Labiaplasty has become a rather common operation. The main complication of the different surgical techniques is the dehiscence of the suture line. The dehiscence rate varies among the different techniques, and this may imply that the vascular anatomy is not respected in some cases. The detailed arterial anatomy of labia minora is not well described, so the aim of the authors was to describe this anatomy with a cadaveric study.
Eleven fresh cadavers were dissected, and arterial study was made with injected computed tomography scans and rotational angiography. At the end, a cast of the arterial network was made and chemically exposed to verify the radiological findings.
The findings of this study allowed identification of a dominant central artery that was named "C" artery, two posterior arteries named "P1" and "P2," and one small anterior artery, "A." Furthermore, a connection between the anterior system of the external pudendal artery and the posterior system of the internal pudendal artery was confirmed.
The arterial network of the labia minora was identified with this study. This may help surgeons orientate the wedge excision when they perform labiaplasties. More precisely, when this wedge is placed at the most anterior part of the labia minora, the least perfused area is removed, and a posterior flap is created that will preserve a robust blood perfusion.
阴唇整形术已成为一种相当常见的手术。不同手术技术的主要并发症是缝线裂开。不同技术的裂开率不同，这可能意味着在某些情况下没有尊重血管解剖结构。小阴唇的详细动脉解剖结构描述得并不清楚，因此作者的目的是通过尸体研究来描述这种解剖结构。
对 11 具新鲜尸体进行解剖，并通过注射计算机断层扫描和旋转血管造影进行动脉研究。最后，制作了一个动脉网络的铸型，并进行化学暴露以验证放射学发现。
本研究的结果允许识别一条称为“C”动脉的主导中央动脉，两条后动脉分别称为“P1”和“P2”，以及一条小的前动脉“A”。此外，还证实了阴部外动脉前系统与阴部内动脉后系统之间的连接。
本研究确定了小阴唇的动脉网络。这可能有助于外科医生在进行阴唇整形术时指导楔形切除。更准确地说，当这个楔形物放置在小阴唇的最前部分时，切除的是血流灌注最少的区域，并创建一个后部皮瓣，以保持强大的血液灌注。
