延长下斜方肌肌皮瓣修复颅底缺损

目的观察延长下斜方肌肌皮瓣修复颅底缺损的效果。方法 11例颅底肿瘤切除后的缺损患者,其中男性9例,女性2例。恶性肿瘤9例,良性肿瘤2例,修复均与手术同期完成。结果 7例患者Ⅰ期愈合,3例皮瓣远端部分坏死,1例切口裂开。恶性肿瘤患者的1年生存率为100%,2年生存率为67%。以上术式功能修复效果好,修复局部有不同程度的塌陷畸形,外形效果一般。结论延长下斜方肌肌皮瓣术式可用于颅底肿瘤切除后缺损的Ⅰ期修复,功能效果好,外形效果一般。

Reconstruction of the skull base defect with lower trapezius musculocutaneous flap

Objective To observe the clinical outcomes of the reconstruction of the skull base defect with the lower trapezius musculocutaneous flap. Methods Eleven patients with skull base tumors, including 9 males and 2 females, were enrolled into this study. Among them, nine patients had malignant tumors and 2 had benign ones. The reconstructions were performed in the same stage while the tumors were resected. Results The first-stage healing was found in 7 patients. Second-stage healing occurred in 4 patients, among whom 3 patients had skin necrosis in distant part of the flaps and 1 wound dehiscence. All patients had satisfied functional results. The 1-year survival rate was 100% and 2-year survival rate was 67%. Conclusion The lower trapezius musculocutaneous flap is a useful local pedal flap in skull base reconstruction. The functional results were satisfying.
