EMG activity of the upper lip was measured with bipolar surface electrodes during speech and nonspeech tasks in order to assess labial function in subjects with repaired clefts. Eighteen patients between 15 and 23 years of age with repaired unilateral cleft lip (isolated or combined with repaired cleft palate) were compared to 24 matched noncleft subjects. Data analysis demonstrated that the amplitude of action potentials of the upper lip was significantly greater in the cleft group. We hypothesize that the enhanced activity of the repaired upper lip during function may contribute to the facial growth abnormalities usually seen in the cleft population.
为了评估唇裂修复患者的唇部功能，在言语和非言语任务期间，使用双极表面电极测量上唇的肌电图活动。将18名年龄在15至23岁之间的单侧唇裂修复患者（单纯唇裂或合并腭裂修复）与24名匹配的非唇裂受试者进行比较。数据分析表明，唇裂组上唇动作电位的幅度明显更大。我们推测，修复后的上唇在功能期间活动增强可能导致唇裂人群中常见的面部生长异常。
