This report describes the occlusion and craniofacial morphology--together with changes in tongue activity during swallowing before and after surgical correction--in a 26-year-old female patient with unilateral cleft lip and palate. Cross-bites were not observed before or after repair. Lateral cephalometric findings revealed a convex profile with a normal anterior cranial base length, a flat mandibular plane, and a short lower-anterior face height. Preoperative cineradiographic appraisal showed atypical tongue activity during swallowing. The dorsum of the tongue remained high to seal the cleft. The bolus was kept on the floor of the mouth and passed along the lateral margins of the tongue. The swallow duration, as determined by EMG of the tongue, was extremely long when compared with infant-operated cleft lip and palate patients and to noncleft subjects. Postoperatively, tongue function was similar to that in both cleft patients in whom closure was performed in infancy and to noncleft controls.
本报告描述了一名26岁单侧唇腭裂女性患者手术矫正前后的咬合及颅面形态，以及吞咽过程中舌活动的变化。修复前后均未观察到反咬合。头颅侧位测量结果显示，面部轮廓凸出，前颅底长度正常，下颌平面平坦，下前脸高度较短。术前动态X线评估显示吞咽时舌活动异常。舌背保持高位以封闭裂隙。食团停留在口腔底部并沿舌的外侧边缘通过。与婴儿期接受唇腭裂手术的患者及非腭裂受试者相比，通过舌肌电图测定的吞咽持续时间极长。术后，舌功能与婴儿期接受腭裂修复的患者及非腭裂对照组相似。
