Preliminary study on superior trapezius myocutaneous flap through accessory nerve anastomosis in reconstructing the tongue defect after the operation of tongue squamous cell carcinoma / 重庆医学

ABSTRACT

Objective To explore the clinical effects of superior trapezius myocutaneous flap through accessory nerve anastomosis in immediately repairing the tongue defect after tongue squamous cell carcinoma operation.Methods Six cases of tongue squamous cell carcinoma diagnosed by pathology in the Maxillofacial Surgery Department of the Affiliated Stomatological Hospital of Chongqing Medical University from January 2015 to December 2016 were collected and Performed the tongue-neck combined radical operation.The superior trapezius myocutaneous flap simultaneous repair of tongue defect with accessory nerve and hypoglossal anastomosis was adopted during operation.The wound surface of donor site was directly sutured without skin grafting.Results All flaps survived.After 6 months to one year,the flap became mucolized,the surface of flap was similar to the normal oral mucosa with good character.The movement of reconstructed tongue mainly depended on the movement of residual tongue at early stage (within postoperative 3 months).After 6 monthsthe reconstructed tongue had obvious mobility,but the flexibility was poorer than that of the uninjured side,and the patient was satisfied with the language and swallowing function.Conclusion The superior trapezius myocutaneous flap through the accessory nerve anastomosis is one of the ideal skin flaps for repairing tongue defect after e tongue squamous cell carcinoma operation.
