Objective: To study the influence of amputating cricopharyngeal muscle and unilateral pharyngeal constrictor after total laryngectomy on vocal restoration. 目的:探讨全喉切除发音重建中切断环咽肌与一侧咽缩肌对发音的影响。
Video fluoroscopic ( VF) showed that the cricopharyngeal muscle can open normally when the food went through. 吞咽造影复查显示在食团通过时,环咽肌正常开放,误吸消失。
The cricopharyngeal muscle, a component of the inferior constrictor, forms the muscular orifices of the esophagus. 环状咽肌是肌下缩肌中的一个组织,形成食道的肌肉。
Under videofluoroscopy, 9 patients showed significantly decreased larynx elevation. Ten patients opened the cricopharyngeal muscles insufficiently, while two could not open at all. 电视透视检查显示,患者口期吞咽均未见明显损伤,9例患者喉结构上抬幅度明显减弱,10例患者环咽肌打开不能,2例患者打开不全,12例患者喉穿透等。
Methods Two cases of dysphagia ( one caused by radiation encephalopathy and the other by brain stem infarction) were diagnosed as cricopharyngeal achalasia through a videofluoroscopic swallowing study ( VFSS) and a fiberoptic endoscopic evaluation of swallowing ( FEES). 方法放射性脑病、脑干梗死伴吞咽障碍患者各1例,经吞咽X线荧光透视检查和光纤内窥镜吞咽检查,拟诊环咽肌失弛缓症。
The incidence of cricopharyngeal bar in patients with dysphagia 吞咽功能障碍患者环咽肌切迹的出现率
There were three muscles in the pharyngoesophageal region: the thyropharyngeal ( TP), cricopharyngeal ( CP) and circular esophageal muscles. 在食管上括约肌区包括甲咽肌、环咽肌和近端食管环形肌三部分。
Therefore cricopharyngeal myotomy is a simple and effective method to prevent spastic dysphonia. 表明术中切断环咽肌是预防发音钮术后痉挛性发音障碍的一种简便而有效的方法。
Dissociating tracheoesophageal wall too much and incising cricopharyngeal muscle incompletely resulted in surgery failure. Ⅰ期手术失败2例,与气管食管壁分离过多有关;Ⅱ期手术失败1例,系环咽肌切断不完全所致。
Compared with that of volunteers, height and velocity of larynx elevation decreased, opening width of cricopharyngeal muscle reduced and swallowing latency prolonged in dysphagia patients. 与正常组对照,误吸组喉上抬幅度、速度降低,环咽肌打开宽度减少,吞咽潜伏期延长。
