Is Monitoring of Free Flaps in the Oral Cavity Feasible with Hyperspectral Imaging?

Hyperspectral imaging (HSI) provides spectral information about hemoglobin, water, and oxygen supply and thus has great potential in perfusion monitoring. This study explored HSI's feasibility in postoperative monitoring of intraoral free flaps in 14 patients undergoing reconstructive head and neck surgery with radial forearm free flaps.
