Free fibular flap reconstruction in mandibular osteopetrosis.

Extensive involvement of the mandible with sclerosis secondary to the rare genetic disorder, osteopetrosis, is a difficult reconstructive problem. It is typically refractory to conservative management or local surgical methods because of vascular compromise of the bone. For this reason, total resection of all involved bone with microvascular graft reconstruction is an ideal method for mandibular reconstruction in osteopetrosis that has not been previously reported.
