Arytenoid cartilage dislocation is a known complication of tracheal intubation and is also a type of laryngeal injury. Although spontaneous recovery has been reported, most patients require reduction via pharyngoscopy under general or neuroleptic anesthesia, and some must be treated by open reduction such as laryngoplasty. We report 8 cases of arytenoid cartilage dislocation between August 2003 and August 2004. Excluding 3 patients who recovered spontaneously, we conducted reduction under local anesthesia as an ambulatory procedure in the other 5 with anterior dislocation, i.e., 2 men and 3 women aged 53 to 75 years old. Of these 5, dislocation occurred after tracheal intubation in 4, and in 1 after wearing a laryngeal mask. The outcome was favorable in all 5. Surgery was conducteded after a fiberscope was inserted nasally and a urethral balloon catheter was inserted via the other nasal cavity under topical anesthesia with 4% lidocaine for both nasal cavities and the larynx. While monitoring the larynx, we expanded the balloon and pulled it away from the glottis. The expanded balloon was then placed at the arytenoid region for a few seconds. This procedure was repeated several times to achieve reduction. Three patients recovered well within 1 to 2 weeks of the first reduction, while 2 requierd a second reduction because of insufficient improvement after the first. These two both showed improved vocal cord movement and recovery from hoarseness within 1 to 2 weeks after the second reduction. We conducted 7 reductions without complications in any patient. Our approach is usable in the ambulatory setting, and is simple, minimally invasive, and effective. We consider it to be useful treatment for anterior arytenoid cartilage dislocation.

Arytenoid cartilage dislocation has traditionally been relatively rare; however, recently cases caused by endotracheal intubation appear to be increasing. Arytenoid cartilage dislocation can occur anteriorly or posteriorly during the process of intubation. Here, we dealt with two cases of arytenoid dislocation occurring anteriorly and posteriorly after general anesthesia.Case 1: A 47-year-old woman underwent an operation for breast cancer under general anesthesia. She suffered hoarseness immediately following intubation and it continued for two months. Videolaryngoscopic examination revealed fixation of the right vocal fold and electromyography revealed electrical activity in the right thyroarytenoid muscle during phonation. We diagnosed right anterior arytenoid cartilage dislocation and undertook manual reduction by laryngomicrosurgery. Postoperatively the patient's hoarseness began to improve gradually and ultimately resulted in improvement of the right anterior arytenoid cartilage dislocation after a period of six months.Case 2: A 35-year-old male underwent an operation for hepatic hematoma under general anesthesia. Hoarseness was noted immediately after intubation and it continued for one 熊本大学耳鼻咽喉科頭頸部外科：〒860-8556 熊本県熊本市本荘１丁目１番１号
