内窥镜辅助下对隆鼻隧道的观察

Observe the dissection of the tunnels of augmentation rhinoplasty under endoscope

目的了解隆鼻术盲操作制作隧道的解剖情况。方法通过内窥镜对盲操作制作的隧道进行观察。结果①有错层分离现象,易形成假道;②有鼻软骨中线分离现象;③隧道中存在索带或局限性间隔;鼻翼软骨表面有两条静脉,梨状孔缘有垂直穿出的血管;④单侧鼻孔缘弧形切口入路多半存在隧道左右边界不对称。结论盲操作制作的隧道多数存在解剖不到位、索带或间隔等问题,可能是导致隆鼻术后一些并发症的原因。

Objective To observe and analyse the dissection of the tunnels in traditional blind operation of augmentation rhinoplasity. Methods 11 Cases of augmentation rhinoplasity were collected and be observed by an endoscope as soon as the tunnels were fomed during the operations. Results ①Some of the tunnels did not go through one layer. ②The bilateral cartilage separated in the mid-line. ③There were two blood vessels in the surface of alar cartilage.There were perforating blood vessels in the edge of pyriform aperture. ④In some cases whose incision were in unilateral alar margin, the tunnel were asymmetric. Conclusion In some cases of traditional blind operation of augmentation rhinoplasty, tunnels were not suitable, they were asymmetric; and there were desmo and septa in the tunnels. Those might be the causes of complications post-op of augmentation rhinoplasty.
