The aim of this cross-sectional study was to evaluate the electromyographic activity of the superior orbicularis oris muscle both in children surgically treated for bilateral complete cleft lip and palate (BCCLP) as well as in subjects without BCCLP. The study comprised 77 children aged 6.6 to 12.5 years. All the patients with clefts had previously undergone lip and palate surgery. The upper lip electromyographic (EMG) assessments were made with a DAB-Bluetooth device (Zebris Medical GmbH, Germany) at rest, while swallowing saliva, protruding lips and compressing lips. EMG measurements were also made when the subjects produced phonemes /p/, /b/, and /m/ with the vowel /a/. The Mann-Whitney U test was applied to statistically analyze the EMG values. Significantly higher median upper lip EMG activity under working conditions such as swallowing saliva, lip compression, and production of the phoneme /p/ with the vowel /a/ was observed in patients with BCCLP compared to those without a cleft. The results of the study showed that the upper lip muscle activity increases in children with BCCLP when swallowing saliva, compressing lips and during some speech movement tasks. This may be important in the aspect of the effect of surgical lip repair on the craniofacial growth.
这项横断面研究的目的是评估双侧完全性唇腭裂（BCCLP）手术治疗儿童以及无BCCLP受试者的口轮匝肌上部的肌电活动。该研究纳入了77名年龄在6.6至12.5岁之间的儿童。所有腭裂患儿此前均接受过唇腭裂手术。使用DAB蓝牙设备（德国Zebris Medical GmbH公司）在静息状态、吞咽唾液、噘唇和抿唇时对上唇进行肌电图（EMG）评估。当受试者发元音/a/的音素/p/、/b/和/m/时也进行EMG测量。采用曼-惠特尼U检验对EMG值进行统计学分析。与无腭裂者相比，BCCLP患者在吞咽唾液、抿唇以及发元音/a/的音素/p/等工作条件下，上唇EMG活动的中位数显著更高。研究结果表明，BCCLP患儿在吞咽唾液、抿唇以及一些言语运动任务期间，上唇肌肉活动增加。这在手术唇修复对颅面生长的影响方面可能具有重要意义。
