自体脂肪颗粒移植治疗声带沟

Transplantation with autologous fat granules to cure vocal cord sulcus

目的探讨自体脂肪颗粒移植治疗声带沟的疗效。方法对32例声带沟患者采用改良的自体脂肪颗粒移植技术进行治疗。自体脂肪颗粒注射移植1—2次，中间间隔3—6个月。通过术前、术后声门裂隙及患侧声带表面积，以及患者自我感觉等随访，评价其治疗效果。结果最长4．5年，平均2．5年的随访发现在1～2次自体脂肪注射后，脂肪可以在受区长期存活。78．13％以上的患者对疗效满意，小于9．38％的患者对疗效不满意。结论自体脂肪移植技术用于声带沟是一项安全而有效的治疗方法。

Objective To discuss the effects of transplantation with autologous fat granules to cure vocal cord sulcus. Methods In this study we treated 32 cases of vocal cord sulcus with improved autologous fat grafting technique. Each case was treated 1 - 2 times and the interval period was 3 - 6 months. The result was based on comparing the size of fissure glottis, the surface area of the sick vocal cord and patients self evaluation. Results Long time follow up showed that fat graft can be alive in the recipient site for long time after 1 -2 times autologous fat injection. More than 78.13% patients were satisfactory with the curative effect while less than 9.38% patients were unsatisfactory. Conclusions Autologous fat grafting technique is an effective and safe treatment for vocal cord sulcus.
