感染条件下大块下颌骨缺损一期修复的研究

A STUDY OF ONE STAGE RECONSTRUCTION OF MASSIVE DEFECT OF MANDIBLE UNDER CONDITION OF INFECTION

报道了在解剖学研究的基础上,采用吻合髂腰血管髂支(或第四腰动脉前支)和旋髂深血管的超长度的髂骨瓣移植,在受区有感染的条件下,一期修复大块下颌骨缺损6例获得成功。其特点是移植髂骨瓣的血供丰富,抗感染力更强,生长愈合更快,可塑性大,适应证宽,术后下颌骨的外形与功能恢复良好。

Bassed on an anatomical study,the transplantation of iliac flap with the employment of iliac branch of ilio-1 tmbar artery (or the anterior branch of the fourth lumbar artery) and an extralength of the deep circumiliac artery in the reconstruction of massive mandibular defects is reported in this article.There was infection in the recipient area.The operation was done in 6 cases with successful result. The flap is characterized by:richer blood supply of replanted iliac flap,stronger anti-infection property,better healing,better remodelling and wider indications.Therefore,recovery of the contour of mandible and its function are good after operation.
