Abstract：
BACKGROUND: The septal L-strut extension graft (SLEG) consists of anterior extended spreader graft and caudal septal extension graft. SLEG is used to increase the anterocaudal projection from a low-profile nose by creating the de-novo septum. This retrospective study verified the effectiveness of SLEG in improving the nasal function in East Asians.
METHODS: Medical records of patients who underwent septorhinoplasty with SLEG were retrospectively reviewed. The clinical features showed under-projected lower two-thirds of the nose with septal deviation, saddle nose, and short nose. We analyzed the post-operative changes in the NOSE score and variables of nasal geometry measured using acoustic rhinometry through long-term follow-up.
RESULTS: Patients were divided into two groups, those who underwent SLEG with turbinoplasty (Group A) and SLEG alone (group B). The NOSE scores decreased significantly in groups A and B, and the improvement was statistically more significant in Group A (p < 0.05). Acoustic rhinometry showed an increase in nasal cavity volume (VOL1) on the deviated side in Group A, and an increase in minimal cross-sectional area 1 (MCA1) on the deviated side in Group B (p < 0.05). The non-deviated side did not show significant reduction in MCA1 and VOL1 after SLEG with or without turbinoplasty. Thus, SLEG, by itself, improved airway function in East Asians.
CONCLUSIONS: SLEG has proven to be valuable in improving nasal function.

摘要：
背景：中隔L型撑杆延长移植物（SLEG）由前部延长撑杆移植物和尾部中隔延长移植物组成。SLEG用于通过创建从头隔膜来增加低轮廓鼻子的前尾投影。这项回顾性研究证实了SLEG在改善东亚人鼻功能方面的有效性。
方法：回顾性分析SLEG鼻中隔成形术患者的病历。临床特征显示鼻中三分之二的鼻部投射不足，马鞍鼻子，鼻子短。通过长期随访，我们分析了使用声学鼻法测量的鼻孔评分和鼻孔几何形状变量的术后变化。
结果：患者分为两组，行SLEG伴鼻甲成形术(A组)和单行SLEG(B组)的患者.A组和B组的NOSE评分明显下降,A组改善有统计学意义(p<0.05)。声学鼻测显示A组偏侧鼻腔容积(VOL1)增加,B组偏离侧的最小横截面积1(MCA1)增加(p<0.05)。有或没有鼻甲成形术的SLEG后，未偏离侧的MCA1和VOL1均未显示出显着降低。因此，SLEG,本身,改善东亚人的气道功能。
结论：SLEG已被证明在改善鼻功能方面具有重要价值。
