Mandibular odontogenic myxoma: from the resection to the rehabilitation—case report

Odontogenic myxoma is a rare tumor that arises from remains of the mesenchymal cells of a tooth germ, it’s a benign lesion however locally aggressive, it occurs most often in young adults, specially at the second and third decade of life with no gender predilection, the mandible is the most affected site, nevertheless involvement of the maxilla has been reported. Clinically this pathology when smaller in size may not show any clinical alteration except at radiological exam, as it evolves it promotes painless expansion of the cortical bone, and can displace teeth, radiographically the myxoma shows a unilocular or multilocular radiolucency, the margins are irregular and the defect may contain thin residual bone arranged at a right angles to one another, described as a “stepladder pattern”, large myxoma of the mandible may show a “soap bubble” radiolucent pattern. The treatment of choice to minimize recurrence, is the extensive resection due to the ability of the lesion to infiltrate the surrounding bone. The rehabilitation of those patients promotes a great challenge for the surgeon, use of microvascular reconstruction techniques, osseous free flaps and other procedures such as distraction osteogenesis have become techniques of great value in the reconstruction of segmental mandibular defects, when associated with osseointegrated implants and prosthetics allows the recovery of both function and aesthetics of the individuals. This paper has the aim of presenting a case report of full treatment for myxoma at the mandibular symphisis from the surgical resection, bone graft reconstruction, till oral rehabilitation.
