BACKGROUND
The pathogenesis of otitis media is related to Eustachian tube dysfunction. The tensor veli palatini muscle actively opens the Eustachian tube and promotes middle-ear ventilation. This study describes a technique for paratubal electromyography that uses a surface, non-invasive electrode able to record tensor veli palatini muscle activity during swallowing.
METHODS
Twenty otitis media patients and 10 healthy patients underwent tensor veli palatini electromyography. Activity of this muscle before and after Eustachian tube rehabilitation was also assessed.
RESULTS
In 78.5 per cent of patients, the electromyography duration phase and/or amplitude were reduced in the affected side. The muscle action potential was impaired in all patients who underwent Eustachian tube rehabilitation.
CONCLUSION
This study confirmed that Eustachian tube muscle dysfunction has a role in otitis media pathogenesis and showed that muscle activity increases after Eustachian tube rehabilitation therapy.
背景
中耳炎的发病机制与咽鼓管功能障碍有关。腭帆张肌可主动打开咽鼓管并促进中耳通气。本研究描述了一种用于咽鼓管旁肌电图检查的技术，该技术使用一种表面无创电极，能够在吞咽过程中记录腭帆张肌的活动。
方法
20例中耳炎患者和10例健康患者接受了腭帆张肌肌电图检查。还评估了咽鼓管功能恢复前后该肌肉的活动情况。
结果
78.5%的患者患侧肌电图持续时间阶段和/或幅度降低。所有接受咽鼓管功能恢复治疗的患者肌肉动作电位均受损。
结论
本研究证实咽鼓管肌肉功能障碍在中耳炎发病机制中起作用，并表明咽鼓管功能恢复治疗后肌肉活动增加。
