目的采用蛙股肌模型，通过对比实验研究扩张括约肌咽成形术（ESP）和倒刺咽成形术（BRP）对肌张力和肌纤维撕裂的影响。方法采用蛙股肌进行实验研究。倒刺缝线用于模拟BRP咽成形术，而Vicryl 3-0缝线用于模拟ESP技术。缝线的另一端连接到牵引秤上。牵引量表用于测量相对于获得肌肉断裂所需的力的重量。两种手术技术都在青蛙肌肉上模拟。进行牵引，直到观察到肌肉断裂，测量获得肌肉断裂所需的力的值。结果在ESP模拟实验中，平均牵引力为0.7kg时，标本肌肉发生断裂。结论在模拟ESP技术时，平均牵引力低于BRP技术时，标本肌肉发生断裂。在牵引过程中，BRP的多个侧向支撑缝合环可以确保比ESP的单牵拉头缝合更大的稳定性，肌纤维损伤的风险较小。
Purpose To show the different effects of expansion sphincter pharyngoplasty (ESP) and barbed reposition pharyngoplasty (BRP) on muscle tension and muscle fiber tearing using a comparative experimental stress test with a frog thigh muscle model. Methods Frog thigh muscle was used for this experimental study. A Barbed suture was used to simulate the BRP pharyngoplasty whereas a Vicryl 3-0 suture was used to simulate the ESP technique. The other extremity of the suture was attached to traction scales. The traction scales were used to measure the weight relative to the amount of force required to obtain muscle breaking. Both surgical techniques were simulated on the frog muscle. Traction was performed until muscle breaking was observed, measuring the value of force needed to obtain muscle rupture. Results Specimen muscle breakdown in the ESP simulation occurred with an average value of 0.7 kg of traction force. Contrarily, specimen muscle breakdown in the BRP simulation with Barbed suture occurred with an average value of 1.5 kg of traction force Conclusion During simulation of the ESP technique, specimen muscle breakdown occurred with an average value of traction force lower than in the BRP technique. During traction the multiple lateral sustaining suture loops of BRP could ensure greater stability then the single pulling tip suture of ESP with minor risk of muscle fiber damage.
