Bleeding within the supraglottic region can be a lethal complication after CO(2) laser microsurgery. Our aim was to propose endoluminal anatomical landmarks to locate the superior laryngeal vessels resulting in a safer microsurgery.
Endoluminal dissections were made in 22 larynges without laryngeal disease.
The neurovascular structures were in the superior third of a triangle defined by the vocal process, the anterior commissure, and the epiglottic attachment of the aryepiglottic fold. They overlapped in 4 different ways: pattern I (70.4%): superior laryngeal vein (SLV), superior laryngeal artery (SLA), and internal laryngeal nerve (ILN); pattern II (13.6%): SLA, SLV, ILN; pattern III (4.6%): SLV, ILN, and SLA; pattern IV (4.6%): SLA, ILN, and SLV.
Microsurgery in the supraglottic region may be safer if surgeons are aware of the superior third of the above-defined triangle, "danger area", where the vascular elements of this region are located.
CO2 激光显微手术后，会发生声门上区出血，这是一种致命的并发症。我们的目的是提出腔内解剖标志，以定位喉上血管，从而使手术更安全。
在 22 个无喉部疾病的喉中进行腔内解剖。
神经血管结构位于由杓状软骨、前联合和会厌舌面附着处构成的三角形的上三分之一处。它们以 4 种不同方式重叠：模式 I（70.4%）：喉上静脉（SLV）、喉上动脉（SLA）和喉内神经（ILN）；模式 II（13.6%）：SLA、SLV、ILN；模式 III（4.6%）：SLV、ILN、SLA；模式 IV（4.6%）：SLA、ILN、SLV。
如果外科医生了解上述定义的三角形的上三分之一，即“危险区”，该区域的血管元素位于此处，那么在声门上区进行显微手术可能会更安全。
