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 understand the anatomy of the tunnel made by blind operation of rhinoplasty. Methods Endoscopic blind tunnels were observed. Results ① There was a separation of the wrong layer, easy to form a false passage; ② there is the phenomenon of midline separation of the nasal cartilage; ③ There are cable or limited spacing in the tunnel; there are two veins on the surface of the alar cartilage; ; ④ unilateral nasal marginal arc incision approach the tunnel left and right sides of the border there is asymmetry. Conclusions Most tunnels made by blind operation have some problems, such as lack of anatomy, banding or spacing, which may be the reason of some complications after rhinoplasty.
