BACKGROUND
Combined surface electromyography (sEMG) and visual analogue scale (VAS) pain assessment was performed on randomly assigned adults following tonsillectomy to research the effect of fibrin sealant (Group 1, n = 25), CO(2) laser (Group 2, n = 18) and electrocoagulation (Group 3, n = 40) on postsurgical pain.
METHODS
Timing and amplitude of sEMG activity of masseter, infrahyoid and submandibular muscles were measured during swallowing simultaneously with VAS assessment and compared to normative database.
RESULTS
Postsurgical electric activity of masseter and infrahyoid was significantly higher in comparison with normative database. sEMG and VAS data showed that tonsillectomy ended with fibrin sealant caused less pain than laser or electrocoagulation techniques with no correlation between the VAS score and duration of swallows.
CONCLUSION
Tonsillectomy affects muscle activity significantly by involving additional muscles (infrahyoid) in swallowing. Combined sEMG and VAS data indicated electrocautery as the most painful, laser as less painful, and fibrin sealant as the least painful technique.
背景
对随机分组的扁桃体切除术后成年人进行表面肌电图（sEMG）和视觉模拟评分（VAS）疼痛评估，以研究纤维蛋白封闭剂（第1组，n = 25）、二氧化碳激光（第2组，n = 18）和电凝术（第3组，n = 40）对术后疼痛的影响。
方法
在吞咽过程中测量咬肌、舌骨下肌和下颌下肌的sEMG活动的时间和幅度，同时进行VAS评估，并与标准数据库进行比较。
结果
与标准数据库相比，术后咬肌和舌骨下肌的电活动明显更高。sEMG和VAS数据显示，使用纤维蛋白封闭剂进行扁桃体切除术引起的疼痛比激光或电凝术少，VAS评分与吞咽持续时间之间无相关性。
结论
扁桃体切除术通过使吞咽过程中涉及额外的肌肉（舌骨下肌）而显著影响肌肉活动。sEMG和VAS数据联合表明，电灼术是最疼痛的技术，激光次之，纤维蛋白封闭剂是最不痛的技术。
