Aggressive Osteoblastoma of the Mandible - A Journey of 2 Rare Cases

Abstract

Bone tumours are a distinct entity among which osteoblastoma is a rare variant constituting less than 1% of all bone tumours. The bones most commonly involved include the backbone, sacrum, calvaria, long bones and the small bones of the hand and feet. Osteoblastomas have only 15 % occurrence in the head and neck region with a higher incidence in the mandible. Osteoblastomas are known to have a benign or conventional form and the aggressive form which exhibits locally aggressive behaviour and a hig her proneness for recurrence. We have reported the journey of two rare cases of aggressive osteoblastoma in the mandible. The treatment was planned considering the aggressiveness of the lesion and the reconstruction was carried out with free fibula graft to maintain the aesthetics, function, and to achieve a good quality of life for the patients.
