2024年5月17日 · Antihelix: This is a Y-shaped ridge inside the helix that follows the outer curve of the ear. Crux helix: This C-shaped ridge extends from the top of the helix to the bottom of the antihelix. Tragus and antitragus: These are smaller ridges of cartilage that encircle the ear canal.

2020年8月16日 · A second innermost curvature runs in parallel with the helix – the antihelix. The antihelix divides into two cura; the inferoanterior crus, and the superoposterior crus. In the middle of the auricle is a hollow depression, called the concha .

Antihelix: A Y-shaped curved cartilaginous ridge arising from the antitragus and separating the concha, triangular fossa, and scapha. The antihelix represents a folding of the conchal cartilage and it usually has similar prominence to a well-developed helix.

2024年5月17日 · Common anatomical variants of the antihelix include 1: supernumerary crus (Stahl ear), in which there is an additional ridge or crus to the superior and inferior crus. angled antihelix where a steep angle is observed typically at the level of the antitragus instead of a smooth gentle curve. prominent superior or inferior crus

2017年3月28日 · The antihelix is a Y-shaped curved cartilaginous ridge arising from the antitragus and separating the concha, triangular fossa, and scapha/scaphoid fossa (Figure 3). The antihelix represents a folding of the conchal cartilage and it usually has similar prominence to a well-developed helix.

Superiorly, the antihelix divides into a superior and inferior crus, which surround the fossa triangularis. The depression between the helix and antihelix is known as the scapha or scaphoid fossa. The antihelical fold surrounds the concha, a deep cavity posterior to …
