Abstract

Objective To discuss the clinical outcome of submental island flap used in reconstruction of nearly half tongue defect after resection of tongue cancer. Methods From June 2015 to November 2017, 16 submental island flaps were used to reconstruct nearly half tongue defect after resection of tongue cancer. Tissue flap with submental artery as vessel pedicle and suitable for the defect with anterior belly of digastric muscle was prepared in submental area and transferred to the defect area through the mandibular hyoid muscle tunnel to repair the defect. Results All submental flap transfers were successful.The areas of flaps were 3.0 cm×4.0 cm-4.5 cm×7.5 cm. No local recurrence of tongue SCC was found and no death was noted during 3-24 months of follow-up.The functional and esthetic result such as feeding, speeching, head raiseing were satisfied for patients. Conclusions Higher success rate and scars decrease make submental island flap an reliable choice for reconstruction of nearly half tongue defect after resection of tongue cancer.
