Abstract

Background: The superior auricular artery (SAA)-retroauricular flap is commonly used for the repair of defects of the superior auricle. There are few studies about the anatomy of the SAA.

Objective: This study mainly analyzed the anatomical pattern of SAA.

Materials and methods: Computed tomography (CT) was performed on 26 cadaver heads infused with lead oxide. The anatomical pattern of the SAA was statistically analyzed by 3-dimensional CT images.

Results: The SAA was classified into 3 types according to whether it gave off the helix branch or the auricular dorsal branch. The SAA was located mainly in an area 2 cm above and below the horizontal line at the midpoint of the 2 base points (the otobasion superius and the apex of the external auditory canal). The origin of each branch of the SAA was mainly located in Areas 2, 3, and 4 within a circular area that had the otobasion superius as the center of the circle and a radius of 2 cm.

Conclusion: In this study, the 3 anatomical types and anatomical patterns of the SAA were identified. These findings can provide a reference for the design of SAA-retroauricular flaps and for surgical planning.

利用三维计算机断层扫描血管造影术对耳上动脉进行解剖学研究。

背景：耳廓上动脉（SAA）-耳廓后皮瓣常用于修复耳廓上部缺损。有关 SAA 解剖结构的研究很少：本研究主要分析 SAA 的解剖形态：对注入氧化铅的 26 个尸体头部进行了计算机断层扫描（CT）。通过三维 CT 图像对 SAA 的解剖形态进行统计分析：结果：根据SAA是否发出螺旋支或耳背支，将其分为3种类型。SAA主要位于两个基点（耳上窝和外耳道顶）中点水平线上下2厘米的区域。SAA各分支的起源主要位于第2、第3和第4区，该区域位于以耳后上腭为圆心、半径为2厘米的圆形区域内：本研究确定了 SAA 的 3 种解剖类型和解剖模式。结论：本研究确定了 SAA 的 3 种解剖类型和解剖模式，这些发现可为 SAA 后耳皮瓣的设计和手术规划提供参考。
