Mandibular reconstruction in an irradiated field using median sternotomy and anterior rib axial graft.

Mandibular reconstruction in an irradiated field continues to be a challenge to the reconstructing surgeon. Several methods use rib grafts to bring vascularized tissue to the mandibular region. A median sternotomy provides excellent exposure to harvest the internal mammary artery and anterior axial rib graft for subsequent mandibular reconstruction. The modified technique described provides an alternative method of bringing a vascularized rib graft to an irradiated field for mandibular reconstruction avoiding multiple rib resections and microvascular anastomosis. This technique has been used in two patients who had anterior mandibular resection and irradiation therapy for advanced squamous cell carcinoma. The results from this technique were excellent and without major complications.
