[Therapeutic effect of submental flap in repairing of approaching circumferential defects after hypopharyngeal cancer ablation with laryngeal function unpreserved].

OBJECTIVE

To study the effectiveness of repairing nearly circumferential defect with the submental flaps after resection of laryngeal function unpreserved hypopharyngeal cancer.

METHOD: All the cases were treated with the submental flaps after resection of hypopharyngeal cancer with laryngeal function unpreserved.

RESULT: All 13 flaps were alive. Hypopharyngeal fistula occurred in 2 cases. All patients had normal swallowing function. The patients were followed up 6-42 months. Of 13 cases,3 had recurrence at neck Lymph node, but no local hypopharyngeal recurrence was found. Seven cases were followed up more than 3 years, and only 3 of them survived.

CONCLUSION

Submental flap is an ideal tissue flap submental flap in repairing of approaching circumferential defects after hypopharyngeal cancer ablation with laryngeal function unpreserved for the repairment of after approaching circumferential defects after hypopharyngeal cancer ablation with laryngeal function unpreserved, For it is close to the defect region, safe, easy-to-obtain and easy-to-survive.
