An infectious or inflammatory response with ongoing ulceration or granulation on the superstructure of the arytenoid cartilage. Here we are talking of the arytenoid cartilage and/ or its thin “envelope” of fibrous tissue called perichondrium. The root chondr- refers to cartilage.
A similar and much more common disorder, contact granuloma or contact ulcer, occurs on the medial surface of the arytenoid cartilage, but low and at the level of the vocal process. When arytenoid chondritis or perichondritis occurs, it causes significant chronic pain (in contrast to contact granuloma, which can be pain-free or bring only minor discomfort). We have never diagnosed the underlying cause. Treatment tends to require definitive removal of the area of cartilage involved (not the entire arytenoid, of course), and then typically the area will heal, though often only after a time of re-granulation.
