Laryngeal joint injury or cricoarytenoid dislocation is a relatively rare laryngologic finding, according to the international medical literature. It may occur as a result of external neck trauma or more frequently as a result of intubation. Chief symptoms are hoarseness, vocal fatigue, and loss of voice control.
Between 1993 and 1997 we diagnosed an arytenoid dislocation in 2 female and 5 male patients, in every case the etiology was an intubation trauma. Videolaryngoscopic recording was the most useful aid in diagnosis.
Six patients were treated with closed reduction surgery between 8 and 49 days after dislocations. Normal voice was restored in four patients, and in one patient as late as 49 days after the dislocation. One patient had an additional recurrent nerve paralysis.
Our results suggest that a closed reduction of the arytenoid luxation can be successful even several weeks after the injury.
根据国际医学文献，喉关节损伤或环杓关节脱位是一种相对罕见的喉科病症。它可能因颈部外部创伤引起，或更常见的是因插管导致。主要症状为声音嘶哑、发声疲劳和声音控制丧失。
1993年至1997年间，我们诊断出2名女性和5名男性患者发生了杓状软骨脱位，每例病因均为插管创伤。电子喉镜记录是诊断中最有用的辅助手段。
6例患者在脱位后8至49天接受了闭合复位手术。4例患者恢复了正常嗓音，其中1例患者在脱位后49天才恢复。1例患者出现了额外的喉返神经麻痹。
我们的结果表明，即使在损伤数周后，杓状软骨脱位的闭合复位仍可能成功。
