Split-rib graft for reconstruction of the mandible.

Defects in the mandible after tumor surgery were reconstructed with split-rib grafts in 23 patients. Twenty of the patients were preoperatively irradiated with fractioned radiotherapy, ranging from 40 to 85 gray. Partial sequestration appeared in five patients. The ingrowth of the transplant was examined with technetium scintigraphy. Satisfactory cosmetic and functional results were achieved in the great majority of the patients. Split-rib grafting is recommended for reconstruction of the mandible as a safe procedure with little increased operation time and morbidity for the patient and good functional and cosmetic results.
