN.
