结节性软骨皮炎

定义

影响外耳的一种常见的压力引起的疼痛性结节或溃疡。其形成是由于皮肤和下层软骨因卧床头部重量造成高压焦点缺血引起。受累部位取决于耳廓形状（最常见的是耳廓螺旋受累，但有些人是耳廓反螺旋线更突出），以及患者是否仅限于单侧睡眠，因此无法避免卧床时耳朵承受持续压力。

A common pressure-induced painful nodule or ulcer affecting the external ear. It results from ischaemia of skin and underlying cartilage from a focal point of high pressure from the weight of the recumbent head. The site of involvement is dependent on the shape of the pinna (most commonly the helix is involved but in some individuals it is the antihelix which is more prominent) and whether the sufferer is limited to sleeping on one side and is thus unable to spare the ear from constant pressure when lying in bed.
