Summary

Wound complications, such as salivary-cutaneous fistulas and skin necrosis, result in significant patient morbidity and death. Head and neck wounds are complicated because of multiple tissue layers, critical structures and variable vascularity. When vascularity is compromised, wounds do not heal and can lead to life threatening haemorrhage or morbid infections. The field of microsurgical reconstruction has developed and expanded over the last 20 years to specifically ameliorate these issues. The challenge is that the vascularity of the microsurgical transplant or the recipient tissue bed can have areas of decreased vascularity that cannot be appreciated by the surgeon's intraoperative exam alone. Surgeons would be able to make better decisions with respect to the vascularity if there was an imaging technique that could indicate the vascular supply of the tissues undergoing surgical reconstruction.

Laser-assisted indocyanine green fluorescent dye angiography (LA-ICG) using the SPY System (Novadaq Technologies Inc., Richmond, British Columbia, Canada) is an intraoperative vascular imaging technique that improves the ability of a surgeon to assess the vascular supply in the surgical bed. This tool, which is approved by Health Canada for reconstructive surgery, has been used extensively in breast reconstruction and gastrointestinal procedures with encouraging results. The ability to address ischemic tissues intraoperatively could potentially decrease the rate of devastating wound complications in head and neck surgery patients. The objective of this observational study is to assess the effectiveness of LA-ICG in head and neck reconstructive procedures to reduce the rate of skin necrosis and fistula.
