Objective To evaluate the effect of sternocleidomastoid island myocutaneous flap applicating in reconstructing defect of head and neck neoplasms after operation. Methods We used sternocleidomastoid island myocutaneous flap to restore defect postoperation of head and neck neoplasms for 9 patients. Five patients used flap to reconstruct defect of oral mucosal, one case pucker myocutaneous flap, part of it restore oral mucosal defect, part restore skin defect of cheek, the others reconstruct defect of cheek or parotid gland. Seven cases used polyhole titanium to reconstruct mandible bone at the same time. Results Eight cases used sternocleidomastoid island myocutaneous flap survival postoperation.one case’s flap appeared necrosis of distant part and recover after one and a half month. Conclusion Pedical sternocleidomastoid island myocutaneous flap can provide huge flap supply, survival rate higher, easy to execute and not complex, it is suitable for clinical doctors to reconstruct defect after operation fo Objective To evaluate the effect of sternocleidomastoid island myocutaneous flap applicating in reconstructing defect of head and neck neoplasms after operation.
