Vital Staining Role in Resection and Reconstruction of Tongue Cancers with Free Flap - A Comparative Study.

Introduction: The purpose of this study is to compare and infer the most suitable dye for visualisation of ipsilateral and contralateral sentinel lymph nodes (SLNs), positive, negative outcomes, sensitivity, their specificities and visualisation of anastomosed blood vessels in microvascular reconstruction of tongue cancers.

Materials And Methods: This is a prospective comparative study involving twenty patients diagnosed with squamous cell carcinoma of the tongue treated with wide excision of primary tongue tumour, modified functional neck dissection and microvascular reconstruction with radial forearm free flap. Consecutive random allocation was done into two groups with ten patients each.
