ABSTRACT
After hemiglossectomy due to tongue cancer, such factors as mobility, sensation, volume and the shape of the tongue are critical elements for successful rehabilitation. As long as there is a residual segment of mobile tongue with an intact motor nerve supply, the mobility of native tongue can be preserved by using tissue with thin, pliable and sensory potential. The residual tongue motion can be maximized by separating the reconstruction of mobile tongue from the reconstruction of the floor of mouth. Six patients who underwent significant glossectomy for squamous cell cancer were reconstructed with a bilobed design of sensate radial forearm flap. One lobe of the flap is used to restore the shape and volume of the tongue, while the other lobe is used to resurface the floor of the mouth. There were no flap failure and fistula formation. In all patients, the tongue mobility was preserved and the earliest recovery of sensation was noted 5 weeks following the surgery. The articulation was good enough for them to perform daily activities. With the bilobed design, we can maximize the mobility of the residual tongue by preventing tethering of the root of tongue to the inner table of the mandible. In this article e present our successful experiences with this method, especially in view of mobility and sensation.
