The petrified auricle is a clinical entity in which the auricle, in part or total, has become stone-hard and moves as a rigid unit. This uncommon condition is most often due to ectopic calcification of the auricular cartilage. It may occur as a result of local trauma, in association with various systemic diseases such as Addison's disease, hypopituitarism, thyroid or parathyroid disorders, or following radiation therapy. Auricular ossificans (ectopic ossification) is a rare phenomenon in which the rigidity of the petrified ear is due to replacement of the elastic cartilage by bone. In the literature there are presently nine cases documented histologically. Two more cases are reported here. In most cases, the auricular changes are preceded by acute, severe hypothermia (frostbite). Exostoses of the external auditory canal is another disease of the external ear in which the proliferation of bone follows chronic mild hypothermia of the external auditory canal caused by exposure to cold water while surfing. It is postulated that if surfers who have developed exostoses of the external auditory canal from the cold water continue to enjoy such littoral activities, ossification of the auricle may also occur.
石化耳廓是一种临床病症，其中耳廓部分或全部变得像石头一样坚硬，并作为一个刚性单元移动。这种罕见的情况通常是由于耳廓软骨的异位钙化。它可能因局部创伤、与各种全身性疾病（如艾迪生病、垂体功能减退、甲状腺或甲状旁腺疾病）相关或放疗后而发生。耳廓骨化（异位骨化）是一种罕见现象，其中石化耳的僵硬是由于弹性软骨被骨替代所致。目前文献中有9例经组织学记录。本文报告另外2例。在大多数情况下，耳廓变化之前有急性、严重的体温过低（冻伤）。外耳道外生骨疣是外耳的另一种疾病，其中骨的增殖是由于冲浪时接触冷水导致外耳道慢性轻度体温过低引起的。据推测，如果因冷水而患上外耳道外生骨疣的冲浪者继续进行此类沿海活动，耳廓也可能发生骨化。
