The aim of the study was to examine the position and function of the tongue in cleft lip and palate (CLP) patients and to reveal their impact on alveolar bone development. Two hundred and fifty-eight CLP children and 50 healthy children as control group were included in the study. Tongue function and position were assessed by ultrasound examination. In CLP patients the dorsum of the tongue was deformed and the asymmetry of some tongue structures was also found out (mainly the massive of the tongue muscles). Low tip and high dorsum position were specific for CLP children as well as discoordinated tongue movements. Both in static and dynamic condition the tongue was pressed to the lower alveolar bone thus disturbing its development. The obtained data showed tongue position and function to be one of the causes for lower promacrognathy and lingual inclination of incisors in CLP patients. The absence of tongue impact on the upper alveolar bone should be seen as one of the factors for upper retromicrognathy.
该研究的目的是检查唇腭裂（CLP）患者舌头的位置和功能，并揭示其对牙槽骨发育的影响。该研究纳入了258名CLP儿童和50名健康儿童作为对照组。通过超声检查评估舌头功能和位置。在CLP患者中，发现舌背变形，还发现一些舌结构不对称（主要是舌肌团块）。舌尖低位和舌背高位以及不协调的舌运动是CLP儿童的特征。在静态和动态情况下，舌头均被压向较低的牙槽骨，从而干扰其发育。获得的数据表明，舌头的位置和功能是CLP患者下颌前突不足和切牙舌倾的原因之一。舌头对上颌牙槽骨无影响应被视为上颌后缩小颌畸形的因素之一。
