在离门齿18～22cm 也就是相当于环咽肌和上部食管括约肌的部位,存在一个腔内压增高区,为了探索此区的压力变化与喉手术后吞咽功能的关系,作者对6例正常人及13例部分喉切除术(8例伴环咽肌切开术;5例不伴环咽肌切开术)患者的上部食管括约肌腔内压力作了压差的研究。测压法系用一个6mm 粗的六腔聚乙烯导管,在距管端5cm 的圆周上,每隔60°有一个约3mm~2大小的测压孔,每孔各通入一腔,每
In 18 ~ 22cm away from the incisors, which is equivalent to the cricopharyngeal and upper esophageal sphincter site, there is an increase of intracavitary pressure area, in order to explore the pressure changes in this area and laryngeal surgery swallowing function, the author of 6 normal subjects And 13 cases of partial laryngectomy (8 cases with cricopharyngeal myocutomy; 5 cases without cricopharyngectomy) in patients with upper esophageal sphincter pressure was made for the study of pressure. Manometry with a 6mm thick six-chamber polyethylene catheter at a distance of 5cm from the tube end, every 60 ° there is a pressure measuring hole about 3mm ~ 2 size, each hole into a cavity, each
