环杓关节是一滑液囊关节,因此能影响滑液囊关节的疾病都能累及它。但对神经失去作用后长时间固定的环杓关节,从未被研究过,本文目的是想明确环杓关节能否影响喉机能的恢复。方法:选用Sprague-Dawley鼠,给乙醚麻醉,在解剖显微镜下,解剖鼠的颈部达气管食管沟,于环状软骨到第五气管环之间毁坏此处的神经。当此处神经被毁坏时,全部试验动物都发生暂时性喘鸣。在一只鼠身上作一假手术——不破坏此处的神经,不伤及气管食管沟,该鼠未发生喘鸣。将试验鼠分别在术后第2、4、6、12、21、26、48周杀死。假手术的鼠在30周杀死,
The cricoid joint is a synovial joint that affects the joints of the synovial sac and affects it. However, the long-time fixed cricoarytenoid joint that has lost its effect on the nerve has never been studied. The purpose of this paper is to find out whether the cricoaryal joint can affect the recovery of laryngeal function. METHODS: Sprague-Dawley rats were used to anesthetize the ether. Under the dissecting microscope, the neck of the rats was dissected to reach the trachea of the trachea and the nerves were destroyed between the annular cartilage and the fifth tracheal ring. When the nerves were destroyed here, all the test animals had transient wheezing. A sham operation was performed on a rat - without damaging the nerves here and without trauma to the tracheal esophageal groove, without wheezing. The mice were killed at 2, 4, 6, 12, 21, 26, 48 weeks after operation. Sham-operated rats were killed at 30 weeks,
