Seventeen patients with dimples, fistulae and cysts in the region of the cheek and the preauricular field are reported. All are located in the neighborhood of the dorsal end of the first visceral arch. Both the fistulae of the ascending helix and the upper preauricular fistulae must be regarded as relics of the dorsal end of the first branchial cleft. This interpretation supports the theory of Wood-Jones and I-Chuan according to which the tragus is formed from the material of the mandibular arch, and the remaining part of the auricle from the mesoderm of the second visceral arch. Similar anomalies in the neighborhood of the angle of the mouth, the extraoral opening of an accessory duct of Stensen and the inferior preauricular fistula are sufficiently explained by the incomplete closure or tearing of the embryonal oral aperture.
报告了17例在脸颊和耳前区域有酒窝、瘘管和囊肿的患者。所有病变均位于第一鳃弓背端附近。耳轮上升部瘘管和耳前上部瘘管均应视为第一鳃裂背端的遗迹。这一解释支持了伍德 - 琼斯和伊川的理论，根据该理论，耳屏由下颌弓的物质形成，耳廓的其余部分由第二鳃弓的中胚层形成。口角附近的类似异常、斯滕森副导管的口外开口以及耳前下部瘘管，可通过胚胎口腔孔的不完全闭合或撕裂得到充分解释。
