胸锁乳突肌瓣在腮腺良性肿瘤切除术中的应用

Applicatian of Sternocleidomastoid Muscle Flap in Benign Parotidectomies

目的探讨腮腺良性肿瘤切除术中应用胸锁乳突肌瓣充填术区缺损并预防Frey综合征的效果。方法腮腺良性肿瘤患者120例,随机分为试验组60例、对照组60例。试验组在切除腮腺肿瘤后,转移带蒂胸锁乳突肌瓣充填术区凹陷;对照组在切除腮腺肿瘤后,直接关闭创口。2组随访1.5～5.0年。结果2组患者伤口均Ⅰ期愈合。对照组创区术后凹陷发生率为100%(60/60),Frey综合征发生率为83.33%(50/60);试验组创区术后凹陷发生率为3.33%(2/60),Frey综合征发生率为11.76%(7/60)。2组间创区术后凹陷差异有统计学意义(χ2=10.362,P=0.0014),2组间Frey综合征发生率差异有统计学意义(χ2=18.154,P=0.0078)。结论胸锁乳突肌瓣可改善腮腺良性肿瘤切除术后的局部凹陷并降低Frey综合征发生率。

Objective To access the effect of sternoeleidomastoid muscle flap in the restoration of sunken deformity of face and preventing Frey＇s syndrome after parotidectomy. Methods Paticnts with benign parotid tumors （ 120 cases） were selected and randomly divided into experimental group （60 cases） and control group （60 cases）. The control group were treated with traditional parotidectomy, while patients in experimental group were treated with modified parotidectomy including repairng the soft tissue defects by sternocleidomastoid muscle flap. Results Sunken deformities were significant in control group （ 100% ）, incidence rate of Frey＇ s syndrome was 83.33% （50/60）. While there were no obvious sunken deformities in experimental group （96.67%） , incidence rate of Frey＇ s symlrome was 11.67% （7/60） , and siginificently lower than that of eontrol group （P 〈0.01 ）. Conclusion Sternocleidomastoid muscle flap is effective to correct the deformity of the face ＇after parotidectomy and decrease the occurrence of Frey＇ s syndrome.
