环杓关节脱位指杓状软骨受外力影响失去正常的解剖位置,与环状软骨只有部分接触或完全分离,从而造成声带运动障碍,引起发声困难以及咽痛、呛咳等表现。该疾病在1973年被首次报道,临床上相对比较少见,发病率<0.1%~([1]),多由暴力或不熟练的气管插管引起,也有一部分病例有颈部外伤病史。近年来环杓关节脱位发病率逐渐增高,有分析认为可能与全麻手术增多、气管插管比例升高有关,也和不熟练的麻醉操作增多有很大关系。此 Cricoid diplomatosis dislocation refers to the external force of the arytenoid cartilage loss of normal anatomical location, and only partial contact with or completely separated from the cricoid cartilage, resulting in vocal cord dyskinesia, causing vocal dysarthria and sore throat, cough and other performance. The disease was first reported in 1973 and was relatively uncommon clinically, with a morbidity of <0.1% ~ ([1]), mostly caused by violent or unskilled tracheal intubation, and in some cases with a history of neck trauma. In recent years, the incidence of Crosophila joint dislocation gradually increased, some analysts believe that may increase with general anesthesia, tracheal intubation is related to an increase, but also inexperienced anesthesia operation has a lot to increase. this
