Tongue cancers are common in the spectrum of oral malignancies. In base of tongue cancers, tumour excision might lead to injury of ipsilateral or both lingual arteries, leading to ischemia of residual, native tongue. Free radial artery forearm flap is commonly used for tongue reconstruction. It can also be used as a flow-through flap for the reconstruction of the tongue defect as well as to revascularise the cancer-free tongue remnant. We report here two cases of base of tongue excision for which free flow-through radial forearm flap was used to reconstruct the tongue defect as well as salvage the remaining part of ischemic tongue. This technique can be effectively considered in selected cases of vascular compromise due to lingual vessel sacrifice to preserve the cancer-free anterior native tongue tissue with improved functional outcomes.
