Video demonstrating inability to compress the left external ear on palpation. The ears demonstrated rock-hard stiffening of the left external ear, at the helix and antihelix, while the earlobe remains unaffected. The right ear exhibited similar findings.

视频展示在触诊过程中无法压缩左侧外耳的情况。左侧外耳呈现岩石般坚硬的僵硬，位于耳轮和反耳轮处，而耳垂则未受影响。右侧耳表现出类似发现。
