Since the introduction of free flap as a method of tissue defect reconstruction, flap viability has improved dramatically due to advanced microsurgical techniques. Despite the high success rates, partial circulatory failure, resulting in necrosis remains a relatively common complication. Therefore, an objective monitoring technique is preferred to complement the current rather subjective and limited gold standard for assessing flap viability. To evaluate objective, optical, non-invasive techniques for early detection of tissue hypoxia, this thesis focused on two (near-infrared spectroscopy and hyperspectral imaging) techniques. Both techniques have proven to be reliable, accurate, and user-friendly. However, neither technique can (yet) fully replace the gold standard of clinical flap assessment.
