Control study on submental island flap and free skin graft in buccal reconstruction of buccal defects after resection of buccal cancers by in aged patients / 重庆医学

ABSTRACT

Objective To observe and evaluate the clinical effect of submental island myocutaneous flap(SIMF) and free skin graft(FSG) for the reconstruction of buccal defect resulted from the buccal carcinomas .Methods Forty-four aged aging patients di-agnosed with the buccal carcinomas were operated by the total dissection of primary tumor and selective neck dissection and recon-structed simultaneously with SIMF(19 cases) and FSG(25 cases) .The degree of postoperative cheek shape ,limitation of mouth o-pening ,speech sound ,and function of chewing were observed and analyzed .Results Eighteen SIMFs were completely survived .The residual muscle flap had a good blood supply after the debridement of skin island in one case ,the successful rate of flaps was 94 .7%(18/19) while 100% (25/25) .The donor site of SIMF was sutured directly .Follow-up was taken in 12 months for all patients .In SIMF group ,the degree of postoperative cheek shape ,limitation of mouth opening ,speech sound ,and function of chewing were bet-ter than those of FSG group in FSG group(P0 .05) .Conclusion The submental island flap is an excellent choice for the reconstruction of cheek defects in aging patients af-ter resection of buccal carcinoma .With acceptable cosmetic ,functional results and reasonable oncological saftety ,SIMF has a prom-ising prospect in head and neck surgery .
