About this trial
The gold standard for reconstruction of the jaw is the utilization of a bone free tissue transfer. Scapula reconstruction is an excellent option for elderly patients, those with significant comorbidities and for complex defects with large soft tissue reconstructive requirements. The scapula is supplied by the angular artery and circumflex scapula arteries. No studies have shown with objective measures, the viability of the lateral border of the scapula bone supplied by either the angular artery or circumflex scapula arteries. The aim of this observational study is to demonstrate with objective clinical measures, via SPY-Q software analysis, that the angular artery can adequately supply the scapula tip flap including with a single osteotomy giving two bone segments, in 30 patients who will undergo reconstructive head and neck surgery at LHSC.
