title: Novel technique for harvesting the sternoclavicular graft.
abstract: OBJECTIVE
  Originally introduced for mandibular reconstruction more than 40 years ago, the sternoclavicular graft (SCG) has gained widespread popularity for the reconstruction of the ramus-condyle unit (RCU) owing to its anatomic and histological likeness to the normal mandibular condyle. Conventional longitudinal osteotomy design for its harvest has been fraught with considerable complications at the donor site including fracture clavicle and major neurovascular injury. In an attempt to alleviate these ill effects, a new technique for procuring the sternoclavicular graft is presented.
  
  
  METHODS
  A split-thickness cortico-cancellous graft was harvested form the sternal end of the clavicle along with the articular disk with the osteotomy cut oriented parallel to the coronal plane, with limited soft tissue dissection. Donor site complications were assessed in terms of incidence of clavicle fracture, neurovascular injury, pleural tear and radiographic healing as seen in the six-month postoperative chest radiograph.
  
  
  RESULTS
  17 patients suffering from unilateral temporomandibular joint ankylosis underwent SCG harvesting for RCU reconstruction following osteoarthrectomy. No adverse events were seen in the intra- and post-operative period in any patient and satisfactory radiographic osseous healing was observed after six months.
  
  
  CONCLUSIONS
  The proposed harvest technique for SCG results in reduced donor site morbidity and favourable healing and greater patient comfort.
