PRS:创新!又快又好地制备出不到0.1mm的超碎颗粒软骨!

众所周知,在鼻整形中,一般采用直径小于0.2 mm的颗粒软骨来塑造更加平滑的鼻背效果。

众所周知,在鼻整形中,一般采用直径小于0.2 mm的颗粒软骨来塑造更加平滑的鼻背效果。然而,制作较小的颗粒软骨需要很长时间。相比之下,尽管切割软骨的工作做得很好,颗粒软骨移植到鼻背之后,鼻背线条可能不够平滑,可能存在移植物显形的问题,尤其是在皮肤较薄的患者中。 该研究旨在介绍一种“超碎的颗粒软骨移植”技术及其实现方法,以消除鼻整形术中切碎软骨存在的问题,并与游离切块软骨移植技术进行比较。 封面 通过这项技术,可以获得非常小的软骨颗粒,几乎和软骨泥一样小(图1)。 图1软骨泥(下、左)、超碎的颗粒软骨(下、中)、颗粒软骨(下、右)的显微照片 该研究于2015年4月至2018年12月期间,给113例采用正常颗粒软骨移植技术,给104例患者用超碎的软骨移植,对使鼻背更加光滑平整,或抬高山根或鼻背。双盲分析整形外科医生的手术记录、隆鼻效果评价问卷、触诊试验、术后即刻照片及术后1年照片在手术台上的评价。 在移植物可见性和骨吸收方面,超碎的颗粒软骨似乎优于颗粒软骨移植。除此外,根据美容和功能评定结果,第1组满意率为80.9%,第2组为90.6%。游离软骨移植时间5.6~15.4min,平均10mi
