部分上颌骨切除(heminaxillectomy)后的修复有三个大难题:(1)颧部轮廓和上颌窦壁的恢复;(2)为托牙提供骨骼支持的腭部的修复;(3)上颌窦生理功能的恢复。以往解决这些难题有采用假牙修复和充填体,也有采用局部或远处皮瓣。作者介绍一种部分上颌骨切除后用颊脂垫(bucc-al fat pad)作衬里覆盖自体肋骨或骼骨植骨,以免植骨暴露在上颌窦内。解剖颊脂垫是一个被薄膜覆盖的叶状凸起的脂 Partial repair of the heminaxillectomy has three major challenges: (1) restoration of the zygomatic contour and maxillary sinus wall; (2) repair of the palatal support for the support of the denture; (3) physiological function of the maxillary sinus Recovery. In the past to solve these problems are the use of dentures repair and filling body, but also the use of local or remote flap. The authors describe a partial maxillary resection with a bucc-al fat pad (bucc-al fat pad) to cover the autologous ribs or iliac bone graft in order to avoid bone exposure to the maxillary sinus. Anatomical buccal fat pad is a thin film covered leaf-shaped raised fat
