PURPOSE
To determine whether identification and incorporation of the pyriform ligament in the alar cinch results in decreased alar base widening compared with standard alar cinch techniques.
MATERIALS AND METHODS
This was a retrospective case series and the sample was composed of patients undergoing Le Fort I osteotomy. Intraoperatively, the pyriform ligament was identified and incorporated in the alar cinch suture. Greatest alar width (GAW) measured immediately after closure was compared with GAW measured at least 5 months postoperatively. The change in alar base width was compared with that reported in the literature using other alar cinch techniques. Two case examples are reported.
RESULTS
The sample was composed of 15 patients (mean age, 27.1 yr; 27% female). The mean postoperative change in GAW was 1.0 ± 0.6 mm (2.59 ± 1.59%). Postoperative change in alar base width reported in the literature ranged from 0.5 to 10.8%.
CONCLUSION
The pyriform ligament is easily identified during exposure of the maxilla and pyriform aperture and can be used to control widening of the alar base after Le Fort I osteotomy.
目的
确定与标准鼻翼收紧技术相比，在鼻翼收紧术中识别并纳入梨状韧带是否能减少鼻翼基底增宽。
材料与方法
这是一项回顾性病例系列研究，样本由接受勒福Ⅰ型截骨术的患者组成。术中，识别梨状韧带并将其纳入鼻翼收紧缝合。将关闭后立即测量的最大鼻翼宽度（GAW）与术后至少5个月测量的GAW进行比较。将鼻翼基底宽度的变化与文献中使用其他鼻翼收紧技术报道的变化进行比较。报告了两个病例实例。
结果
样本由15例患者组成（平均年龄27.1岁；27%为女性）。GAW的平均术后变化为1.0±0.6mm（2.59±1.59%）。文献报道的鼻翼基底宽度术后变化范围为0.5%至10.8%。
结论
在暴露上颌骨和梨状孔时很容易识别梨状韧带，并且可用于控制勒福Ⅰ型截骨术后鼻翼基底的增宽。
