A septal extension graft (SEG) can control nasal tip projection, shape, and rotation. SEG and dorsal alloplastic implants have predominated in Asian rhinoplasty, leading to iatrogenic complications such as a foreshortened nose and destruction of remaining septum. The lower nasal two-thirds can be enhanced anteriorly and caudally using the septal L-strut extension graft in Asians with relatively small noses. The septal L-strut extension graft is indicated in primary cases in which the bony dorsum is acceptable but the cartilaginous dorsum is relatively hypoplastic, and in secondary cases with an iatrogenic short-nose deformity due to alloplastic implants.
鼻中隔延伸移植片（SEG）可控制鼻尖突出度、形状和旋转。在亚洲人鼻整形术中，SEG和鼻背异体植入物占主导地位，导致了诸如鼻缩短和剩余鼻中隔破坏等医源性并发症。对于鼻子相对较小的亚洲人，可使用鼻中隔L形支撑延伸移植片从前后方向增强鼻下部三分之二。鼻中隔L形支撑延伸移植片适用于以下情况：在原发性病例中，骨性鼻背可接受，但软骨性鼻背相对发育不全；在继发性病例中，因异体植入物导致医源性短鼻畸形。
