The facial musculature is part of a biocybernetic feedback system within the stomatognathic system, the continuity of which is disturbed by clefts of the lip, jaw, and palate (cheilognathopalatoschisis). This results in topographic, fine-structural and functional alterations of the facial musculature. In two heads with unilateral clefts and two heads with bilateral clefts, the facial musculature was dissected and the M. orbicularis oris macroscopically and topographically examined. We found changes in the attachment of the M. orbicularis oris. The modiolus, which is coresponsible for the proper topographic relation of the M. obicularis oris to the other facial muscles, was unchanged. Further, we examined the vascular system of the muscle, which likewise adapts to the altered situation. Lip/jaw/palatal clefts result in anatomically functional and fine-structural alterations of the M. orbicularis oris, while the rest of the facial musculature remains unchanged.
面部肌肉组织是口颌系统内生物控制论反馈系统的一部分，唇、颌和腭裂（唇颌腭裂）会破坏该系统的连续性。这会导致面部肌肉组织出现局部、细微结构和功能上的改变。对两个单侧腭裂标本头部和两个双侧腭裂标本头部的面部肌肉组织进行了解剖，并对口轮匝肌进行了宏观和局部检查。我们发现口轮匝肌的附着点发生了变化。对口轮匝肌与其他面部肌肉的正确局部关系起共同作用的口角肌未发生改变。此外，我们还检查了肌肉的血管系统，其同样适应了改变后的情况。唇/颌/腭裂会导致口轮匝肌在解剖学、功能和细微结构上发生改变，而面部其他肌肉组织则保持不变。
