Tongue reconstruction with tongue base island advancement flap.

Reconstruction of a medium-sized defect of the tongue remains a challenge if aesthetic impairment is to be avoided. In this study, 19 tongue base island advancement flaps were developed to reconstruct medium-sized defects after the tongue squamous cell carcinoma ablations: 13 cases were T1N0M0, and 6 cases were T2N0∼1M0. The largest size amounts to 5.4 × 4.8 cm (length × width), with a mean of 4.6 × 4.4 cm. The tongue base island advancement flap reduces the volume of the tongue base without causing function impairment of the tongue. All patients recovered with good objective and subjective speech and swallowing and aesthetics. No patient developed local recurrence or lymphatic metastasis. The technique of tongue base advancement flap is ideal for functional and aesthetic repair of medium-sized tongue defects after cancer ablation.
