对拔除下第三和第二磨牙后的 40 名成年患者进行表面肌电图 (sEMG) 研究，以研究 sEMG 评估其吞咽痛症状的方法和局限性。吞咽和饮水期间评估的参数包括时间、每 100 cc 水的吞咽次数以及 m 的肌电图活动范围（幅度）。咬肌、舌骨下肌群和颏下颌下肌群。上述变量（平均值+标准差）是针对牙科患者组（n = 40）和健康成人对照组（n = 40）进行测量的。所有测试中吞咽和饮酒的持续时间均显示牙科患者组有所增加，其中这种趋势具有统计学意义。两组连续饮酒期间男性和女性成年人的肌肉活动持续时间和幅度没有统计学上的显着差异（p = 0.05）。 m 的电活动平均值（以 μV 为单位）。与对照组相比，牙科患者组的咬肌明显较低。两组颏下-颌下肌群和舌骨下肌群的电活动相同。吞咽表面肌电图是一种简单可靠的无创方法，用于评估拔牙后的吞咽疼痛/吞咽困难症状，检查不适程度较低。表面肌电图研究证明拔牙磨牙术后吞咽困难源于口腔，不影响咽段和颏下颌下肌群。此类吞咽困难有明显的肌电图征象：单次吞咽持续时间延长、饮水时间延长、m电活动范围低。咬肌、颏下颌下肌群的正常活动范围以及“干吞咽”后遗症。这些数据可用于评估主诉和症状，以及用于术前和术后阶段的比较以及术后口腔不适和吞咽困难治疗期间的肌电图监测。
Surface electromyographic (sEMG) studies were performed on 40 adult patients following extraction of lower third and second molars to research the approach and limitations of sEMG evaluation of their odynophagia complaints. Parameters evaluated during swallowing and drinking include the timing, number of swallows per 100 cc of water, and range (amplitude) of EMG activity of m. masseter, infrahyoid and submental-submandibular group. The above mentioned variables (mean + standard deviation) were measured for the group of dental patients (n = 40) and control group of healthy adults (n = 40). The duration of swallows and drinking in all tests showed increase in dental patients' group, in which this tendency is statistically significant. There was no statistically significant difference between male and female adults' duration and amplitude of muscle activity during continuous drinking in both groups (p = 0.05). The mean of electric activity (in μV) of m. masseter was significantly lower in the dental patients' group in comparison with control group. The electric activity of submental-submandimular and infrahyoid muscle groups was the same in both groups. Surface EMG of swallowing is a simple and reliable noninvasive method for evaluation of odynophagia/dysphagia complaints following dental extraction with low level of discomfort of the examination. The surface EMG studies prove that dysphagia following dental extraction and molar surgery has oral origin, does not affect pharingeal segment and submental-submandibular muscle group. This type of dysphagia has clear EMG signs: increased duration of single swallow, longer drinking time, low range of electric activity of m. masseter, normal range of activity of submental-submandibular muscle group, and the "dry swalow" aftereffect. The data can be used for evaluation of complaints and symptoms, as well as for comparison purposes in pre- and postoperative stages and in EMG monitoring during treatment of post-surgical oral cavity discomfort and dysphagia.
