内眦韧带的解剖研究及其在内眦赘皮矫正术中的应用

Anatomic study of medial canthal ligament and its application in Epicanthoplasty

目的:通过解剖观察测量和组织学观察内眦部解剖结构,探寻内眦赘皮矫正术术后并发症产生原因和可能的解决办法。方法:对9具尸头内眦部进行解剖观察并进行测量;对内眦韧带标本纤维走形进行组织学观察。结果:内眦韧带前支平均长0.834cm,上支平均长0.641cm,前支止点距内眦动静脉为0.079cm,前支起点距降眉肌为0.744cm。结论:内眦赘皮是由内眦韧带至皮肤纤维连接及眼轮匝肌错构形成,内眦赘皮矫正术应充分注意内眦赘皮产生的解剖原因。

Objective Through the anatomy gross dissection, measurement and histologic examination were taken on medial canthal ligament （MCL） which would explore the reason about the complication of epicanthoplasty and find the possible method to resolve it. Methods Gross dissection were performed on the medial canthal region and measurements of the medial canthal region were made on 9 preserved cadaver. The course of the fibers of the medial canthal ligament was observed through histological examination. Results The anterior branch of the medial canthal ligament averaged 8.34mm in length. The superior branch of the medial canthal ligament averaged 6.41 mm in length. The distance from the insertion of the anterior branch of the medial canthat ligament to the angular artery and the angular vein was 0.79mm. The distance from the impetus of the anterior branch of the medial canthal ligament to depressor supercilii was 7.44mm Conclusion Epicanthus was confusedly and disorderly composed of the fibers from the medial canthal ligament to the skin and the orbicularis oculi. The reason of epicanthus should be taken attention into the epicanthoplasty.
