title: [Change of cricoarytenoid joint after recurrent laryngeal nerve damaged].
abstract: The arytenoid mobilities and histological changes of cricoarytenoid (CA) joints were observed in 1, 2, 4, 6, 8, 10, 12 months after the injury of recurrent laryngeal nerve (RLN). Eighteen adult dogs were randomly divided into three groups: 1. Unilateral RLN partial damaged (4/18), 2. Unilateral RLN complete damaged (7/18), 3. Bilateral RLN damaged (7/18). The results demonstrated that arytenoid mobilities return to normal and no fibroses of CA joints were found in 6 months after RLN injury in group one. The arytenoid fixations were found in 6 and 4 months after RLN injury in group two and three, respectively. The fibroses of CA joints were more severe in group three than group two after RLN injury.
